2SA1091, PNP Silicon Transistor, TO-92 Package

The 2SA1091 is a PNP silicon transistor housed in a compact TO-92 package, designed for high-voltage control applications such as plasma displays, Nixie tube drivers, and cathode ray tube brightness control. It features a high collector-base and collector-emitter voltage tolerance of 300 V, making it suitable for demanding applications. The transistor offers a low collector-emitter saturation voltage of -0.5 V (max) at a collector current of -10 mA, ensuring efficient performance. With a low collector output capacitance of 6 pF (typical), the 2SA1091 is also suitable for high-frequency applications. It is complementary to the 2SC2551 NPN transistor, allowing for effective push-pull configurations in amplifier circuits.
