Product details
Overview
SFAF2002GH from Taiwan Semiconductor is a 20A, 100V AEC-Q101-qualified super fast rectifier diode in ITO-220AC package, featuring 0.975V forward voltage at 20A/25°C, 35ns reverse recovery time, and 200A surge capability - deployed in automotive DC-DC converters and industrial switching inverters.
For engineers reviewing the SFAF2002GH datasheet, SFAF2002GH pinout, SFAF2002GH application, or SFAF2002GH equivalent, key selection criteria include VRRM=100V, IF=20A, trr=35ns, RθJC=3°C/W, and AEC-Q101 qualification for under-hood power conversion designs.
Technical Context
This super fast rectifier uses glass-passivated junction technology to achieve low conduction loss and high reliability under repetitive surge stress. Its 35ns reverse recovery time and 0.975V forward voltage at rated current enable high-frequency switching efficiency in hard-switched topologies.
The ITO-220AC package provides direct heatsink mounting with 0.56 N·m torque limit and meets UL 94V-0 flammability rating. Polarity is marked on the device body, and terminals are matte tin-plated per J-STD-002 solderability standard.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines usable DC bus voltage headroom in 12–48V automotive systems |
| IF | 20 A - Continuous forward current rating at case temperature ≤85°C; supports sustained power delivery in compact converters |
| IFSM | 200 A - Non-repetitive surge current (8.3ms half-sine); withstands startup inrush and fault transients |
| trr | 35 ns - Reverse recovery time at IF=0.5A, IR=1.0A, Irr=0.25A; enables operation up to ~2 MHz switching frequency |
| VF | 0.975 V - Forward voltage at IF=20A, TJ=25°C; contributes <19.5W conduction loss at full load |
| RθJC | 3 °C/W - Junction-to-case thermal resistance; allows ~67W max power dissipation with 200°C ΔT to heatsink |
| CJ | 170 pF - Junction capacitance at 1MHz, VR=4V; impacts snubber design and EMI filtering in high-dV/dt circuits |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2002D | VRRM=100V, IF=20A, trr=35ns, but VF=1.05V @20A and not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial-only deployments with relaxed reliability requirements | Select when AEC-Q101 is not required and higher VF is acceptable for thermal budget |
| IXYS MUR2010CT | Dual common-cathode configuration, VRRM=100V, IF=20A per diode, trr=35ns, VF=0.92V, AEC-Q101 available only in non-H variant | Requires PCB layout change due to dual-diode footprint and different pinout; no H-grade AEC-Q101 version | Choose only if dual-diode topology is needed and automotive qualification can be waived |
Compared with STTH2002D and IXYS MUR2010CT, the SFAF2002GH uniquely combines AEC-Q101 qualification, 0.975V VF, and single-diode ITO-220AC packaging - making it optimal for space- and reliability-constrained automotive power stages where pin compatibility and qualification are mandatory.

FAQ
What is the maximum junction temperature rating for the SFAF2002GH?
The SFAF2002GH has a maximum junction temperature (TJ) rating of +150°C, with operational storage temperature spanning –55°C to +150°C. This rating supports deployment in under-hood automotive environments and high-ambient industrial enclosures. Thermal design must maintain TJ ≤150°C using the specified RθJC=3°C/W and appropriate heatsinking. The SFAF2002GH datasheet confirms this limit applies across all operating conditions.
Is the SFAF2002GH pin-compatible with other devices in the SFAF200xG series?
Yes, the SFAF2002GH shares identical ITO-220AC package dimensions, pinout, and mounting interface with all SFAF2001G–SFAF2008G variants. Only VRRM and associated electrical parameters differ across the series. Mechanical integration, PCB layout, and heatsink interface remain unchanged when substituting within the family, including the SFAF2002GH.
Does the SFAF2002GH meet RoHS and halogen-free requirements?
Yes, the SFAF2002GH is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound is UL 94V-0 rated, and terminals are matte tin-plated to J-STD-002 standards. These compliance attributes are explicitly stated in the official Taiwan Semiconductor documentation for the SFAF2002GH and verified in its ordering code suffix "H".
What is the reverse leakage current specification for the SFAF2002GH at elevated temperature?
At TJ=125°C and rated VR, the SFAF2002GH exhibits a maximum reverse leakage current (IR) of 400 µA. At TJ=25°C, the limit is 10 µA. These values are measured under pulse conditions (PW=30ms) and reflect stable performance across automotive temperature ranges. The SFAF2002GH maintains low leakage even at high junction temperatures, supporting reliable blocking in high-voltage DC links.
How does the "H" suffix in SFAF2002GH affect its qualification status?
The "H" suffix in SFAF2002GH explicitly denotes AEC-Q101 qualification, distinguishing it from non-H variants like SFAF2002G. This qualification includes stress testing for temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing (uHAST). The SFAF2002GH is certified for automotive power electronics applications where reliability under thermal and mechanical stress is mandatory.
