Product details
Overview
SFAF2007GHC0G from Taiwan Semiconductor is a 20A, 600V super fast rectifier diode in ITO-220AC package, featuring 1.700V forward voltage at 20A/25°C, 35ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in high-frequency DC-DC converters requiring low conduction loss and fast switching.
For engineers reviewing the SFAF2007GHC0G datasheet, SFAF2007GHC0G pinout, SFAF2007GHC0G application, or SFAF2007GHC0G equivalent, key selection criteria include its 600V VRRM, 200A IFSM, 3°C/W RθJC, junction temperature range (–55°C to +150°C), and AEC-Q101 qualification status - all critical for automotive power supply and industrial SMPS designs.
Technical Context
This device employs a single-die, glass-passivated silicon junction optimized for high-efficiency switching applications. Its 35ns trr and low 1.700V VF at rated current enable reduced switching losses and thermal stress in 100–500kHz DC-DC topologies.
The ITO-220AC package provides direct metal-to-heatsink mounting with 0.56 N·m max torque and UL 94V-0 molding compound. Polarity is marked on the case, and terminals are matte tin-plated per J-STD-002 for reliable solderability.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2006D | 600V VRRM, 20A IF, 35ns trr, but TO-220AC package with non-isolated tab | Requires insulated mounting hardware; lacks AEC-Q101 qualification | Preferred where cost sensitivity outweighs automotive qualification needs |
| IXYS MUR2060CT | Dual common-cathode configuration; 600V, 2×10A, 60ns trr, TO-220AB package | Not single-diode; higher trr increases switching loss in high-frequency designs | Only suitable when dual-output or lower-cost dual-die layout is acceptable |
Compared with STTH2006D and IXYS MUR2060CT, the SFAF2007GHC0G uniquely combines AEC-Q101 compliance, isolated ITO-220AC tab, and 35ns trr at 600V - making it the only option qualified for automotive-grade 20A rectification without thermal or reliability trade-offs.

FAQ
What is the maximum junction temperature rating for SFAF2007GHC0G?
The SFAF2007GHC0G has a maximum junction temperature (TJMAX) of +150°C, verified per AEC-Q101 stress testing. This rating allows operation in under-hood automotive environments and high-ambient industrial settings when paired with appropriate heatsinking based on its 3°C/W RθJC. Derating curves in the official datasheet define allowable IF vs. TC limits.
Is SFAF2007GHC0G pin-compatible with standard ITO-220AC rectifiers?
Yes, the SFAF2007GHC0G uses the industry-standard ITO-220AC mechanical outline with identical lead pitch, tab dimensions, and mounting hole placement. Its cathode-connected tab and anode lead 1 match conventional ITO-220AC rectifier pinout, enabling drop-in replacement in existing layouts - provided thermal and isolation requirements align.
Does SFAF2007GHC0G meet halogen-free and RoHS requirements?
Yes, the SFAF2007GHC0G is both RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and all terminations use matte tin plating meeting J-STD-002 solderability standards - confirmed in Taiwan Semiconductor's material declaration documents.
What is the reverse recovery time (trr) specification for SFAF2007GHC0G?
The SFAF2007GHC0G 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 enables efficient operation in switching power supplies operating up to 500 kHz without significant commutation loss.
How does the AEC-Q101 qualification impact SFAF2007GHC0G's use in non-automotive applications?
The AEC-Q101 qualification of SFAF2007GHC0G validates its robustness against temperature cycling, high-temperature operating life, and mechanical shock - benefits that extend to industrial and telecom applications requiring extended field life and high reliability. While not mandatory outside automotive, this qualification provides measurable margin in harsh-environment deployments.
