Product details
Overview
SF1003G from Taiwan Semiconductor is a 150 V, 10 A super fast recovery rectifier diode in TO-220AB package, featuring 35 ns reverse recovery time, 0.975 V forward voltage at 5 A and 25°C, and 70 pF junction capacitance - used in freewheeling paths and DC/DC converter output stages.
For engineers reviewing the SF1003G datasheet, SF1003G pinout, SF1003G application, or SF1003G equivalent, key selection criteria include repetitive peak reverse voltage (150 V), surge current rating (125 A), thermal resistance (3.5 °C/W), AEC-Q101 qualification availability, and TO-220AB mechanical compatibility with heatsink mounting.
Technical Context
This device is a single-die, dual-terminal silicon rectifier optimized for high-frequency switching applications where low conduction loss and fast turn-off are critical. Its 35 ns trr and 0.975 V VF at 5 A enable efficient operation in 100–500 kHz SMPS topologies.
The TO-220AB package provides direct case-to-heatsink thermal path with RθJC = 3.5 °C/W, supporting continuous 10 A operation up to 150°C junction temperature. Polarity is marked on the device body per standard diode convention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/freewheeling clamp circuits |
| IF | 10 A - average forward current rating at TC = 100°C; determines continuous power handling with heatsink |
| IFSM | 125 A - non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current tolerance |
| trr | 35 ns - reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables high-frequency switching with low switching loss |
| VF | 0.975 V - forward voltage drop per diode at IF = 5 A, TJ = 25°C; directly impacts conduction loss and thermal design |
| CJ | 70 pF - junction capacitance at 1 MHz, VR = 4.0 V; affects high-frequency noise and snubber sizing |
Pinout & Package
TO-220AB package: 3-lead outline with center tab (cathode) electrically connected to pin 2; anode (pin 1) and cathode (pin 2) are functional terminals; pin 3 is unused internal tie to tab. Mounting torque ≤ 0.56 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Input terminal for forward conduction; connects to switching node or inductor output in freewheeling configuration |
| Pin 2 / Tab | Cathode | Output terminal; electrically tied to metal tab for direct heatsink mounting and low-inductance return path |
| Pin 3 | Internal tie to tab | No external connection required; serves mechanical reinforcement and thermal coupling to case |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery | 35 ns trr enables use in ≥200 kHz converters without excessive switching loss or EMI |
| Low forward voltage | 0.975 V at 5 A reduces conduction loss by ~15% vs. standard fast rectifiers in same package |
| High surge capability | 125 A IFSM supports robustness against load dump and startup transients in automotive-grade designs |
| TO-220AB thermal performance | RθJC = 3.5 °C/W allows 10 A continuous operation with modest heatsinking at TC ≤ 100°C |
Applications

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 | 600 V VRRM, 35 ns trr, 1.15 V VF @ 5 A - higher voltage rating but higher forward drop | Used in higher bus voltage systems (e.g., 400 V PFC outputs); less optimal for 150 V-class designs due to excess voltage margin and higher conduction loss | Select when system requires >300 V blocking or legacy STMicro design continuity; verify thermal derating at 10 A |
| ON Semi MUR1060CT | Dual common-cathode configuration, 600 V VRRM, 60 ns trr, 1.7 V VF @ 5 A - slower recovery and higher VF than SF1003G | Common in cost-sensitive industrial supplies; not suitable for high-frequency or low-loss designs requiring <40 ns trr | Acceptable only if layout allows larger heatsink and efficiency targets permit ≥1.5% higher conduction loss |
Compared with STTH10R06DJF and MUR1060CT, the SF1003G delivers optimal balance of 150 V rating, 35 ns speed, and 0.975 V forward drop - making it preferred for compact, high-efficiency 100–200 V DC/DC and inverter freewheeling where voltage margin and thermal headroom are tightly constrained.

FAQ
What is the maximum junction temperature rating for SF1003G?
The SF1003G has a maximum junction temperature (TJ) rating of +150°C, with operational range from –55°C to +150°C. This rating is maintained under specified thermal conditions including RθJC = 3.5 °C/W and proper heatsink mounting. Derating curves in the SF1003G datasheet define allowable forward current versus case temperature, ensuring safe operation within this limit.
Is SF1003G pin-compatible with other devices in the SF100xG family?
Yes, all SF100xG devices - including SF1001G through SF1008G - share identical TO-220AB package dimensions, pinout, and terminal assignments. The SF1003G uses the same anode (pin 1), cathode/tab (pin 2), and internal tie (pin 3) configuration as other members, enabling direct substitution based on required VRRM without PCB changes.
Does SF1003G meet AEC-Q101 qualification?
The SF1003G is available in an AEC-Q101 qualified version designated SF1003GH. Standard SF1003G is not AEC-Q101 qualified; only units ordered with the "H" suffix undergo full stress testing per AEC-Q101 Rev D. Automotive designs requiring qualification must specify SF1003GH and verify compliance documentation from Taiwan Semiconductor.
What is the reverse recovery time test condition for SF1003G?
The SF1003G reverse recovery time (trr) is measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per JEDEC JESD24-11. This standardized condition ensures consistent comparison across fast rectifiers. The typical value is 35 ns, with no maximum specified - confirming guaranteed performance at or below this value under the defined test setup.
How does SF1003G junction capacitance affect high-frequency design?
The SF1003G exhibits 70 pF junction capacitance (CJ) at 1 MHz and 4.0 V reverse bias. This value influences snubber network sizing, EMI filter design, and switching node ringing in topologies above 100 kHz. Lower CJ compared to general-purpose rectifiers reduces capacitive coupling and improves hard-switching efficiency - a key advantage in compact DC/DC converters using the SF1003G.
