The BD135 is a plastic medium-power NPN silicon transistor designed by On Semiconductor for general purpose amplifier and driver applications. It is rated for a collector-emitter voltage of 45 V, a maximum collector current of 1.5 A, and a power dissipation of 12.5 W when the case temperature is held at 25°C. The device is offered in a TO-225AA (TO-126-3) through-hole package, making it suitable for audio amplifiers, driver stages, and other medium-power linear circuits.
The transistor features high DC current gain, with a minimum of 40 at 150 mA collector current, and a low collector-emitter saturation voltage of 500 mV at 500 mA. It is complementary to the BD136, BD138, and BD140 PNP transistors, allowing straightforward implementation of complementary output stages. The part is Pb-free, halogen-free, and RoHS compliant.
For thermal management, the device has a junction-to-case thermal resistance of 10 °C/W and an operating junction temperature range of -55°C to +150°C. The standard shipping configuration is 500 units per box (Pb-free variant).
