Product details
Overview
FR107G R1G 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 forward voltage at 1 A, and 30 A surge current capability; used in high-voltage DC-DC converters and switching inverters requiring reliable unidirectional conduction.
For engineers reviewing the FR107G R1G datasheet, FR107G R1G pinout, FR107G R1G application, or FR107G R1G equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (70 °C/W), junction temperature range (–55 to +150 °C), cathode-band polarity marking, and RoHS/halogen-free compliance for automotive and industrial power supplies.
Technical Context
This discrete silicon rectifier uses a glass-passivated PN junction optimized for fast recovery (trr = 500 ns) and low conduction loss (VF ≤ 1.3 V @ 1 A). It supports repetitive 1000 V reverse blocking with 30 A non-repetitive surge tolerance and operates across –55 °C to +150 °C junction temperature.
The device implements a single-die configuration in DO-204AL (DO-41) axial package with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance; polarity is marked by a visible cathode band.

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 | Same 1 A / 600 V rating but shorter trr (≈120 ns); TO-220AC package, not DO-41 | Higher-frequency (>300 kHz) designs where faster recovery outweighs axial mounting constraints | Select STTH1R06 only if board layout accommodates TO-220 footprint and thermal mass permits higher power density |
| 1N4937 | 1 A / 600 V, trr ≈ 200 ns, same DO-41 package but no AEC-Q101 option or halogen-free certification | Cost-sensitive consumer power adapters where automotive qualification and green compliance are not required | Choose 1N4937 for non-automotive, non-RoHS-critical applications where 600 V rating suffices and lower cost is prioritized |
Compared with STTH1R06 and 1N4937, FR107G R1G uniquely delivers 1000 V blocking with DO-41 compatibility and AEC-Q101-ready variants-making it optimal for high-voltage industrial and automotive auxiliary power stages where both voltage headroom and regulatory compliance are mandatory.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for FR107G R1G?
The FR107G R1G has a VRRM rating of 1000 V, meaning it reliably blocks up to 1000 volts of reverse-biased voltage in repetitive operation. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version H2104), and defines the upper limit for safe reverse-bias operation in high-voltage DC-DC and inverter applications where transient spikes must be contained without breakdown.
Does FR107G R1G have AEC-Q101 qualification?
The base FR107G R1G is not AEC-Q101 qualified; however, the variant FR107GH (same electrical specs, identical DO-41 package) is explicitly AEC-Q101 qualified per the ordering information section of the datasheet. FR107G R1G itself meets RoHS and halogen-free standards but requires verification of the "H" suffix in the full part number to confirm automotive qualification status.
What is the forward voltage drop (VF) of FR107G R1G at rated current?
The FR107G R1G exhibits a maximum forward voltage drop of 1.3 V at 1 A forward current and 25°C junction temperature, as specified in the Electrical Specifications table. This VF value directly determines conduction loss (P = IF × VF) and influences thermal design-e.g., at 1 A, conduction loss is ≤1.3 W, requiring appropriate PCB copper area or ambient derating per the forward current derating curve.
What package type does FR107G R1G use, and how is polarity identified?
FR107G R1G uses the DO-204AL (DO-41) axial-leaded package with glass-passivated chip junction. Polarity is unambiguously indicated by a cathode band printed on the body near one lead end; that banded lead is the cathode terminal, and the opposite lead is the anode. This marking aligns with JEDEC standard DO-41 mechanical drawings and is verified in the Marking Diagram section of the Taiwan Semiconductor datasheet.
What is the reverse recovery time (trr) of FR107G R1G, and under what test conditions is it measured?
The reverse recovery time (trr) of FR107G R1G is 500 ns, measured under the condition of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as stated in the Electrical Specifications table. This test setup reflects real-world commutation behavior in switching circuits and confirms suitability for operation up to ~200 kHz before recovery-related losses dominate efficiency.
