BUL381 - NPN POWER TRANSISTOR

Download the BUL381 datasheet PDF. This datasheet also covers the BUL variant, as both devices belong to the same npn power transistor family and are provided as variant models within a single manufacturer datasheet.

General Description

The BUL381 and BUL382 manufactured using high voltage Multiepitaxial Mesa technology for cost-effective high performance.

They use a Hollow Emitter structure to enhance switching speeds.

The BUL series is designed for use in lighting applications and low cost switch-mode power supplies.
