BU204 Description

Short technical summary and product information.

The BU204 from Telefunken is an NPN power transistor designed for specialized applications. It features a high collector-emitter voltage (VCEO) of 600V and a collector-emitter voltage under cutoff conditions (VCEX) of 1300V, making it suitable for high-voltage circuits.

This transistor can handle a continuous collector current (IC) of up to 2.5A and a peak current of 3.0A, with a continuous base current (IB) of 1.0A. The DC current gain (hFE) ranges from 15 to 60 at an IC of 2.0A and VCE of 5.0V. It also offers a typical gain-bandwidth product (fT) of 4MHz and an output capacitance (Cob) of 50pF.

With a total power dissipation of 36W at 25°C, the BU204 is designed for robust performance. It operates within a wide temperature range of -65°C to +115°C. The device comes in a TO-3 package, suitable for through-hole mounting.

Available options include high-reliability screening per MIL-PRF-19500, JANTX level, by adding an 'HR' suffix. It can also be specified as non-RoHS (Sn/Pb plating) or RoHS compliant by adding a '-PBF' suffix.
