BD438S Description

Short technical summary and product information.

The BD438S is a PNP bipolar junction transistor designed for general-purpose switching and amplification applications. Manufactured by On Semiconductor, it offers a maximum collector-emitter voltage of 45V and a continuous collector current rating of 4A.

 

With a maximum power dissipation of 36W, this transistor can handle moderate power levels. It has a typical transition frequency of 3 MHz, making it suitable for low-frequency switching circuits. The DC current gain (hFE) is a minimum of 30 at 10mA collector current and 5V Vce, and the collector-emitter saturation voltage is 600mV maximum at 200mA base current and 2A collector current.

 

The device is housed in a TO-225AA / TO-126-3 through-hole package, which allows for easy mounting on printed circuit boards. The operating junction temperature range extends up to 150°C. The BD438S is compliant with RoHS and REACH regulations, and has an MSL rating of 1 (unlimited).
