A940 is a TO-220 packaged PNP BJT transistor. This article is going to explain pinout, features, applications, equivalents, and other details about the A940 transistor.
A940C
2SA940 is a PNP BJT transistor in a TO-220 package. This transistor is intended for general-purpose amplification and vertical output circuits, although it is not confined to these applications and can be utilized in a wide range of other applications. It also has a fast switching capability, which makes it excellent for applications that require quick switching. It can drive a maximum load of -1.5A and a maximum load voltage of -150V when used as a switch.

The A940 is primarily intended for use in vertical output circuitry and general-purpose audio amplification, although it is not confined to these uses and can be utilized for a wide range of other applications. It can also be used as a switch to drive a wide range of loads under -1.5A, such as high-power transistors, high-power LEDs, Relays, ICs, and circuit components. Its general-purpose audio amplification applications include audio amplifiers and high-power audio amplifier stages.
It is recommended that you do not utilize a component to its absolute maximum ratings and instead use it 20 percent below those ratings for long-life performance. The same is true for the A940 transistor; the transistor's maximum collector current is -1.5A, therefore do not drive a load of more than 1.2A. Because the maximum collector to emitter voltage is -150V, do not drive loads higher than -120V. Use a proper heat sink with the transistor, and always store or operate it at temperatures between -55 and +150 degrees Celsius.
