Product details
Overview
SFAF2007G from Taiwan Semiconductor is a single-die, glass-passivated super fast rectifier diode in ITO-220AC package, rated for 20 A average forward current, 500 V repetitive peak reverse voltage (VRRM), and 1.700 V forward voltage at 20 A and 25°C junction temperature - used in high-efficiency DC-DC converters and freewheeling paths in automotive-grade switching inverters.
For engineers reviewing the SFAF2007G datasheet, SFAF2007G pinout, SFAF2007G application, or SFAF2007G equivalent, key selection criteria include its 500 V VRRM, 200 A non-repetitive surge rating, 35 ns reverse recovery time, 150 pF junction capacitance at 4 V, and AEC-Q101 qualification eligibility (SFAF2007GH variant).
Technical Context
This device operates as a unidirectional, single-anode–single-cathode silicon rectifier with super-fast recovery characteristics. Its 35 ns trr and low Qrr support high-frequency switching up to ~100 kHz in hard-switched topologies, while the 3°C/W junction-to-case thermal resistance enables reliable 20 A conduction at ≤125°C case temperature.
The ITO-220AC package features matte tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, and polarity marking per device body. It supports direct heatsink mounting with ≤0.56 N·m torque and meets JESD201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 500 V - maximum blocking voltage in reverse bias without breakdown; defines usable input voltage range in 400 V DC bus applications |
| IF | 20 A - continuous average forward current at TC = 100°C; supports sustained power delivery in compact converter designs |
| IFSM | 200 A - non-repetitive surge current (8.3 ms half-sine); handles inrush and fault transients without failure |
| VF | 1.700 V @ 20 A, 25°C - forward conduction loss directly impacts efficiency and thermal design in high-current paths |
| trr | 35 ns - reverse recovery time; enables stable operation in 50–100 kHz SMPS with minimal switching loss penalty |
| CJ | 150 pF @ 1 MHz, 4 V - junction capacitance affects EMI generation and snubber sizing in high-dv/dt circuits |
| RθJC | 3°C/W - thermal resistance from junction to case; determines heatsink requirement for 20 A continuous operation |
Pinout & Package
ITO-220AC package: 3-terminal, single-die, isolated tab (cathode-connected tab), through-hole mountable with screw-down heatsink interface. Tab is electrically connected to cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Tab (Metal Surface) | Cathode | Electrically tied to cathode; serves as primary thermal path and must be insulated from chassis unless circuit reference requires common-cathode grounding |
| Lead 1 (Left, viewed from front) | Anode | Main current entry point; connects to switched/high-side node in freewheeling or output rectification configurations |
| Lead 2 (Right, viewed from front) | Cathode | Secondary cathode connection; used when tab isolation is required or for dual-point cathode routing |
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 |
|---|---|---|---|
| STTH2005D | 500 V VRRM, 20 A IF, 1.75 V VF @ 20 A, 35 ns trr, TO-220AC package | Same voltage/current class but higher VF; no AEC-Q101 option | Preferred where ST ecosystem alignment or legacy footprint reuse is required; not suitable for automotive qualification-critical designs |
| VS-20EWH05 | 50 V–600 V family; VS-20EWH05 = 500 V version; 20 A IF, 1.65 V VF @ 20 A, 30 ns trr, TO-220AC | Slightly faster recovery and lower VF, but no UL recognition or halogen-free declaration in public datasheet | Consider for efficiency-optimized industrial SMPS where UL/IEC61249-2-21 compliance is not mandated |
Compared with STTH2005D and VS-20EWH05, the SFAF2007G offers verified UL recognition, halogen-free compliance, and AEC-Q101 qualification path - making it uniquely suited for safety- and automotive-certified power systems where documentation traceability and material declarations are mandatory.

FAQ
What is the maximum junction temperature rating for SFAF2007G?
The SFAF2007G has a maximum junction temperature (TJ) of +150°C, with operational capability from –55°C to +150°C. This rating enables use in high-ambient environments such as automotive engine compartments or enclosed industrial power supplies. Derating curves in the datasheet define safe IF limits above 100°C case temperature. Thermal design must respect the 3°C/W RθJC to avoid exceeding this limit under 20 A load.
Is SFAF2007G pin-compatible with other devices in the SFAF200xG family?
Yes, all SFAF2001G–SFAF2008G variants share identical ITO-220AC packaging, pinout, and mechanical dimensions. The only differences are VRRM (50 V to 600 V) and corresponding VF values - allowing drop-in replacement across voltage grades without PCB layout changes. Polarity marking and terminal configuration remain consistent across the family.
Does SFAF2007G meet automotive qualification standards?
The base SFAF2007G is not AEC-Q101 qualified, but the SFAF2007GH variant is explicitly qualified per AEC-Q101. Both share identical electrical and thermal specs; the "H" suffix denotes qualification testing including stress tests for temperature cycling, HTRB, and ESD. For automotive applications, specify SFAF2007GH to ensure compliance.
What is the reverse recovery time (trr) specification for SFAF2007G?
The SFAF2007G has a maximum reverse recovery time (trr) of 35 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed across the full operating temperature range and supports stable switching in hard-switched topologies up to 100 kHz. The 35 ns trr is identical to SFAF2005G and SFAF2006G, reflecting shared die process optimization.
How does the junction capacitance of SFAF2007G affect EMI performance?
SFAF2007G exhibits 150 pF typical junction capacitance (CJ) at 1 MHz and 4 V reverse bias - lower than earlier 50–200 V variants (170 pF). This reduced CJ minimizes high-frequency displacement current during switching transitions, lowering radiated EMI and easing snubber design in noise-sensitive applications like medical or audio power supplies.
