The FGAF30S65AQ is a silicon carbide (SiC) MOSFET from onsemi, belonging to the AEC-Q101 qualified automotive-grade family. It features an N-channel enhancement mode configuration housed in a TO-247-4 package. The device is rated for a drain-source voltage of 650 V and offers a continuous drain current capability of 30 A at 25°C. Key electrical parameters include a maximum gate-source voltage of ±20 V and a typical on-resistance significantly lower than comparable silicon devices. The component supports high-temperature operation with a maximum junction temperature rating of 175°C, designed for robust performance in demanding power conversion environments.
Verify the specific ordering suffix against the official datasheet to confirm packaging type and tape-and-reel specifications. Ensure the component meets the required AEC-Q101 reliability standards for your target application. Cross-reference the manufacturer's latest documentation for any updates regarding pinout or thermal characteristics before finalizing procurement.
Select this component when high-frequency switching and low conduction losses are critical. Consider the thermal resistance values provided in the datasheet to design appropriate heatsinking. Evaluate the gate charge requirements against your driver capabilities to optimize switching speed and minimize losses during transitions.
This part belongs to onsemi's portfolio of automotive-grade silicon carbide MOSFETs.
