BU941ZP Description

Short technical summary and product information.

The BU941ZP is a high voltage NPN Darlington transistor manufactured by STMicroelectronics using Multiepitaxial Planar technology. It is designed for automotive electronic ignition power actuators. Key specifications include a maximum collector-emitter voltage of 350V, continuous collector current of 15A (peak 30A), and a minimum DC current gain of 300 at 5A. The device features built-in clamping Zener for ruggedness and high operating junction temperature up to 175°C. It comes in a TO-247-3 through-hole package with a maximum power dissipation of 155W at case temperature 25°C. The fully insulated package is UL compliant for easy mounting. Typical applications include high ruggedness electronic ignitions.
