Product details
Overview
SF61GHA0G from Taiwan Semiconductor is a 50V, 6A super fast rectifier diode in DO-201AD package, featuring 0.975V forward voltage at 6A/25°C, 35ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in DC-DC converters requiring low conduction loss and fast switching.
For engineers reviewing the SF61GHA0G datasheet, SF61GHA0G pinout, SF61GHA0G application, or SF61GHA0G equivalent, key selection criteria include repetitive peak reverse voltage (50V), surge current rating (150A), junction-to-lead thermal resistance (5°C/W), and AEC-Q101 qualification status - all critical for high-reliability power conversion designs.
Technical Context
The SF61GHA0G employs a single-die silicon PN junction optimized for super-fast recovery (trr ≤ 35ns) under IF = 0.5A, IR = 1.0A, Irr = 0.25A test conditions. Its low VF (max 0.975V @ 6A, 25°C) and high IFSM (150A, 8.3ms half-sine) support high-efficiency, high-current switching applications.
Thermally, it delivers RθJL = 5°C/W and RθJA = 40°C/W in DO-201AD package, enabling stable operation up to TJ = 150°C. Polarity is indicated by cathode band; terminals are pure tin-plated per J-STD-002 and pass JESD201 Class 2 whisker testing.
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 |
|---|---|---|---|
| STTH6L06S | 600V VRRM, 1.7V VF @ 6A, TO-220AC package, non-AEC-Q101 | Higher voltage grade; unsuitable for 50V systems due to excessive VF penalty | Select only if higher reverse voltage margin is required and AEC-Q101 is not mandatory |
| ON Semi MUR620CT | Dual common-cathode configuration, 200V VRRM, 1.7V VF @ 6A, TO-220AB | Not single-diode; requires layout change and offers no AEC-Q101 qualification | Use only in dual-output or cost-sensitive non-automotive designs where footprint and qualification are secondary |
Compared with STTH6L06S and MUR620CT, the SF61GHA0G uniquely combines 50V optimization, AEC-Q101 qualification, and DO-201AD form factor - delivering lowest VF and smallest footprint for automotive 12V subsystems requiring high reliability and thermal efficiency.

FAQ
What is the maximum junction temperature rating for SF61GHA0G?
The SF61GHA0G has a maximum junction temperature (TJ MAX) of +150°C, validated across its full operating range from −55°C to +150°C. This rating enables reliable operation in under-hood automotive environments and high-ambient industrial settings. Derating curves in the official datasheet define allowable average forward current versus case temperature, ensuring thermal safety at elevated ambient conditions. The SF61GHA0G maintains specified electrical parameters up to this limit when mounted per recommended PCB thermal pad guidelines.
Is SF61GHA0G pin-compatible with other SF6xG variants like SF62GHA0G?
Yes, SF61GHA0G is mechanically and electrically pin-compatible with all SF6xGHA0G variants (SF62GHA0G through SF68GHA0G) because they share identical DO-201AD packaging, anode/cathode terminal configuration, and lead finish. However, electrical differences - especially VRRM (50V vs. 100–600V) and VF (0.975V vs. up to 1.7V) - require circuit-level verification. The SF61GHA0G must not be substituted into designs specifying higher reverse voltage without confirming blocking margin and leakage behavior.
Does SF61GHA0G meet halogen-free and RoHS requirements?
Yes, SF61GHA0G complies with both RoHS Directive 2011/65/EU and halogen-free standards per IEC 61249-2-21. The molding compound contains no brominated flame retardants, chlorine, or fluorine above threshold limits, and the pure tin-plated leads satisfy J-STD-002 solderability requirements. These certifications are documented in Taiwan Semiconductor's material declarations and apply to the full SF6xGHA0G series, including SF61GHA0G.
What is the reverse recovery time (trr) test condition for SF61GHA0G?
The reverse recovery time (trr) for SF61GHA0G is measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A, per JEDEC JESD282B.01. This standardized condition ensures consistency across super fast rectifier comparisons. The datasheet specifies trr ≤ 35 ns under these conditions, reflecting its suitability for high-frequency switching applications such as 200–500 kHz DC-DC converters. The SF61GHA0G achieves this performance via optimized carrier lifetime control in its silicon die.
How does the AEC-Q101 qualification impact SF61GHA0G's use in automotive designs?
AEC-Q101 qualification means SF61GHA0G has passed accelerated stress tests including HTGB, HTRB, TC, and ESD, validating its reliability for automotive under-hood and cabin applications. This certification allows direct use in ECU, ADAS, and body electronics without additional qualification effort. Unlike non-qualified rectifiers, the SF61GHA0G provides documented failure mechanisms and lifetime projections aligned with automotive quality standards - a requirement for Tier 1 suppliers and OEM-approved BOMs.
