Product details
Overview
F1T5GH from Taiwan Semiconductor is a 1A, 600V fast recovery rectifier diode in TS-1 package, featuring 250 ns reverse recovery time, 1.3 V max forward voltage at 1 A, and 5 µA max reverse leakage at 25°C; used in automotive-grade DC-DC converters requiring AEC-Q101 qualification.
For engineers reviewing the F1T5GH datasheet, F1T5GH pinout, F1T5GH application, or F1T5GH equivalent, key selection criteria include repetitive peak reverse voltage (600 V), surge current capability (30 A), thermal resistance (90 °C/W), junction temperature range (–55 to +150 °C), and AEC-Q101 qualification status.
Technical Context
The F1T5GH employs a glass-passivated single-die PN junction optimized for fast switching in high-frequency power conversion. Its 250 ns trr and low VF support efficiency-critical topologies like synchronous buck and flyback converters.
Designed for automotive under-hood environments, it meets JESD201 Class 2 whisker resistance and UL 94V-0 molding compound requirements, with pure tin-plated leads compliant to J-STD-002 solderability standards.

FAQ
What is the maximum junction temperature rating for the F1T5GH?
The F1T5GH has a maximum junction temperature (TJ) rating of +150 °C, verified per AEC-Q101 stress testing. This allows reliable operation in under-hood automotive environments and high-ambient industrial settings. The device must be thermally designed using its 90 °C/W RθJA value to ensure F1T5GH junction temperature remains within this limit during continuous 1 A operation.
Is the F1T5GH pin-compatible with other devices in the F1T1G–F1T7G series?
Yes, all F1T1G–F1T7G variants-including F1T5GH-share identical TS-1 package dimensions, pinout, and thermal characteristics. Only VRRM (600 V), VR(RMS) (420 V), and trr (250 ns) differ across the series; mechanical mounting and PCB layout for F1T5GH apply directly to F1T1G through F1T7G.
Does the F1T5GH meet automotive qualification standards?
Yes, the "H" suffix in F1T5GH explicitly denotes AEC-Q101 qualification. This includes rigorous testing for temperature cycling, high-temperature operating life, unbiased high-humidity bias, and mechanical shock-all performed per the AEC-Q101-REV-E standard. The F1T5GH is approved for use in automotive powertrain and body electronics systems.
What is the reverse recovery time (trr) specification for the F1T5GH?
The F1T5GH has a maximum reverse recovery time (trr) of 250 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This value is confirmed in the official Taiwan Semiconductor datasheet Version H2104 and enables efficient operation in switching power supplies up to ~1 MHz without excessive switching loss or EMI generation. The F1T5GH trr is slower than F1T1G–F1T4G but faster than F1T6G/F1T7G.
How does the F1T5GH compare to standard recovery rectifiers in terms of forward voltage?
The F1T5GH specifies a maximum forward voltage (VF) of 1.3 V at 1 A and 25°C-significantly lower than standard recovery rectifiers (typically ≥1.7 V). This 0.4 V reduction lowers conduction loss by ~25% at 1 A, directly improving system efficiency and reducing thermal load on the F1T5GH and surrounding components in continuous-duty applications.
