Product details
Overview
FR103G R0G from Taiwan Semiconductor is a 1A, 200V fast recovery rectifier diode in DO-204AL (DO-41) package, featuring 150 ns reverse recovery time, 1.3 V max forward voltage at 1 A, and 30 A surge current capability. It serves as a primary-side output rectifier in switching-mode power supplies requiring high efficiency and thermal reliability.
For engineers reviewing the FR103G R0G datasheet, FR103G R0G pinout, FR103G R0G application, or FR103G R0G equivalent, key selection criteria include repetitive peak reverse voltage (200 V), junction-to-ambient thermal resistance (70 °C/W), glass-passivated junction construction, and AEC-Q101 qualification availability in related variants.
Technical Context
This discrete silicon rectifier uses a single-die, planar epitaxial structure with glass passivation for enhanced moisture and mechanical robustness. Its 150 ns trr enables operation in 50–200 kHz SMPS topologies while maintaining low switching losses.
The device operates across –55°C to +150°C junction temperature range, supports 1 A continuous forward current with derating above 25°C ambient, and exhibits only 5 µA max reverse leakage at 25°C - critical for standby power compliance in energy-efficient converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - maximum repetitive reverse blocking voltage; defines safe operating margin in 12–48 V DC-DC output stages |
| IF | 1 A - continuous average forward current; sets minimum heatsinking requirement for 12 W conduction-limited designs |
| trr | 150 ns - measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables efficient operation up to ~200 kHz switching frequency |
| VF (max) | 1.3 V @ 1 A, 25°C - directly determines conduction loss (1.3 W per diode at full load); impacts thermal design and efficiency |
| RθJA | 70 °C/W - junction-to-ambient thermal resistance in free-air; used to calculate max ambient temperature for 150°C TJ limit |
| IFSM | 30 A - non-repetitive surge rating (8.3 ms half-sine); withstands inrush and transient overloads without failure |
| IR (max) | 5 µA @ 25°C - low leakage preserves efficiency in high-impedance bias networks and standby circuits |
Pinout & Package
Package: DO-204AL (DO-41), axial lead, glass-passivated silicon die, cathode indicated by band. Weight: 0.340 g.
| Pin/Terminal | Circuit Role | Design Meaning |

Key Features
| Feature | Design Value |

| Low VF (≤1.3 V) | Reduces conduction loss by ≥15% vs. standard recovery diodes at 1 A, improving full-load efficiency in 12–24 V outputs |
| 150 ns trr | Minimizes reverse recovery charge (Qrr), lowering EMI and switching loss in flyback and forward converter secondary rectification |
| AEC-Q101 qualified option (FR103GH) | Validated for automotive under-hood applications including body control modules and infotainment power rails |
| RoHS & halogen-free | Complies with IEC 61249-2-21; supports green manufacturing and end-of-life recycling 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 |
|---|---|---|---|
| STTH1R02U | 1 A, 200 V, 120 ns trr, TO-220AC package (vs. DO-41); VF = 1.15 V typ | Higher power dissipation capability due to larger package; requires PCB footprint change and heatsink mounting | Select when higher thermal margin or >1 A pulsed current is required; not drop-in compatible |
| ON Semiconductor MUR120 | 1 A, 200 V, 75 ns trr, DO-41 package; VF = 1.25 V max; RoHS compliant | Superior speed enables >300 kHz operation; tighter VF distribution improves batch consistency in production | Preferred for high-frequency PFC front-ends or noise-sensitive audio power supplies |
Compared with STTH1R02U and MUR120, FR103G R0G offers optimal balance of cost, DO-41 compatibility, and 150 ns trr for mainstream 100–200 kHz SMPS - making it ideal for space-constrained consumer and industrial adapters where thermal headroom is moderate.

FAQ
What is the maximum junction temperature rating for FR103G R0G?
The FR103G R0G has a maximum junction temperature (TJ MAX) of +150°C, verified per absolute maximum ratings table. This allows operation in high-ambient environments such as enclosed power supplies or automotive under-dash locations. Derating begins at 25°C ambient, and thermal design must ensure junction temperature remains ≤150°C under worst-case load and airflow conditions. The FR103G R0G's 70 °C/W RθJA value is used to calculate allowable ambient temperature rise.
Is FR103G R0G AEC-Q101 qualified?
No, FR103G R0G is not AEC-Q101 qualified. However, the pin-compatible variant FR103GH (same DO-41 package, identical electrical specs) is AEC-Q101 qualified and listed in the ordering information. FR103G R0G shares the same glass-passivated die and construction but lacks the extended stress testing required for automotive qualification. For automotive applications, FR103G R0G should be replaced with FR103GH.
What does the 'R0G' suffix indicate in FR103G R0G?
The 'R0G' suffix in FR103G R0G denotes Taiwan Semiconductor's internal tape-and-reel packaging code: 'R0' specifies 5,000 units per reel, and 'G' indicates green molding compound compliant with RoHS and halogen-free standards (IEC 61249-2-21). This matches the 'FR1xG' ordering code defined in the datasheet's Ordering Information section. FR103G R0G is functionally identical to FR103G.
Can FR103G R0G replace FR102G in an existing design?
Yes, FR103G R0G can directly replace FR102G in most cases because both share identical package (DO-41), forward current (1 A), surge rating (30 A), and thermal characteristics. The only difference is VRRM: FR102G is rated for 100 V, while FR103G R0G is rated for 200 V. Substituting FR103G R0G provides increased reverse voltage margin without affecting layout, soldering, or thermal design - provided the higher rating is acceptable for the circuit's reverse stress profile.
What is the reverse recovery time (trr) test condition for FR103G R0G?
The reverse recovery time (trr) of 150 ns for FR103G R0G is measured under the specific condition: IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the Electrical Specifications table. This reflects real-world switching behavior in flyback and forward converters. The test uses a half-sine waveform with defined di/dt and voltage slew rate, and results are valid only at TA = 25°C unless otherwise noted. FR103G R0G's trr remains stable across its full operating temperature range.
