Product details
Overview
FR307G-K from Taiwan Semiconductor is a 1000V, 3A fast recovery rectifier diode in DO-201AD package, featuring 500 ns reverse recovery time, 1.3 V forward voltage at 3 A, and 125 A surge capability - used in high-voltage DC-DC converters and switching inverters.
For engineers reviewing the FR307G-K datasheet, FR307G-K pinout, FR307G-K application, or FR307G-K equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (35 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance for industrial power supply designs.
Technical Context
This single-die fast recovery rectifier operates with low conduction loss due to its 1.3 V VF at 3 A and maintains reliability under repetitive surge stress up to 125 A (8.3 ms half-sine). Its 500 ns trr enables efficient operation in medium-frequency switching topologies.
The device uses pure tin-plated leads compliant with J-STD-002, meets JESD 201 Class 1A whisker resistance, and is encapsulated in UL 94V-0 molding compound - supporting automated assembly and long-term field stability in harsh ambient conditions.
Key Specifications

| IF | 3 A continuous - rated for sustained output current in compact 30 W–60 W power supplies |
| trr | 500 ns - enables stable operation up to ~100 kHz switching frequency without excessive switching loss |
| VF @ 3 A | 1.3 V - contributes to <1.5 W conduction loss at full load, reducing heatsink requirements |
| RθJA | 35 °C/W - allows ~35 °C rise above ambient at 3 A, enabling natural-convection cooling in sealed enclosures |
| IFSM | 125 A - withstands inrush surges during cold-start of AC/DC adapters and motor drives |
| TJ max | +150 °C - supports operation in high-ambient environments such as industrial control cabinets |

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 | 600 V VRRM, TO-220AC package, 50 ns trr, VF = 1.15 V @ 3 A | Better speed & lower VF but lower voltage rating; requires heatsink mounting | Select when higher efficiency at <600 V and forced-air cooling are available |
| VS-3EYH02-M3 | 200 V VRRM, SMA package, 35 ns trr, VF = 0.92 V @ 3 A | Optimized for low-voltage, high-speed apps; not suitable for >200 V circuits | Choose only for secondary-side or low-VDC bus rectification where voltage stress is <200 V |
Compared with STTH3L06S and VS-3EYH02-M3, the FR307G-K uniquely balances 1000 V capability, through-hole DO-201AD compatibility, and 500 ns recovery - making it optimal for cost-sensitive, high-voltage, naturally-cooled industrial power stages where voltage margin and layout continuity are critical.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for FR307G-K?
The FR307G-K has a VRRM rating of 1000 V, confirmed in the Absolute Maximum Ratings table. This allows the FR307G-K to be used directly in universal-input offline power supplies and high-voltage DC-DC converters without series stacking or derating, provided design margins account for transient overvoltage events per IEC 61000-4-5.
Does FR307G-K meet RoHS and halogen-free requirements?
Yes, the FR307G-K is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section. The device uses green molding compound and pure tin-plated leads, satisfying both environmental compliance and solderability standards (J-STD-002) required for modern electronics manufacturing.
What is the reverse recovery time (trr) of FR307G-K, and how is it measured?
The FR307G-K has a trr of 500 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the Electrical Specifications table. This value applies specifically to FR306G-K and FR307G-K variants and reflects performance in medium-frequency switching applications - distinct from faster variants like FR301G-K (150 ns).
Can FR307G-K replace FR306G-K in an existing design?
Yes, the FR307G-K is a direct upgrade from FR306G-K (800 V) with identical DO-201AD package, pinout, thermal characteristics, and electrical behavior except for higher VRRM (1000 V vs. 800 V). No PCB or layout changes are needed, and the FR307G-K provides additional voltage margin for improved system reliability under line transients.
What is the junction-to-ambient thermal resistance (RθJA) of FR307G-K?
The FR307G-K has a typical RθJA of 35 °C/W, specified in the Thermal Performance section. This value assumes standard JEDEC test conditions (single device on 1-inch² copper pad) and enables estimation of junction temperature rise under real-world conduction loss - critical for thermal validation in enclosed or high-ambient environments.
