SFAF803GH

Single Diodes Overview

The SFAF803GH is a single super fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation. It features an 8A average forward current rating and a 150V repetitive peak reverse voltage. The device utilizes glass passivation for the chip junction to ensure high reliability and low leakage current. Designed for through-hole mounting, it employs the TO-220AC package with an isolated cathode configuration. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 125A and a typical reverse recovery time of 35ns. The component operates within a junction temperature range of -65°C to +150°C.

Single Diodes Procurement Notes

Verify the specific suffix GH indicates AEC-Q101 automotive qualification when sourcing. Confirm the manufacturer is Taiwan Semiconductor Corporation and not a generic distributor. Ensure the package matches the required TO-220AC form factor for your PCB layout. Check for RoHS compliance documentation if environmental regulations apply to your assembly process.

Single Diodes Selection Notes

Select this component when a super fast recovery time is critical for reducing switching losses in high-frequency circuits. The 8A current rating suits moderate power applications requiring reliable thermal performance. Consider the TO-220AC package for easy heat sinking via the isolated cathode. Verify that the 150V reverse voltage provides sufficient margin for your circuit's peak inverse voltage requirements.

Single Diodes Part Context

This part belongs to the SFAF series of super fast rectifiers from Taiwan Semiconductor. The series offers various voltage ratings from 50V to 600V while maintaining consistent 8A current handling. These devices are designed to replace standard fast recovery diodes where lower reverse recovery charge is needed. The SFAF803GH specifically targets the 150V segment of this lineup.

Single Diodes Replacement Considerations

Check for direct substitutes within the same SFAF series or equivalent parts from other manufacturers offering identical 8A/150V specifications. Ensure any replacement maintains the super fast recovery time and TO-220AC package compatibility. Verify pinout alignment, particularly regarding the isolated cathode configuration.
