Product details

Overview

FR206G from Taiwan Semiconductor is a 2A, 800V fast recovery rectifier diode in DO-204AC (DO-15) package, featuring 500 ns reverse recovery time, 1.3 V max forward voltage at 2 A, and 55 A surge current capability; used in switching mode power supplies and DC-DC converters requiring high efficiency and thermal robustness.

For engineers reviewing the FR206G datasheet, FR206G pinout, FR206G application, or FR206G equivalent, key selection criteria include peak reverse voltage (800 V), fast recovery performance (500 ns), thermal resistance (70 °C/W), and AEC-Q101 qualification availability for automotive-grade reliability validation.

Technical Context

The FR206G employs a glass-passivated single-die PN junction optimized for fast recovery in high-frequency switching applications. Its 800 V V_RRM and 500 ns t_rr enable efficient operation in flyback and forward converter topologies where reduced switching loss and minimal reverse recovery charge are critical.

Thermal design is supported by a junction-to-ambient thermal resistance of 70 °C/W and a maximum junction temperature of +150 °C. The device operates across –55 °C to +150 °C storage and junction ranges, with cathode polarity indicated by a band on the DO-204AC body.

I_F	2 A - Continuous average forward current; determines steady-state conduction capability without derating at 25 °C ambient
t_rr	500 ns - Reverse recovery time at I_F = 0.5 A, I_R = 1.0 A, I_rr = 0.25 A; directly impacts switching loss and EMI in SMPS above 50 kHz
V_F (max)	1.3 V @ 2 A, 25 °C - Forward voltage drop defining conduction loss; contributes ~2.6 W dissipation at full load
I_FSM	55 A - Non-repetitive surge current rating for 8.3 ms half-sine; supports inrush and fault-current handling in power-up sequences
R_θJA	70 °C/W - Junction-to-ambient thermal resistance; sets minimum heatsinking requirement for sustained 2 A operation at elevated ambient

Pinout & Package

Package: DO-204AC (DO-15), axial leaded, glass-passivated, RoHS-compliant, halogen-free molding compound (UL 94V-0), pure tin-plated leads.

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; 100 ns t_rr, higher VF (1.7 V max); TO-220AC package	Lower V_RRM limits use to ≤600 V systems; faster t_rr suits higher-frequency designs but increases conduction loss	Select when 600 V rating suffices and board space allows TO-220 mounting with heatsink
ON Semi MUR260	2 A / 600 V; 75 ns t_rr; DO-204AC package; VF = 1.7 V max	Not rated for 800 V; superior speed but higher conduction loss; no AEC-Q101 variant available	Prefer for cost-sensitive 600 V applications demanding ultra-fast recovery, not automotive qualification

Compared with STTH2R06 and MUR260, the FR206G offers higher voltage margin (800 V), lower conduction loss (1.3 V vs. ≥1.7 V), and AEC-Q101 availability-making it optimal for 800 V-rated industrial SMPS and automotive auxiliary supplies where thermal and surge robustness outweigh raw speed.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for FR206G?

The FR206G has a V_RRM rating of 800 V, meaning it can block up to 800 volts of reverse-biased DC or peak AC voltage repeatedly without breakdown. This value is fixed per the FR206G marking and is confirmed in the absolute maximum ratings table of the Taiwan Semiconductor datasheet version H2105. Exceeding this voltage risks irreversible junction failure.

Is FR206G suitable for automotive applications?

Yes-the FR206G is available in an AEC-Q101-qualified variant designated FR206GH. While the base FR206G is not certified, the GH suffix indicates full qualification per AEC-Q101 stress tests including temperature cycling, HTRB, and ESD. For automotive use, specify FR206GH to ensure compliance with under-hood reliability requirements.

What is the reverse recovery time (t_rr) of FR206G and how is it measured?

The FR206G has a reverse recovery time (t_rr) of 500 ns, measured under conditions of I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A per the electrical specifications table. This parameter reflects the time required for minority carriers to clear after forward conduction ceases, directly influencing switching loss and EMI in high-frequency converters.

Does FR206G have a halogen-free construction?

Yes-FR206G uses a halogen-free molding compound compliant with IEC 61249-2-21, verified in the mechanical data section of the official datasheet. This ensures reduced toxic gas emission during PCB assembly or end-of-life incineration, supporting environmental compliance for industrial and consumer electronics.

What is the thermal resistance (R_θJA) of FR206G and how does it affect PCB layout?

The FR206G has a junction-to-ambient thermal resistance of 70 °C/W in its standard DO-204AC package with no heatsink. This means a 2 A load at 1.3 V drop (2.6 W) will raise junction temperature by ~182 °C above ambient-exceeding the 150 °C limit. Therefore, PCB copper pour or minimal heatsinking is essential to maintain safe operation, especially above 60 °C ambient.
