Product details
Overview
F1T2G from Taiwan Semiconductor is a 1A, 100V fast recovery rectifier diode in TS-1 package, featuring VF ≤ 1.3V at 1A/25°C, trr = 150ns, and IFSM = 30A, used in DC-DC converters and switching-mode inverters for efficient unidirectional power conversion.
For engineers reviewing the F1T2G datasheet, F1T2G pinout, F1T2G application, or F1T2G equivalent, key selection criteria include peak reverse voltage (100V), thermal resistance (90°C/W), junction temperature range (–55°C to +150°C), and AEC-Q101 qualification availability for automotive-grade reliability validation.
Technical Context
The F1T2G employs a glass-passivated silicon PN junction optimized for fast recovery (trr = 150ns) and low conduction loss (VF ≤ 1.3V @ 1A). Its single-die TS-1 package supports high surge current capability (IFSM = 30A) and operates across –55°C to +150°C junction temperature range.
Designed for high-efficiency switching applications, it delivers low reverse leakage (IR ≤ 5µA @ 25°C, ≤150µA @ 125°C) and low junction capacitance (CJ = 15pF @ 1MHz/4V), enabling stable performance in high-frequency DC-DC and SMPS topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - maximum repetitive reverse blocking voltage without breakdown |
| IF | 1 A - continuous average forward current rating at TA = 25°C |
| trr | 150 ns - reverse recovery time under IF = 0.5A, IR = 1.0A, Irr = 0.25A |
| VF | ≤1.3 V - forward voltage drop at IF = 1A and TJ = 25°C, defining conduction loss |
| RθJA | 90 °C/W - junction-to-ambient thermal resistance, critical for heatsink-less PCB layout |
| IFSM | 30 A - non-repetitive peak forward surge current (8.3ms half-sine), supporting inrush tolerance |
| TJ max | +150 °C - maximum allowable junction temperature, enabling operation in high-ambient environments |
Pinout & Package
TS-1 package: surface-mount, single-anode/single-cathode configuration with cathode band marking; lead-free, pure tin-plated terminals compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry | Connects to lower-potential side of rectification path; polarity must align with input source |
| Cathode | Forward current exit / reverse blocking terminal | Marked by visible band; connects to output/load side; withstands up to 100V reverse bias |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enhances moisture and contamination resistance, improving long-term reliability in humid or industrial environments |
| Low VF (≤1.3V @ 1A) | Reduces conduction losses by ~15% vs. standard recovery diodes, directly lowering thermal load in compact layouts |
| Fast trr (150ns) | Minimizes switching loss and EMI generation in 50–500kHz SMPS designs, supporting higher frequency operation |
| AEC-Q101 qualified option | Validated for automotive power modules requiring stress-tested robustness (e.g., body control units, LED drivers) |
| RoHS & halogen-free | Complies with IEC 61249-2-21 and EU RoHS directives, enabling use in eco-sensitive consumer and industrial products |
Applications
| DC-DC Converter | Switching Inverter |
|---|---|
Use Scenario: Step-down (buck) converter in portable battery-powered equipment with 12V input and 5V/1A output. IC Role / Device Role / Timing Role: Output rectifier handling continuous 1A DC current and high-frequency AC ripple.

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 | VRRM = 600V, trr = 75ns, VF = 1.15V @ 1A, TO-220AC package | Higher voltage rating and faster recovery, but larger footprint and higher thermal mass | Select when >100V blocking or <100ns trr required; not drop-in due to package and pinout mismatch |
| ON Semi MUR110 | VRRM = 100V, trr = 75ns, VF = 1.0V @ 1A, DO-41 package | Same VRRM, lower VF and faster trr, but through-hole mounting and lower IFSM (25A) | Prefer for prototyping or legacy through-hole boards; unsuitable for high-surge or SMT-only production |
Compared with STTH1R06 and MUR110, the F1T2G offers optimal balance of 100V rating, 150ns trr, SMT-ready TS-1 footprint, and 30A surge capability-making it ideal for space-constrained, high-reliability 1A switching supplies where AEC-Q101 compliance may be added via suffix H.

FAQ
What is the maximum junction temperature rating for the F1T2G?
The F1T2G has a maximum junction temperature (TJ max) of +150°C, verified per absolute maximum ratings table. This allows reliable operation in high-ambient environments such as engine compartments or enclosed power supplies. Derating curves confirm usable current down to 0.5A at +100°C ambient. The F1T2G must be mounted on copper area ≥25 mm² to maintain this rating under full load.
Does the F1T2G have AEC-Q101 qualification?
The base F1T2G is not AEC-Q101 qualified; however, the variant F1T2GH (with 'H' suffix) is fully AEC-Q101 certified per Version H2104 documentation. That version undergoes extended stress testing including temperature cycling, HTSL, and unbiased HAST. For automotive applications, specify F1T2GH-not F1T2G-to ensure compliance.
What is the reverse recovery time (trr) of the F1T2G and under what test conditions?
The F1T2G has a typical reverse recovery time (trr) of 150ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A per the Electrical Specifications table. This value is confirmed across all F1T1G–F1T4G variants. The F1T2G's trr remains stable up to TJ = 125°C, making it suitable for fixed-frequency 100–300kHz SMPS designs.
How does the F1T2G compare to Schottky diodes in 1A applications?
The F1T2G offers higher VRRM (100V vs. typical 45V for 1A Schottkys) and superior thermal stability (TJ max = +150°C vs. +125°C), but higher VF (~1.3V vs. ~0.5V). It avoids reverse leakage escalation at high temperature-critical in 125°C ambient designs. The F1T2G is preferred over Schottky when blocking voltage >60V or high-temperature reliability outweighs conduction loss.
What packaging options are available for the F1T2G?
The F1T2G is supplied in TS-1 package only, available in two standard formats: 5,000-piece tape-and-reel (ordering code F1T2G) and 3,000-piece ammo box (ordering code F1T2G A0G). Both use pure tin-plated leads compliant with J-STD-002 and meet UL 94V-0 flammability. No SOIC, SOD-123, or DO-214 variants exist for this part number.
