Product details
Overview
SFAF2006G from Taiwan Semiconductor is a 20 A, 400 V repetitive peak reverse voltage (VRRM) super fast rectifier diode in ITO-220AC package, featuring 1.300 V forward voltage at 20 A and 25°C, 35 ns reverse recovery time, and 150 pF junction capacitance - used in high-efficiency DC-DC converters and switching inverters.
For engineers reviewing the SFAF2006G datasheet, SFAF2006G pinout, SFAF2006G application, or SFAF2006G equivalent, key selection criteria include VRRM = 400 V, IF = 20 A, trr = 35 ns, RθJC = 3°C/W, and UL Recognized File # E-326243 compliance for industrial power conversion designs.
Technical Context
This super fast rectifier uses glass passivated chip junction technology to achieve low forward voltage and high surge current capability (IFSM = 200 A, 8.3 ms half-sine). Its 35 ns reverse recovery time enables operation in high-frequency switching topologies up to several hundred kHz.
The ITO-220AC package provides low thermal resistance (RθJC = 3°C/W) and matte tin-plated leads compliant with J-STD-002 solderability, supporting reliable through-hole mounting with 0.56 N·m maximum torque and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum non-repetitive reverse blocking voltage; defines usable input voltage range in buck/boost converters |
| IF | 20 A continuous - Rated average forward current at case temperature ≤ 100°C; determines heatsink sizing |
| trr | 35 ns - Measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables <500 kHz switching without excessive switching loss |
| VF | 1.300 V @ 20 A, 25°C - Directly impacts conduction loss and thermal design in high-current paths |
| CJ | 150 pF @ 1 MHz, 4.0 V - Limits high-frequency noise coupling and affects snubber design in hard-switched circuits |
| RθJC | 3°C/W - Junction-to-case thermal resistance; enables accurate thermal modeling when mounted on heatsink |
Pinout & Package
ITO-220AC package: single-die, 3-terminal through-hole device with anode (A), cathode (K), and metal tab (electrically connected to cathode). Tab serves as primary heat path and must be electrically isolated unless referenced to cathode potential.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry | Connected to input/high-side node; polarity marked on device body |
| Cathode (Lead 2) | Forward current exit | Connected to output/low-side node; electrically tied to metal tab |
| Metal tab | Cathode terminal & thermal path | Must be mounted to heatsink with electrically insulating thermal interface if cathode is not at chassis ground |
Key Features
| Feature | Design Value |
|---|---|

| UL Recognized (E-326243) | Validates flammability (UL 94V-0), creepage/clearance, and construction for end-equipment safety certification |
| AEC-Q101 qualified option (SFAF2006GH) | Supports automotive-grade stress testing including HTGB, HTRB, and temperature cycling for under-hood applications |
| Halogen-free (IEC 61249-2-21) | Meets environmental compliance requirements for RoHS-compliant manufacturing and end-of-life disposal |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2004TV | VRRM = 400 V, trr = 30 ns, VF = 1.25 V @ 20 A, same ITO-220AC package | Lower trr and VF reduce switching and conduction loss but require verification of gate drive interaction in synchronous rectified topologies | Preferred where <30 ns trr is critical; verify layout parasitics do not induce oscillation |
| IXYS MUR2040CT | Dual common-cathode configuration, VRRM = 400 V, trr = 35 ns, VF = 1.25 V @ 20 A per diode | Provides dual-diode integration for center-tapped or interleaved designs; requires PCB redesign for single-diode footprint | Select when dual-diode topology is needed; not drop-in compatible due to pinout and internal structure |
Compared with STTH2004TV and IXYS MUR2040CT, the SFAF2006G offers balanced trade-offs in cost, thermal performance (RθJC = 3°C/W), and qualification status (AEC-Q101 option available), making it suitable for cost-sensitive industrial and automotive auxiliary power supplies where single-diode simplicity is prioritized.

FAQ
What is the maximum junction temperature rating for the SFAF2006G?
The SFAF2006G has a maximum junction temperature (TJ) rating of +150°C, with operational storage temperature ranging from –55°C to +150°C. This allows use in high-ambient environments such as enclosed industrial enclosures or under-hood automotive locations when properly heatsinked. Thermal derating curves in the datasheet define safe IF limits above 25°C case temperature.
Is the SFAF2006G pin-compatible with other devices in the SFAF200xG family?
Yes, all SFAF200xG variants-including SFAF2006G-share identical ITO-220AC packaging, pinout, and mechanical dimensions. Only VRRM (400 V for SFAF2006G), VF, and CJ differ across the series. This enables direct substitution in existing layouts when voltage rating aligns with system requirements.
Does the SFAF2006G meet automotive qualification standards?
The base SFAF2006G is not AEC-Q101 qualified, but the variant SFAF2006GH is explicitly qualified per AEC-Q101. The GH version undergoes additional stress testing including high-temperature gate bias, high-temperature reverse bias, and temperature cycling, making it suitable for automotive body electronics and ADAS power modules.
What is the reverse leakage current specification for the SFAF2006G at elevated temperature?
At TJ = 125°C and rated VR, the SFAF2006G exhibits a maximum reverse leakage current (IR) of 400 µA. At 25°C, IR is limited to 10 µA. These values are measured under pulsed conditions (PW = 30 ms) and impact standby power loss in high-voltage hold-up circuits.
How does the junction-to-case thermal resistance of the SFAF2006G affect heatsink selection?
With RθJC = 3°C/W, the SFAF2006G transfers heat efficiently from die to case. For a 20 A load at 1.3 VF, power dissipation is ~26 W; assuming 100°C max case temperature and 40°C ambient, total system RθCA must be ≤ 2.3°C/W. This dictates minimum heatsink size and interface material performance to avoid exceeding TJ = 150°C.
