SFF1003GH

Diode Arrays Overview

The SFF1003GH is a general-purpose fast recovery rectifier diode array manufactured by Taiwan Semiconductor Corporation. It features a common anode configuration with two internal diodes housed in an ITO-220AB (TO-220-3 Full Pack) through-hole package with an isolated tab. The device supports a maximum repetitive peak reverse voltage of 150 V and provides an average forward rectified current of 5 A per diode. Key electrical characteristics include a typical reverse recovery time of 35 ns, a maximum reverse leakage current of 10 µA at 150 V, and a forward voltage drop of 975 mV at 5 A. It operates within a junction temperature range of -55°C to 150°C and holds AEC-Q101 automotive qualification.

Diode Arrays Feature Summary

• Fast recovery performance with low reverse recovery time for efficient switching applications
• Automotive-grade reliability certified under AEC-Q101 standards
• Common anode dual-diode configuration simplifies circuit design
• High thermal stability with isolated tab packaging for effective heat dissipation

Diode Arrays Applications

• Automotive power supply circuits requiring high reliability
• DC-DC converter output rectification stages
• Freewheeling diode applications in inductive load driving
• General-purpose rectification in industrial electronics

Diode Arrays Procurement Notes

Verify the specific suffix GH against official datasheets to confirm package type and qualification status. Confirm availability as distribution status may vary. Ensure compatibility with existing PCB footprints for TO-220-3 full pack isolation. Check for RoHS compliance documentation if required by project specifications. Validate that the 150V rating meets system voltage requirements including transients.

Diode Arrays Selection Notes

Select this component when a common anode dual diode is required for 150V systems with moderate current demands up to 5A per leg. The fast recovery characteristic makes it suitable for higher frequency switching compared to standard rectifiers. Consider the TO-220AB package for board-mount applications needing robust mechanical fixation and thermal management via the isolated tab. Compare total power dissipation capabilities against heatsinking options in the final enclosure design.

Diode Arrays Part Context

This part belongs to the SFF series of fast recovery rectifiers from Taiwan Semiconductor. The series offers various voltage ratings and current capacities in both single and array configurations. The SFF1003 variant specifically targets 150V applications. The GH suffix typically denotes specific packaging or automotive qualification attributes within the manufacturer's lineup, distinguishing it from standard commercial grade parts.

Diode Arrays Replacement Considerations

Direct pin-compatible replacements should be sought within the same SFF series or equivalent fast recovery arrays from other manufacturers. Verify that substitute parts match the 150V reverse voltage, 5A current rating, and 35ns reverse recovery time. Ensure the replacement package maintains the isolated tab feature for proper mounting and insulation.
