KSA992 Transistor Pinout, Features and uses

In this article we are going to explain the 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 available in package TO-92. This transistor has 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 up to 800, max noise voltage is 40mV, etc. The transistor basically designed for low noise audio amplification but due to its good features it can also be used in a 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 using transistor for the safety and for getting the full result

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