Taiwan Semiconductor Corporation F1T7GH

Overview

F1T7GH 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 AEC-Q101 qualification for automotive-grade reliability. It serves as the primary output rectifier in high-voltage DC/DC converters requiring low conduction loss and robust surge handling.

For engineers reviewing the F1T7GH datasheet, F1T7GH pinout, F1T7GH application, or F1T7GH equivalent, key selection criteria include peak reverse voltage rating (1000 V), surge current capability (30 A), thermal resistance (90 °C/W), AEC-Q101 compliance status, and TS-1 package compatibility with automated SMT assembly.

Technical Context

This device implements 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 100–500 kHz SMPS topologies while maintaining low reverse leakage (≤150 µA at 125°C).

The TS-1 package provides pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance. Thermal performance is defined by R_θJA = 90 °C/W, supporting continuous 1 A operation up to 125°C ambient when mounted on standard 1-inch² copper pad.

FAQ

What is the peak repetitive reverse voltage rating of the F1T7GH?

The F1T7GH has a peak repetitive reverse voltage (V_RRM) rating of 1000 V. This value is confirmed in the Absolute Maximum Ratings table for the F1T7G variant in the official Taiwan Semiconductor datasheet (Version H2104). The "7" in F1T7GH explicitly denotes the 1000 V grade, making F1T7GH suitable for high-voltage DC/DC and industrial power applications where transient overvoltage immunity is essential. Operating above this rating risks irreversible junction breakdown.

Is the F1T7GH qualified to AEC-Q101 standards?

Yes, the F1T7GH is AEC-Q101 qualified. The "H" suffix in the ordering code explicitly indicates AEC-Q101 qualification per the Ordering Information section of the Taiwan Semiconductor datasheet (Version H2104). This certification covers stress tests including HTGB, HTRB, TCT, and mechanical shock, validating F1T7GH for use in automotive powertrain and body electronics where reliability under thermal and vibration stress is mandatory.

What is the reverse recovery time (t_rr) of the F1T7GH and how is it measured?

The F1T7GH has a reverse recovery time (t_rr) of 500 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A per the Electrical Specifications table. This value applies specifically to the F1T6G and F1T7G variants and is confirmed in the datasheet's trr row. The test uses a standardized half-sine waveform with defined di/dt and voltage slew rate, ensuring consistent comparison across fast recovery rectifiers used in high-frequency SMPS designs.

What package type does the F1T7GH use and what are its key mechanical features?

The F1T7GH uses the TS-1 package - a compact, axial-leaded, molded epoxy case with UL 94V-0 flammability rating. Key mechanical features include pure tin-plated leads compliant with J-STD-002 solderability, JESD201 Class 2 whisker resistance, cathode polarity marked by a band, and approximate weight of 0.200 g. These attributes support reliable automated assembly and long-term reliability in thermally demanding environments.

What is the maximum forward voltage drop of the F1T7GH at rated current?

The maximum forward voltage (V_F) of the F1T7GH is 1.3 V at 1 A forward current and 25°C junction temperature, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects. At elevated temperatures (e.g., 125°C), V_F decreases slightly, but system-level thermal design must ensure junction temperature remains within −55°C to +150°C limits to maintain F1T7GH performance and lifetime.
