Product details
Overview
F1T1G from Taiwan Semiconductor is a 1A, 50V fast recovery rectifier diode in TS-1 package, featuring VF ≤ 1.3V at 1A/25°C, trr ≤ 150ns, and IR ≤ 5µA at 25°C. It serves as a primary output rectifier in low-voltage DC-DC converters where efficiency and compact size are critical.
For engineers reviewing the F1T1G datasheet, F1T1G pinout, F1T1G application, or F1T1G equivalent, key selection criteria include repetitive peak reverse voltage (50V), surge current capability (30A), thermal resistance (90°C/W), and AEC-Q101 qualification status for automotive-grade reliability validation.
Technical Context
The F1T1G employs a glass-passivated single-die silicon junction optimized for fast switching in low-voltage power conversion. Its 150ns reverse recovery time and 1.3V max forward voltage directly support high-frequency operation with reduced conduction and switching losses.
Designed for surface-mount assembly in TS-1 outline, the device uses pure tin-plated leads compliant with J-STD-002 and meets JESD201 Class 2 whisker resistance. Polarity is marked by a cathode band; maximum junction temperature is 150°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Avg) | 1 A - Continuous forward current rating defines maximum steady-state output rectification capacity |
| VRRM | 50 V - Peak reverse blocking voltage determines safe operating range in low-voltage secondary-side circuits |
| VF (max) | 1.3 V @ 1A, 25°C - Low conduction loss enables higher efficiency in 3.3V–12V DC-DC outputs |
| trr (max) | 150 ns - Fast recovery minimizes switching loss and EMI in 100–500 kHz SMPS designs |
| IFSM | 30 A - Surge rating supports transient overload tolerance during startup or fault conditions |
| RθJA | 90 °C/W - Thermal resistance indicates need for minimal copper area or airflow in thermally constrained layouts |
| IR (max) | 5 µA @ 25°C - Low leakage preserves efficiency in standby and light-load modes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar fast recovery rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR105 | Same IF (1A), VRRM (50V), but TO-220AC package; VF = 1.25V typ, trr = 75ns | Through-hole mounting; higher thermal mass but larger footprint and manual assembly requirement | Select when board-level reflow is unavailable or higher surge margin is needed via heatsinking |
| Vishay VS-1EWH05 | Same TS-1 package, IF = 1A, VRRM = 50V; VF = 1.15V typ, trr = 100ns, RθJA = 85°C/W | Lower VF and faster trr improve efficiency in high-frequency designs; same SMT compatibility | Prefer for new designs targeting <1.2V VF and <120ns trr while retaining identical footprint and assembly process |
Compared with MUR105 and VS-1EWH05, the F1T1G offers balanced performance in a cost-optimized TS-1 SMT package-slightly higher VF and trr than VS-1EWH05 but significantly smaller and more manufacturable than MUR105's through-hole form factor.

FAQ
What is the maximum junction temperature rating for the F1T1G?
The F1T1G has a maximum junction temperature (TJ MAX) of 150°C, verified per absolute maximum ratings in the official datasheet. This rating allows reliable operation in high-ambient environments such as enclosed automotive ECUs or industrial enclosures. Derating curves confirm usable current capacity down to 0.5A at 125°C ambient. The F1T1G must be mounted on adequate copper to maintain TJ ≤ 150°C under full 1A load.
Is the F1T1G RoHS and halogen-free compliant?
Yes, the F1T1G is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the "Features" and "Ordering Information" sections of the official datasheet. The TS-1 package uses UL 94V-0 molding compound and pure tin-plated leads meeting J-STD-002 solderability standards. These compliance attributes are inherent to all F1T1G units-not optional variants-and apply to both tape-and-reel and ammo box packaging formats.
Does the F1T1G have AEC-Q101 qualification?
The base F1T1G is not AEC-Q101 qualified; however, the variant F1T1GH is explicitly listed as AEC-Q101 qualified in the ordering table and features section. F1T1GH shares identical electrical parameters and TS-1 package but undergoes additional stress testing per AEC-Q101 Rev D. For automotive applications requiring qualification, F1T1GH-not F1T1G-must be specified and sourced.
What is the reverse recovery time (trr) specification for the F1T1G?
The F1T1G has a maximum reverse recovery time (trr) of 150 ns, measured at IF = 0.5A, IR = 1.0A, and Irr = 0.25A per the Electrical Specifications table. This value is confirmed for the F1T1G grade only; higher-voltage variants (e.g., F1T5G) specify up to 250 ns. The 150 ns trr enables stable operation in 200–500 kHz switching power supplies without significant ringing or cross-conduction loss.
What does the marking code 'F1T1G' indicate on the device body?
The marking code 'F1T1G' on the F1T1G device identifies it as the 50V version of the F1T-series fast recovery rectifier. Per the Absolute Maximum Ratings table, 'F1T1G' corresponds to VRRM = 50V; 'G' denotes green (halogen-free) compound; date and factory codes appear separately (e.g., 'YW' and 'F'). No additional functional or grading information is encoded in the base marking-electrical binning is performed post-test and not laser-marked.
