BD135G Description

Short technical summary and product information.

The BD135G is part of ON Semiconductor's series of plastic medium-power silicon NPN transistors designed for audio amplification and driver applications. With a maximum collector-emitter voltage of 45V and continuous collector current of 1.5A, it can dissipate up to 12.5W at case temperature 25°C. The device offers a wide DC current gain range from 40 to 250 at typical operating points.

 

The TO-126 through-hole package provides reliable thermal performance with a junction-to-case thermal resistance of 10°C/W. The part is RoHS compliant, Pb-Free, and Halogen-Free, suitable for environmentally conscious designs. Its complementary PNP counterparts include BD136G, BD138G, and BD140G.

 

Designed for medium-power applications, the BD135G operates over a junction temperature range of -55°C to 150°C. The collector-emitter saturation voltage is typically 500mV at 500mA, ensuring efficient switching in driver circuits.
