BD242 Description

Short technical summary and product information.

The BD242 from STMicroelectronics is a PNP Silicon Power Transistor. It is designed for complementary applications alongside the BD241 series transistors. This component is rated for a continuous collector current of 3A and a peak collector current of 5A. It can dissipate up to 40W of power at a case temperature of 25°C, with linear derating to 150°C.

 

The transistor features a collector-emitter voltage rating (V_CER) of up to -115V depending on the variant (BD242C) and a collector-emitter voltage rating (V_CEO) of up to -100V (BD242C). The operating junction temperature range is from -65°C to +150°C.

 

Packaged in a TO-220 case, the BD242 is suitable for through-hole mounting. Its specifications make it a robust choice for power amplification and switching applications where complementary PNP transistors are required.
