Product details
Overview
ES1GFSH from Taiwan Semiconductor is a 1 A, 400 V repetitive peak reverse voltage (VRRM) super fast surface-mount rectifier in SOD-128 package, featuring 35 ns reverse recovery time (trr), 0.93 V typical forward voltage at 1.0 A and 25°C, and AEC-Q101 qualification for automotive use.
For engineers reviewing the ES1GFSH datasheet, ES1GFSH pinout, ES1GFSH application, or ES1GFSH equivalent, key selection criteria include its 400 V VRRM, 35 ns trr, SOD-128 thermal performance (RθJL = 28°C/W), and suitability for high-frequency freewheeling and snubber circuits in automotive DC/DC converters.
Technical Context
This single-die, glass-passivated silicon rectifier delivers super-fast switching with low forward voltage and minimal reverse recovery charge, enabling high-efficiency operation in switching power supplies. Its junction-to-lead thermal resistance of 28°C/W supports reliable 1 A continuous conduction on standard PCB copper pads.
The device operates across –55°C to +150°C junction temperature range, maintains ≤1 µA reverse leakage at 25°C and rated VRRM, and exhibits 16 pF junction capacitance at 1 MHz and 4 V reverse bias - critical for minimizing switching noise in high-frequency topologies.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-ES1G-M3/5BT | VRRM = 400 V, trr = 35 ns, VF = 0.95 V @ 1 A, same SOD-128 package | No AEC-Q101 qualification; rated for commercial/industrial only | Select for cost-sensitive non-automotive designs where automotive qualification is not required |
| ON Semiconductor MUR140RLG | VRRM = 400 V, trr = 50 ns, VF = 1.05 V @ 1 A, DO-41 package (larger footprint, higher RθJA) | Slower recovery and through-hole mounting limit high-frequency and space-constrained use | Select only when legacy DO-41 layout compatibility is mandatory and 15 ns slower trr is acceptable |
Compared with VS-ES1G-M3/5BT and MUR140RLG, ES1GFSH uniquely combines AEC-Q101 qualification, 35 ns trr, and SOD-128 thermal performance - making it the preferred choice for automotive-grade, high-density, high-frequency rectification where reliability and layout efficiency are critical.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for ES1GFSH?
The ES1GFSH has a VRRM of 400 V, meaning it can reliably block up to 400 V in reverse bias without breakdown. This rating is confirmed in the Absolute Maximum Ratings table and applies across the full operating temperature range. The ES1GFSH is part of the ES1BFSH–ES1JFSH family, where 'G' explicitly denotes the 400 V version. Exceeding this voltage risks irreversible junction failure.
Is ES1GFSH qualified for automotive applications?
Yes, ES1GFSH is AEC-Q101 qualified, as explicitly stated in the FEATURES section of the official datasheet. This qualification covers stress testing for temperature cycling, humidity, mechanical shock, and other automotive-grade reliability requirements. The device is intended for under-hood and body electronics applications where robustness against thermal and environmental stress is essential.
What is the forward voltage (VF) of ES1GFSH at 1 A and 25°C?
The typical forward voltage of ES1GFSH is 0.93 V at 1.0 A and 25°C, with a maximum of 1.30 V under the same conditions. This value is measured per pulse test (PW = 0.3 ms) and reflects conduction loss during normal operation. At 125°C, VF drops to 0.77 V typical, improving efficiency in thermally demanding environments.
What package type does ES1GFSH use, and what are its key mechanical attributes?
ES1GFSH uses the SOD-128 surface-mount package: low-profile, UL 94V-0 compliant, with matte tin-plated leads solderable per J-STD-002. It weighs approximately 0.028 g, features polarity indicated by a cathode band, and meets JESD 201 Class 2 whisker resistance. The package supports automated placement and offers RθJL = 28°C/W when mounted on a 5 mm × 5 mm copper pad.
What is the reverse recovery time (trr) of ES1GFSH, and why does it matter?
The reverse recovery time of ES1GFSH is 35 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This ultra-fast recovery minimizes switching losses and voltage spikes in high-frequency power converters. In buck or flyback topologies operating above 100 kHz, a trr of 35 ns helps maintain efficiency and reduce EMI compared to standard or fast recovery diodes with trr > 50 ns.
