Product details

Overview

SFS1006G from Taiwan Semiconductor is a 10A, 400V repetitive peak reverse voltage (V_RRM) super fast surface-mount rectifier in TO-263AB (D2PAK) package, featuring 1.300V max forward voltage at 5A/25°C, 35ns reverse recovery time, and dual-die configuration for high-efficiency DC/DC and switching-mode power conversion.

For engineers reviewing the SFS1006G datasheet, SFS1006G pinout, SFS1006G application, or SFS1006G equivalent, key selection factors include its 400V V_RRM, 125A I_FSM, 2°C/W R_θJC, JESD201 Class 2 whisker resistance, and RoHS/halogen-free compliance for industrial-grade power supply designs.

Technical Context

The SFS1006G integrates two independent high-speed silicon rectifier dies in a single TO-263AB thermally optimized package, enabling bidirectional or dual-output freewheeling paths. Its 35ns trr and low 1.300V V_F support high-frequency switching up to several hundred kHz in synchronous rectification and flyback topologies.

Rated for continuous operation from –55°C to +150°C junction temperature, the device uses matte tin-plated leads compliant with J-STD-002 solderability and meets UL 94V-0 flammability requirements - critical for compact, convection-cooled power modules requiring long-term thermal reliability.

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-10EWH04-M3	Same 400V V_RRM, 10A I_F, but TO-220AC package; 1.25V V_F @ 5A; 30ns t_rr; no dual-die structure	Requires through-hole mounting and separate heatsink; unsuitable for ultra-thin SMT-only designs	Select when mechanical mounting flexibility outweighs board space and thermal integration needs
ON Semiconductor MUR1040CT	400V V_RRM, 10A I_F, TO-220AB package; dual common-cathode configuration; 1.3V V_F; 60ns t_rr	Higher t_rr increases switching loss above 50kHz; larger footprint than D2PAK	Prefer for cost-sensitive legacy designs where 60kHz+ operation is not required

Compared with VS-10EWH04-M3 and MUR1040CT, the SFS1006G delivers superior thermal integration via its D2PAK thermal pad and faster recovery for high-frequency operation, while maintaining identical voltage/current ratings - making it optimal for space-constrained, high-efficiency SMT power supplies.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) of the SFS1006G?

The SFS1006G has a V_RRM rating of 400 V, as confirmed in the Absolute Maximum Ratings table across all versions of the SFS1001G–SFS1008G datasheet. This value is fixed per part number suffix and verified for continuous operation at T_A = 25°C with derating above that temperature.

Does the SFS1006G have a dual-die configuration, and how is it implemented?

Yes, the SFS1006G uses a dual-die configuration housed in a single TO-263AB (D2PAK) package. The datasheet explicitly states "Configuration: Dual dies" and shows identical electrical specs across both dies - enabling use as two independent 400V/10A rectifiers or as a common-cathode pair without external paralleling.

What is the forward voltage (V_F) specification for the SFS1006G at rated current?

The SFS1006G has a maximum forward voltage of 1.300 V at I_F = 5 A and T_J = 25°C, per the Electrical Specifications table. This value applies to each die individually and is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects.

Is the SFS1006G suitable for surface-mount reflow assembly without moisture preconditioning?

Yes, the SFS1006G carries J-STD-020 Moisture Sensitivity Level 1, meaning it may be mounted directly using standard reflow profiles without baking or dry-pack handling. This is confirmed in the FEATURES section and supported by its TO-263AB packaging process.

What thermal resistance does the SFS1006G exhibit from junction to case?

The SFS1006G has a typical junction-to-case thermal resistance (R_θJC) of 2°C/W, as published in the Thermal Performance section. This value assumes proper soldering of the exposed cathode tab to a minimum 100 mm² copper area on the PCB, enabling efficient heat transfer to the board.
