SS9015 Transistor Explained / Description:

SS9015 is a well-known PNP silicon BJT transistor. This transistor is mainly designed for low gain signals amplification. Normally when a low gain signal is amplified to high gain then the noise with the signal is also get amplified but this transistor possess low noise feature which filters noise from the amplified signal and hence you will get a low noise and high gain signal at the output. The max collector dissipation of the transistor is 400mW that is enough to drive a small 2 to 3 inch 4Ohms or 8Ohms speaker directly if any small few milliwatt input signal is provided. Other than these uses it can also be used as a switch to drive loads under -100mA. The transition frequency is 150MHz due which it can also be used in RF circuits under 150 MHz frequency spectrum.



Where We Can Use it & How to Use:

SS9015 can be used for variety of applications like audio preamplification, audio amplification, amplifying any low gain signals to high gain, etc. Moreover it can also be used as a switch to drive relays, LEDs, high power transistors etc. This transistor can be used or wired same like any other BJT transistor.



Audio Preamplifiers

Audio Amplification Stages

Signal Amplifier

Hearing Aids

Sensor Circuits

Switching loads under 100mA

Darlington Pairs


How to Safely Long Run in a Circuit:

To get long term and good overall performance with SS9015 in your circuits it is recommended to not drive load of more than 100mA and the load voltage should be less than 45V. Use a suitable base resistor which provides the required input current to the transistor and always operate or store the transistor in temperature above -55 Celsius and below +150 Celsius.
