During an avalanche, electrons in the P-N transition regions are accelerated to energies so high that they dataseet bound electrons with enough force to free them, creating additional charge carriers and greatly multiplying the transistor current.

A junction transistor is a sandwich of “N” and “P” type semiconductors. They also have double the input voltage drop since there are two semiconductor junctions in series.

2SC – Transistors

The following electrical specs trandistor important when choosing a substitute BJT. Field-effect transistors come in three basic types: 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. Current gain is only occasionally significant when choosing a substitute transistor. V CB is always equal to or greater than V CE and you can use either trahsistor these maximum voltages to compare transistors.

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. There are three breakdown voltages: One measure transietor gain, called h FEis often used for comparing transistors. Actual circuit gain depends on other components.


Just use a bit of spaghetti tubing on the leads to keep them from touching each other. It’s a maximum current rating so choose a substitute with a rating at least as high as the original.

This is the same spec used for bipolar transistors. The original transistor might need special ordering, or be discontinued and unavailable.

One of the following breakdown voltages is usually included in the specifications for a FET:. Some TO numbers are shown here:. In that case, the product’s Service Manual or Parts List might dattasheet you with the transistor type. This is the only transisfor you can actually see. Knowing how to substitute an alternate transistor type can speed up your repair, or make an otherwise impossible repair possible.

At the maximum voltage, also called a breakdown voltage BVelectrons begin to avalanche in the transistor. You can use either of the above voltages when comparing FETs. Either the “meat” has extra negative charge transiistor electrons and the “bread” has extra positive charge carriers holesor the meat has the positive charges and the bread has the negative charges.

Just make sure to compare apples with apples. If you install the wrong polarity, the sandwich won’t work. But if the original transistor has a high gain, try to match datassheet. A TO-5 transistor with a P D of 3 watts might be able to dissipate watts with a heat sink.

Then, when you need to pick a substitute for an original transistor, you can quickly home in on all your potential candidates. A Transistor Outline number, or TOrefers to a transistor’s physical size, shape, and mounting style.

However, the transistor’s data sheet will show you that. Choose a substitute with a rating at least as high as datashset original. Choose a substitute transistor with a breakdown voltage rating at least as high as the original. It’s the direct current that flows into the drain terminal when the transistoor to source voltage is zero. The first spec to consider is the Transistor Outline. 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.


So, altogether, there are six types of field-effect transistors. Be sure to choose a substitute transistor with a maximum current rating at least as high as the original.

You’ll find that fewer devices need to be stocked, and turnaround time can be reduced. In each of these ratings, the 3rd terminal is assumed to be electrically open unconnected. Today, FET acronyms 2sd9014 but they usually signify only how the FET is constructed or improved upon; they don’t describe another basic type.

Minimum and maximum values are usually given. The V EB rating isn’t usually a factor in choosing a substitute transistor.

Each of the three types listed above can be fabricated with either an N or a P conduction channel. The type number is often printed on the transistor, although product manufacturers sometimes have their own part numbers printed instead.

You can find transistor specs in data sheets available online. In an enhancement type device, it’s an off-state current. P D is the overall power the FET can dissipate through heat. More time is spent figuring out which one to replace and, sometimes, what to replace it with! Maximum current is the maximum continuous transisor current I C that a transistor can withstand without permanent damage.
