Product details
Overview
F1T6G from Taiwan Semiconductor is a 1A, 800V fast recovery rectifier diode in TS-1 package, featuring 500 ns reverse recovery time, 1.3 V max forward voltage at 1 A, and 30 A surge capability - used in high-efficiency DC-DC converters and switching inverters.
For engineers reviewing the F1T6G datasheet, F1T6G pinout, F1T6G application, or F1T6G equivalent, key selection criteria include VRRM = 800 V, trr = 500 ns, VF ≤ 1.3 V at IF = 1 A, TJ(max) = 150 °C, and TS-1 package compatibility with automated SMT assembly.
Technical Context
The F1T6G employs a glass-passivated single-die silicon junction optimized for fast switching in medium-voltage power conversion. Its 800 V repetitive peak reverse voltage and 500 ns reverse recovery time enable stable operation in 60–100 kHz SMPS topologies.
Thermal performance is defined by RθJA = 90 °C/W and a maximum junction temperature of 150 °C. The device supports 30 A non-repetitive surge current (8.3 ms half-sine), making it suitable for transient-heavy industrial power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - blocks up to 800 V reverse voltage without breakdown in continuous operation |
| IF | 1 A - rated average forward current under specified thermal conditions |
| trr | 500 ns - enables efficient switching in 60–100 kHz converters with low switching loss |
| VF (max) | 1.3 V @ IF = 1 A, TJ = 25°C - limits conduction loss to ≤1.3 W per diode at full load |
| IFSM | 30 A - withstands short-duration surges typical of input rectification or motor drive freewheeling |
| TJ(max) | 150 °C - allows operation in enclosed industrial enclosures with limited airflow |
| RθJA | 90 °C/W - requires minimal PCB copper area for thermal management in TS-1 footprint |
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 |
|---|---|---|---|
| STTH1R08 | VRRM = 800 V, trr = 75 ns, VF = 1.15 V @ 1 A - faster but lower surge rating (25 A) | Better for high-frequency (>200 kHz) designs; less robust under surge | Select when minimizing switching loss dominates over surge resilience |
| ES1J | VRRM = 600 V, trr = 35 ns, VF = 1.7 V @ 1 A - lower voltage rating, higher VF | Suitable only for ≤600 V systems; higher conduction loss | Choose only if system VRRM requirement is ≤600 V and space constraints favor SMA package |
Compared with STTH1R08 and ES1J, the F1T6G delivers optimal balance of 800 V blocking, 500 ns trr, and 30 A surge capability in TS-1 - ideal for cost-sensitive industrial 100 kHz SMPS where reliability under transient stress is critical.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for F1T6G?
The F1T6G has a VRRM rating of 800 V, meaning it can reliably block up to 800 V of reverse voltage in continuous operation without breakdown. This value is confirmed in the Absolute Maximum Ratings table on page 1 of the H2104 datasheet revision and is specific to the F1T6G variant - not extrapolated from adjacent part numbers.
What is the reverse recovery time (trr) of F1T6G, and under what test conditions is it measured?
The F1T6G has a reverse recovery time (trr) of 500 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the Electrical Specifications table on page 2 of the H2104 datasheet. This parameter is explicitly assigned to F1T6G and F1T7G in the comparative trr table.
Is F1T6G RoHS compliant and halogen-free?
Yes, the F1T6G is RoHS compliant and halogen-free per IEC 61249-2-21, as stated in the FEATURES section of the H2104 datasheet. The TS-1 package uses green molding compound and pure tin-plated leads meeting J-STD-002 solderability standards.
Does F1T6G have AEC-Q101 qualification?
The base F1T6G is not AEC-Q101 qualified, but the F1T6GH variant - with identical electrical specs and TS-1 package - is AEC-Q101 qualified. The "H" suffix denotes automotive qualification, per the Ordering Information table in the H2104 datasheet.
What is the thermal resistance (RθJA) of F1T6G, and how does it affect PCB layout?
The F1T6G has a junction-to-ambient thermal resistance (RθJA) of 90 °C/W, measured in free-air conditions. This value implies that for 1 A continuous conduction at 1.3 V VF, ~1.3 W of power dissipation will raise the junction temperature by ~117 °C above ambient - requiring at least 25 mm² of 1 oz copper pad for safe operation at full rating.
