Taiwan Semiconductor Corporation FR206G-T

Overview

FR206G-T 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 low conduction loss.

For engineers reviewing the FR206G-T datasheet, FR206G-T pinout, FR206G-T application, or FR206G-T equivalent, key selection criteria include rated V_RRM = 800 V, I_F = 2 A, t_rr = 500 ns, thermal resistance R_θJA = 70 °C/W, and DO-15 mechanical compatibility with standard through-hole layouts.

Technical Context

This single-die fast recovery rectifier employs glass-passivated junction technology to achieve stable reverse blocking up to 800 V and low forward voltage drop. Its 500 ns recovery time enables operation in medium-frequency SMPS topologies (e.g., 50–100 kHz flyback and forward converters) without excessive switching loss.

The device operates across –55°C to +150°C junction temperature range, supports 55 A non-repetitive surge current (8.3 ms half-sine), and exhibits <5 µA reverse leakage at 25°C - critical for maintaining efficiency in standby and light-load conditions.

Key Specifications

FAQ

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

The FR206G-T has a V_RRM rating of 800 V, as specified in the Absolute Maximum Ratings table. This value defines the highest reverse voltage the diode can block repeatedly without breakdown under normal operating conditions. It is critical for ensuring safe operation in 400 VDC bus applications with adequate derating margin. The FR206G-T datasheet confirms this parameter applies specifically to the FR206G-T variant within the FR201G-T to FR207G-T family.

What is the forward voltage drop (V_F) of FR206G-T at rated current?

The FR206G-T exhibits a maximum forward voltage of 1.3 V at I_F = 2 A and T_J = 25°C, per the Electrical Specifications table. This V_F value directly determines conduction loss (P_cond ≈ I_F × V_F) and influences thermal design. The actual V_F may decrease slightly at lower currents or increase at elevated junction temperatures, as shown in the Typical Forward Characteristics curve in the FR206G-T datasheet.

Does FR206G-T have a defined reverse recovery time (t_rr)?

Yes, the FR206G-T has a specified reverse recovery time of 500 ns, measured under conditions I_F = 0.5 A, I_R = 1.0 A, and I_rr = 0.25 A. This parameter is explicitly assigned to FR206G-T and FR207G-T in the Electrical Specifications table. It reflects the diode's ability to transition from conduction to blocking state, impacting switching losses in high-frequency converters.

What package type does FR206G-T use, and what are its key mechanical features?

The FR206G-T uses the DO-204AC (DO-15) axial-leaded package. Key mechanical features include glass-passivated chip junction, pure tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, and cathode polarity indicated by a visible band. Its weight is approximately 0.400 g, and it meets JESD 201 Class 1A whisker test requirements - all confirmed in the Mechanical Data section of the FR206G-T datasheet.

Is FR206G-T RoHS and halogen-free compliant?

Yes, the FR206G-T is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as stated in the FEATURES section of the official Taiwan Semiconductor datasheet. This compliance is verified for the entire FR201G-T to FR207G-T series, including the FR206G-T variant, and applies to both material content and manufacturing process.
