The 2STA1943 is a high-power PNP epitaxial planar bipolar transistor from STMicroelectronics, designed for linear amplifier applications. It features a collector-emitter breakdown voltage of -230V and a continuous collector current rating of -15A, with peak current capability up to -30A. The device offers a typical transition frequency of 30MHz and a DC current gain range of 80 to 160 at 1A.
This transistor is housed in a TO-264 through-hole package, providing excellent thermal performance with a junction-to-case thermal resistance of 0.83°C/W. The maximum operating junction temperature is 150°C, and the storage temperature range is -55°C to 150°C.
The 2STA1943 is complementary to the 2STC5200 NPN transistor, making it suitable for push-pull audio power amplifier stages. Its fast switching characteristics and good gain linearity support high-fidelity audio output designs.
