Product details
Overview
SFA1004G from Taiwan Semiconductor is a 10A, 200V super fast rectifier diode in TO-220AC package, featuring 35ns reverse recovery time, 0.975V forward voltage at 10A/25°C, and 3.5°C/W junction-to-case thermal resistance-used in DC-DC converters and switching inverters for high-efficiency power conversion.
For engineers reviewing the SFA1004G datasheet, SFA1004G pinout, SFA1004G application, or SFA1004G equivalent, key selection criteria include VRRM = 200V, IF = 10A, trr = 35ns, VF ≤ 0.975V, and RθJC = 3.5°C/W for thermal design and switching loss optimization.
Technical Context
The SFA1004G employs a single-die planar epitaxial structure optimized for fast soft recovery, enabling low EMI and reduced switching losses in high-frequency SMPS. Its 200V VRRM rating and 125A IFSM support robust surge handling in transient-prone power rails.
Designed for operation up to 150°C junction temperature, the device delivers stable forward conduction and sub-10µA reverse leakage at 25°C (≤400µA at 100°C), with 70pF junction capacitance at 4V reverse bias-critical for snubberless flyback and freewheeling topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage; defines usable input voltage range in buck/boost stages |
| IF | 10 A - Continuous forward current rating; sets minimum heatsink requirement at 3.5°C/W RθJC |
| trr | 35 ns - Reverse recovery time; enables >100 kHz switching without excessive turn-off loss or ringing |
| VF | ≤0.975 V @ 10A, 25°C - Low conduction loss; contributes <9.75W dissipation per device at full load |
| CJ | 70 pF @ 4V - Junction capacitance; impacts snubber sizing and EMI filter design in high-dv/dt circuits |
| IFSM | 125 A - Non-repetitive surge current; withstands inrush and fault currents in 60Hz line-synchronized designs |
Pinout & Package
TO-220AC package: single-ended anode-cathode configuration with isolated metal tab (cathode-connected), matte tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, and 1.80g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry | Connected to input/source side; requires trace width ≥1.5mm for 10A continuous routing |
| Cathode (Lead 2) | Forward current exit / case connection | Electrically tied to metal tab; must be isolated from heatsink unless cathode-referenced layout |
| Tab (Case) | Thermal path + Cathode terminal | Primary heat dissipation surface; mounting torque ≤0.56 N·m to avoid die cracking |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery | 35 ns trr enables high-frequency operation with minimal switching loss and EMI generation |
| Low forward voltage | 0.975 V max at 10A reduces conduction loss by ~15% vs. standard FRDs in 200V class |
| High surge capability | 125 A IFSM supports 10× rated current for 8.3ms, critical for AC line startup and motor drive faults |
| Thermal performance | 3.5°C/W RθJC allows 7.1W dissipation at ΔT = 25°C case rise-enabling compact heatsink use |
Applications
| DC-DC Converter Output Rectification | Switching Inverter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in isolated 48V–200V output DC-DC converters operating at 100–500 kHz. IC Role / Device Role / Timing Role: Power diode conducting during transformer secondary voltage polarity, recovering before next switching cycle. Use Value: 35 ns trr and 0.975 V VF minimize conduction + switching losses, improving efficiency by ≥1.2% over standard FRDs. | Use Scenario: Freewheeling path across inductive loads (e.g., motor windings, solenoids) in half-bridge inverters. IC Role / Device Role / Timing Role: Provides low-loss return path when high-side switch turns off; recovers before low-side switch commutation. Use Value: Fast soft recovery suppresses voltage spikes >200V, reducing snubber size and gate driver stress in 200V bus systems. |
| Industrial SMPS Input Stage | UPS Battery Charging Circuit |
Use Scenario: Input bridge rectification in 200V-rated industrial switch-mode power supplies with PFC front-end. IC Role / Device Role / Timing Role: Handles 10A average input current with 125A surge tolerance during AC line transients.

IC Role / Device Role / Timing Role: Synchronous rectifier replacement in non-isolated charger output stage, conducting during low-side MOSFET on-time. Use Value: 70pF CJ limits capacitive turn-on loss; low VF maintains >94% efficiency at 10A charge current. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R02DJF | VRRM = 200V, trr = 30ns, VF = 0.92V @ 10A, TO-220AC, but higher cost and no AEC-Q101 option | Better trr and VF, yet lacks automotive qualification variant | Select when lowest switching loss is prioritized over qualification or cost sensitivity |
| ON Semiconductor MUR1020CT | Dual common-cathode configuration (2×10A), VRRM = 200V, trr = 35ns, VF = 0.97V, TO-220AB package with different pinout | Requires PCB redesign due to dual-diode layout and non-identical lead spacing | Choose only if dual-diode topology is needed; not a drop-in replacement for SFA1004G |
Compared with STTH10R02DJF and MUR1020CT, the SFA1004G offers balanced performance at lower cost and AEC-Q101 availability, while maintaining identical TO-220AC footprint and thermal metrics-making it optimal for cost-sensitive industrial and automotive auxiliary power designs.

FAQ
What is the maximum junction temperature rating for the SFA1004G?
The SFA1004G has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings in the official datasheet. This rating allows reliable operation in enclosed industrial enclosures or under forced-air cooling with case temperatures up to 125°C, provided thermal design maintains junction rise within limit. The SFA1004G must not exceed this value during steady-state or transient conditions.
Is the SFA1004G AEC-Q101 qualified?
The base SFA1004G is not AEC-Q101 qualified; however, the variant SFA1004GH (with 'H' suffix) meets AEC-Q101 stress test requirements for automotive under-hood applications. Always verify ordering code suffix-only SFA1004GH carries the qualification. The SFA1004G itself remains suitable for industrial and commercial power systems where automotive qualification is not mandated.
What is the reverse recovery time (trr) of the SFA1004G and under what test conditions?
The SFA1004G has a typical reverse recovery time (trr) of 35 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the manufacturer's electrical specifications table. This value is confirmed across production lots and applies at TA = 25°C. The SFA1004G maintains consistent trr performance up to TJ = 125°C, supporting stable high-frequency operation in demanding SMPS designs.
Does the SFA1004G have a built-in thermal protection feature?
No, the SFA1004G is a passive silicon rectifier diode and does not include thermal shutdown, sensing, or protection circuitry. Thermal management relies entirely on external design-such as heatsinking, airflow, and PCB copper area-to keep junction temperature below 150°C. The SFA1004G's 3.5°C/W RθJC and 1.80g mass are provided to enable accurate thermal modeling, but no internal protection mechanism exists.
Can the SFA1004G replace a standard FR107 diode in a 200V application?
The SFA1004G can replace FR107 in 200V applications only if forward current demand is ≤10A and layout accommodates TO-220AC mechanical dimensions. While both share 200V VRRM, the SFA1004G offers superior trr (35 ns vs. ~500 ns for FR107) and lower VF (0.975 V vs. ~1.1 V), significantly reducing switching loss-but requires verifying heatsink compatibility and surge margin, as FR107 lacks specified IFSM.
