Product details

Overview

SFS1002G from Taiwan Semiconductor is a 10A, 100V super fast surface-mount rectifier in TO-263AB (D2PAK) package, featuring 35ns reverse recovery time, 0.975V forward voltage at 5A/25°C, and 125A surge capability-used in DC-DC converters and switching inverters for high-efficiency power conversion.

For engineers reviewing the SFS1002G datasheet, SFS1002G pinout, SFS1002G application, or SFS1002G equivalent, key selection criteria include V_RRM = 100 V, I_F = 10 A, t_rr = 35 ns, R_θJC = 2 °C/W, and TO-263AB thermal performance for high-power density designs.

Technical Context

The SFS1002G integrates dual dies in a single TO-263AB package with common-cathode configuration, optimized for high-frequency switching applications requiring low conduction loss and fast recovery. Its 35 ns t_rr and 70 pF junction capacitance per diode support operation up to several hundred kHz in SMPS topologies.

Thermally, it delivers 2 °C/W junction-to-case resistance and operates from –55°C to +150°C, enabling reliable performance in automotive-grade and industrial power supplies where thermal cycling and surge robustness are critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	100 V - maximum repetitive reverse voltage; defines safe blocking capability in 100 V bus applications
I_F	10 A - continuous forward current rating; supports sustained 10 A conduction without derating at T_C ≤ 110°C
I_FSM	125 A - non-repetitive surge current (8.3 ms half-sine); withstands startup/inrush transients in DC-DC stages
t_rr	35 ns - reverse recovery time; enables efficient operation in 200–500 kHz switching converters
V_F	0.975 V @ 5 A, 25°C - low conduction loss; reduces power dissipation vs. standard FRDs in high-duty-cycle designs
C_J	70 pF @ 1 MHz, 4 V - junction capacitance per diode; impacts EMI and snubber design in hard-switched topologies
R_θJC	2 °C/W - thermal resistance; allows direct heatsinking to PCB copper or external heatsink for 10 A thermal management

Pinout & Package

TO-263AB (D2PAK) package with three terminals: Anode 1, Anode 2, and Cathode (common). Case is electrically connected to cathode. Matte tin-plated leads meet J-STD-002 solderability and JESD201 Class 2 whisker resistance.

Pin/Terminal	Circuit Role	Design Meaning
Anode 1	Input terminal for first diode	Accepts input from primary-side switch node in dual-output or interleaved rectification
Anode 2	Input terminal for second diode	Enables independent sourcing from two AC phases or split-rail inputs
Cathode	Common output node	Provides single-point DC output connection; electrically tied to exposed tab for thermal conduction

Key Features

Feature	Design Value
Dual-die common-cathode configuration	Reduces component count in dual-input or center-tapped secondary rectification without external parallel wiring
35 ns reverse recovery time	Minimizes switching losses and diode-induced ringing in 200+ kHz synchronous or quasi-resonant converters
0.975 V forward voltage @ 5 A	Lowers conduction loss by ~15% vs. comparable 100 V FRDs, improving full-load efficiency in 12–48 V output supplies
125 A surge rating (8.3 ms)	Survives repeated cold-start surges in telecom and server PSUs without degradation or bond-wire fusing
Moisture sensitivity level 1	Eliminates bake requirements before reflow; compatible with standard SMT assembly lines without special handling

Equivalent & Alternatives

The following parts are listed as comparable options for similar super fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH10R06DJF	10 A, 600 V, t_rr = 30 ns, VF = 1.15 V @ 5 A, TO-263AB	Higher V_RRM but higher V_F; better for 400–600 V systems, less efficient at 100 V bus	Select when system requires ≥400 V blocking and can accept higher conduction loss
MBR10100CT	10 A, 100 V, Schottky, V_F = 0.75 V @ 5 A, t_rr = N/A, TO-220AB	Lower V_F but no reverse recovery; TO-220AB limits board-level thermal performance vs. D2PAK	Select for ultra-low-loss 100 V applications where leakage >1 µA is acceptable and TO-220 layout fits

Compared with STTH10R06DJF and MBR10100CT, the SFS1002G offers optimal balance of 100 V blocking, 35 ns recovery, and D2PAK thermal capability-making it preferred for space-constrained, high-frequency 48–100 V industrial and telecom power supplies.

FAQ

What is the maximum junction temperature rating for the SFS1002G?

The SFS1002G has a maximum junction temperature (T_J) of +150°C and a minimum of –55°C. This rating enables operation in harsh environments such as industrial motor drives and telecom rectifiers. Thermal design must maintain junction temperature below this limit using the specified R_θJC = 2 °C/W and appropriate heatsinking. The SFS1002G datasheet confirms this absolute maximum under steady-state and transient conditions.

Is the SFS1002G pin-compatible with other devices in the SFS100xG family?

Yes, all SFS100xG devices-including SFS1002G-share identical TO-263AB (D2PAK) package, pinout, and thermal footprint. Only V_RRM (100 V for SFS1002G), V_F, and C_J differ across the family. This allows drop-in voltage-scaling during design validation or BOM optimization without layout changes.

Does the SFS1002G have a common-cathode or common-anode configuration?

The SFS1002G uses a common-cathode configuration with two anodes and one shared cathode terminal. This is confirmed in the device marking diagram and mechanical outline, where the exposed tab is electrically connected to the cathode. It supports dual-input rectification or parallel anode routing while maintaining single-point DC output.

What is the reverse leakage current specification for the SFS1002G at elevated temperature?

At T_J = 125°C and rated V_R, the SFS1002G exhibits a maximum reverse leakage current (I_R) of 200 µA per diode. At 25°C, leakage is ≤1 µA. This low leakage supports stable operation in high-temperature power supplies where thermal runaway or standby loss must be minimized.

Can the SFS1002G be used in surface-mount reflow processes without moisture preconditioning?

Yes-the SFS1002G is rated Moisture Sensitivity Level 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH and placed directly into standard lead-free reflow profiles without baking. This eliminates pre-reflow dry storage or bake steps, reducing manufacturing cost and cycle time for high-volume SMT lines.
