Product details
Overview
F1T7G from Taiwan Semiconductor is a 1A, 1000V fast recovery rectifier diode in TS-1 package, featuring 500 ns reverse recovery time, 1.3 V max forward voltage at 1 A, and 150 µA max reverse leakage at 125°C - deployed in high-voltage DC-DC converters and industrial inverters.
For engineers reviewing the F1T7G datasheet, F1T7G pinout, F1T7G application, or F1T7G equivalent, key selection criteria include verified 1000 V repetitive peak reverse voltage, TS-1 package thermal resistance of 90°C/W, AEC-Q101 qualification availability (F1T7GH variant), and cathode-band polarity marking for board-level assembly verification.
Technical Context
The F1T7G implements a single-die, glass-passivated PN junction optimized for fast switching in high-voltage power conversion. Its 500 ns trr and 15 pF junction capacitance support operation up to several hundred kHz in flyback and forward topologies.
Rated for 150°C maximum junction temperature and 30 A non-repetitive surge current (8.3 ms half-sine), it sustains reliable conduction under transient overloads common in motor drives and UPS systems without thermal runaway.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - supports input stages handling 700 VDC bus rails with 30% safety margin |
| IF | 1 A continuous - suitable for low-to-medium power SMPS outputs up to ~15 W at 12 V |
| trr | 500 ns - enables efficient switching in 100–300 kHz converters with minimal switching loss |
| VF (max) | 1.3 V @ 1 A, 25°C - contributes ≤1.3 W conduction loss per device at full load |
| RθJA | 90 °C/W - requires ≥1.5 cm² copper pour for safe 1 A operation at 70°C ambient |
| IR (max) | 150 µA @ 125°C - ensures negligible leakage current in high-temperature industrial environments |
Pinout & Package

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 (STMicroelectronics) | Same 1 A / 600 V rating; 150 ns trr; TO-220AC package; higher RθJA (~50°C/W) | Requires heatsink above ~0.5 A; not AEC-Q101 qualified | Select when lower trr is critical and board space allows TO-220 mounting |
| ES1J (ON Semiconductor) | 1 A / 600 V; 35 ns trr; SMA package; VF = 1.7 V (max); RθJA = 70°C/W | Better speed but higher conduction loss; smaller footprint; no AEC-Q101 option | Choose for ultra-fast <100 kHz designs where VF penalty is acceptable and size is constrained |
Compared with STTH1R06 and ES1J, the F1T7G uniquely delivers 1000 V capability in TS-1 form factor with validated 500 ns trr and optional AEC-Q101 qualification - making it the only choice for compact, high-voltage, automotive-grade rectification without derating or heatsinking.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the F1T7G?
The F1T7G has a maximum repetitive peak reverse voltage (VRRM) of 1000 V, as confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version H2104). This rating enables use in high-voltage DC-DC and inverter applications where transient overvoltage margins exceed 700 VDC. The F1T7G is the highest-voltage variant in the F1T1G–F1T7G series.
Does the F1T7G have AEC-Q101 qualification?
The base F1T7G is not AEC-Q101 qualified; however, the F1T7GH variant - identical in electrical and thermal specifications - is explicitly qualified per AEC-Q101 Rev D for automotive under-hood applications. The "H" suffix denotes qualification, and both variants share the same TS-1 package, 1000 V VRRM, and 500 ns trr. Always specify F1T7GH for automotive designs.
What is the reverse recovery time (trr) of the F1T7G and how is it measured?
The F1T7G has a reverse recovery time (trr) of 500 ns, measured under conditions IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, per the Electrical Specifications table. This value applies specifically to the F1T6G and F1T7G variants and reflects performance in high-frequency switching circuits. The test circuit diagram is provided in Figure 6 of the Taiwan Semiconductor datasheet (H2104).
What package type does the F1T7G use and what are its mechanical highlights?
The F1T7G uses the TS-1 package: a compact, surface-mount molded epoxy case with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. It features UL 94V-0 flammability rating, cathode polarity marked by a band, and weighs approximately 0.200 g - optimized for automated placement and high-density PCB layouts.
How does the F1T7G compare to the F1T5G in terms of key electrical parameters?
The F1T7G differs from the F1T5G primarily in VRRM (1000 V vs. 600 V) and trr (500 ns vs. 250 ns); both share identical IF = 1 A, IFSM = 30 A, VF ≤ 1.3 V, and TS-1 packaging. The higher VRRM makes F1T7G suitable for 800–1000 V bus systems, while its longer trr reflects trade-offs inherent in optimizing silicon for extreme voltage blocking rather than ultra-fast switching.
