BD238

The BD238 is a PNP silicon epitaxial-base power transistor housed in a Jedec SOT-32 plastic package. It is designed for medium power linear and switching applications, including audio amplifiers and general-purpose drivers. Key electrical characteristics include a minimum collector-emitter sustaining voltage (VCEO(SUS)) of -80V and a minimum DC current gain (hFE) of 40 at an IC of -0.15A. The transistor also offers a typical transition frequency (FT) of 150MHz. Its maximum emitter-base voltage is rated at 5V. The BD238 is suitable for applications requiring reliable power handling capabilities in a compact package.

This power transistor is part of the BD Series, known for its performance in power applications. The SOT-32 package is a common surface-mount or through-hole component, facilitating integration into various circuit designs. Its PNP polarity makes it suitable for specific circuit configurations where a P-type semiconductor is required for switching or amplification.

Applications for the BD238 include audio amplifiers, drivers, and general-purpose switching circuits. Its specifications make it a versatile component for engineers designing power management systems and audio output stages. The material is silicon, ensuring robust performance characteristics.
