Product details
Overview
SFA1002GHC0G from Taiwan Semiconductor is a 10A, 100V super fast rectifier diode in TO-220AC package, optimized for high-efficiency DC-DC conversion with 0.975V forward voltage at 10A and 25°C, 35ns reverse recovery time, and 125A surge capability. It serves as a freewheeling or output rectifier in switching power supplies.
For engineers reviewing the SFA1002GHC0G datasheet, SFA1002GHC0G pinout, SFA1002GHC0G application, or SFA1002GHC0G equivalent, key selection criteria include VRRM = 100V, IF = 10A, trr = 35ns, RθJC = 3.5°C/W, and AEC-Q101 qualification status - critical for automotive-grade power conversion designs.
Technical Context
This super fast rectifier uses a single-die silicon PN junction structure with optimized carrier lifetime control to achieve 35ns reverse recovery time while maintaining low forward voltage (0.975V @ 10A, 25°C) and high surge robustness (IFSM = 125A, 8.3ms half-sine). Its thermal resistance of 3.5°C/W enables reliable operation up to 150°C junction temperature.
The device is rated for repetitive peak reverse voltage of 100V (VRRM) and RMS reverse voltage of 70V (VR(RMS)), with leakage current ≤10µA at 25°C and ≤400µA at 100°C. Junction capacitance is 70pF at 1MHz/4V, supporting high-frequency switching performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum blocking voltage in reverse bias; defines usable input/output voltage range in buck, flyback, or freewheeling topologies |
| IF | 10 A - Continuous forward current rating; determines heatsink sizing and conduction loss budget at full load |
| trr | 35 ns - Reverse recovery time; enables efficient operation at >100 kHz switching frequencies with reduced switching loss |
| VF | 0.975 V @ 10A, 25°C - Forward voltage drop; directly sets conduction loss (Pcond ≈ IF × VF) and thermal design margin |
| RθJC | 3.5 °C/W - Junction-to-case thermal resistance; enables accurate case temperature prediction under 10A load for mechanical mounting design |
| IFSM | 125 A - Non-repetitive surge current; supports startup, overload, and transient fault conditions without failure |
| Junction Temp | -55°C to +150°C - Operating temperature range; validates suitability for under-hood automotive environments |
Pinout & Package
Package: TO-220AC - 3-lead through-hole package with isolated tab (cathode-connected tab), matte tin-plated leads, UL 94V-0 molding compound, and 0.56 N·m maximum mounting torque.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); requires PCB trace capable of 10A continuous current |
| Cathode | Forward current exit / reverse blocking terminal | Electrically tied to metal tab; must be electrically isolated from heatsink unless cathode-referenced layout is used |
| Tab (Case) | Cathode connection | Provides primary thermal path to heatsink; isolation washer required if heatsink is not at cathode potential |
Key Features

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 | VRRM = 600V, VF = 1.7V @ 10A, trr = 30ns, TO-220AC | Higher voltage rating but higher forward drop; suited for universal-input PFC front-ends, not 100V-output stages | Select when >400V blocking is required; avoid where low VF dominates efficiency targets |
| ONsemi MUR10100CT | Dual common-cathode configuration, VRRM = 100V, VF = 1.2V @ 10A, trr = 50ns, TO-220AB | Two diodes in one package; higher VF and slower recovery than SFA1002GHC0G; non-AEC-Q101 | Use only in cost-sensitive dual-path designs where AEC-Q101 is not mandated |

FAQ
What is the peak repetitive reverse voltage rating for SFA1002GHC0G?
The SFA1002GHC0G has a peak repetitive reverse voltage (VRRM) rating of 100 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version K2103), and defines the maximum reverse-bias voltage the device can block continuously without breakdown. It is not interchangeable with higher-voltage variants like SFA1003G (150V) or SFA1004G (200V).
Is SFA1002GHC0G AEC-Q101 qualified?
Yes, SFA1002GHC0G is AEC-Q101 qualified. The "H" suffix in the ordering code explicitly denotes AEC-Q101 qualification, and the datasheet confirms this under FEATURES and ORDERING INFORMATION sections. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing - validating its use in automotive power electronics.
What is the forward voltage of SFA1002GHC0G at 10A and 25°C?
The forward voltage (VF) of SFA1002GHC0G is 0.975 V at IF = 10 A and TJ = 25°C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and represents the typical conduction loss under nominal load - critical for calculating thermal rise and system efficiency in DC-DC designs.
Does SFA1002GHC0G have a cathode-connected tab?
Yes, SFA1002GHC0G uses a TO-220AC package with the cathode electrically connected to the metal tab. This is confirmed in the Mechanical Data section and Marking Diagram of the datasheet. Designers must ensure electrical isolation between the tab and heatsink unless the heatsink is referenced to the cathode potential - otherwise, short circuits may occur.
What is the junction-to-case thermal resistance of SFA1002GHC0G?
The junction-to-case thermal resistance (RθJC) of SFA1002GHC0G is 3.5°C/W, as published in the Thermal Performance section of the datasheet. This parameter enables accurate prediction of case temperature rise under 10A DC load and informs heatsink selection and mounting interface design - especially important in sealed or high-ambient-temperature automotive applications.
