The FZT957TA is a PNP silicon planar high-performance bipolar transistor from Diodes Incorporated, designed for high current switching and driver applications. It features a 300V collector-emitter breakdown voltage (V(BR)CEO) and a continuous collector current rating of 1A, with a peak pulse current capability of 2A.
This transistor offers very low collector-emitter saturation voltage of 240mV max at 300mA base current and 1A collector current, ensuring efficient operation in saturated switching circuits. The DC current gain (hFE) is specified at a minimum of 100 at 500mA and 10V, with useful gain maintained up to 2A, making it suitable for both linear and switching applications.
The device is housed in a SOT223-3 surface mount package (equivalent to TO-261-4), which provides a compact footprint for space-constrained designs. Power dissipation is rated at 3W when mounted on a PCB with adequate copper area. The FZT957TA has a transition frequency of 85MHz, supporting moderate speed switching applications.
Typical applications include medium speed switching, driver stages, and power management circuits where PNP polarity is required. The complementary NPN type is FZT857, allowing use in push-pull and half-bridge topologies. Operating temperature range spans from -55°C to 150°C, suitable for industrial and automotive environments.
