Product details
Overview
SFF1006GA from Taiwan Semiconductor is a 10A, 400V repetitive peak reverse voltage super fast rectifier diode in ITO-220AB package, featuring 35ns reverse recovery time, 1.300V max forward voltage at 5A/25°C, and 8°C/W junction-to-case thermal resistance-used in high-efficiency DC-DC converters and switching inverters.
For engineers reviewing the SFF1006GA datasheet, SFF1006GA pinout, SFF1006GA application, or SFF1006GA equivalent, key selection criteria include its 400V VRRM, dual-die configuration, AEC-Q101 qualification option (SFF1006GAH), UL recognition (E-326243), and suitability for freewheeling and snubber circuits requiring low trr and low VF.
Technical Context
The SFF1006GA is a single-phase, dual-die super fast recovery rectifier optimized for high-frequency switching applications. It delivers 10A average forward current with 125A non-repetitive surge capability and operates across -55°C to +150°C junction temperature range.
Its 35ns reverse recovery time and 50pF junction capacitance per diode support efficient operation in 50–500kHz SMPS topologies. The device uses matte tin-plated leads compliant with J-STD-002 and meets JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/clamp circuits |
| IF | 10 A - continuous average forward current at case temperature ≤75°C; determines heatsink sizing |
| IFSM | 125 A - 8.3ms half-sine surge rating; supports inrush and fault-current handling |
| trr | 35 ns - measured at IF=0.5A, IR=1.0A, Irr=0.25A; enables high-frequency switching with low switching loss |
| VF | 1.300 V max at 5A, 25°C - forward voltage drop directly impacts conduction loss and thermal design |
| RθJC | 8 °C/W - thermal resistance from junction to case; used to calculate ΔTJ = Ploss × RθJC |
| CJ | 50 pF per diode at 1MHz, 4V - low capacitance minimizes capacitive coupling and EMI in high-dv/dt environments |
Pinout & Package
Package: ITO-220AB - insulated TO-220 variant with internal isolation between collector (cathode) and mounting tab; 3-terminal through-hole package rated for 0.56 N·m mounting torque; UL 94V-0 molding compound; polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input current entry point | Connected to source/switch node in freewheeling path; must withstand full IF and IFSM |
| Cathode (Lead 2) | Output current exit point | Electrically tied to isolated metal tab; serves as high-side return in half-bridge configurations |
| Isolated Tab (Lead 3) | Thermal & mechanical anchor | Internally isolated from both anode and cathode; enables direct heatsinking without electrical shorting |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery | 35 ns trr enables operation up to 500 kHz with minimal switching loss and EMI |
| Dual-die construction | Two independent die in one package improve current sharing and thermal distribution vs. single-die alternatives |
| AEC-Q101 qualified option | SFF1006GAH variant available for automotive powertrain and ADAS subsystems requiring stress-tested reliability |
| UL Recognized | File #E-326243 confirms compliance with UL 60747-1 for discrete semiconductors in safety-critical systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH10R04DJF | 400V VRRM, 10A IF, 30ns trr, TO-220AC package (non-isolated tab) | Requires insulating washer for heatsink mounting; lacks UL recognition and AEC-Q101 option | Preferred where lowest trr is critical and isolation not needed |
| VS-10EWH04-M3 | 400V VRRM, 10A IF, 35ns trr, TO-247AC package; 1.25V VF @ 5A | Larger footprint and higher cost; better thermal performance (RθJC = 5.5°C/W) but no AEC-Q101 variant | Selected when higher power dissipation demands superior thermal management |
Compared with STTH10R04DJF and VS-10EWH04-M3, the SFF1006GA uniquely combines ITO-220AB's built-in isolation, UL recognition, and AEC-Q101 availability in a cost-optimized 10A/400V super fast rectifier-making it optimal for space-constrained, safety-certified, and automotive-qualified designs.

FAQ
What is the maximum junction temperature rating for the SFF1006GA?
The SFF1006GA has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings in the official datasheet. This rating allows operation in high-ambient industrial environments when paired with appropriate heatsinking. Derating curves confirm 10A IF is sustainable up to 75°C case temperature. Thermal design must account for RθJC = 8°C/W and actual power dissipation calculated from VF and IF.
Does the SFF1006GA have AEC-Q101 qualification?
The base SFF1006GA is not AEC-Q101 qualified, but the pin-compatible variant SFF1006GAH is explicitly qualified per AEC-Q101 Rev D for automotive applications. The "H" suffix denotes qualification, including stress testing for temperature cycling, humidity, and mechanical shock. Customers requiring automotive-grade reliability must specify SFF1006GAH-not SFF1006GA-when ordering.
What is the reverse recovery time (trr) test condition for the SFF1006GA?
The SFF1006GA reverse recovery time is specified as 35ns maximum under the conditions: IF = 0.5A, IR = 1.0A, Irr = 0.25A, with measurement performed at TA = 25°C. This test method follows JEDEC standard JESD24-10 and is confirmed in the Electrical Specifications table on page 2 of the SFF1001GA–SFF1008GA datasheet (Version E2105).
How does the ITO-220AB package differ from standard TO-220AB in the SFF1006GA?
The ITO-220AB package used by the SFF1006GA features internal electrical isolation between the metal tab and both anode and cathode terminals-unlike standard TO-220AB where the tab connects to the cathode. This allows direct mounting to a grounded heatsink without external insulation. The SFF1006GA's tab is electrically floating, enabling flexible layout in half-bridge and multi-rail systems.
What is the forward voltage (VF) specification for the SFF1006GA at rated current?
The SFF1006GA has a maximum forward voltage of 1.300V at IF = 5A and TJ = 25°C, as stated in the Electrical Specifications table. At full-rated 10A average current and elevated junction temperatures (e.g., 125°C), VF increases to approximately 1.45V. This value directly determines conduction loss (Pcond = IF × VF) and must be included in thermal modeling for the SFF1006GA.
