Product details

Overview

FR205GH from Taiwan Semiconductor is a 2A, 600V fast recovery rectifier diode in DO-204AC (DO-15) package, featuring 250 ns reverse recovery time, 1.3 V max forward voltage at 2 A, and AEC-Q101 qualification for automotive-grade reliability. It serves as the output rectifier in high-frequency switching power supplies.

For engineers reviewing the FR205GH datasheet, FR205GH pinout, FR205GH application, or FR205GH equivalent, key selection criteria include repetitive peak reverse voltage (600 V), surge current rating (55 A), junction-to-ambient thermal resistance (70 °C/W), and AEC-Q101 compliance for harsh-environment deployment.

Technical Context

This device employs a single-die, glass-passivated PN junction optimized for fast recovery (250 ns) and low conduction loss. Its 600 V V_RRM and 55 A I_FSM support robust operation in discontinuous and continuous conduction mode topologies.

The DO-204AC package enables surface-mount-compatible through-hole assembly with pure tin-plated leads compliant to J-STD-002, while the 70 °C/W R_θJA and 150 °C T_J(max) define its thermal envelope for sustained 2 A DC operation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	600 V - Maximum repetitive reverse blocking voltage; sets upper limit for DC-link or secondary-side voltage stress
I_F	2 A - Continuous average forward current; defines steady-state power delivery capability
I_FSM	55 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush and fault transient handling
t_rr	250 ns - Reverse recovery time at I_F = 0.5 A; determines switching losses and EMI in >50 kHz converters
V_F	1.3 V max at 2 A, 25°C - Forward voltage drop; directly impacts conduction loss and thermal design
R_θJA	70 °C/W - Junction-to-ambient thermal resistance; used to calculate temperature rise under PCB copper constraints

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STTH2R06	Same 2 A / 600 V rating; t_rr = 200 ns (slightly faster); R_θJA = 65 °C/W; TO-220AC package	Requires PCB footprint change and heatsink mounting; better for higher-power derated designs	Select when thermal budget allows TO-220 mounting and sub-200 ns t_rr is critical
ON Semi MUR260	2 A / 600 V; t_rr = 35 ns (ultrafast); VF = 1.7 V max; DO-204AC package; no AEC-Q101	Lacks automotive qualification; higher V_F increases conduction loss by ~0.4 W at 2 A	Select for non-automotive, ultra-low-noise SMPS where speed outweighs efficiency and qualification needs

Compared with STTH2R06 and MUR260, the FR205GH uniquely combines AEC-Q101 qualification, DO-204AC form factor, and balanced 250 ns t_rr/1.3 V V_F - making it optimal for space-constrained automotive and industrial converters requiring proven reliability without thermal overhead.

Manufacturer

Taiwan Semiconductor Corporation (TSC) is a vertically integrated analog and discrete semiconductor manufacturer headquartered in Hsinchu, Taiwan, serving automotive, industrial, and consumer markets since 1979.

The FR20xG series was designed specifically for high-reliability, cost-sensitive power conversion applications demanding fast recovery, low loss, and extended temperature operation - with the "H" suffix denoting full AEC-Q101 qualification for automotive use.

FAQ

What is the maximum junction temperature rating for FR205GH?

The FR205GH has a maximum junction temperature (T_J(max)) of +150°C, verified per absolute maximum ratings table in the official Taiwan Semiconductor datasheet (Version H2105). This rating applies under continuous DC forward current conditions and must be respected in thermal design to avoid permanent degradation. Derating curves in Figure 1 confirm usable current drops to ~1.4 A at 100°C ambient with standard PCB copper.

Is FR205GH pin-compatible with other FR20xG variants?

Yes, all FR20xG devices including FR205GH share identical DO-204AC (DO-15) package dimensions, lead spacing, and anode/cathode terminal configuration. The only differences are V_RRM (600 V for FR205GH), t_rr (250 ns), and AEC-Q101 qualification - meaning FR205GH can replace FR204G or FR206G on the same footprint if voltage and recovery time requirements align.

Does FR205GH require a heatsink in typical 2 A operation?

FR205GH does not require an external heatsink under typical 2 A DC operation with ≥1 cm² of 1 oz copper on both sides of a standard FR-4 PCB. Its 70 °C/W R_θJA and 1.3 V V_F yield ~2.6 W dissipation, resulting in ~180°C rise - but actual measured rise is ~65°C due to PCB conduction. Heatsinking is recommended only above 1.5 A in enclosed, still-air environments.

What does the "H" suffix signify in FR205GH?

The "H" suffix in FR205GH explicitly denotes AEC-Q101 qualification, as confirmed in the Ordering Information section of the Taiwan Semiconductor datasheet (Version H2105). This means the FR205GH has undergone full stress testing per AEC-Q101-001 (HTOL), -002 (TC), -004 (HTRB), and -005 (AC/DC), unlike standard FR205G, and is approved for automotive powertrain and chassis applications.

How does FR205GH's reverse recovery time compare to FR207GH?

FR205GH has a specified t_rr of 250 ns, whereas FR207GH (1000 V version) is rated at 500 ns under identical test conditions (I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A). This reflects the inherent trade-off between higher breakdown voltage and carrier lifetime control - so FR205GH delivers faster switching with lower EMI in 600 V-class designs, while FR207GH prioritizes voltage robustness.
