Product details
Overview
SFA1007G from Taiwan Semiconductor is a single-die super fast rectifier in TO-220AC package, rated for 10 A average forward current, 500 V repetitive peak reverse voltage (VRRM), and 125 A non-repetitive surge current (IFSM), used in high-efficiency DC-DC converters and switching inverters.
For engineers reviewing the SFA1007G datasheet, SFA1007G pinout, SFA1007G application, or SFA1007G equivalent, key selection criteria include its 1.700 V forward voltage at 10 A/25°C, 35 ns reverse recovery time, 50 pF junction capacitance, 3.5 °C/W junction-to-case thermal resistance, and AEC-Q101 qualification availability (SFA1007GH variant).
Technical Context
The SFA1007G is a silicon planar epitaxial super fast recovery rectifier optimized for high-frequency switching applications. Its 500 V VRRM rating and 35 ns trr support efficient operation in SMPS topologies where rapid turn-off minimizes switching losses.
Thermal performance is defined by a 3.5 °C/W RθJC, enabling reliable 10 A conduction at TJ ≤ 150°C with appropriate heatsinking. The device exhibits 10 µA max reverse leakage at 25°C and 400 µA at 100°C under rated VR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 500 V - maximum repetitive reverse blocking voltage; defines usable input voltage range in boost/buck converters |
| IF(AV) | 10 A - continuous forward current rating; determines heatsink sizing and PCB copper area requirements |
| IFSM | 125 A - 8.3 ms half-sine surge capability; supports inrush and fault-current handling without failure |
| VF @ 10A/25°C | 1.700 V - forward conduction loss at rated current; directly impacts power stage efficiency and thermal design |
| trr | 35 ns - reverse recovery time; enables stable operation up to ~3 MHz switching frequencies |
| CJ @ 1MHz/4V | 50 pF - junction capacitance; affects EMI generation and snubber design in high-dV/dt circuits |
| RθJC | 3.5 °C/W - thermal resistance from junction to case; sets minimum heatsink thermal resistance for safe operation |
Pinout & Package
Package: TO-220AC - 3-lead, single-ended through-hole package with isolated tab (cathode-connected); matte tin-plated leads compliant with J-STD-002; UL 94V-0 molding compound; 1.80 g typical weight; mounting torque ≤ 0.56 N·m.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward conduction | Connected to lower-potential side of load or switch node; requires low-inductance layout for fast recovery |
| Cathode | Output terminal for forward conduction; electrically tied to metal tab | Tab must be electrically isolated from heatsink unless circuit ground reference permits; dictates mounting insulation requirements |

|---|---|---|---|
| STTH10R06DJF | 600 V VRRM, 1.65 V VF @ 10 A, 30 ns trr, TO-220AC package | Higher voltage rating suits 600 V bus designs; slightly faster recovery but higher VF than SFA1007G at 500 V use point | Select when 600 V blocking margin is required or when 30 ns trr is critical for >1 MHz operation |
| VS-10EWH06-M3 | 600 V VRRM, 1.75 V VF @ 10 A, 35 ns trr, TO-220AC, AEC-Q101 qualified | Same trr and thermal resistance; 0.05 V higher VF; identical automotive qualification scope | Prefer when AEC-Q101 compliance is mandatory and 600 V rating provides system-level margin |

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for the SFA1007G?
The SFA1007G has a VRRM rating of 500 V, meaning it can reliably block up to 500 V in reverse bias without breakdown under repetitive conditions. This value is fixed per the part number suffix '007' and is confirmed in the absolute maximum ratings table of the official TSC datasheet K2103.
Does the SFA1007G have AEC-Q101 qualification?
The base SFA1007G is not AEC-Q101 qualified; however, the variant SFA1007GH is explicitly qualified per AEC-Q101. The 'H' suffix denotes automotive qualification, including stress testing for temperature cycling, humidity, and mechanical shock - verified in TSC's ordering information and version K2103 documentation.
What is the forward voltage (VF) of the SFA1007G at 10 A and 25°C?
The SFA1007G exhibits a maximum forward voltage of 1.700 V at 10 A forward current and 25°C junction temperature, as specified in the electrical characteristics table of the TSC datasheet. This value is measured under pulsed conditions (PW = 0.3 ms) and defines conduction loss at rated current.
What package type does the SFA1007G use, and is the tab electrically isolated?
The SFA1007G uses the TO-220AC package with a non-isolated metal tab connected internally to the cathode. The tab serves as both the cathode terminal and primary thermal path; therefore, electrical isolation from the heatsink is required unless the cathode is referenced to system ground.
How does the SFA1007G compare to the SFA1006G in terms of voltage rating and forward voltage?
The SFA1007G is rated for 500 V VRRM and has a VF of 1.700 V at 10 A/25°C, while the SFA1006G is rated for 400 V VRRM and 1.300 V VF under identical conditions. The higher voltage rating of the SFA1007G trades off slightly higher conduction loss for improved blocking margin in 400–500 V bus applications.
