Product details
Overview
SFF2001GHC0G from Taiwan Semiconductor is a 20A, 50V AEC-Q101-qualified super fast rectifier diode in ITO-220AB package with dual-die configuration, 2.5°C/W junction-to-case thermal resistance, and 35ns reverse recovery time, used in automotive-grade DC-DC converters and freewheeling paths.
For engineers reviewing the SFF2001GHC0G datasheet, SFF2001GHC0G pinout, SFF2001GHC0G application, or SFF2001GHC0G equivalent, key selection criteria include repetitive peak reverse voltage (50 V), forward current rating (20 A), surge capability (150 A), thermal resistance (2.5°C/W), and AEC-Q101 qualification status.
Technical Context
This super fast rectifier employs optimized silicon epitaxial structure to achieve low forward voltage (0.975 V at 10 A, 25°C) and fast switching (trr ≤ 35 ns), enabling high-efficiency operation in high-frequency switching topologies. Its dual-die construction supports symmetrical current sharing and thermal distribution across the ITO-220AB case.
The device meets UL 94V-0 flammability rating and JESD201 Class 2 whisker resistance, with matte tin-plated leads compliant to J-STD-002 solderability. Polarity is marked on the body, and maximum mounting torque is specified at 0.56 N·m.

| IF | 20 A - Continuous average forward current; determines heatsink sizing for sustained conduction in power supply outputs |
| IFSM | 150 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush and fault-current handling without failure |
| trr | 35 ns - Reverse recovery time; enables operation up to ~3 MHz switching frequency with minimal switching loss |
| RθJC | 2.5 °C/W - Junction-to-case thermal resistance; allows direct calculation of junction temperature rise under known case temperature |

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 | 50 V VRRM, 20 A IF, 35 ns trr, TO-220AC package (non-isolated tab) | Lacks AEC-Q101 qualification and UL recognition; not suitable for automotive under-hood use | Select when cost-sensitive industrial designs require identical electrical specs but do not mandate automotive qualification |
| VS-20EWH05-M3 | 50 V VRRM, 20 A IF, 30 ns trr, TO-247AC package; higher RθJC (1.5°C/W) but larger thermal mass | Higher surge rating (200 A), but larger footprint and non-AEC-Q101 certified | Prefer for high-reliability industrial inverters needing faster recovery and higher IFSM, where board space permits TO-247 |
Compared with STTH2005D and VS-20EWH05-M3, the SFF2001GHC0G uniquely combines AEC-Q101 qualification, UL recognition, and ITO-220AB isolation in a single 50 V/20 A super fast rectifier-making it the only option qualified for automotive power conversion where electrical isolation and safety certification are mandatory.

FAQ
What is the maximum junction temperature rating for SFF2001GHC0G?
The SFF2001GHC0G has a maximum junction temperature (TJ max) of +150°C, validated per AEC-Q101 stress testing. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in the datasheet define allowable forward current versus case temperature, and thermal design must maintain TJ ≤ 150°C under worst-case load and ambient conditions. The SFF2001GHC0G achieves this with a 2.5°C/W RθJC and robust packaging.
Is SFF2001GHC0G pin-compatible with standard TO-220 rectifiers?
No, the SFF2001GHC0G uses the ITO-220AB package, which features an electrically isolated tab-unlike standard TO-220AC or TO-220AB variants. While physical footprint and mounting hole positions match TO-220, the isolation requires verification of heatsink grounding strategy. The SFF2001GHC0G has two leads (anode and cathode) and an insulated tab; incorrect tab grounding may cause short circuits. Always consult mechanical drawings before PCB layout reuse.
Does SFF2001GHC0G meet halogen-free and RoHS requirements?
Yes, the SFF2001GHC0G is RoHS compliant and halogen-free per IEC 61249-2-21, confirmed in the official Taiwan Semiconductor specification document (Version I2105). The molding compound contains no brominated flame retardants or chlorine-based additives, and lead content is below 1000 ppm. This compliance supports environmentally regulated end equipment, including automotive ECUs and industrial control panels requiring full substance declaration.
What is the reverse recovery time (trr) specification for SFF2001GHC0G?
The SFF2001GHC0G 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 guaranteed across the full operating temperature range and supports high-frequency switching up to ~3 MHz with minimal switching loss. The fast trr directly contributes to reduced EMI and improved efficiency in DC-DC converters. The SFF2001GHC0G achieves this via optimized carrier lifetime control in its epitaxial layer.
How does the "H" suffix in SFF2001GHC0G indicate AEC-Q101 qualification?
The "H" in SFF2001GHC0G denotes AEC-Q101 qualification per Taiwan Semiconductor's ordering nomenclature (Note 2 in Ordering Information). This means the device has passed all stress tests-including HTGB, HTRB, TC, and ESD-required for discrete semiconductors in automotive applications. The "C0G" suffix indicates green compound and date code format. AEC-Q101 validation applies to the entire SFF2001GHC0G lot, not just sample units, and is documented in TSC's qualification reports.
