Product details
Overview
FR307GH from Taiwan Semiconductor is an AEC-Q101 qualified fast recovery rectifier diode in DO-201AD package, rated for 3A average forward current, 1000V repetitive peak reverse voltage, and 500ns reverse recovery time at IF = 0.5A, IR = 1.0A, Irr = 0.25A - used in high-efficiency DC-DC converters and automotive-grade switching inverters.
For engineers reviewing the FR307GH datasheet, FR307GH pinout, FR307GH application, or FR307GH equivalent, key selection criteria include its AEC-Q101 qualification, 1000V VRRM rating, 500ns trr, 1.3V max VF at 3A, and DO-201AD mechanical compatibility with high-surge (125A IFSM) and high-temperature (150°C TJ max) operation.
Technical Context
This single-die fast recovery rectifier uses optimized PN junction design to achieve low forward voltage drop and controlled minority-carrier lifetime, enabling reduced conduction and switching losses in high-frequency switching topologies. Its 500ns reverse recovery time and 30pF junction capacitance support stable operation up to several hundred kHz in SMPS designs.
The device operates across –55°C to +150°C junction temperature range, with 35°C/W junction-to-ambient thermal resistance in standard PCB mount configuration. It meets JESD201 Class 2 whisker resistance and RoHS/halogen-free requirements per IEC 61249-2-21.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH3L06S | 600V VRRM, 3A IF, 60ns trr, TO-220AC package | Lower voltage rating; faster recovery but larger footprint and higher thermal mass | Preferred where <600V blocking suffices and ultra-fast recovery is critical |
| ON Semiconductor MUR3100E | 1000V VRRM, 3A IF, 60ns trr, DO-201AD package, no AEC-Q101 | Same package and voltage rating, but lacks automotive qualification and has tighter trr spec | Cost-sensitive industrial designs where AEC-Q101 is not required |
Compared with STTH3L06S and MUR3100E, FR307GH uniquely combines 1000V blocking, AEC-Q101 qualification, and DO-201AD compatibility - making it the only option among the three validated for under-hood automotive converters requiring both high voltage and reliability assurance.

FAQ
What is the maximum junction temperature rating for FR307GH?
The FR307GH has a maximum junction temperature (TJ max) of +150°C, verified per AEC-Q101 stress testing. This allows operation in under-hood automotive environments and high-ambient industrial settings without additional derating beyond the published forward current derating curve. The FR307GH maintains specified electrical parameters up to this limit when thermal design meets RθJA = 35°C/W requirements.
Is FR307GH pin-compatible with other devices in the FR30xG family?
Yes, FR307GH shares identical DO-201AD package dimensions, lead spacing, and polarity marking (cathode band) with all FR301G–FR306G variants. All members use the same mechanical outline and mounting footprint, enabling board-level substitution within voltage-rated constraints - e.g., FR307GH can replace FR305G where 1000V blocking margin is needed, provided layout accommodates same thermal pad area.
What does the 'H' suffix signify in FR307GH?
The 'H' suffix in FR307GH indicates full AEC-Q101 qualification per Rev D requirements, including HTSL, TC, AC/DC life tests, and ESD verification. This distinguishes FR307GH from standard FR307G, which lacks automotive qualification. The FR307GH undergoes extended reliability screening and is traceable to automotive-grade wafer lots and assembly lines.
What is the reverse recovery time (trr) specification for FR307GH?
The FR307GH has a maximum reverse recovery time (trr) of 500 ns under conditions IF = 0.5A, IR = 1.0A, Irr = 0.25A, measured per JEDEC JESD282B. This value is confirmed for the FR307G variant in the official TSC datasheet (Version H2105, Page 2). The FR307GH retains identical electrical timing characteristics as FR307G, with qualification adding only reliability validation - not parameter change.
Does FR307GH meet halogen-free and RoHS requirements?
Yes, FR307GH complies with RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21, using bromine- and chlorine-free molding compound. Lead finish is pure tin (Pb-free), qualified to J-STD-002 for solderability. These material specifications are explicitly stated in the FR301G–FR307G datasheet (Page 1, Features section) and apply identically to FR307GH.
