BD138 PNP Power Transistor 60V 1.5A TO-126

From the shop's description

BD138 PNP Power Transistor 60V 1.5A TO-126 The BD138 is a robust PNP silicon epitaxial planar bipolar junction transistor (BJT) designed for medium-power linear and switching applications. It is housed in a standard TO-126 through-hole plastic package that supports reliable thermal performance and ease of handling in prototypes and production circuits. The device features a maximum collector-emitter voltage of 60 V, continuous collector current of 1.5 A, and moderate power dissipation, making it suitable for general amplifier, driver, and switching applications. Features: PNP epitaxial silicon construction for high reliability. Medium power handling with 1.5A continuous collector current. Low collector-emitter saturation voltage for efficient switching. Wide DC current gain (hFE) range from 40 to 250.
