Product details
Overview
SFS1003GH from Taiwan Semiconductor is a 150 V, 10 A super fast surface-mount rectifier in TO-263AB (D2PAK) package, featuring 35 ns reverse recovery time and 0.975 V forward voltage at 5 A/25°C, designed for high-efficiency DC-DC converters and automotive freewheeling paths.
For engineers reviewing the SFS1003GH datasheet, SFS1003GH pinout, SFS1003GH application, or SFS1003GH equivalent, key selection criteria include its AEC-Q101 qualification, 125 A surge rating, dual-die configuration, low RθJC of 2°C/W, and halogen-free, RoHS-compliant construction for automotive-grade reliability.
Technical Context
The SFS1003GH implements a single-die super fast recovery rectifier structure optimized for switching frequencies up to several hundred kHz. Its 150 V VRRM, 35 ns trr, and 0.975 V VF at 5 A enable efficient operation in flyback and boost topologies where low conduction loss and fast turn-off are critical.
Thermally, it delivers 2°C/W junction-to-case resistance in the TO-263AB package, supporting continuous 10 A operation with appropriate PCB copper area. The device operates across –55°C to +150°C junction temperature range and meets JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse blocking voltage; defines usable input voltage headroom in DC-DC stages |
| IF | 10 A - Continuous average forward current; sets minimum heatsinking requirement at rated ambient |
| IFSM | 125 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current handling |
| trr | 35 ns - Reverse recovery time; enables stable operation up to ~500 kHz switching without excessive switching loss |
| VF | 0.975 V @ 5 A, 25°C - Forward voltage drop per diode; directly determines conduction loss in high-current paths |
| CJ | 70 pF @ 1 MHz, 4 V - Junction capacitance; impacts EMI and snubber design in high-dV/dt applications |
| RθJC | 2 °C/W - Thermal resistance from junction to case; enables direct thermal interface to heatsink or large copper pour |
Pinout & Package
Package: TO-263AB (D2PAK), surface-mount, single-anode/single-cathode configuration with exposed cathode tab for thermal and electrical connection.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-10EWH06-M3 | 600 V VRRM, 35 ns trr, 0.95 V VF @ 5 A - higher voltage rating, slightly lower VF | Used in 400 V bus applications; not AEC-Q101 qualified | Select when >150 V blocking is needed and automotive qualification is not required |
| ON Semiconductor MUR1020CT | 200 V VRRM, 60 ns trr, 0.93 V VF @ 5 A - slower recovery, dual common-cathode configuration | Common in industrial SMPS; lacks AEC-Q101 and halogen-free certification | Select for cost-sensitive non-automotive designs where 60 ns trr is acceptable |
Compared with VS-10EWH06-M3 and MUR1020CT, the SFS1003GH uniquely combines AEC-Q101 qualification, 150 V rating optimized for 48 V automotive systems, and 35 ns recovery-making it the preferred choice for thermally constrained, safety-critical vehicle subsystems requiring validated reliability.

FAQ
What is the maximum junction temperature rating for the SFS1003GH?
The SFS1003GH has a maximum junction temperature (TJ) rating of +150°C, with operational range from –55°C to +150°C. This rating is validated under AEC-Q101 stress conditions and supports sustained 10 A conduction in automotive underhood environments when mounted on ≥10 cm² 2-oz copper with thermal vias. Derating begins above 100°C ambient per the forward current derating curve in the SFS1003GH datasheet.
Is the SFS1003GH pin-compatible with other devices in the SFS100xGH family?
Yes, all SFS1001GH through SFS1008GH share identical TO-263AB (D2PAK) package dimensions, pinout, and terminal configuration-including Anode (Lead 2), Cathode (Tab + Lead 3), and NC (Lead 1). Voltage ratings differ across the family (50–600 V), but mechanical and soldering compatibility is fully maintained for BOM flexibility and design reuse.
Does the SFS1003GH require special PCB layout considerations for thermal performance?
Yes-the SFS1003GH relies on its exposed cathode tab for primary heat dissipation. Optimal thermal performance requires ≥4 thermal vias (0.3 mm diameter) under the tab connecting to an internal or external ground plane, plus ≥10 cm² of 2-oz copper on the mounting layer. The SFS1003GH datasheet provides recommended pad layout and copper area guidelines to achieve the specified 2°C/W RθJC.
What does the "GH" suffix indicate in SFS1003GH?
The "GH" suffix in SFS1003GH denotes Taiwan Semiconductor's green halogen-free packaging standard: matte tin-plated leads, UL 94V-0 molding compound, and compliance with IEC 61249-2-21. It confirms full RoHS compliance and absence of brominated flame retardants or chlorine-based compounds-critical for automotive OEM environmental specifications.
How is the SFS1003GH marked on the device body?
The SFS1003GH is laser-marked with "SFS1003G" on the top surface, followed by a date code (YWW format) and factory code (e.g., "F"). The "G" indicates green/halogen-free status, consistent with TSC's marking convention across the SFS100xGH series. Polarity is indicated by a cathode band adjacent to Lead 3.
