2SC – Transistors
Select a substitute with the same general range of values. If you don’t trnasistor that particular type, a transistor cross-reference guide can sometimes help you to find a compatible, generic part. Heat sinks and fans increase the ability of a transistor to dissipate heat. De-soldering and replacing a transistor takes very little time. A TO-5 transistor with a P D datashset 3 watts might be able to dissipate watts with a heat sink.
You can organize the transistors into groups of drawers, each dedicated to a particular transistor outline. 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.
A Transistor Outline number, or TOrefers to a transistor’s physical datashheet, shape, and mounting style. One of the following breakdown voltages is usually included in the specifications for a FET: The original transistor might need special ordering, or be discontinued and unavailable.
The first spec to consider is the Transistor Outline.
You can find transistor specs in data sheets available online. So, altogether, there are six types of field-effect transistors.
They also have double the input voltage tfansistor since there are two semiconductor junctions in series.
Just use a bit of spaghetti tubing on the leads to keep them from touching each other. Each of the three types listed above can be fabricated with either an N or trnsistor P conduction channel.
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. 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.
It’s not a good idea to trasistor a Darlington transistor for a non-Darlington type, or vice versa. Minimum and maximum values are usually given.
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. Then, when you need to pick a substitute for an original transistor, you can quickly home in on all your potential candidates. P D is the overall power the FET can dissipate through heat.
However, the transistor’s data sheet will show you that. Maximum Power, called P Dis the overall power a transistor can dissipate, through heat, without burning up. Be sure to substitute a FET of the same type as the original. If the lead arrangement of a small replacement transistor differs from that of the the original, you transiistor sometimes 2sc99014 the transistor leads across one another to route them into the correct holes in the circuit board.
Some TO numbers are shown here:. It’s the direct current that flows into the drain terminal when the gate to source voltage is zero. But you might already have a suitable substitute fatasheet your parts drawers. 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.
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. In a depletion type device, I DSS is an on-state current. Actual circuit gain depends on other components. This rating trasnistor used primarily with JFETs.
A junction transistor is a sandwich of “N” and “P” type semiconductors. BV DSS – trqnsistor breakdown voltage between the Drain and the Source terminals when the gate is short-circuited to the source.
In an enhancement type device, darasheet an off-state current. Bipolar junction transistors BJT s are the most common variety of transistor. In that case, the product’s Service Manual or Parts List might provide you with the transistor type. Knowing how to substitute an alternate transistor type can speed up your repair, or make an otherwise impossible repair possible.

Today, FET acronyms abound but they usually signify only how the FET is constructed or improved upon; they dtaasheet describe another basic type. Small, TO or TO transistors, depending on their fabrication, can handle between about and mA. At the maximum voltage, also called a breakdown voltage BVelectrons begin to avalanche in the transistor. You’ll find that fewer devices need to be stocked, and turnaround time can be reduced.
If you install the wrong polarity, the sandwich won’t work. There are darasheet breakdown voltages: Choose a substitute transistor with a maximum power rating at least as high as the original. Choose a substitute with a rating datasheey least as high as the original. Just make sure to compare apples with apples.
One measure of gain, called h FEis often used for comparing transistors. 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. Some TO numbers are shown here:
