Product details
Overview
FR305G B0G from Taiwan Semiconductor is a 3A, 600V fast recovery rectifier diode in DO-201AD package, featuring 250 ns reverse recovery time, 1.3 V max forward voltage at 3 A, and 125 A surge capability - deployed in switching-mode DC/DC converters requiring high efficiency and thermal robustness.
For engineers reviewing the FR305G B0G datasheet, FR305G B0G pinout, FR305G B0G application, or FR305G B0G equivalent, key selection criteria include repetitive peak reverse voltage (600 V), junction-to-ambient thermal resistance (35 °C/W), AEC-Q101 qualification status, RoHS/halogen-free compliance, and DO-201AD mechanical compatibility with standard through-hole reflow or wave soldering processes.
Technical Context
This single-die fast recovery rectifier operates with low conduction loss and controlled reverse recovery behavior, optimized for high-frequency switching topologies. Its 250 ns trr and 30 pF junction capacitance support efficient operation in 50–500 kHz SMPS designs while maintaining stable thermal performance up to 150 °C junction temperature.
The device uses pure tin-plated leads compliant with J-STD-002 and passes JESD201 Class 2 whisker testing. Polarity is marked by a cathode band, and the DO-201AD case meets UL 94V-0 flammability rating - enabling use in automotive-grade and industrial power supplies where reliability under thermal cycling and surge stress is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

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 | 3 A, 600 V, 75 ns trr, TO-220AC package, higher VF (1.7 V typ) | Requires heatsink above 1.5 A; better for ultra-fast but higher-loss designs | Select when <100 ns trr is mandatory and board space allows TO-220 mounting |
| ON Semi MUR3060CT | Dual common-cathode configuration, 3 A per diode, 600 V, 60 ns trr, TO-220AB | Enables dual-output or interleaved designs; not drop-in due to dual-die pinout and package | Choose for redundancy-critical or dual-rail systems where layout revision is acceptable |
Compared with STTH3L06S and MUR3060CT, the FR305G B0G offers lower VF and DO-201AD compatibility for cost-sensitive, space-constrained through-hole applications - trading some speed for thermal simplicity and direct PCB mountability without thermal pads or clips.

FAQ
What is the maximum junction temperature rating for FR305G B0G?
The FR305G B0G has a maximum junction temperature (TJ max) of +150 °C, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version H2105). This rating enables reliable operation in enclosed industrial enclosures or near heat-generating components. Derating is required above 75 °C ambient; the FR305G B0G's 35 °C/W RθJA allows 1.2 W dissipation at 75 °C ambient before reaching TJ max.
Is FR305G B0G AEC-Q101 qualified?
No, the FR305G B0G is the standard-grade version. AEC-Q101 qualification is indicated by the "H" suffix (e.g., FR305GH). The B0G suffix denotes tape-and-reel packaging (1,250 pcs) in DO-201AD, with no automotive stress testing performed. For automotive applications, specify FR305GH or confirm qualification status via Taiwan Semiconductor's official product change notices.
What does the "B0G" suffix mean in FR305G B0G?
The "B0G" suffix in FR305G B0G identifies the packaging format: "B" = tape-and-reel, "0" = standard reel size (1,250 units), "G" = green (halogen-free) molding compound. It does not indicate AEC-Q101 qualification (that requires "H") or enhanced reliability screening. The FR305G B0G shares identical electrical and thermal specs with FR305G in other pack types.
What is the reverse recovery time (trr) of FR305G B0G, and under what conditions is it measured?
The FR305G B0G has a reverse recovery time (trr) of 250 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the Taiwan Semiconductor datasheet (Version H2105, Page 2). This value applies to the FR305G variant specifically - other members of the FR30xG family range from 150 ns (FR301G) to 500 ns (FR306G/FR307G).
Can FR305G B0G replace FR304G or FR306G in an existing design?
The FR305G B0G is not a direct replacement for FR304G (400 V) or FR306G (800 V) due to its 600 V VRRM rating - using it in place of FR304G risks overvoltage stress, while substituting for FR306G may compromise safety margin. Electrical parameters including VF, trr, and IFSM are consistent across the FR30xG series, but voltage rating must match system requirements. Always verify transient voltage margins before substitution.
