BCX6925TA

Overview

The BCX6925TA is a PNP medium power transistor manufactured by Diodes Incorporated, housed in an SOT89 surface-mount package. It features a collector-emitter breakdown voltage of -20V and supports a continuous collector current of -1A with a peak pulse current capability of -2A. The device exhibits low saturation voltage, specified as less than -0.5V at -1A collector current. Electrical characteristics include a static forward current transfer ratio (hFE) ranging from 160 to 400 at -0.5A, and a transitional frequency of 100MHz. Thermal performance allows for 1W power dissipation within an operating temperature range of -55°C to +150°C.

Feature Summary

• Epitaxial planar die construction designed for automated assembly processes.
• Low saturation voltage characteristic suitable for efficient switching applications.
• High continuous current handling capability for medium power requirements.
• Fully lead-free and RoHS compliant with halogen and antimony-free green materials.

Applications

• Medium power switching circuits
