FZT690BTA Description

Short technical summary and product information.

The FZT690BTA from Diodes Incorporated is an NPN bipolar junction transistor designed for medium-power switching and amplification applications. It features a collector-emitter breakdown voltage of 45 V and a continuous collector current rating of 3 A, with a peak current capability of 6 A. The transistor offers a high DC current gain (hFE) of at least 150 at 2 A, 2 V, and a typical collector-emitter saturation resistance of 125 mΩ at 2 A, enabling low on-state losses.

 

The device is supplied in a surface-mount SOT-223-3 package with gull-wing terminals, supporting standard reflow soldering processes. It has a wide operating junction temperature range from -55 °C to 150 °C and features a lead-free, halogen- and antimony-free green molding compound. The FZT690BTA is AEC-Q101 qualified for automotive reliability and is suitable for use in Darlington replacement, DC-DC converters, battery-powered circuits, and siren drivers.
