Taiwan Semiconductor Corporation SFA1008GH

Overview

SFA1008GH from Taiwan Semiconductor is a single-die AEC-Q101-qualified super fast rectifier in TO-220AC package, rated for 10 A average forward current, 600 V repetitive peak reverse voltage (V_RRM), and 125 A non-repetitive surge current (I_FSM). It delivers low reverse recovery time (35 ns) and forward voltage of 1.700 V at 10 A and 25°C, targeting high-efficiency DC/DC converters and switching inverters in automotive power systems.

For engineers reviewing the SFA1008GH datasheet, SFA1008GH pinout, SFA1008GH application, or SFA1008GH equivalent, key selection factors include its AEC-Q101 qualification, 600 V V_RRM, 35 ns trr, TO-220AC thermal resistance (3.5 °C/W), and junction temperature range (–55 to +150 °C).

Technical Context

This device operates as a unidirectional super fast recovery rectifier with optimized carrier lifetime control to achieve 35 ns reverse recovery time while maintaining low forward conduction loss. Its single-die TO-220AC construction supports direct heatsink mounting and handles 125 A surge under 8.3 ms half-sine conditions.

The SFA1008GH exhibits 50 pF junction capacitance at 1 MHz and 4.0 V reverse bias, and maintains IR ≤ 10 µA at 25°C and ≤ 400 µA at 100°C - critical for low-leakage operation in high-voltage hold-off stages of SMPS and freewheeling paths.

FAQ

What is the maximum junction temperature rating for the SFA1008GH?

The SFA1008GH has a maximum junction temperature (T_J) of +150 °C and a minimum of –55 °C, fully aligned with AEC-Q101 temperature cycling and storage requirements. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial enclosures. The SFA1008GH maintains specified electrical parameters across this full range when operated within its absolute maximum ratings.

Is the SFA1008GH pin-compatible with other devices in the SFA100xG series?

Yes, all SFA100xG and SFA100xGH devices share identical TO-220AC package dimensions, pinout (anode/cathode/tab), and mechanical mounting specifications. The SFA1008GH uses the same footprint and thermal interface as SFA1001GH through SFA1007GH, enabling voltage-scaling design reuse without PCB changes - only voltage rating and V_F differ across the family.

Does the SFA1008GH require a heatsink in typical 10 A operation?

Yes, the SFA1008GH requires a heatsink for sustained 10 A operation due to its 1.700 V forward voltage drop, generating ~17 W of power dissipation. With R_θJC = 3.5 °C/W and typical R_θCA of 15–25 °C/W for standard TO-220 heatsinks, junction temperature would exceed 150 °C without thermal management. The SFA1008GH is designed for direct-mount heatsinking per its TO-220AC mechanical data.

What does the "H" suffix in SFA1008GH signify?

Per Taiwan Semiconductor's ordering information, the "H" suffix in SFA1008GH explicitly denotes AEC-Q101 qualification. This means the SFA1008GH has undergone full stress testing per the AEC-Q101 standard for discrete semiconductors, including HTSL, TC, UHAST, and mechanical shock tests - distinguishing it from the non-H variant SFA1008G intended for commercial/industrial use only.

How does the SFA1008GH's reverse recovery time compare to standard fast rectifiers?

The SFA1008GH achieves 35 ns reverse recovery time (t_rr), which is approximately 3× faster than standard fast rectifiers (typically 100–150 ns) and 2× faster than many general-purpose ultrafast diodes. This enables higher switching frequencies and reduced EMI in power supplies. The SFA1008GH's t_rr is measured under standardized conditions (I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A), ensuring consistent benchmarking across designs.
