2SA1943-O Description

Short technical summary and product information.

The Toshiba 2SA1943-O is a PNP bipolar junction transistor (BJT) suitable for high-power amplification applications. It is housed in a TO-3PL package and offers a collector-emitter breakdown voltage (Vceo) of 230V and a continuous collector current (Ic) of 15A. With a power dissipation (Pd) of 150W, this transistor is designed for demanding audio power amplifier output stages and other circuits requiring significant current handling capabilities with low distortion.

 

Key electrical characteristics include a typical DC current gain (hFE) of 80 at 1A and 5V, and a typical collector-emitter saturation voltage (Vce(sat)) of 1.5V at 8A and 800mA. The transition frequency (fT) is 30MHz, and the collector cut-off current (Icbo) is 5uA.

 

This component is typically used in the output stages of audio amplifiers, finding application in both consumer and professional audio equipment. Its robust specifications make it suitable for designs where high current output and reliability are paramount. Proper heat sinking and biasing are essential for optimal performance and longevity, especially in high-power applications.
