BUX20 Description

Short technical summary and product information.

The BUX20 from Semelab is a silicon multi-epitaxial planar NPN transistor housed in a modified TO-3 metal case. It is engineered for demanding switching and linear applications within military and industrial equipment.

 

Key electrical specifications include a collector-emitter voltage (VCEO) of 160V, a continuous collector current (IC) of 50A, and a peak collector current (ICM) of 60A. The device offers a total power dissipation (Ptot) of 350W at 25°C case temperature. Its junction temperature (TJ) can reach up to 200°C, with storage temperatures ranging from -65°C to 200°C.

 

The transistor is suitable for high-current, high-speed, and high-power applications. The TO-3 (TO-204AA) package is designed for through-hole mounting, with Pin 1 designated as the Base, Pin 2 as the Emitter, and the Case serving as the Collector.
