Product details
Overview
SFS1008G from Taiwan Semiconductor is a 10A, 600V super fast surface-mount rectifier in TO-263AB (D2PAK) package, featuring 1.700V max forward voltage at 5A/25°C, 35ns reverse recovery time, and dual-die configuration for high-efficiency DC-DC converters and switching inverters.
For engineers reviewing the SFS1008G datasheet, SFS1008G pinout, SFS1008G application, or SFS1008G equivalent, key selection criteria include peak reverse voltage rating (600V), thermal resistance (2°C/W), surge capability (125A), junction temperature limit (+150°C), and RoHS/halogen-free compliance for industrial power designs.
Technical Context
The SFS1008G implements a dual-die super fast recovery rectifier architecture optimized for high-frequency switching topologies. Its 35ns trr and low 1.700V VF at 5A enable reduced conduction and switching losses in SMPS primary-side freewheeling and output rectification stages.
Thermally, it delivers 2°C/W junction-to-case resistance in TO-263AB package with matte tin-plated leads compliant to J-STD-002, supporting continuous 10A operation up to +150°C junction temperature under proper heatsinking.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-10EWH06-M3 | 600V VRRM, 10A IF, 35ns trr, TO-263AB, VF = 1.75V max @ 5A | Higher VF increases conduction loss by ~3% at full load; identical thermal and surge specs | Preferred where Vishay supply chain alignment or qualification history is required |
| ON Semiconductor MUR1060CT | 600V VRRM, 10A IF, 60ns trr, TO-220AC, VF = 1.7V max @ 5A | Slower recovery (60ns vs 35ns) raises switching loss; through-hole TO-220AC requires different layout and thermal management | Consider only if TO-220 footprint is fixed and switching frequency ≤ 100 kHz |
Compared with VS-10EWH06-M3 and MUR1060CT, the SFS1008G offers the lowest trr among 600V/10A D2PAK rectifiers and superior moisture robustness (MSL-1), making it optimal for high-frequency, high-reliability SMT power conversion where thermal performance and assembly simplicity are critical.

FAQ
What is the maximum junction temperature rating for the SFS1008G?
The SFS1008G has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet Version I2103. This rating permits continuous operation in high-ambient environments when mounted on a heatsink or thermally enhanced PCB, provided case temperature remains within limits defined by its 2°C/W RθJC.
Does the SFS1008G have a specified reverse recovery time (trr)?
Yes, the SFS1008G specifies a maximum reverse recovery time (trr) of 35 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as confirmed in the Electrical Specifications section of the Taiwan Semiconductor datasheet. This value applies directly to the SFS1008G variant and is lower than earlier family members (e.g., SFS1001G–SFS1004G).
Is the SFS1008G pin-compatible with other parts in the SFS100xG series?
Yes, all SFS100xG devices-including SFS1008G-share identical TO-263AB (D2PAK) package dimensions, pinout, and terminal configuration (anode lead, cathode tab). Mechanical data and suggested pad layout in the datasheet confirm full physical compatibility across the series for drop-in voltage-grade substitution.
What is the forward voltage (VF) specification for the SFS1008G at rated current?
The SFS1008G has a maximum forward voltage (VF) of 1.700 V at IF = 5 A and TJ = 25°C, as stated in the Electrical Specifications table for SFS1007G/SFS1008G. This value reflects worst-case conduction loss under standard test conditions and is measured per pulse test (PW = 0.3 ms).
Is the SFS1008G compliant with RoHS and halogen-free standards?
Yes, the SFS1008G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. The "G" suffix denotes green (halogen-free) molding compound, and the device carries J-STD-020 MSL-1 classification for moisture sensitivity.
