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 rated VRRM = 800 V, IF = 1 A continuous, trr = 500 ns, thermal resistance RθJA = 90 °C/W, and TS-1 leaded package compatibility with J-STD-002 soldering standards.
Technical Context
The F1T6G is a single-die, glass-passivated silicon PN junction rectifier optimized for fast switching in medium-voltage power conversion. Its 800 V repetitive peak reverse voltage and 500 ns reverse recovery time support operation in 48–400 V bus systems with minimal switching loss.
Designed for surface-mount-compatible through-hole assembly, it delivers low forward voltage (≤1.3 V @ 1 A, 25°C) and low leakage (≤5 µA @ 25°C, rated VR), enabling high efficiency in compact, thermally constrained designs such as industrial SMPS and automotive auxiliary power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - supports DC bus voltages up to 565 V RMS in bridge configurations without breakdown |
| IF | 1 A continuous - suitable for output rectification in ≤15 W isolated flyback or ≤25 W non-isolated buck-derived topologies |
| trr | 500 ns - enables stable operation at switching frequencies up to 200 kHz with controlled turn-off ringing |
| VF max | 1.3 V @ 1 A, 25°C - contributes ≤1.3 W conduction loss per device at full load, reducing heatsink requirements |
| IFSM | 30 A (8.3 ms half-sine) - withstands cold-start inrush and transient overloads in unregulated input stages |
| RθJA | 90 °C/W - requires ≥1.5 cm² copper pour for safe operation at 1 A ambient temperature ≤70°C |
Pinout & Package
TS-1 package: molded epoxy case with axial leads, cathode indicated by band, pure tin-plated terminals compliant with J-STD-002, UL 94V-0 rated compound, 0.200 g typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry node during forward conduction | Connected to lower-potential side of transformer secondary or switch node in synchronous rectifier auxiliary path |
| Cathode | Current exit node during forward conduction; marked with band | Connected to output rail or filter capacitor positive terminal; polarity must be verified before PCB placement |
Key Features
| Feature | Design Value |
|---|---|
| Glass passivated junction | Enables stable long-term reliability under humidity and thermal cycling; eliminates need for conformal coating in industrial environments |
| AEC-Q101 qualified version available (F1T6GH) | Validated for automotive under-hood applications including body control modules and HVAC power stages |
| Low IR (≤5 µA @ 25°C) | Minimizes standby power loss in always-on circuits such as smart meter real-time clocks or IoT wake-up supervisors |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU Directive 2011/65/EU for environmentally regulated end equipment |
Applications
| DC-DC Converter Output Rectification | Switching Inverter Freewheeling Path |
|---|---|
Use Scenario: Secondary-side rectification in 12 V output, 20 W flyback converter powering industrial sensors. IC Role / Device Role / Timing Role: Unidirectional current valve converting high-frequency AC from transformer into regulated DC; no timing function. Use Value: 1.3 V VF limits conduction loss to 1.3 W, enabling natural convection cooling without heatsink. | Use Scenario: Freewheeling diode across IGBT in 48 V battery-fed motor inverter for automated guided vehicle. IC Role / Device Role / Timing Role: Provides low-impedance return path during IGBT off-state; reverse recovery must be faster than switching period. Use Value: 500 ns trr ensures clean commutation at 15 kHz PWM, suppressing voltage overshoot beyond 800 V rating. |
| Automotive Auxiliary Power Supply | Industrial SMPS Input Bridge Leg |
Use Scenario: Input rectification stage in 12 V → 3.3 V buck converter for automotive infotainment system MCU supply. IC Role / Device Role / Timing Role: Part of discrete full-wave bridge; handles 1 A average input current from alternator ripple. Use Value: AEC-Q101-qualified variant (F1T6GH) sustains operation from −40°C to +125°C junction, meeting ISO 16750-4 pulse test requirements. | Use Scenario: One leg of single-phase input rectifier feeding PFC controller in 100 W industrial AC-DC power supply. IC Role / Device Role / Timing Role: Conducts during negative half-cycle; must block 600 V peak line transients. Use Value: 800 V VRRM provides 200 V margin above 600 V peak line, eliminating need for snubbers in 230 VAC nominal designs. |
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 = 150 ns, IF = 1 A, DO-41 package | Shorter trr but higher VF (1.7 V typ), less surge robustness (IFSM = 20 A) | Preferred where ultra-fast recovery dominates over conduction loss or surge margin |
| ON Semi MUR108 | VRRM = 800 V, trr = 75 ns, IF = 1 A, DO-41, AEC-Q101 not offered | Superior speed but no automotive qualification; higher cost per unit in tape-and-reel | Selected when board space is constrained and AEC-Q101 is not required |
Compared with STTH1R08 and MUR108, the F1T6G trades some speed for lower forward drop and higher surge tolerance in a TS-1 package optimized for manual and wave-solder assembly - making it preferred for cost-sensitive industrial and automotive aftermarket power supplies.

FAQ
What is the maximum junction temperature rating for F1T6G?
The F1T6G has a maximum junction temperature (TJ) rating of +150°C, with operational range from −55°C to +150°C. This allows reliable use in enclosed industrial enclosures or under-hood automotive locations where ambient temperatures exceed 85°C. Derating curves in the F1T6G datasheet specify that continuous current must be reduced to ~0.7 A at 100°C ambient to maintain TJ ≤ 150°C with standard PCB layout.
Does F1T6G have AEC-Q101 qualification?
The base F1T6G is not AEC-Q101 qualified; however, the variant F1T6GH is fully AEC-Q101 qualified and shares identical electrical and thermal specifications. F1T6GH undergoes additional stress testing including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing per AEC-Q101 Rev D. For automotive applications, F1T6GH must be specified explicitly in the BOM.
What is the reverse recovery time (trr) of F1T6G and how is it measured?
The F1T6G has a reverse recovery time (trr) of 500 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A, and TJ = 25°C. This value is confirmed in the official F1T6G datasheet Figure 6 test circuit and applies specifically to the F1T6G and F1T7G variants - other members of the F1T1G–F1T7G family have lower trr values.
What does the "G" suffix in F1T6G indicate?
The "G" suffix in F1T6G indicates green (halogen-free) molding compound compliant with IEC 61249-2-21 and RoHS Directive 2011/65/EU. It does not denote packaging type or qualification level. The full ordering code F1T6G specifies 800 V rating, TS-1 package, green compound, and standard reliability grade - distinct from F1T6GH (AEC-Q101) or F1T6G A0G (ammo box packaging).
Can F1T6G replace F1T5G in an existing design?
F1T6G can replace F1T5G only if the circuit's peak reverse voltage exceeds 600 V and remains ≤800 V. While both share identical IF, IFSM, package, and thermal specs, F1T6G has higher VRRM (800 V vs. 600 V) and longer trr (500 ns vs. 250 ns). Substitution may increase switching loss in high-frequency designs; verify voltage margin and EMI behavior before deployment. F1T6G is not a drop-in replacement without analysis.
