2SA1213
The 2SA1213 is a PNP bipolar transistor designed for fast-switching and power amplification in electronic circuits. Encased in a SOT-89 surface-mount package, it supports a collector-emitter voltage of –50 V and a collector current of 1 A, with a low saturation voltage of –0.5 V at 1 A. Its typical switching time of 1.0 µs allows reliable operation in high-frequency and power-sensitive applications such as LED drivers, audio amplifiers, automotive modules, and industrial control circuits.
The transistor offers efficient performance with a low collector-emitter saturation voltage and sufficient current handling for standard power circuits. Its fast switching capability makes it suitable for pulse-width modulation and power supply applications. The 2SA1213 can be paired with its complementary 2SC2873 NPN transistor for balanced circuit designs.
The device is RoHS-compliant and fits on compact PCBs thanks to its SOT-89 package. Its thermal characteristics allow up to 2 W of power dissipation depending on mounting conditions, supporting applications in industrial and commercial electronics.
