FZT749TA Description

Short technical summary and product information.

The FZT749TA is a PNP medium power transistor from Diodes Incorporated, designed for applications requiring high current and voltage handling. It features a collector-emitter breakdown voltage (VCEO) of -25 V minimum and a continuous collector current rating of -3 A. The device offers low saturation voltage, typically below -300 mV at -1 A collector current, enabling efficient switching performance.

 

Key electrical characteristics include a transition frequency of 160 MHz, making it suitable for high-speed switching applications. The transistor is rated for a peak pulse current of -8 A and has a maximum power dissipation of 3 W when mounted on a 50 mm² copper pad. Thermal resistance varies from 41.7 °C/W to 104 °C/W depending on PCB copper area.

 

The FZT749TA is housed in a surface-mount SOT223 package (SOT-223-3), which is RoHS3 compliant, halogen-free, and has an MSL of Level 1 (unlimited). It is ESD rated to 4000 V HBM (Class 3A) and 400 V MM. The device is complementary to the DIODES FZT649 NPN transistor. Applications include MOSFET and IGBT gate driving.
