FZT657TA Description

Short technical summary and product information.

The FZT657TA is a 300V NPN bipolar junction transistor from Diodes Incorporated, designed for medium power high voltage applications. It offers a collector-emitter voltage (VCEO) of 300V and continuous collector current of 0.5A, with peak pulse current capability of 1A. The device features a DC current gain (hFE) of 50 minimum at 100mA, 5V, and a transition frequency of 30MHz.

 

Designed for surface mount assembly, the FZT657TA is housed in the SOT223 package (TO-261AA) with a weight of 0.112g. It supports a wide operating temperature range from -55°C to 150°C junction temperature. The package has a maximum power dissipation of 3W at 25°C ambient (note 6) and typical 2W under standard conditions.

 

This transistor is qualified to AEC-Q101 automotive standards and is PPAP capable, making it suitable for automotive and industrial applications. It is RoHS compliant with lead-free matte tin finish, halogen and antimony free, and has MSL Level 1 moisture sensitivity. The device is also complementary to the PNP type FZT757.
