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. It serves as primary output rectifier in high-voltage DC-DC converters requiring low conduction loss and robust surge handling.
For engineers reviewing the F1T7G datasheet, F1T7G pinout, F1T7G application, or F1T7G equivalent, key selection criteria include peak reverse voltage rating (1000 V), thermal resistance (90 °C/W), junction temperature range (–55 to +150 °C), and AEC-Q101 qualification availability for automotive-grade reliability validation.
Technical Context
The F1T7G employs a single-die, glass-passivated PN junction optimized for fast switching in high-frequency power conversion. Its 500 ns trr and 15 pF junction capacitance enable efficient operation in 50–500 kHz SMPS topologies while maintaining low stored charge.
Designed for unidirectional current flow, it supports repetitive peak reverse voltages up to 1000 V and withstands non-repetitive surge currents of 30 A (8.3 ms half-sine). The TS-1 package provides UL 94V-0 mold compound and pure tin-plated leads compliant with J-STD-002 solderability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Maximum repetitive reverse blocking voltage; defines upper limit for DC bus or flyback secondary-side voltage stress |
| IF | 1 A continuous - Average forward current rating at TA = 25°C; derates linearly above 25°C per Fig.1 |
| trr | 500 ns - Reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; determines switching loss and EMI in hard-switched converters |
| VF (max) | 1.3 V @ 1 A, 25°C - Forward voltage drop; directly impacts conduction loss (Pcond ≈ IF × VF) and thermal design |
| RθJA | 90 °C/W - Junction-to-ambient thermal resistance; used to calculate junction temperature rise under given power dissipation |
| IR (max) | 150 µA @ 125°C - Reverse leakage current at max operating junction temperature; critical for standby power and high-impedance bias networks |
Pinout & Package
TS-1 package: molded epoxy case with axial leads, cathode indicated by band, UL 94V-0 rated, 0.200 g typical weight, pure tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (lead without band) | Current entry terminal | Connects to lower-potential node (e.g., transformer secondary center-tap or switch node return path) |
| Cathode (lead with band) | Current exit terminal | Connects to output capacitor positive rail; polarity marking prevents reverse-bias installation error |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enhances long-term reliability and moisture resistance vs. epoxy-passivated alternatives; enables stable performance in humid industrial environments |
| AEC-Q101 qualified version available | Validated for automotive under-hood applications including engine control modules and ADAS power supplies where temperature cycling and vibration endurance are required |
| Low VF and low trr combination | Reduces total power loss (conduction + switching) in high-frequency converters, enabling smaller heatsinks and higher power density designs |
| 30 A IFSM surge rating | Withstands inrush and transient overloads common during cold-start or short-circuit recovery in offline SMPS without degradation |
Applications
| DC-DC Converter Output Rectification | Switching Mode Inverter Auxiliary Supply |
|---|---|
Use Scenario: Secondary-side rectification in isolated 48 V–400 V input DC-DC converters for telecom and server PSUs. IC Role / Device Role / Timing Role: Unidirectional power transfer device converting transformer AC output to regulated DC; no timing function. Use Value: 1000 V VRRM ensures margin against reflected transients; 500 ns trr minimizes switching losses at 200–300 kHz operation. | Use Scenario: Bias supply rectification in three-phase motor inverters for HVAC and industrial drives. IC Role / Device Role / Timing Role: High-reliability rectifier feeding gate driver and controller ICs; operates continuously under variable load and temperature. Use Value: 150 µA IR at 125°C maintains low standby loss; TS-1 package withstands mechanical vibration in rotating equipment. |

Use Scenario: 12 V/24 V auxiliary power supply in BCMs where AEC-Q101 compliance is mandatory. IC Role / Device Role / Timing Role: Primary rectifier in flyback or buck-derived auxiliary converter; handles cold-crank (4.5 V) to load-dump (40 V) transients. Use Value: AEC-Q101 qualified variant ensures qualification for automotive temperature cycling (-40°C to +125°C ambient); 30 A IFSM absorbs load-dump energy. | Use Scenario: Isolated auxiliary supply in programmable logic controllers with reinforced insulation requirements. IC Role / Device Role / Timing Role: Input-side rectifier in isolated DC-DC modules providing galvanic separation between field I/O and CPU logic. Use Value: Glass passivation and UL 94V-0 molding compound meet IPC-6012 and IEC 61800-5-1 safety standards for industrial isolation barriers. |
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; 100 ns trr; TO-220AC package; higher VF (1.7 V typ) | Lower voltage rating limits use to ≤600 V systems; TO-220 requires PCB footprint change and heatsinking | Select when faster recovery (100 ns) outweighs voltage headroom and board space constraints |
| ON Semi MUR110E | 1 A / 1000 V; 75 ns trr; DO-41 package; VF = 1.25 V max; not AEC-Q101 qualified | DO-41 has lower thermal resistance (75 °C/W) but lacks automotive qualification and TS-1's mechanical robustness | Prefer for cost-sensitive industrial designs where AEC-Q101 is unnecessary and lead spacing allows DO-41 mounting |
Compared with STTH1R06 and MUR110E, the F1T7G uniquely balances 1000 V blocking, 500 ns trr, TS-1 mechanical ruggedness, and AEC-Q101 option-making it optimal for space-constrained, high-reliability 1000 V rectification where thermal and environmental robustness are prioritized over ultra-fast recovery.

FAQ
What is the maximum junction temperature rating for the F1T7G?
The F1T7G has a maximum junction temperature (TJ MAX) of +150°C, with an operating junction temperature range from –55°C to +150°C. This rating enables reliable operation in high-ambient environments such as enclosed power supplies or under-hood automotive locations. Thermal design must ensure actual TJ remains below 150°C using RθJA = 90°C/W and measured power dissipation. The F1T7G datasheet specifies derating curves confirming safe operation down to zero current at 150°C ambient.
Does the F1T7G have AEC-Q101 qualification?
The base F1T7G is not AEC-Q101 qualified, but the variant F1T7GH (ordering code with "H" suffix) is explicitly AEC-Q101 qualified per the manufacturer's ordering information table. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and high-temperature operating life. For automotive applications requiring AEC-Q101 compliance, F1T7GH-not F1T7G-must be specified and sourced.
What is the reverse recovery time (trr) specification for the F1T7G?
The F1T7G has a maximum reverse recovery time (trr) of 500 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the Electrical Specifications table on page 2 of the official datasheet. The 500 ns trr applies specifically to the F1T7G and F1T6G variants; lower-voltage versions (e.g., F1T1G–F1T5G) have progressively shorter trr values (150–250 ns).
What package type does the F1T7G use, and what are its key mechanical properties?
The F1T7G uses the TS-1 package: an axial-leaded, molded epoxy case with UL 94V-0 flammability rating, pure tin-plated leads compliant with J-STD-002, and cathode polarity marked by a band. Its mechanical data confirms a typical weight of 0.200 g and compliance with JESD201 Class 2 whisker testing. The TS-1 outline dimensions and marking diagram are provided in the datasheet's Package Outline Dimensions section.
How does the forward voltage (VF) of the F1T7G compare to similar 1000 V rectifiers?
The F1T7G has a maximum forward voltage (VF) of 1.3 V at 1 A and 25°C, which is competitive among 1 A / 1000 V fast recovery rectifiers. For comparison, ON Semiconductor's MUR110E specifies 1.25 V max under identical conditions, while STMicroelectronics' STTH1R06 (600 V) specifies 1.7 V typ. The F1T7G's VF contributes to lower conduction loss in high-duty-cycle applications, especially when combined with its 90°C/W thermal resistance for effective heat dissipation in compact layouts.
