Product details

Overview

FR107G 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 30 A surge capability - deployed in high-voltage DC-DC converters and switching inverters.

For engineers reviewing the FR107G datasheet, FR107G pinout, FR107G application, or FR107G equivalent, key selection criteria include verified V_RRM = 1000 V, I_F = 1 A continuous rating, t_rr = 500 ns, thermal resistance R_θJA = 70 °C/W, and DO-41 mechanical compatibility with legacy through-hole power supplies.

Technical Context

The FR107G operates as a single-die, unidirectional fast recovery rectifier optimized for high-voltage switching-mode power conversion. Its glass-passivated junction ensures stable leakage performance up to 125 °C, while the 500 ns t_rr enables efficient operation in 20–100 kHz SMPS topologies.

Designed for line-frequency and high-frequency rectification, it sustains 1000 V repetitive peak reverse voltage with only 5 µA max reverse current at 25 °C and 100 µA at 125 °C - critical for maintaining efficiency in thermally constrained industrial inverters and AC-DC front-ends.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - supports direct rectification of 700 V_RMS AC inputs without derating
I_F	1 A continuous - suitable for low-to-medium power DC-DC stages up to ~15 W at 12 V output
t_rr	500 ns - enables use in 50–100 kHz flyback and forward converters with minimal switching loss
V_F max	1.3 V @ 1 A, 25 °C - contributes ≤1.3 W conduction loss per diode in series-fed configurations
I_FSM	30 A @ 8.3 ms - withstands cold-start surges and transient overloads in offline SMPS
R_θJA	70 °C/W - requires minimal heatsinking when mounted on standard FR-4 PCB with 1 cm² copper pour

Equivalent & Alternatives

The following parts are listed as comparable options for similar fast recovery rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R06	V_RRM = 600 V, t_rr = 50 ns, I_F = 1 A, DO-41	Limited to ≤420 V_RMS AC inputs; unsuitable for 1000 V systems	Select when lower t_rr is prioritized over voltage rating - e.g., high-frequency resonant converters
1N5622	V_RRM = 1000 V, t_rr = 250 ns, I_F = 1 A, DO-41, higher V_F (1.7 V)	Higher conduction loss; not AEC-Q101 qualified	Choose where cost sensitivity outweighs efficiency and automotive qualification needs

Compared with STTH1R06 and 1N5622, the FR107G uniquely balances 1000 V blocking, 500 ns recovery, and AEC-Q101 availability in DO-41 - making it optimal for industrial and automotive-grade 1 A, high-voltage rectification where reliability and voltage margin are non-negotiable.

FAQ

What is the maximum junction temperature rating for FR107G?

The FR107G has a maximum junction temperature (T_J) of +150 °C, validated across its full operating range. This rating enables reliable operation in enclosed industrial enclosures and automotive under-hood environments when mounted with adequate copper area. The FR107G maintains specified electrical parameters - including 100 µA reverse current at 125 °C - up to this limit.

Is FR107G pin-compatible with other DO-41 fast recovery diodes?

Yes, the FR107G uses the standard DO-204AL (DO-41) axial package with anode and cathode leads spaced per JEDEC DO-41 outline. It is mechanically interchangeable with any DO-41 rectifier, including 1N4007 and STTH1R06, though electrical parameters - especially V_RRM, t_rr, and V_F - differ significantly. Always verify circuit stress margins before substitution.

Does FR107G meet automotive qualification standards?

The base FR107G is not AEC-Q101 qualified, but Taiwan Semiconductor offers the FR107GH variant - identical electrically and mechanically, with full AEC-Q101 stress testing including HTOL, TC, and UHAST. For automotive applications, specify FR107GH; the "H" suffix denotes qualification, not a different die or package.

What is the reverse recovery time (t_rr) of FR107G and how is it measured?

The FR107G has a reverse recovery time (t_rr) of 500 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per JEDEC test method JESD28-C. This value reflects performance in typical switching converter conditions and is confirmed across production lots - enabling accurate loss modeling in 20–100 kHz power stages.

Can FR107G replace FR106G in existing designs?

Yes, the FR107G is a direct upgrade from FR106G (800 V) with identical package, pinout, and thermal characteristics - only V_RRM increases to 1000 V and t_rr remains 500 ns. No layout or thermal changes are needed; the higher voltage rating improves safety margin in high-line or transient-prone AC-DC applications without affecting efficiency or footprint.
