Taiwan Semiconductor Corporation FR107G-K

Overview

FR107G-K from Taiwan Semiconductor is a 1A, 1000V fast recovery rectifier diode in DO-204AL (DO-41) package, featuring 500 ns reverse recovery time, 1.3 V max forward voltage at 1 A, and 5 µA max reverse leakage at 25°C - used in high-voltage DC-DC converters and switching inverters.

For engineers reviewing the FR107G-K datasheet, FR107G-K pinout, FR107G-K application, or FR107G-K equivalent, key selection criteria include peak reverse voltage rating (1000 V), surge current capability (30 A), thermal resistance (70 °C/W), junction temperature range (–55 to +150 °C), and RoHS/halogen-free compliance for industrial power conversion designs.

Technical Context

This single-die, glass-passivated fast recovery rectifier supports high-efficiency switching operation with low conduction loss and controlled reverse recovery behavior. Its 1000 V V_RRM and 500 ns t_rr enable use in 600–1000 V bus applications where rapid turn-off minimizes switching losses.

The device operates across –55 °C to +150 °C junction temperature, features pure tin-plated leads compliant with J-STD-002, and meets UL 94V-0 flammability and JESD201 Class 1A whisker resistance standards - confirming suitability for reliable, high-volume industrial power supplies.

FAQ

What is the maximum junction temperature rating for FR107G-K?

The FR107G-K has a maximum junction temperature (T_J) of +150 °C and a minimum of –55 °C. This wide operating range allows deployment in harsh environments such as industrial motor drives and outdoor power supplies. Thermal design must ensure R_θJA = 70 °C/W is respected under full 1 A load to avoid exceeding T_J limit. The FR107G-K datasheet specifies derating curves for ambient temperatures above 75 °C.

Is FR107G-K RoHS and halogen-free compliant?

Yes, FR107G-K is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound meets UL 94V-0 flammability rating, and the pure tin-plated leads satisfy J-STD-002 solderability requirements. These certifications are confirmed in Taiwan Semiconductor's official documentation for FR101G-K through FR107G-K revision B2104, making FR107G-K suitable for export-controlled and eco-regulated end equipment.

What is the reverse recovery time (t_rr) of FR107G-K and how is it tested?

The FR107G-K has a reverse recovery time (t_rr) of 500 ns, measured under conditions I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A per the FR101G-K–FR107G-K datasheet. This value reflects the time required for minority carriers to clear after forward conduction, directly impacting switching loss in high-frequency topologies. The FR107G-K's t_rr is consistent across its rated temperature range and validated using standardized pulse test waveforms.

Can FR107G-K replace FR106G-K in an existing design?

Yes, FR107G-K can replace FR106G-K (800 V) in most cases because it shares identical package (DO-41), pinout, forward current (1 A), and thermal characteristics, while offering higher V_RRM (1000 V vs. 800 V). No PCB changes are needed. However, verify that the increased voltage rating does not affect snubber design or stress on adjacent components - the FR107G-K itself remains functionally compatible and electrically safe in the same layout.

What packaging options are available for FR107G-K?

FR107G-K is supplied in two standard packaging formats: 5,000 units per tape-and-reel (ordering code FR107G-K) and 3,000 units per ammo box (ordering code FR107G-K A0G). Both use DO-204AL (DO-41) packaging with cathode band marking and green compound. Tape-and-reel is optimized for SMT placement compatibility, while ammo box supports manual or semi-automated through-hole assembly - both options maintain full traceability and comply with Taiwan Semiconductor's quality control protocols.
