Product details
Overview
FR103GH 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 AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the FR103GH datasheet, FR103GH pinout, FR103GH application, or FR103GH equivalent, key selection criteria include repetitive peak reverse voltage (200 V), surge current capability (30 A), junction temperature range (–55°C to +150°C), thermal resistance (70°C/W), and RoHS/halogen-free compliance.
Technical Context
This device is a single-die, glass-passivated silicon junction rectifier optimized for high-efficiency switching-mode power supplies. Its fast recovery (trr = 150 ns) minimizes switching losses during turn-off, while low VF (≤1.3 V) reduces conduction loss at 1 A DC forward current.
The FR103GH operates across –55°C to +150°C junction temperature and exhibits low leakage (≤5 µA at 25°C, ≤100 µA at 125°C under rated VR), supporting stable performance in thermally demanding environments such as automotive engine compartments and industrial converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse voltage the diode blocks without breakdown; defines usable input voltage headroom in DC-DC stages. |
| IF | 1 A - Continuous average forward current rating; determines steady-state power handling in rectification paths. |
| IFSM | 30 A - Non-repetitive surge current (8.3 ms half-sine); supports inrush and transient overload tolerance. |
| trr | 150 ns - Reverse recovery time; enables efficient operation up to ~1 MHz switching frequencies in SMPS. |
| VF (max) | 1.3 V @ 1 A, 25°C - Forward voltage drop; directly impacts conduction loss (P = IF × VF) and thermal design margin. |
| TJ max | +150°C - Maximum allowable junction temperature; sets thermal derating limits and heatsink requirements. |
| RθJA | 70°C/W - Junction-to-ambient thermal resistance; used with power dissipation to estimate temperature rise on PCB without heatsink. |
Pinout & Package
Package: DO-204AL (DO-41), axial leaded, glass-passivated chip, cathode indicated by band. Weight: 0.340 g.

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, trr = 100 ns, TO-220AC package (larger, higher thermal mass) | Preferred where board space allows and higher thermal dissipation is needed; not DO-41 drop-in | Select when RθJA < 50°C/W is required and axial leads are not mandatory. |
| ES1D-E3/57T | 1 A, 200 V, trr = 35 ns, SMD SMB package, VF = 1.7 V (higher) | Suitable for automated SMT assembly; lower trr but higher conduction loss than FR103GH | Choose for high-volume production with reflow capability and tighter layout constraints. |
Compared with STTH1R02U and ES1D-E3/57T, the FR103GH offers the optimal balance of axial DO-41 compatibility, AEC-Q101 qualification, and 150 ns trr with low VF-making it ideal for cost-sensitive, through-hole automotive and industrial power designs where thermal and footprint constraints are moderate.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) rating for FR103GH?
The FR103GH has a VRRM rating of 200 V, meaning it reliably blocks up to 200 V of repetitive reverse voltage without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version H2104) and defines its safe operating range in rectifier circuits with up to 200 V reverse bias, such as 120 VAC-derived DC rails or 24 V boost outputs. Exceeding this voltage risks avalanche failure.
Is FR103GH AEC-Q101 qualified, and what does that entail for automotive use?
Yes, FR103GH is AEC-Q101 qualified, as explicitly stated in the Ordering Information section (suffix "H") and Features list. This qualification validates the device for automotive applications through stress testing-including temperature cycling, humidity bias HAST, and mechanical shock-ensuring reliability in engine control units, lighting modules, and infotainment systems. The FR103GH's –55°C to +150°C TJ range and glass passivation further support under-hood deployment.
What is the reverse recovery time (trr) of FR103GH, and how does it affect switching performance?
The FR103GH has a reverse recovery time (trr) of 150 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This fast trr minimizes switching losses during turn-off transitions in high-frequency converters (e.g., >100 kHz flyback or forward topologies), reducing heat generation and enabling higher efficiency than standard recovery diodes like the 1N4007 (trr > 2 µs). It is critical for maintaining EMI compliance and thermal stability.
Does FR103GH have a specified forward voltage (VF), and what is its typical value?
Yes, FR103GH specifies a maximum forward voltage (VF) of 1.3 V at IF = 1 A and TJ = 25°C. This value is measured under pulsed conditions (PW = 0.3 ms) and represents worst-case conduction loss. In practice, VF decreases slightly at lower currents and increases with junction temperature-enabling accurate thermal modeling and efficiency estimation in real-world 1 A rectifier designs.
What package type and lead finish does FR103GH use, and why does it matter?
FR103GH uses the DO-204AL (DO-41) axial package with pure tin-plated leads compliant with J-STD-002 solderability standards. This package enables manual or wave soldering in legacy through-hole assemblies and provides robust mechanical anchoring in vibration-prone environments like automotive chassis. The tin plating ensures reliable wetting and intermetallic formation, while the glass passivation protects the die from environmental degradation over time.
