Product details
Overview
SFAF1006G from Taiwan Semiconductor is a 10 A, 400 V repetitive peak reverse voltage (VRRM) super fast rectifier diode in ITO-220AC package, featuring 1.300 V forward voltage at 10 A and 25°C, 35 ns reverse recovery time, and AEC-Q101 qualification option. It serves as a high-efficiency freewheeling or output rectifier in automotive DC-DC converters.
For engineers reviewing the SFAF1006G datasheet, SFAF1006G pinout, SFAF1006G application, or SFAF1006G equivalent, key selection factors include its 400 V VRRM, 150 A surge capability, 4 °C/W junction-to-case thermal resistance, glass-passivated junction, and UL recognition (E-326243) for safety-critical power conversion designs.
Technical Context
The SFAF1006G employs a single-die silicon PN junction with glass passivation to ensure stable operation under high dv/dt and thermal stress. Its 35 ns trr enables use in high-frequency switching topologies up to several hundred kHz without excessive switching losses.
Designed for surface-mount-compatible through-hole mounting on heatsinks, the device delivers 10 A average forward current with derating above 25°C case temperature and supports 150 A non-repetitive surge (8.3 ms half-sine), making it suitable for transient-heavy industrial and automotive power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse blocking voltage; defines usable input/output voltage range in flyback or buck-derived topologies |
| IF | 10 A - Continuous average forward current at TC = 25°C; requires heatsinking above ambient to maintain reliability |
| IFSM | 150 A - Peak non-repetitive surge current; withstands inrush and fault transients in motor drives and SMPS |
| VF | 1.300 V @ 10 A, 25°C - Low conduction loss improves efficiency in high-current output stages |
| trr | 35 ns - Fast recovery minimizes reverse recovery charge (Qrr) and associated switching losses |
| RθJC | 4 °C/W - Enables predictable thermal design when mounted to heatsink with proper torque (≤0.56 N·m) |
| Junction temp | –55 to +150°C - Supports operation in under-hood automotive environments and industrial enclosures |
Pinout & Package
Package: ITO-220AC - 3-terminal, isolated tab, matte tin-plated leads compliant with J-STD-002 solderability; UL 94V-0 molding compound; polarity marked on device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry | Connected to lower-potential side of circuit; must be routed with low-inductance path in high-dI/dt applications |
| Cathode (Lead 2) | Forward current exit / reverse blocking terminal | Typically tied to output rail or switching node; polarity marking on package confirms cathode orientation |
| Tab (Case) | Electrically connected to cathode | Provides thermal path to heatsink; electrically isolated mounting required if cathode is not at chassis ground |

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 | 400 V VRRM, 10 A IF, 30 ns trr, TO-220AC package, no AEC-Q101 option | Lower trr but lacks automotive qualification and UL recognition | Preferred where ultra-fast recovery dominates over safety certification |

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the SFAF1006G?
The SFAF1006G has a VRRM of 400 V, as confirmed in the Absolute Maximum Ratings table of the official datasheet (Version H2105). This rating defines the highest reverse voltage the device can block repeatedly without breakdown and is validated across the full operating temperature range.
Is the SFAF1006G AEC-Q101 qualified?
The base SFAF1006G is not AEC-Q101 qualified, but the variant SFAF1006GH is explicitly listed as AEC-Q101 qualified in the Ordering Information section. Both share identical electrical and thermal specifications; only the 'H' suffix denotes qualification testing per AEC-Q101 stress requirements.
What is the forward voltage (VF) of the SFAF1006G at rated current?
The SFAF1006G exhibits a maximum forward voltage of 1.300 V at 10 A forward current and 25°C junction temperature, per the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects.
Does the SFAF1006G have UL recognition?
Yes, the SFAF1006G is UL Recognized under File # E-326243, as stated in the FEATURES section. This applies to the entire SFAF1001G–SFAF1008G family and covers flammability (UL 94V-0), construction, and electrical safety compliance.
What is the thermal resistance from junction to case (RθJC) for the SFAF1006G?
The SFAF1006G has a typical junction-to-case thermal resistance of 4 °C/W, specified in the THERMAL PERFORMANCE section. This value assumes proper mounting with ≤0.56 N·m torque onto a flat, clean heatsink surface using the ITO-220AC package tab.
