FZT689BTA Description

Short technical summary and product information.

The FZT689BTA from Diodes Incorporated is a 20V NPN medium power transistor designed for applications requiring high current gain and low saturation voltage. It comes in a SOT223 surface mount package.

 

Key electrical specifications include a collector-emitter breakdown voltage (BVCEO) of minimum 20V, a continuous collector current rating of 3A (8A peak pulse), and power dissipation up to 3W depending on mounting conditions. The DC current gain (hFE) is minimum 400 at 2A collector current and 2V VCE, while the collector-emitter saturation voltage is maximum 450mV at 3A with 20mA base current. Transition frequency is typically 150 MHz.

 

The transistor features a lead-free finish, is RoHS3 compliant, and halogen-free (Green device). It has a moisture sensitivity level of 1 per J-STD-020 and is compatible with reflow soldering. The FZT689BTA is complementary to the PNP type FZT789B. Applications include Darlington replacements and battery powered circuits.
