Product details
Overview
FR101GH from Taiwan Semiconductor is a 1A, 50V fast recovery rectifier diode in DO-204AL (DO-41) package, featuring 150ns reverse recovery time, 1.3V max forward voltage at 1A, and AEC-Q101 qualification for automotive-grade reliability. It serves as a primary output rectifier in low-voltage DC-DC converters requiring high efficiency and surge robustness.
For engineers reviewing the FR101GH datasheet, FR101GH pinout, FR101GH application, or FR101GH equivalent, key selection criteria include its 50V VRRM rating, 30A IFSM surge capability, AEC-Q101 compliance status, thermal resistance of 70°C/W, and DO-41 mechanical compatibility with standard through-hole layouts.
Technical Context
This device is a single-die, glass-passivated silicon junction rectifier optimized for switching-mode power supplies operating below 50V input/output rails. Its fast recovery (trr ≤ 150ns) minimizes switching losses during turn-off, while low VF (≤1.3V @ 1A) reduces conduction loss under continuous load.
The FR101GH operates across –55°C to +150°C junction temperature range and delivers stable reverse leakage (<5µA @ 25°C, <100µA @ 125°C) under rated VR. Its 10pF junction capacitance supports high-frequency operation without excessive capacitive loading on gate drivers or control circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse voltage; defines safe blocking capability in 50V-rated DC-DC outputs. |
| IF | 1 A - Continuous forward current rating; supports steady-state loads up to 1A without derating at 25°C ambient. |
| IFSM | 30 A - Non-repetitive surge current (8.3ms half-sine); withstands startup inrush or transient overloads. |
| trr | 150 ns - Reverse recovery time; enables efficient operation in 100–500 kHz SMPS topologies with minimal switching loss. |
| VF | 1.3 V max @ 1A, 25°C - Forward voltage drop; determines conduction loss (1.3W max at 1A), critical for thermal design. |
| RθJA | 70 °C/W - Junction-to-ambient thermal resistance; used to calculate junction temperature rise in PCB-mounted applications. |
| IR | 5 µA max @ 25°C - Reverse leakage current; ensures low standby power loss in always-on converter stages. |
Pinout & Package
Package: DO-204AL (DO-41), axial-leaded, glass-passivated, RoHS-compliant, halogen-free molding compound (IEC 61249-2-21), cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to lower-potential node (e.g., switch node or ground return) in flyback/freewheeling paths. |
| Cathode (Lead 2, banded end) | Forward current exit / reverse blocking terminal | Connected to positive output rail; blocks reverse voltage up to 50V and conducts forward current when anode > cathode by ≥0.7V. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics per stress test requirements (HTOL, TC, HTRB, etc.), enabling use in engine control, body electronics, and ADAS power rails. |
| Glass passivated junction | Enhances moisture resistance and long-term reliability under humid or thermally cycled conditions, reducing risk of parametric drift. |
| Low VF (≤1.3V) | Reduces power dissipation by ~20% vs. standard 1N400x series at 1A, lowering heatsink requirements in space-constrained designs. |
| High IFSM (30A) | Survives repeated cold-start surges in automotive DC-DC modules without degradation, supporting robust system-level fault tolerance. |
| DO-41 mechanical standardization | Enables direct replacement in legacy through-hole designs using industry-standard footprint and soldering profiles (J-STD-002 compliant). |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06U | Same 1A/600V rating but higher VF (1.7V typ), slower trr (200ns), TO-220AC package | Designed for higher-voltage industrial SMPS; unsuitable for 50V systems due to over-spec'd VRRM and larger footprint | Select FR101GH for cost-sensitive, space-constrained 50V designs where low VF and DO-41 fit are mandatory. |
| ON Semi MUR105G | 50V VRRM, 1A IF, 100ns trr, same DO-41 package, but not AEC-Q101 qualified | Lacks automotive qualification; suitable for commercial/industrial use only; slightly faster recovery but higher VF (1.4V max) | Choose FR101GH when AEC-Q101 compliance is required; choose MUR105G only if trr <150ns is critical and automotive use is excluded. |
Compared with STTH1R06U and MUR105G, the FR101GH uniquely combines AEC-Q101 qualification, 50V-specific optimization, and DO-41 compatibility-making it the only choice for automotive 12V-system rectification where footprint, reliability, and regulatory alignment are jointly constrained.

FAQ
What is the maximum junction temperature rating for FR101GH?
The FR101GH has a maximum junction temperature (TJ MAX) of +150°C, verified per JEDEC JESD22-A108. This rating enables operation in under-hood automotive environments and enclosed industrial enclosures. Derating curves in the FR101GH datasheet specify that continuous forward current must be reduced linearly above 25°C ambient to maintain TJ ≤ 150°C, with RθJA = 70°C/W used for thermal calculation. The FR101GH maintains full electrical performance within this range.
Is FR101GH pin-compatible with standard 1N400x series diodes?
No, FR101GH is not pin-compatible with 1N400x diodes despite sharing the DO-41 package outline. While both use DO-204AL (DO-41) mechanical form factor, the FR101GH is a fast recovery rectifier (trr ≤ 150ns) versus the 1N400x's general-purpose slow recovery (trr ≥ 30µs). Electrical behavior differs significantly: FR101GH exhibits lower VF and higher IR sensitivity, making direct substitution unsafe in circuits relying on slow reverse recovery for snubbing or EMI control. Always verify layout and schematic compatibility before replacing 1N400x with FR101GH.
Does FR101GH support lead-free soldering processes?
Yes, FR101GH features pure tin-plated leads compliant with J-STD-002 for solderability and fully compatible with lead-free reflow (up to 260°C peak) and wave soldering processes. Its molding compound meets UL 94V-0 flammability rating and is halogen-free per IEC 61249-2-21. The FR101GH has been qualified for Pb-free assembly without delamination or intermetallic growth issues, and no special pre-bake or moisture sensitivity level (MSL) handling is required.
What does the "H" suffix in FR101GH signify?
Per Taiwan Semiconductor's ordering information, the "H" suffix in FR101GH denotes AEC-Q101 qualification - a rigorous stress-test certification for discrete semiconductors used in automotive electronics. This includes HTOL (high-temperature operating life), temperature cycling, HTRB (high-temperature reverse bias), and ESD testing per AEC standards. The FR101GH is not merely "automotive grade" - it is fully documented and tested to AEC-Q101 Rev D, distinguishing it from non-H variants like FR101G which lack this qualification.
Can FR101GH be used in place of FR102GH in a 100V design?
No, FR101GH must not be substituted for FR102GH in a 100V design. The FR101GH has a maximum repetitive reverse voltage (VRRM) of 50V, while FR102GH is rated for 100V. Operating FR101GH at 100V reverse bias risks catastrophic avalanche breakdown, permanent junction damage, and field failure. The "x" digit in FR10xG directly maps to voltage grade (1=50V, 2=100V, etc.), and these ratings are not interchangeable. Always match the "x" digit to the circuit's peak reverse voltage requirement - FR101GH is strictly for ≤50V applications.
