Product details
Overview
SFAF1006GH from Taiwan Semiconductor is a 10 A, 400 V repetitive peak reverse voltage (VRRM) super fast rectifier diode in ITO-220AC package, featuring 1.300 V forward voltage at 10 A and 25°C, 35 ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in high-frequency DC-DC converters.
For engineers reviewing the SFAF1006GH datasheet, SFAF1006GH pinout, SFAF1006GH application, or SFAF1006GH equivalent, key selection criteria include its 400 V VRRM, 150 A non-repetitive surge rating, 4 °C/W junction-to-case thermal resistance, AEC-Q101 qualification status, and ITO-220AC mounting compatibility with standard heatsinks.
Technical Context
This super fast rectifier uses a glass-passivated silicon die optimized for switching-mode power supplies operating above 50 kHz. Its 35 ns trr and low Qrr minimize switching losses during freewheeling and flyback transitions, while the 1.300 V VF balances conduction loss and thermal performance at 10 A DC.
The ITO-220AC package provides direct metal tab thermal path to heatsink, enabling stable operation up to 150°C junction temperature. AEC-Q101 qualification confirms robustness against temperature cycling, mechanical shock, and humidity exposure required for under-hood automotive power modules.
Key Specifications

| IFSM | 150 A - Single half-sine surge capability; withstands inrush and fault currents without failure |
| VF @ 10 A, 25°C | 1.300 V - Forward conduction loss determines power dissipation (13 W at 10 A) and thermal design margin |
| trr | 35 ns - Reverse recovery time directly impacts switching loss and EMI in >100 kHz topologies |
| RθJC | 4 °C/W - Junction-to-case thermal resistance enables predictable heatsink sizing for TJ ≤ 150°C |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R04DJF | 400 V VRRM, 10 A IF, 30 ns trr, TO-220AC package, no AEC-Q101 qualification | Higher speed but lacks automotive qualification; suitable for industrial/commercial SMPS only | Select when lower trr is prioritized over automotive compliance |
| VS-10EWH04-M3 | 400 V VRRM, 10 A IF, 35 ns trr, ITO-220AC, AEC-Q101 qualified, VF = 1.35 V (max) | Same qualification and package; slightly higher VF increases conduction loss by ~0.5 W at 10 A | Select when second-source availability or Vishay supply chain preference applies |
Compared with STTH10R04DJF and VS-10EWH04-M3, the SFAF1006GH delivers identical 400 V/10 A/35 ns performance with AEC-Q101 validation and lower typical VF (1.300 V vs. 1.35 V), making it optimal for thermally constrained automotive power rails requiring certified reliability.

FAQ
What is the peak repetitive reverse voltage rating of the SFAF1006GH?
The SFAF1006GH has a repetitive peak reverse voltage (VRRM) rating of 400 V, verified per the manufacturer's absolute maximum ratings table. This value defines the maximum reverse-biased voltage the device can block continuously without breakdown and is confirmed across all production lots and temperature ranges specified in the datasheet.
Is the SFAF1006GH qualified to AEC-Q101 standards?
Yes, the SFAF1006GH is explicitly AEC-Q101 qualified, as indicated by the "H" suffix in its ordering code and confirmed in the FEATURES section and ORDERING INFORMATION table. This qualification covers stress tests including temperature cycling, humidity bias, and mechanical shock per AEC-Q101 Rev D requirements.
What is the forward voltage drop of the SFAF1006GH at rated current?
The SFAF1006GH exhibits a typical forward voltage (VF) of 1.300 V at 10 A and 25°C, as specified in the ELECTRICAL SPECIFICATIONS table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents the conduction loss used for thermal and efficiency calculations in power supply designs.
Does the SFAF1006GH have a defined reverse recovery time?
Yes, the SFAF1006GH has a maximum reverse recovery time (trr) of 35 ns, tested under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This parameter is critical for minimizing switching loss and EMI in high-frequency DC-DC converters and is consistent across the SFAF1005G–SFAF1008G group.
What package type does the SFAF1006GH use, and how is polarity marked?
The SFAF1006GH uses the ITO-220AC package with an isolated metal tab serving as the cathode terminal. Polarity is marked on the device body per the MARKING DIAGRAM: "SFAF1006GH" text identifies the part, and the cathode band is indicated adjacent to the tab side, consistent with industry-standard diode marking conventions.
