Product details
Overview
SFA1001G from Taiwan Semiconductor is a 10A, 50V repetitive peak reverse voltage super fast rectifier diode in TO-220AC package, featuring 0.975V forward voltage at 10A and 25°C, 35ns reverse recovery time, and 3.5°C/W junction-to-case thermal resistance-used in DC-DC converters and freewheeling paths where low conduction loss and fast switching are required.
For engineers reviewing the SFA1001G datasheet, SFA1001G pinout, SFA1001G application, or SFA1001G equivalent, key selection criteria include its 50V VRRM, 125A IFSM, AEC-Q101 qualification availability (SFA1001GH), TO-220AC mechanical compatibility, and verified 35ns trr performance under IF = 0.5A / IR = 1.0A test conditions.
Technical Context
The SFA1001G is a single-die, unidirectional super fast recovery rectifier optimized for high-frequency switching applications. Its 35ns reverse recovery time and 70pF junction capacitance at 1MHz/4V support efficient operation in SMPS operating up to several hundred kHz.
Thermally, it delivers 3.5°C/W junction-to-case resistance with a 150°C maximum junction temperature, enabling 10A continuous forward current derating above 25°C ambient-validated per JEDEC JESD201 Class 2 whisker testing and UL 94V-0 molding compound compliance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage; defines safe DC/peak AC voltage limit in freewheeling or output rectification |
| IF | 10 A - Continuous average forward current at case temperature ≤ 75°C; sets baseline conduction capability |
| IFSM | 125 A - Non-repetitive surge current (8.3ms half-sine); supports inrush and transient overload tolerance |
| VF | 0.975 V @ 10A, 25°C - Low forward drop reduces conduction loss and thermal stress in high-current paths |
| trr | 35 ns - Measured at IF = 0.5A, IR = 1.0A, Irr = 0.25A; enables high-frequency switching with minimal reverse recovery loss |
| RθJC | 3.5 °C/W - Junction-to-case thermal resistance; determines heatsink sizing requirement for thermal management |
| CJ | 70 pF @ 1MHz, 4V - Junction capacitance impacts high-frequency noise and snubber design in switching nodes |
Pinout & Package
Package: TO-220AC - 3-lead, single-ended vertical mounting package with center tab (cathode) electrically connected to lead 2; matte tin-plated leads compliant with J-STD-002 solderability; 0.56 N·m max mounting torque; polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Lead 1 (Anode) | Anode connection | Input terminal for forward conduction; isolated from case; requires PCB trace routing for high-current paths |
| Lead 2 (Cathode) | Cathode connection & heat sink interface | Electrically tied to metal tab; serves as primary thermal path and circuit return; must be insulated if mounted to grounded heatsink |
| Lead 3 (Anode) | Second anode terminal | Dual-anode configuration for parallel current sharing or dual-source input; not internally connected to Lead 1 |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery (trr = 35 ns) | Enables efficient operation in 100–500 kHz SMPS topologies with minimized reverse recovery loss and EMI |
| Low VF (0.975 V @ 10A) | Reduces power dissipation by ~1W vs. standard FRDs at same current, lowering thermal load on heatsink |
| TO-220AC package with RθJC = 3.5°C/W | Supports ≥8W steady-state power dissipation with 25°C case temperature rise, simplifying thermal design |
| AEC-Q101 qualification option (SFA1001GH) | Validated for automotive under-hood applications including engine control and ADAS power supplies |
| RoHS & halogen-free (IEC 61249-2-21) | Meets global environmental compliance requirements without compromising thermal or electrical performance |

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 | 600V VRRM, 10A IF, 30ns trr, TO-220AC, VF = 1.05V @ 10A | Higher voltage rating suits 400V+ systems; slightly higher VF increases conduction loss in 50V designs | Select when higher reverse voltage margin or faster trr is prioritized over minimal VF at 50V operation |
| ON Semiconductor MUR1050CT | 50V VRRM, 10A IF, 35ns trr, TO-220AB (dual common-cathode), VF = 0.92V @ 10A | Dual-diode configuration enables full-wave rectification; different pinout and thermal path vs. single-diode TO-220AC | Choose for dual-output or center-tapped transformer designs; verify mechanical fit and thermal interface compatibility |
Compared with STTH10R06DJF and MUR1050CT, the SFA1001G offers the lowest forward voltage (0.975V) among 50V-rated 10A super fast rectifiers in TO-220AC, optimizing conduction efficiency in low-voltage, high-current DC-DC stages-while maintaining identical trr and thermal resistance as MUR1050CT's single-diode equivalent.

FAQ
What is the maximum junction temperature rating for the SFA1001G?
The SFA1001G has a maximum junction temperature (TJMAX) of +150°C, validated across its full operating range from –55°C to +150°C storage temperature. This rating enables reliable operation in high-ambient environments such as enclosed industrial power modules or under-hood automotive locations when paired with appropriate heatsinking based on its 3.5°C/W RθJC.
Is the SFA1001G pin-compatible with other TO-220AC rectifiers like the 1N5408?
No-the SFA1001G uses a three-lead TO-220AC configuration with dual anodes and shared cathode (lead 2), whereas the 1N5408 is a two-lead DO-201AD device. Even among TO-220AC rectifiers, pinout varies by internal configuration; the SFA1001G's specific dual-anode layout requires verification against footprint and schematic symbol before substitution.
Does the SFA1001G meet automotive qualification standards?
The base SFA1001G is not AEC-Q101 qualified; however, the SFA1001GH variant-identical in all electrical and thermal specifications-is explicitly qualified to AEC-Q101 for automotive under-hood applications. Designers requiring automotive compliance must specify the "H" suffix ordering code to receive the tested and certified version.
What is the reverse recovery time test condition for the SFA1001G?
The SFA1001G reverse recovery time (trr) of 35ns is measured under standardized conditions: forward current IF = 0.5A, reverse current IR = 1.0A, reverse recovery current Irr = 0.25A, and specified test circuit per Figure 6 in the datasheet. This reflects real-world behavior in high-frequency switching nodes, not idealized or pulsed-only conditions.
How does the SFA1001G's forward voltage compare to similar 10A super fast rectifiers at 10A load?
At 10A and 25°C, the SFA1001G specifies a maximum forward voltage of 0.975V-lower than STTH10R06DJF (1.05V) and comparable to ON Semiconductor's MUR1050CT (0.92V). This 5–10% reduction versus common alternatives directly lowers conduction loss and thermal stress in 12V–48V DC-DC output stages where the SFA1001G is typically deployed.
