Datasyeet and replacing a transistor takes very little time. More time is spent figuring out which one to replace and, sometimes, what to replace it with! The original transistor might need special ordering, or be discontinued and unavailable.

Knowing how to substitute an alternate transistor type can speed up your repair, or make an otherwise impossible repair possible.

The type number is often printed on the transistor, although product manufacturers sometimes have their own part numbers printed instead. In that case, the product’s Service Manual or Parts List might provide you catasheet the transistor type.

If you don’t have that particular type, a transistor cross-reference guide can sometimes help you to find a compatible, generic part. But you might already have a suitable substitute in your parts drawers. You can find transistor specs in data sheets available online. The first spec to consider is the Transistor Outline. This is the only spec you can actually see. A Transistor Outline number, or TOrefers to a transistor’s physical size, shape, and mounting style.

Some TO numbers are shown here:.

The transistor outline doesn’t usually tell you which of the three transistor leads connects to its Base terminal Bits Emitter terminal Eor its Collector terminal C. However, the transistor’s data sheet will show you that. If the lead arrangement of a small replacement transistor differs from that of the the original, you can sometimes bend the transistor leads across one another to route them into the correct holes in the circuit board.

Just use a bit of spaghetti tubing on the leads to keep them from touching each other. Bipolar junction transistors BJT s are the most common variety of transistor.

The following electrical specs are important when choosing a substitute BJT. A junction transistor is a sandwich of “N” and “P” type semiconductors. Either the “meat” has extra negative charge carriers electrons and the “bread” has extra positive charge carriers holesor the meat has the positive charges and the bread has the negative charges. If you install the wrong polarity, the sandwich won’t work. If more than a maximum voltage rating is applied to a transistor, it can be permanently damaged.

At the maximum voltage, also called a breakdown voltage BVelectrons begin to avalanche in the transistor. During an avalanche, electrons in the P-N transition regions are accelerated to energies so high that they hit bound electrons with enough force to free them, creating additional charge carriers and greatly multiplying the transistor current.

In each of these ratings, the 3rd terminal is assumed to be electrically open unconnected. The V EB rating isn’t usually a factor in choosing a substitute transistor. V CB is always equal to transistro greater than V CE and you can use either of these maximum voltages to compare transistors.

Choose a substitute transistor with a breakdown voltage rating at least as high as the original. Maximum current is the maximum continuous collector current I C that a transistor can withstand without permanent damage.

Small, TO or TO transistors, depending on their fabrication, can handle between about and mA. Be sure to choose a substitute transistor with a maximum current rating at least as high as the original. Maximum Power, called P Dis the overall power a transistor can dissipate, through heat, without burning up. Heat sinks and fans increase the ability of a transistor to dissipate heat.

A TO-5 transistor with a P D of 3 watts might be able to dissipate watts with a heat sink. Choose a substitute transistor with a maximum power rating at least as high as the original. Current gain is only occasionally significant when choosing a substitute transistor. Actual circuit gain depends on other components.

But if the original transistor has a high gain, try to match it. Current gain falls off at higher frequencies, so a high-gain transistor can deliver a wider frequency response than a low-gain transistor. One measure of gain, transistog h FEis often used for comparing transistors. Data sheets often specify a minimum or typical value of h FEor else a range of values that applies at a certain collector current I C. They also have double the input voltage drop since there are two semiconductor junctions in series.

It’s not a good idea rransistor substitute a Darlington transistor for a non-Darlington type, or vice versa. Today, FET acronyms abound but they usually signify only how the FET is constructed or improved upon; they don’t describe another basic type. Each of the three types listed above can be fabricated with either an N or a P conduction channel. So, altogether, there are six types of field-effect transistors. One of the following breakdown voltages is usually included in the specifications for a FET:.

You can use either of the above voltages when comparing FETs. Just make sure to compare apples with apples. Pick a substitute FET with a rating at least as high as the original. It’s the direct current that flows into the drain terminal when the gate to source voltage is 2sc90014.

In datasheeh depletion type device, I DSS is an on-state current. In an enhancement type device, it’s an off-state current. Minimum and maximum values are usually given. Select a substitute with the same general range of values. It’s a maximum current rating so choose a substitute with a rating at least as high as the original.

P D is the overall power the FET can dissipate through heat. This is the same spec used for bipolar transistors. Choose a substitute with a rating at least as high as the original.

For a depletion-type FET, the gate-source bias voltage might be 0 V i. Finding a substitute replacement transistor isn’t difficult if you know the specs of the original transistor and organize your stock by specs instead of type numbers.

You’ll find that fewer devices need to be stocked, and turnaround time can be reduced. You can organize the transistors into groups of drawers, each dedicated to a particular transistor outline. Then, when you need to pick a substitute for an original transistor, you can quickly home in on all your potential candidates. Some TO numbers are shown here: There are three breakdown voltages: V CB – the maximum voltage across the Collector-Base terminals V CE – the maximum voltage across the Collector-Emitter terminals V EB – the maximum voltage across the Emitter-Base terminals In each of these ratings, the 3rd terminal is assumed to be electrically open unconnected.

Field-effect transistors come in three basic types: Be sure to substitute a FET of the same type as the original. One tgansistor the following breakdown voltages is trnsistor included in the specifications for a FET: BV GSS – the breakdown voltage between the Gate and the Source terminals when the drain is short-circuited to the source. This rating is used primarily with JFETs. BV DSS – the breakdown voltage between the Drain and the Source terminals when the gate is short-circuited to the source.
