BUX41N Description

Short technical summary and product information.

The BUX41N is a silicon NPN power transistor manufactured by ST, designed for high-speed, high-current, and high-power applications. It features a minimum collector-emitter voltage of 160V and a continuous collector current capability of 18A, with a peak capability of 25A. The device can dissipate up to 120W of power at a case temperature of 100℃.

Key electrical characteristics include a DC current gain ranging from 15 to 45 at 8A and 4V, and a current-gain-bandwidth product of 8 MHz at 1A and 15V. Switching times are also specified, with turn-on time at 1.3 μs, storage time at 1.5 μs, and fall time at 0.8 μs under specific test conditions.

Thermal management is crucial for this power transistor, with a junction-to-case thermal resistance of 1.46 ℃/W. The maximum junction temperature is 200℃, and the storage temperature range is -65℃ to 200℃. These specifications make the BUX41N suitable for demanding power applications where reliability and performance are critical.
