Product details
Overview
FR101G R1G from Taiwan Semiconductor is a 1A, 50V fast recovery rectifier diode in DO-204AL (DO-41) package, featuring 1.3V max forward voltage at 1A, 30A surge current capability, and 150°C maximum junction temperature - used in DC-DC converters and switching-mode power supplies.
For engineers reviewing the FR101G R1G datasheet, FR101G R1G pinout, FR101G R1G application, or FR101G R1G equivalent, key selection criteria include repetitive peak reverse voltage (50V), thermal resistance (70°C/W), reverse recovery time (150ns), RoHS/halogen-free compliance, and AEC-Q101 qualification status.
Technical Context
The FR101G R1G employs a glass-passivated silicon junction for enhanced reliability and moisture resistance. Its single-die construction supports high surge current (30A, 8.3ms half-sine) and low conduction loss with VF ≤1.3V at 1A/25°C.
Designed for high-efficiency switching applications, it delivers 150ns reverse recovery time under IF = 0.5A / IR = 1.0A / Irr = 0.25A test conditions and exhibits only 5µA max reverse leakage at 25°C and rated VR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Avg) | 1 A - continuous forward current rating defines maximum steady-state power handling in rectification paths |
| VRRM | 50 V - peak reverse blocking voltage determines minimum isolation margin in 24–48V DC-DC stages |
| IFSM | 30 A - non-repetitive surge current capacity enables robustness against startup transients and load dumps |
| trr | 150 ns - fast recovery time minimizes switching losses and EMI in 50–500 kHz SMPS designs |
| RθJA | 70 °C/W - junction-to-ambient thermal resistance sets heatsinking requirements for ambient temperatures up to 75°C |
| VF @ 1A | ≤1.3 V - low forward voltage reduces conduction loss and improves efficiency in high-duty-cycle operation |
| IR @ 25°C | ≤5 µA - low reverse leakage preserves voltage hold-up and prevents standby power waste |
Pinout & Package
Package: DO-204AL (DO-41), axial leaded, glass-passivated, cathode indicated by band. Weight: 0.340 g. UL 94V-0 molding compound, pure tin-plated leads compliant with J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., transformer secondary or switch node) in half-wave or full-wave rectifier configurations |
| Cathode | Forward current exit / reverse blocking terminal | Marked with band; ties to output capacitor positive or filter inductor input - defines polarity-sensitive placement on PCB |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable long-term performance in humid or thermally cycled environments without encapsulation degradation |
| AEC-Q101 qualified option (FR101GH) | Validated for automotive under-hood applications requiring stress testing per JEDEC standards |
| RoHS & halogen-free (IEC 61249-2-21) | Meets global environmental compliance mandates for industrial and consumer end equipment |
| Junction capacitance (10 pF @ 1 MHz, 4 V) | Minimizes high-frequency displacement current and noise coupling in fast-switching topologies |
| JESD 201 Class 2 whisker resistance | Ensures solder joint integrity over time in vibration-prone or high-reliability deployments |
Applications
| AC-DC Adapter Power Supply | Automotive Body Control Module (BCM) |
|---|---|

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 | 600V VRRM, 1.7V VF @ 1A, TO-220AC package | Higher voltage rating but higher VF and larger footprint - suited for universal-input PFC front-ends | Select when >100V reverse blocking is required; not drop-in due to package and VF mismatch |
| ON Semi MUR105 | 50V VRRM, 1.25V VF @ 1A, DO-41, 100ns trr | Faster recovery (100ns vs. 150ns) and slightly lower VF - optimized for higher-frequency SMPS | Preferred for >300 kHz designs where reduced switching loss outweighs minor cost increase |
Compared with STTH1R06U and MUR105, the FR101G R1G offers optimal balance of low VF, proven DO-41 manufacturability, and AEC-Q101 availability - making it ideal for cost-sensitive, medium-frequency 50V rectification where thermal and space constraints favor axial-leaded solutions.

FAQ
What is the maximum junction temperature rating for FR101G R1G?
The FR101G R1G has a maximum junction temperature (TJ) rating of +150°C, validated per JEDEC JESD22-A108. This allows reliable operation in high-ambient environments such as enclosed power supplies or under-hood automotive modules when paired with appropriate thermal design. Derating curves in the FR101G R1G datasheet specify usable current limits above 75°C ambient.
Is FR101G R1G RoHS and halogen-free compliant?
Yes, the FR101G R1G is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and the pure tin-plated leads meet J-STD-002 solderability requirements. Compliance documentation is available upon request for FR101G R1G.
What does the "R1G" suffix indicate in FR101G R1G?
The "R1G" suffix in FR101G R1G denotes Taiwan Semiconductor's standard packaging and marking variant: "R" indicates tape-and-reel packaging (5,000 pcs/reel), and "G" signifies green (halogen-free) compound. It is functionally identical to FR101G in electrical and thermal specifications - the suffix reflects packaging and environmental attributes, not device revision.
How does FR101G R1G compare to FR102G in terms of reverse voltage rating?
The FR101G R1G is rated for 50V repetitive peak reverse voltage (VRRM), while FR102G is rated for 100V VRRM. Both share identical forward characteristics (1A IF, 30A IFSM, 150°C TJ), package (DO-41), and recovery time (150ns). Select FR101G R1G only for circuits where reverse voltage remains ≤50V - exceeding this risks avalanche breakdown and premature failure.
Does FR101G R1G have AEC-Q101 qualification?
The base FR101G R1G is not AEC-Q101 qualified; however, the FR101GH variant (same electrical specs, "H" suffix) is fully AEC-Q101 qualified per Rev H2104 documentation. For automotive applications requiring stress-tested reliability, specify FR101GH - FR101G R1G remains suitable for industrial and consumer power supplies where qualification is not mandated.
