Product details
Overview
FR307G from Taiwan Semiconductor is a single-die fast recovery rectifier in DO-201AD package, rated for 3A average forward current, 1000V repetitive peak reverse voltage (VRRM), and 500ns reverse recovery time (trr), used in high-efficiency DC-DC converters and switching inverters operating up to 150°C junction temperature.
For engineers reviewing the FR307G datasheet, FR307G pinout, FR307G application, or FR307G equivalent, key selection criteria include its 1000V VRRM, 125A non-repetitive surge rating (IFSM), low 1.3V forward voltage at 3A, 5µA max reverse leakage at 25°C, and AEC-Q101 qualification option (FR307GH).
Technical Context
This device operates as a unidirectional power rectifier with fast recovery characteristics optimized for high-frequency switching topologies. Its DO-201AD package supports 35°C/W junction-to-ambient thermal resistance and accommodates 1.20g mass with pure tin-plated leads compliant with J-STD-002 solderability.
The FR307G exhibits 30pF junction capacitance at 1MHz/4V and maintains ≤100µA reverse leakage at 125°C - critical for thermal stability in compact power stages. Polarity is marked by cathode band; no internal series/parallel configuration is present.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - blocks up to 1000V reverse voltage without breakdown in continuous operation |

| VF | 1.3 V @ 3A, 25°C - low conduction loss improves system efficiency and reduces heatsink requirements |
| IFSM | 125 A - withstands short-duration line surges or startup transients without failure |
| RθJA | 35 °C/W - defines thermal performance in free-air mounting; requires PCB copper area for derating |

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, 65ns trr, TO-220AC package | Lower voltage rating; faster recovery but higher VF (1.7V) | Preferred where <600V blocking suffices and ultra-fast recovery is prioritized over thermal footprint |
| ON Semi MUR3100E | 1000V VRRM, 3A IF, 60ns trr, DO-201AD package | Superior speed (60ns vs. 500ns), same package, but higher VF (1.75V) and no AEC-Q101 option | Selected when minimizing reverse recovery loss dominates over conduction loss in high-frequency designs |
Compared with STTH3L06S and MUR3100E, the FR307G trades speed for lower forward drop and automotive qualification readiness - making it optimal for cost-sensitive, thermally constrained 1000V industrial converters where 500ns trr is sufficient.

FAQ
What is the maximum junction temperature rating for FR307G?
The FR307G has a maximum junction temperature (TJ) of +150°C and a minimum of −55°C. This wide operating range allows deployment in under-hood automotive environments and high-temperature industrial enclosures. Derating curves in the FR301G–FR307G datasheet define safe IF limits versus ambient temperature, and the DO-201AD package's 35°C/W RθJA must be considered in thermal design. FR307G maintains electrical integrity within this full range when mounted per recommended pad layout.
Does FR307G have AEC-Q101 qualification?
The standard FR307G is not AEC-Q101 qualified; however, the FR307GH variant - identical in electrical and mechanical specs except for extended reliability testing - is fully AEC-Q101 qualified. FR307GH undergoes temperature cycling, high-temperature reverse bias (HTRB), and accelerated moisture resistance tests per AEC-Q101 Rev D. For automotive applications requiring qualification, FR307GH must be explicitly ordered using the "H" suffix.
What is the reverse recovery time (trr) of FR307G and how is it measured?
The FR307G has a reverse recovery time (trr) of 500ns, measured under conditions of IF = 0.5A, IR = 1.0A, and Irr = 0.25A per the FR301G–FR307G datasheet. This value reflects the time required for minority carriers to clear after forward conduction ceases, directly impacting switching loss in high-frequency topologies. The 500ns trr is consistent across all FR306G and FR307G devices and is validated using the test circuit shown in Figure 6 of the datasheet.
What packaging options are available for FR307G?
FR307G is supplied in DO-201AD package with two standard packing formats: 1,250 units per tape-and-reel (ordering code FR307G) and 500 units per ammo box (ordering code FR307G A0G). Tape-and-reel is recommended for automated SMT placement, while ammo box suits manual prototyping or low-volume assembly. Both options feature green molding compound and cathode-band polarity marking per the DO-201AD outline drawing.
How does FR307G compare to FR306G in terms of voltage rating and application suitability?
FR307G is rated for 1000V VRRM, whereas FR306G is rated for 800V VRRM; both share identical IF = 3A, trr = 500ns, and DO-201AD packaging. FR307G is selected where system-level transient overvoltage or safety margin demands ≥1000V blocking - such as in 800V+ EV charging stages or industrial 3-phase rectification. FR306G remains suitable for 600–750V DC bus applications with tighter cost constraints.
