Product details
Overview
FR205G 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 55 A surge current capability; used in switching-mode power supplies and DC-DC converters requiring efficient unidirectional conduction.
For engineers reviewing the FR205G datasheet, FR205G pinout, FR205G application, or FR205G equivalent, key selection criteria include repetitive peak reverse voltage (600 V), thermal resistance (70 °C/W), junction temperature range (–55 to +150 °C), and AEC-Q101 qualification availability for automotive-grade variants.
Technical Context
The FR205G employs a glass-passivated single-die PN junction optimized for fast recovery in high-frequency switching applications. Its 250 ns trr and low 1.3 V VF at 2 A enable reduced switching losses in SMPS topologies operating up to several hundred kHz.
Thermal performance is defined by a junction-to-ambient resistance of 70 °C/W under standard PCB mounting conditions, with rated operation from –55 °C to +150 °C junction temperature and compliance with JESD201 Class 2 whisker testing for tin-plated leads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse blocking voltage; determines safe operating margin in 400–500 V DC bus applications |
| IF | 2 A - average forward current rating; defines continuous conduction capability at TA ≤ 75 °C with derating above |
| IFSM | 55 A - non-repetitive surge current (8.3 ms half-sine); supports inrush and transient overload handling |
| trr | 250 ns - reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables stable operation in 100–300 kHz switchers |
| VF (max) | 1.3 V at 2 A, 25 °C - forward voltage drop directly impacts conduction loss and thermal design in rectifier stage |
| RθJA | 70 °C/W - thermal resistance from junction to ambient; used to calculate junction temperature rise under real PCB layout conditions |
| IR (max) | 5 µA at 25 °C, 100 µA at 125 °C - leakage current limits reverse power loss and thermal runaway risk in high-temp environments |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, glass-passivated single-die rectifier with cathode band marking. Weight ≈ 0.400 g. Leads are pure tin-plated, solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., transformer secondary center-tap or switch node return path) |
| Cathode | Forward current exit point | Marked with band; connects to output rail or filter capacitor positive terminal; carries full load current |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery time | 250 ns - minimizes reverse recovery charge (Qrr) and associated switching losses in high-frequency converters |
| Low forward voltage | 1.3 V max at 2 A - reduces I²R conduction loss and improves efficiency in 12–48 V output SMPS stages |
| High surge capability | 55 A IFSM - withstands repeated cold-start surges and line transients without degradation |
| Glass passivation | Hermetic chip junction protection - ensures long-term reliability and moisture resistance in industrial environments |
| AEC-Q101 option | Available as FR205GH - qualified for automotive powertrain and body electronics per stress test requirements |

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; trr = 200 ns (slightly faster); VF = 1.25 V typ at 2 A; TO-220AC package | Requires heatsink for >1 A continuous use; not axial-leaded; incompatible with DO-15 footprint | Select when higher thermal dissipation is needed and board space permits TO-220 mounting |
| ON Semi MUR260 | 2 A / 600 V; trr = 35 ns (ultrafast); VF = 1.7 V max at 2 A; same DO-204AC package | Higher VF increases conduction loss; superior trr suits >500 kHz resonant topologies | Select when ultra-low Qrr is critical and 0.4 V higher VF is acceptable in thermal budget |
Compared with STTH2R06 and MUR260, the FR205G offers optimal balance of low VF, moderate trr, and axial DO-15 compatibility-making it ideal for cost-sensitive, space-constrained 100–300 kHz SMPS where thermal management relies on PCB copper area rather than discrete heatsinks.

FAQ
What is the maximum junction temperature rating for FR205G?
The FR205G has a maximum junction temperature (TJ MAX) of +150 °C and a minimum of –55 °C. This rating applies across its full operating range and is validated per JEDEC standards. Derating curves in the FR205G datasheet show allowable average forward current decreases linearly above +75 °C ambient, ensuring safe operation within the FR205G's thermal limits under real-world PCB conditions.
Is FR205G pin-compatible with other DO-204AC rectifiers like 1N4007?
No, FR205G is not functionally or electrically interchangeable with 1N4007 despite sharing the DO-204AC (DO-15) package. The FR205G is a fast recovery rectifier (250 ns trr, 600 V VRRM), while 1N4007 is a general-purpose silicon rectifier (30 µs trr, 1000 V VRRM). Substituting them risks excessive switching loss or failure in high-frequency circuits where FR205G is specified.
Does FR205G meet automotive qualification standards?
The base FR205G is not AEC-Q101 qualified, but the variant FR205GH is explicitly qualified per AEC-Q101 for automotive applications. FR205GH undergoes additional stress testing including temperature cycling, highly accelerated life testing (HALT), and mechanical shock per automotive requirements-making it suitable for under-hood and cabin power modules where FR205G alone would not be approved.
What is the reverse leakage current specification for FR205G at elevated temperature?
At 125 °C junction temperature and rated reverse voltage (600 V), the FR205G exhibits a maximum reverse leakage current (IR) of 100 µA. At 25 °C, IR is limited to 5 µA. These values are measured under pulsed conditions (30 ms PW) and reflect worst-case leakage behavior critical for standby power budgeting and thermal stability in sealed enclosures.
Can FR205G be used in surface-mount designs?
No, FR205G is an axial-leaded DO-204AC (DO-15) through-hole device and is not designed for surface-mount assembly. It requires plated-through holes and wave or selective soldering. For SMT equivalents, consider TSC's SOD-123 or SMA packages (e.g., TSF205G), which share identical electrical specs but differ in footprint, thermal path, and mounting method-FR205G itself must be mounted via through-hole process.
