C9014 Datasheet, 2SC9014 PDF – NPN 50V TR – Usha
V CB – trnasistor 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. Then, when you need to pick a substitute for an original transistor, you can quickly home in on all your potential candidates. Choose a substitute transistor with a maximum power rating at least as high as datasheef original.
If the lead arrangement of a small replacement transistor differs from datashret 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.
You’ll find that fewer devices need to be stocked, and turnaround time can be reduced. Current gain falls off at higher frequencies, so a high-gain transistor can deliver a wider frequency response than a low-gain transistor.
More time is spent figuring out which one to replace and, sometimes, datasheft to replace it with! You can find transistor specs in data sheets available online. At the maximum voltage, also called a breakdown voltage BVelectrons begin to avalanche in the transsistor.
Today, FET acronyms abound but they usually signify only how the FET is constructed or improved upon; they don’t describe another basic type. V CB is always equal to or greater than V CE and you can use either of these maximum voltages to compare transistors. One of the following breakdown voltages is usually included in the specifications for a FET:.
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.
They also have double the input voltage drop since there are two semiconductor junctions in series. The type number is often printed on the transistor, although product manufacturers sometimes have their own part numbers dxtasheet instead. Just make sure to compare apples with apples. Knowing how to substitute an alternate transistor type can speed up your repair, or make an otherwise impossible repair possible.
Be sure to choose a substitute transistor with transitsor maximum current rating at least as high as the original. 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. The first spec to consider is the Transistor Outline. 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.
Each of the three types listed above can be fabricated with either an N or a P conduction channel. De-soldering and replacing a transistor takes very little time. For a depletion-type FET, the gate-source bias voltage might be 0 V i. Some TO numbers are shown here: If you install the wrong polarity, the sandwich won’t work. However, the transistor’s data sheet will show you that. Choose a substitute with a rating at least as high as the original. One of the following breakdown voltages is usually included in the datashset for a FET: If you don’t have that particular type, a transistor cross-reference guide can sometimes help you to find a compatible, generic part.
If more than a maximum voltage rating is applied to a transistor, it can be permanently damaged. BV DSS – the breakdown voltage between the Drain and the Source terminals when the gate is short-circuited to the source.
In each of these ratings, the 3rd terminal is assumed to be electrically open unconnected.
2SC – Transistors
A TO-5 transistor with a P D of 3 watts might be able to dissipate watts with a heat sink. There are three breakdown voltages: Current gain is only occasionally significant when choosing a substitute transistor. Select a substitute with the same general range of values.
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.
Maximum Power, called P Dis the overall power a transistor can dissipate, through heat, without burning up.
So, altogether, there are six types of field-effect transistors. In a depletion type device, I DSS is an on-state current. Minimum and maximum values are usually given. This is the same spec used for bipolar transistors. You can use either of the above voltages when comparing FETs.
