Product details

Overview

FR207G-T 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 switching mode power supplies and DC-DC converters.

For engineers reviewing the FR207G-T datasheet, FR207G-T pinout, FR207G-T application, or FR207G-T equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (70 °C/W), junction temperature range (–55 to +150 °C), cathode-band polarity marking, and RoHS/halogen-free compliance for industrial power conversion designs.

Technical Context

This single-die fast recovery rectifier uses glass-passivated junction technology to achieve low forward voltage and high surge robustness. Its 1000 V V_RRM and 500 ns trr support high-frequency switching in off-line SMPS and PFC stages where voltage margin and recovery speed are critical.

Thermal performance is defined by R_θJA = 70 °C/W, enabling 2 A continuous conduction at ambient temperatures up to 85 °C with standard PCB copper area. Reverse leakage remains ≤100 µA at 125 °C, supporting stable operation in thermally constrained environments.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	1000 V - supports input rectification in universal AC mains (85–265 V_AC) with ≥2× safety margin
I_F	2 A continuous - suitable for mid-power adapters and auxiliary rails without forced cooling
I_FSM	55 A (8.3 ms half-sine) - withstands cold-start surges and transient overloads
t_rr	500 ns - reduces switching losses and EMI in 50–100 kHz SMPS topologies
V_F max	1.3 V @ 2 A, 25 °C - lowers conduction loss vs. standard recovery diodes (~1.8–2.2 V)
R_θJA	70 °C/W - requires ≥1 cm² of 1 oz copper pad for thermal derating to full I_F
Junction temp	–55 to +150 °C - enables deployment in automotive under-hood or industrial control enclosures

Pinout & Package

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	600 V V_RRM, 50 ns t_rr, TO-220AC package	Limited to ≤600 V AC inputs; faster recovery but larger footprint and higher cost	Select when ultra-fast recovery (<100 ns) and higher surge tolerance are required, and board space allows TO-220 mounting
ES2J	600 V V_RRM, 35 ns t_rr, SMA package (2.5 mm × 4.5 mm)	Lower voltage rating and surface-mount form factor; not drop-in for through-hole DO-15 layouts	Choose for compact SMT designs operating ≤265 V_AC where automated assembly and minimal board area are priorities

Compared with STTH2R06 and ES2J, the FR207G-T uniquely balances 1000 V blocking capability, 500 ns recovery, and axial DO-15 packaging-making it optimal for cost-sensitive, through-hole, high-input-voltage power supplies where moderate speed suffices and lead-forming flexibility is needed.

FAQ

What is the maximum repetitive peak reverse voltage rating for FR207G-T?

The FR207G-T has a maximum repetitive peak reverse voltage (V_RRM) of 1000 V, verified per Taiwan Semiconductor's B2105 datasheet. This rating enables use in 230 V_AC and 400 V DC bus applications with sufficient safety margin. The FR207G-T must not be operated above this voltage under any steady-state or transient condition to prevent avalanche breakdown or catastrophic failure.

Does FR207G-T have a specified reverse recovery time, and how is it measured?

Yes, the FR207G-T has a reverse recovery time (t_rr) of 500 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the official datasheet. This value applies specifically to the FR206G-T and FR207G-T variants and reflects performance at room temperature; t_rr increases slightly at elevated junction temperatures.

What package type and lead finish does FR207G-T use?

The FR207G-T uses the DO-204AC (DO-15) axial-leaded package with pure tin-plated leads compliant with J-STD-002 for solderability. The case meets UL 94V-0 flammability rating, and polarity is indicated by a visible cathode band on the body-critical for correct orientation during manual or wave soldering.

Is FR207G-T RoHS and halogen-free compliant?

Yes, the FR207G-T is RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. These certifications are confirmed in the B2105 datasheet revision and apply to the entire FR20xG-T family, including the FR207G-T, ensuring environmental compliance for export and end-product certification.

What is the thermal resistance from junction to ambient for FR207G-T?

The junction-to-ambient thermal resistance (R_θJA) of FR207G-T is 70 °C/W, measured on a standard JEDEC test board (1 in² copper area). This value assumes no additional heatsinking; actual thermal performance improves with increased copper area or airflow, and derating curves in the datasheet define safe I_F limits versus ambient temperature.
