Product details
Overview
FR203G R0G from Taiwan Semiconductor is a 2A, 200V fast recovery rectifier diode in DO-204AC (DO-15) package, featuring 150 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.
For engineers reviewing the FR203G R0G datasheet, FR203G R0G pinout, FR203G R0G application, or FR203G R0G equivalent, key selection criteria include repetitive peak reverse voltage (200 V), thermal resistance (70 °C/W), junction temperature range (–55 to +150 °C), and AEC-Q101 qualification status where applicable.
Technical Context
This device is a single-die, glass-passivated silicon junction rectifier optimized for high-efficiency switching applications. Its fast recovery (trr = 150 ns) minimizes switching losses during turn-off in high-frequency converters.
The DO-204AC package provides robust mechanical reliability with pure tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance; polarity is marked by cathode band.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse voltage the device blocks without breakdown |
| IF | 2 A - continuous average forward current rating at TA = 75°C |
| IFSM | 55 A - non-repetitive peak surge current (8.3 ms half-sine) the device withstands |
| trr | 150 ns - reverse recovery time under IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A |
| VF | ≤1.3 V - maximum forward voltage drop at 2 A and TJ = 25°C, directly impacting conduction loss |
| RθJA | 70 °C/W - junction-to-ambient thermal resistance, critical for heatsinking design in enclosed environments |
Pinout & Package
Package: DO-204AC (DO-15), axial leaded, glass-passivated, cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit; must handle full load current and surge transients |
| Cathode | Forward current exit point / reverse blocking terminal | Marked by band; connected to higher-potential node; sustains up to 200 V reverse bias |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R02 | Same 2 A / 200 V rating; trr = 35 ns (faster), VF = 1.15 V (lower), DO-204AL (DO-41) package | Higher switching efficiency in >100 kHz designs; smaller footprint but lower surge rating (IFSM = 45 A) | Select when faster recovery and lower VF outweigh need for 55 A surge margin |
| 1N5622 | 2 A / 200 V; trr = 250 ns (slower), VF = 1.3 V, DO-204AC package, no AEC-Q101 option | Lower cost for non-automotive industrial use; less suitable for high-frequency or automotive-critical designs | Select for cost-sensitive, non-automotive applications where 150 ns trr is not required |
Compared with STTH2R02 and 1N5622, the FR203G R0G offers balanced performance: superior surge robustness (55 A) over STTH2R02 and faster recovery than 1N5622, while maintaining DO-204AC compatibility and optional AEC-Q101 qualification.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for FR203G R0G?
The FR203G R0G has a VRRM rating of 200 V. This means it can reliably block up to 200 volts of reverse-biased voltage in repetitive operation without breakdown. This value is fixed per the FR203G designation in the FR201G–FR207G family and is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version H2105).
Does FR203G R0G have AEC-Q101 qualification?
The base FR203G R0G variant is not AEC-Q101 qualified; however, the FR203GH variant (with "H" suffix) is explicitly qualified per AEC-Q101. The R0G suffix indicates standard industrial grade. Engineers requiring automotive qualification must specify FR203GH - the FR203G R0G itself does not carry this certification.
What is the reverse recovery time (trr) of FR203G R0G and how is it measured?
The FR203G R0G has a reverse recovery time (trr) of 150 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter reflects the time required for the diode to transition from forward conduction to reverse blocking state, directly affecting switching losses in high-frequency circuits like SMPS using the FR203G R0G.
What package type does FR203G R0G use and what are its key mechanical features?
The FR203G R0G uses the DO-204AC (DO-15) axial package. Key mechanical features include glass passivation for junction protection, pure tin-plated leads compliant with J-STD-002, UL 94V-0 molding compound, and cathode polarity indicated by a visible band. Its weight is approximately 0.400 g.
How does the thermal performance of FR203G R0G impact PCB layout?
The FR203G R0G has a junction-to-ambient thermal resistance (RθJA) of 70 °C/W, meaning each watt of dissipated power raises the junction temperature by 70 °C above ambient. To maintain TJ ≤ 150 °C, PCB layout must provide adequate copper area and airflow - especially critical when operating near 2 A continuous current where VF-induced losses approach 2.6 W.
