KSA992 Transistor Pinout, Features and uses

In this article we are going to explain KSA992 transistor pinout, equivalents, uses, specs and other important and useful information about this high gain and low noise transistor. The Transistor  is a high gain and low noise PNP transistor availabe in pacage TO-92. This transistor having quite good specs such as up to -120V collector to base voltage, collector power is upto 500mW, 50 to 100MHZ transition frequency, DC current gain of upto 800, max noise voltage is 40mV etc. The transistor basicaly designed for low noise audio amplification but due to its good features it can also be used in wide variety of other applications such as any type of low gain signal amplification in electronics.

Absolute Maximum Ratings/ Safe Operating Guidelines 

Must keep in mind the flowing instructions before use transistor for the safty and for getting full result

It is the best to use all the transistors atleast 20% below from its absolute maximum ratings and hence same applies to KSA992 transistor. The max collector current is -50mA therefore do not drive load of more than 40-55mA. The maximum collector to emitter voltage is -120V therefore do not drive load of more than -90-96V and always store or operate the transistor at temperatures above -55°C and below +150 °C.
