BD136 PNP Bipolar Medium Power Transistor 45V 1.5A TO-126 Package

BD136 PNP Bipolar Medium Power Transistor 45V 1.5A TO-126 Package

The BD136 is a medium-power PNP silicon transistor designed for audio amplification, linear, and switching applications. With a collector-emitter voltage rating of 45V and a collector current of up to 1.5A, it provides excellent current handling, low saturation voltage, and stable performance across a wide operating range.

Encased in a TO-126 package, the BD136 ensures efficient heat dissipation, allowing reliable operation in medium-power circuits. It is commonly used in complementary pairs with the BD135 (NPN) for push-pull amplifier stages, making it ideal for audio systems, voltage regulators, and motor control circuits.
