Product details
Overview
FR107G from Taiwan Semiconductor is a 1A, 1000V fast recovery rectifier diode in DO-204AL (DO-41) package, featuring 500 ns reverse recovery time, 1.3 V max forward voltage at 1 A, and 30 A surge capability - deployed in high-efficiency DC-DC converters and industrial switching inverters.
For engineers reviewing the FR107G datasheet, FR107G pinout, FR107G application, or FR107G equivalent, key selection criteria include VRRM = 1000 V, IF = 1 A, trr = 500 ns, RθJA = 70 °C/W, and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
This discrete fast recovery rectifier uses a glass-passivated silicon junction to achieve low conduction loss and stable thermal performance up to 150 °C junction temperature. Its single-die configuration supports unidirectional current flow with cathode-band polarity marking and pure tin-plated leads compliant with J-STD-002 solderability.
The device operates under repetitive peak reverse voltages up to 1000 V and withstands 8.3 ms half-sine surge currents of 30 A. Reverse leakage remains ≤100 µA at 125 °C, enabling stable operation in thermally demanding power conversion stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - maximum blocking voltage before breakdown in reverse bias |
| IF | 1 A continuous - rated average forward current at 75 °C ambient |
| trr | 500 ns - critical for minimizing switching losses in 50–200 kHz SMPS designs |
| VF (max) | 1.3 V @ 1 A, 25 °C - directly impacts conduction loss and thermal rise in high-duty-cycle operation |
| RθJA | 70 °C/W - defines thermal derating slope; limits usable current in still-air PCB layouts |
| IFSM | 30 A @ 8.3 ms - supports startup surges and transient overload without failure |
| Junction temp | −55 °C to +150 °C - enables deployment in under-hood automotive and industrial environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1R06 | VRRM = 600 V, trr = 50 ns, VF = 1.15 V @ 1 A - faster but lower voltage rating | Suitable only where system peak reverse voltage ≤600 V; not for universal AC input | Select when ultra-low trr dominates over voltage margin, e.g., high-frequency resonant converters |
| ON Semi MUR110 | VRRM = 1000 V, trr = 75 ns, VF = 1.25 V @ 1 A - superior speed and slightly lower VF | Requires revalidation for AEC-Q101 use; no automotive qualification stated in datasheet | Prefer for non-automotive 1000 V applications needing faster recovery and tighter VF tolerance |
Compared with STTH1R06 and MUR110, FR107G trades speed for higher voltage margin and automotive qualification - making it optimal for cost-sensitive, high-reliability 1000 V rectification where 500 ns trr suffices and AEC-Q101 compliance is mandatory.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for FR107G?
The FR107G has a VRRM of 1000 V, verified per Taiwan Semiconductor's H2104 datasheet. This rating ensures reliable blocking of high-voltage transients in offline AC-DC and industrial inverter applications. The FR107G must not be operated above this voltage in repetitive reverse-bias conditions to prevent avalanche breakdown or premature failure.
Is FR107G qualified to AEC-Q101 standards?
The base FR107G part is not AEC-Q101 qualified; however, the variant FR107GH (with 'H' suffix) is explicitly qualified per AEC-Q101. Engineers requiring automotive-grade reliability must specify FR107GH - the FR107G itself meets all electrical and mechanical specs but lacks the stress-test validation required for automotive powertrain or body electronics deployment.
What is the forward voltage drop (VF) of FR107G at rated current?
The FR107G exhibits a maximum forward voltage of 1.3 V at 1 A and 25 °C, as specified in the electrical characteristics table. At elevated temperatures (e.g., 125 °C), VF decreases slightly due to semiconductor physics, but design margins should be based on the 1.3 V max value to ensure worst-case conduction loss calculation and thermal management accuracy for the FR107G.
What package type does FR107G use, and is it lead-free?
The FR107G uses the DO-204AL (DO-41) axial-leaded package with pure tin-plated leads, fully compliant with J-STD-002 solderability standards. It is RoHS-compliant and halogen-free per IEC 61249-2-21 - confirming lead-free construction and environmental compliance for global manufacturing and end-of-life processing of the FR107G.
How does the reverse recovery time (trr) of FR107G compare to other FR-series devices?
The FR107G has a trr of 500 ns - the longest in the FR101G–FR107G family - because higher VRRM devices trade speed for voltage capability. FR101G–FR104G range from 150 ns to 250 ns; FR105G is 250 ns; FR106G and FR107G both specify 500 ns. This makes the FR107G appropriate for ≤200 kHz switching, unlike faster variants used in MHz-range GaN-based topologies.
