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 up to 500 mW, 50 to 100 MHz transition frequency, DC current gain up to 800, max noise voltage of 40 mV, etc. The transistor is 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 use transistor for the safety and for getting full result
It is best to use all the transistors at least 20% below their absolute maximum ratings, and hence the same applies to the KSA992 transistor. The max collector current is -50 mA; therefore, do not drive a load of more than 40-55 mA. 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.
