Product details
Overview
FR203GH 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 forward voltage at 2 A, and 55 A surge current capability. It serves as the primary output rectifier in high-frequency switching power supplies for industrial DC-DC converters.
For engineers reviewing the FR203GH datasheet, FR203GH pinout, FR203GH application, or FR203GH equivalent, key selection criteria include its AEC-Q101 qualification, glass-passivated junction, low VF/low trr trade-off, and DO-15 mechanical compatibility with legacy through-hole layouts.
Technical Context
This device employs a single-die silicon PN junction with glass passivation to ensure stable leakage performance across temperature and long-term reliability under repetitive surge stress. Its 150 ns trr enables operation in 50–200 kHz SMPS topologies without excessive switching loss.
The FR203GH is rated for 200 V repetitive peak reverse voltage (VRRM), supports 2 A average forward current (IF), and maintains ≤5 µA reverse leakage at 25°C - critical for maintaining efficiency in low-power standby stages of AC-DC adapters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum blocking voltage before avalanche conduction begins |
| IF | 2 A - continuous average forward current at 75°C case temperature |
| IFSM | 55 A - non-repetitive surge current handling for 8.3 ms half-sine, enabling robust startup/short-circuit tolerance |
| trr | 150 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; defines minimum switching frequency limit |
| VF | 1.3 V max at IF = 2 A, TJ = 25°C - directly determines conduction loss in output stage |
| IR | 5 µA max at VR = 200 V, TJ = 25°C - impacts no-load power consumption and thermal runaway risk |
| RθJA | 70 °C/W - junction-to-ambient thermal resistance in free-air, defining heatsinking requirements |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, glass-passivated, RoHS- and halogen-free compliant. Cathode indicated by band on body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead 1) | Forward current entry point | Connected to transformer secondary or switch node; must withstand 55 A surge transients |
| Cathode (lead 2) | Forward current exit / reverse blocking terminal | Connected to output capacitor; polarity band ensures correct orientation in PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade temperature cycling, humidity, and mechanical shock per JESD22 standards |
| Glass passivated junction | Eliminates surface contamination sensitivity, ensuring stable IR over 10-year field life |
| Low VF (1.3 V max) | Reduces conduction loss by ~15% vs. standard recovery diodes at 2 A, improving full-load efficiency |
| Fast trr (150 ns) | Enables higher switching frequencies without excessive EMI or diode-induced ringing in flyback outputs |
| DO-15 mechanical compatibility | Direct replacement for legacy 1N400x and FR10x series in existing through-hole designs |

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 | 2 A, 200 V, 120 ns trr, TO-220AC package | Requires PCB rework for surface-mount or larger footprint; higher thermal mass | Preferred where board space permits and lower trr justifies SMT transition |
| ON Semi MUR220 | 2 A, 200 V, 35 ns trr, DO-15 package, no AEC-Q101 | Lacks automotive qualification; tighter trr spec but higher VF (1.7 V) | Used in cost-sensitive consumer power supplies where AEC-Q101 is not required |
Compared with STTH2R02 and MUR220, the FR203GH uniquely combines AEC-Q101 compliance, DO-15 through-hole compatibility, and balanced trr/VF performance - making it optimal for industrial and automotive retrofit designs requiring zero layout change and validated reliability.

FAQ
What is the maximum junction temperature rating for FR203GH?
The FR203GH has a maximum junction temperature (TJ MAX) of +150°C, verified per JEDEC JESD22-A108. This rating allows operation in sealed enclosures up to 105°C ambient when derated per the forward current derating curve. The FR203GH maintains specified electrical parameters within this range, including stable VF and IR behavior.
Is FR203GH pin-compatible with standard DO-15 rectifiers like 1N4007?
Yes, the FR203GH uses the DO-204AC (DO-15) package with identical lead spacing, diameter, and cathode band marking as 1N4007. However, unlike 1N4007, the FR203GH offers faster recovery (150 ns vs. >2 µs), lower VF (1.3 V vs. ~1.1 V at 1 A), and AEC-Q101 qualification - making it a functional upgrade, not a drop-in replacement for all applications.
Does FR203GH meet automotive qualification standards?
Yes, the "H" suffix in FR203GH explicitly denotes AEC-Q101 qualification per Rev H2105 documentation. This includes testing for temperature cycling, high-temperature operating life, unbiased highly accelerated stress test (uHAST), and mechanical shock - confirming suitability for under-hood and infotainment power applications.
What is the reverse recovery time (trr) test condition for FR203GH?
The FR203GH reverse recovery time is specified as 150 ns maximum under the condition: IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, per Figure 6 in the official datasheet. This test circuit uses a defined di/dt and clamping setup to replicate real-world switching node transitions in flyback and forward converters.
How does the glass passivation in FR203GH improve long-term reliability?
Glass passivation in the FR203GH forms a hermetic barrier over the silicon junction, preventing moisture ingress and metal ion migration that cause parametric drift or premature failure. This enables stable IR performance over 10+ years in humid or chemically aggressive environments - a key reason FR203GH is selected for industrial PLC power modules.
