Taiwan Semiconductor Corporation FR207G B0G

Overview

FR207G from Taiwan Semiconductor is a 2A, 1000V 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 high-voltage DC-DC converters and switching inverters.

For engineers reviewing the FR207G datasheet, FR207G pinout, FR207G application, or FR207G equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (70 °C/W), junction temperature range (–55 to +150 °C), and AEC-Q101 qualification status for automotive-grade reliability.

Technical Context

This single-die, glass-passivated fast recovery rectifier operates with low power loss due to its 1.3 V max VF and 5 µA max IR at 25 °C. Its 500 ns trr enables efficient high-frequency switching in SMPS topologies up to several hundred kHz.

The device uses pure tin-plated leads compliant with J-STD-002, meets UL 94V-0 flammability, and supports operation across –55 to +150 °C junction temperature range - critical for under-hood automotive and industrial power supplies.

FAQ

What is the maximum repetitive peak reverse voltage (VRRM) of the FR207G?

The FR207G has a VRRM rating of 1000 V, meaning it can block up to 1000 volts of reverse voltage repeatedly without breakdown. This makes the FR207G suitable for high-voltage rectification tasks such as in 800 V AC line inputs or 1000 V DC bus systems where safety margin and transient immunity are critical.

Does the FR207G have AEC-Q101 qualification?

The base FR207G is not AEC-Q101 qualified; however, the variant FR207GH (with "H" suffix) is explicitly qualified per AEC-Q101. The FR207G datasheet confirms that AEC-Q101 qualification applies only to parts marked with "H", and users requiring automotive-grade reliability must specify FR207GH for compliance.

What is the reverse recovery time (trr) of the FR207G and how does it affect circuit performance?

The FR207G has a reverse recovery time of 500 ns under standard test conditions (IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A). This value directly impacts switching loss and EMI in high-frequency converters - a 500 ns trr allows stable operation up to ~300 kHz while keeping snubber design manageable and conduction efficiency high in SMPS designs using the FR207G.

What package type does the FR207G use and what are its mechanical features?

The FR207G uses the DO-204AC (DO-15) axial-leaded package with glass-passivated chip junction, pure tin-plated leads compliant with J-STD-002, and UL 94V-0 rated molding compound. Its cathode band indicates polarity, and typical weight is 0.400 g - enabling reliable through-hole assembly and thermal performance with R_θJA = 70 °C/W.

How does the FR207G compare to the FR206G in terms of voltage rating and application scope?

The FR207G is rated for 1000 V VRRM, whereas the FR206G is rated for 800 V. This 200 V difference defines their system-level applicability: FR207G supports 800–1000 V DC bus systems (e.g., EV auxiliary supplies), while FR206G suits 600–800 V applications. Both share identical IF (2 A), IFSM (55 A), and DO-15 packaging, allowing direct substitution only when voltage margin permits.
