Product details
Overview
SF61GHR0G from Taiwan Semiconductor is a 6A, 50V super fast recovery rectifier diode in DO-201AD package, featuring 0.975V forward voltage at 6A/25°C, 35ns reverse recovery time, and 150A surge capability - deployed in DC-DC converters and freewheeling paths where low conduction loss and fast switching are critical.
For engineers reviewing the SF61GHR0G datasheet, SF61GHR0G pinout, SF61GHR0G application, or SF61GHR0G equivalent, key selection criteria include VRRM = 50V, IF = 6A, trr = 35ns, RθJL = 5°C/W, and AEC-Q101 qualification status - all verified for automotive-grade power conversion designs.
Technical Context
This super fast rectifier uses a single-die silicon PN junction optimized for high-frequency switching operation. Its 35ns reverse recovery time and low 0.975V forward voltage at rated current enable efficient energy transfer in hard-switched topologies with minimal switching loss and thermal stress.
The device operates across –55°C to +150°C junction temperature range and achieves 5°C/W junction-to-lead thermal resistance, supporting high-current continuous operation when mounted on copper-clad PCBs or heatsinked leads. It meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH6L06D | VRRM = 600V, trr = 35ns, VF = 1.15V @ 6A - higher voltage rating but higher VF | Designed for 400V+ PFC and boost stages; less optimal for 12–48V output rectification due to excess VRRM overhead | Select only if system requires >100V reverse margin or shares BOM with higher-voltage variants |
| ON Semi MUR620E | VRRM = 200V, trr = 35ns, VF = 1.05V @ 6A - same speed, slightly higher VF, no AEC-Q101 certification | Targeted at industrial/commercial SMPS; lacks automotive qualification and whisker testing | Acceptable for non-automotive designs where cost sensitivity outweighs qualification requirements |
Compared with STTH6L06D and MUR620E, SF61GHR0G offers the lowest forward voltage (0.975V) at 50V rating and full AEC-Q101 compliance - making it the preferred choice for space-constrained, thermally demanding automotive DC-DC and freewheeling applications where efficiency and qualification are mandatory.

Yes, SF61GHR0G is AEC-Q101 qualified - confirmed by Taiwan Semiconductor's G2105 datasheet revision and ordering code suffix "H" (SF61GHR0G includes the "H" designation). Qualification covers HTOL, temperature cycling, HTRB, and unbiased HAST per AEC-Q101-004/005/007/012 standards, making it suitable for automotive power modules and ECUs.
What is the reverse recovery time (trr) of SF61GHR0G and how is it measured?
SF61GHR0G has a typical reverse recovery time (trr) of 35 ns, measured under standardized conditions: IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This value is specified in the Electrical Specifications table of the official datasheet and reflects performance in high-frequency switching applications such as 200–500 kHz DC-DC converters where fast minority-carrier recombination is critical.
Does SF61GHR0G have halogen-free and RoHS-compliant construction?
Yes, SF61GHR0G uses halogen-free molding compound compliant with IEC 61249-2-21 and is fully RoHS compliant per EU Directive 2011/65/EU. The device carries "G" suffix indicating green compound, and its pure tin-plated leads meet J-STD-002 solderability requirements - ensuring compatibility with lead-free reflow processes and environmental compliance mandates.
What package type and marking does SF61GHR0G use?
SF61GHR0G is housed in the DO-201AD axial-leaded package with cathode polarity indicated by a visible band. Its marking code is "SF61G", followed by date code (YWW) and factory code (F). The package features UL 94V-0 flammability rating, JESD201 Class 2 whisker resistance, and weighs approximately 1.20g - consistent with industry-standard DO-201AD mechanical specifications.
