Product details

Overview

FR107GH 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 forward voltage at 1 A, and AEC-Q101 qualification for automotive-grade reliability.

For engineers reviewing the FR107GH datasheet, FR107GH pinout, FR107GH application, or FR107GH equivalent, key selection factors include its 1000 V repetitive peak reverse voltage, 30 A surge capability, glass-passivated junction, RoHS/halogen-free compliance, and suitability for high-efficiency switching-mode power supplies requiring stable thermal performance (R_θJA = 70 °C/W).

Technical Context

The FR107GH is a single-die, unidirectional silicon rectifier optimized for fast switching in DC–DC converters and inverters. Its 500 ns trr enables reduced switching losses at frequencies up to several hundred kHz, while the glass-passivated junction ensures robust moisture resistance and long-term stability under thermal cycling.

Designed for operation from –55 °C to +150 °C junction temperature, it supports high-reliability automotive and industrial applications. The device exhibits low leakage (≤100 µA at 125 °C) and low capacitance (10 pF at 4 V), minimizing parasitic effects in high-speed rectification paths.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - Withstands repetitive reverse voltages up to 1000 V without breakdown, enabling use in high-voltage DC bus rectification.
I_F	1 A continuous - Rated average forward current supports sustained conduction in compact power supplies with minimal heatsinking.
t_rr	500 ns - Fast recovery minimizes reverse recovery charge (Q_rr) and associated switching losses in SMPS operating above 50 kHz.
V_F	1.3 V @ 1 A, 25°C - Low forward drop reduces conduction loss and improves system efficiency, especially at elevated ambient temperatures.
R_θJA	70 °C/W - Junction-to-ambient thermal resistance allows direct PCB mounting in moderate-power applications without forced airflow.
I_FSM	30 A @ 8.3 ms - High surge rating accommodates inrush currents during cold-start or fault conditions in offline converters.
Junction temp. range	–55 °C to +150 °C - Wide operating range supports under-hood automotive and industrial environments with extreme thermal profiles.

Pinout & Package

Package: DO-204AL (DO-41), axial leaded, glass-passivated silicon die, cathode indicated by band. Weight: 0.340 g.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Forward current entry point	Connected to lower-potential side of circuit (e.g., transformer secondary center-tap or switch node return); must handle full 1 A DC and 30 A surge.
Cathode	Forward current exit point / reverse blocking terminal	Marked with band; connects to output capacitor or load; blocks up to 1000 V reverse bias with ≤100 µA leakage at 125 °C.

Key Features

Feature	Design Value
AEC-Q101 qualified	Validated for automotive applications including engine control units and body electronics per stress test requirements (HTOL, TC, HAST, etc.).
Glass-passivated junction	Eliminates risk of moisture-induced corrosion and parameter drift over lifetime, critical for outdoor and high-humidity deployments.
Low V_F and high I_FSM	Enables higher power density designs: 1.3 V drop at 1 A reduces heat generation vs. standard rectifiers; 30 A surge tolerance avoids derating in transient-heavy systems.
RoHS & halogen-free	Complies with IEC 61249-2-21 and EU RoHS Directive, supporting environmentally compliant manufacturing and end-of-life recycling.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH1R06U	1 A, 600 V, t_rr = 50 ns, TO-220AC package, higher thermal mass but larger footprint	Lower V_RRM limits use to ≤600 V circuits; faster t_rr suits >500 kHz topologies but requires PCB real estate for TO-220	Select when ultra-fast recovery (<100 ns) and higher surge tolerance (50 A) are prioritized over voltage rating and board space.
ON Semi MUR110E	1 A, 1000 V, t_rr = 75 ns, DO-41 package, slightly higher V_F (1.55 V), not AEC-Q101 qualified	Same package and voltage rating, but lacks automotive qualification and has 250 mV higher forward drop at 1 A	Choose for cost-sensitive industrial or consumer applications where AEC-Q101 is unnecessary and 0.25 V higher loss is acceptable.

Compared with STTH1R06U and MUR110E, FR107GH uniquely balances 1000 V rating, AEC-Q101 compliance, and DO-41 form factor-making it optimal for space-constrained automotive and industrial rectification where reliability and voltage margin outweigh ultra-fast recovery or lowest possible V_F.

FAQ

What is the maximum junction temperature rating for FR107GH?

The FR107GH has a maximum junction temperature (T_J) of +150 °C, verified per AEC-Q101 stress testing. This rating allows reliable operation in under-hood automotive environments and high-ambient industrial enclosures. Derating curves confirm 1 A continuous current is maintainable up to 125 °C ambient with standard PCB copper area, and the FR107GH remains within safe operating limits even during short-duration thermal transients.

Is FR107GH pin-compatible with other DO-41 fast recovery diodes like FR105G or MUR105?

Yes, FR107GH uses the standard DO-204AL (DO-41) axial package with identical mechanical dimensions and lead spacing as FR105G, MUR105, and other DO-41 rectifiers. The cathode band marking and polarity orientation match industry convention. However, electrical differences-including 1000 V V_RRM, 500 ns t_rr, and AEC-Q101 qualification-require verification against circuit voltage and switching speed requirements before substitution.

Does FR107GH require a heatsink in typical 1 A applications?

No, FR107GH does not require an external heatsink in typical 1 A continuous applications when mounted on a standard FR-4 PCB with ≥1 cm² of 1 oz copper connected to each lead. Its R_θJA of 70 °C/W results in ~90 °C junction rise above ambient at full load-well within the 150 °C limit. Heatsinking becomes advisable only in sealed enclosures exceeding 70 °C ambient or when operating near I_FSM limits.

What does the "H" suffix in FR107GH signify?

The "H" suffix in FR107GH indicates full AEC-Q101 qualification per Rev D, covering stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (uHAST). This distinguishes FR107GH from non-H variants (e.g., FR107G), which lack automotive reliability validation and are intended for commercial/industrial use only.

How does FR107GH's reverse recovery time compare to standard recovery diodes?

FR107GH's 500 ns reverse recovery time (t_rr) is approximately 5–10× faster than standard recovery rectifiers (e.g., 1N4007: t_rr ≈ 30 µs), significantly reducing switching losses and EMI in high-frequency converters. This enables efficient operation in quasi-resonant and LLC topologies up to 300 kHz, whereas standard diodes would overheat or fail due to excessive reverse recovery energy dissipation.
