Product details
Overview
FR205G A0G 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 2A, and 55 A surge current capability; used in switching mode power supplies and DC-DC converters.
For engineers reviewing the FR205G A0G datasheet, FR205G A0G pinout, FR205G A0G application, or FR205G A0G equivalent, key selection criteria include VRRM = 600 V, trr = 250 ns, VF ≤ 1.3 V @ 2A, IFSM = 55 A, and DO-15 mechanical compatibility with standard through-hole PCB layouts.
Technical Context
This single-die, glass-passivated fast recovery rectifier operates with junction temperatures up to +150°C and supports repetitive peak reverse voltages of 600 V. Its low VF and 250 ns trr enable high-efficiency operation in high-frequency switching topologies.
The device exhibits 5 µA max reverse leakage at 25°C and 100 µA at 125°C, with 10 pF typical junction capacitance at 4 V reverse bias and 1 MHz - critical for minimizing switching losses and EMI in SMPS designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - maximum repetitive reverse blocking voltage; defines safe operating range in bridge or flyback configurations |
| IF | 2 A continuous average forward current - determines thermal design margin under steady-state conduction |
| trr | 250 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; directly impacts switching loss and RFI generation |
| VF | ≤1.3 V @ 2 A, 25°C - sets conduction loss and thermal load in high-duty-cycle applications |
| IFSM | 55 A - non-repetitive surge rating for startup/inrush tolerance without failure |
| RθJA | 70 °C/W - junction-to-ambient thermal resistance; guides heatsinking requirements for 2 A operation |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, glass-passivated silicon die, cathode indicated by band. Leads are pure tin plated, solderable per J-STD-002, UL 94V-0 molded compound.
| 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) |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band; ties to output rail or filter capacitor positive; blocks 600 V reverse |
Key Features
| Feature | Design Value |
|---|---|
| Fast recovery time | 250 ns - reduces switching loss and improves efficiency in 50–500 kHz SMPS |
| Glass passivated junction | Enhances moisture resistance and long-term reliability in humid industrial environments |
| Low forward voltage | ≤1.3 V @ 2 A - lowers conduction loss vs. standard rectifiers, easing thermal management |
| AEC-Q101 qualified option available | FR205GH variant meets automotive stress test requirements; FR205G A0G is industrial-grade |

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 | VRRM = 600 V, trr = 110 ns, VF = 1.7 V @ 2 A - faster but higher VF | Better for >200 kHz designs; higher conduction loss limits use in thermally constrained spaces | Prefer when switching speed dominates over thermal budget |
| ES2D | VRRM = 200 V, trr = 35 ns, IF = 2 A - lower voltage rating, much faster | Not suitable for 600 V bus applications; limited to low-voltage DC-DC outputs | Select only if system VR does not exceed 200 V and ultra-fast recovery is required |
Compared with STTH2R06 and ES2D, FR205G A0G delivers optimal balance of 600 V blocking, 250 ns recovery, and 1.3 V VF for cost-sensitive 50–100 kHz industrial power supplies where thermal and voltage margins are prioritized over minimum trr.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for FR205G A0G?
The FR205G A0G has a VRRM rating of 600 V, meaning it can reliably block up to 600 V of reverse voltage in repetitive operation. This value is fixed per the FR205G designation in the FR201G–FR207G family and is confirmed in the absolute maximum ratings table. Exceeding this voltage risks avalanche breakdown and permanent damage to the FR205G A0G.
Is FR205G A0G RoHS and halogen-free compliant?
Yes, FR205G A0G is RoHS compliant and halogen-free per IEC 61249-2-21. The device uses green molding compound and pure tin-plated leads, meeting both environmental directives without compromising solderability or long-term reliability. This compliance applies to the standard FR205G A0G variant, not contingent on special ordering codes.
What is the reverse recovery time (trr) specification for FR205G A0G?
The FR205G A0G has a reverse recovery time (trr) of 250 ns, tested under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This value is explicitly assigned to FR205G in the electrical specifications table and distinguishes it from adjacent variants (e.g., FR204G = 150 ns, FR206G = 500 ns). It directly affects switching loss in high-frequency power circuits using the FR205G A0G.
Does FR205G A0G have AEC-Q101 qualification?
No, FR205G A0G is not AEC-Q101 qualified. The AEC-Q101 version is designated FR205GH (with 'H' suffix), which undergoes additional automotive stress testing. FR205G A0G is rated for industrial temperature range (−55°C to +150°C) and intended for commercial/industrial applications - not automotive systems requiring AEC-Q101 certification.
What packaging options are available for FR205G A0G?
FR205G A0G is supplied in 1,500-piece ammo boxes, as indicated by the 'A0G' suffix in the ordering code. This contrasts with the tape-and-reel option (FR205G), which ships in 3,500-piece reels. Both share identical DO-204AC (DO-15) packaging, pinout, and electrical specifications - only the packing method differs for FR205G A0G.
