Product details
Overview
ES1DFSH from Taiwan Semiconductor is a 1A, 200V super fast surface-mount rectifier in SOD-128 package, featuring 35ns reverse recovery time, 0.85V forward voltage at 1.0A/25°C, and AEC-Q101 qualification for automotive use in DC/DC converters and snubber circuits.
For engineers reviewing the ES1DFSH datasheet, ES1DFSH pinout, ES1DFSH application, or ES1DFSH equivalent, key selection criteria include repetitive peak reverse voltage (200V), surge current capability (30A @ 8.3ms), junction temperature range (–55°C to +150°C), thermal resistance (RθJL = 28°C/W), and low-profile SOD-128 packaging for high-density automotive PCB layouts.
Technical Context
This discrete silicon rectifier employs a glass-passivated PN junction optimized for fast switching and low conduction loss. Its 35ns trr and 18pF junction capacitance at 1MHz/4V support high-frequency operation in flyback and buck-derived topologies.
The device operates across –55°C to +150°C junction temperature with RθJA = 67°C/W on a 5mm × 5mm Cu pad, enabling reliable thermal performance in constrained automotive under-hood environments without forced airflow.

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-1EFH02-M3/5AT | Same SOD-128 package, 200V VRRM, but 50ns trr and 0.92V VF @ 1A/25°C | Higher conduction and switching losses; less suitable for >150kHz designs | Prefer ES1DFSH where faster recovery and lower VF are critical for efficiency |
| ON Semiconductor MUR120RLG | SOD-123 package, 200V VRRM, 60ns trr, 0.95V VF @ 1A/25°C, no AEC-Q101 qualification | Smaller footprint but higher thermal resistance (RθJA ≈ 100°C/W) and non-automotive grade | Choose ES1DFSH for automotive compliance, thermal performance, and automated assembly compatibility |
Compared with VS-1EFH02-M3/5AT and MUR120RLG, ES1DFSH delivers superior high-frequency efficiency via 35ns trr and lower VF, while its AEC-Q101 status and SOD-128 thermal design make it the preferred choice for automotive and thermally constrained industrial power stages.

FAQ
What is the maximum repetitive peak reverse voltage rating for ES1DFSH?
The ES1DFSH has a maximum repetitive peak reverse voltage (VRRM) of 200 V, verified per Taiwan Semiconductor's B2103 datasheet. This rating defines the highest reverse-biased voltage the device can block continuously without breakdown. Engineers must ensure system-level reverse transients remain below this value, especially in automotive 24V systems with load dump events. The ES1DFSH maintains this rating across its full operating junction temperature range of –55°C to +150°C.
Is ES1DFSH qualified for automotive applications?
Yes, ES1DFSH is AEC-Q101 qualified, confirming its suitability for automotive electronic systems. This qualification includes stress testing for temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge per JEDEC standards. The device's glass-passivated junction, halogen-free construction, and moisture sensitivity level 1 further support robustness in automotive under-hood environments. ES1DFSH is explicitly listed in TSC's automotive-grade rectifier portfolio.
What is the forward voltage drop of ES1DFSH at 1.0A and 25°C?
The forward voltage drop (VF) of ES1DFSH is 0.85 V at 1.0A and 25°C, with a maximum of 0.95 V under the same conditions. This value is measured using pulse testing (PW = 0.3ms) to avoid self-heating effects. At elevated temperatures (125°C), VF decreases to 0.71 V typical, improving conduction efficiency in thermally demanding applications. These values are confirmed in the Electrical Specifications table of the official ES1BFSH–ES1JFSH datasheet.
What package type does ES1DFSH use, and what are its mechanical features?
ES1DFSH uses the SOD-128 surface-mount package: a low-profile, molded epoxy case with matte tin-plated leads solderable per J-STD-002. It features a cathode band for polarity identification, weighs approximately 0.028g, and meets UL 94V-0 flammability rating. The package supports automated placement and has moisture sensitivity level 1, eliminating pre-reflow baking requirements. Dimensions and recommended pad layout are specified in the Package Outline Dimensions section of the datasheet.
What is the reverse recovery time (trr) of ES1DFSH, and how is it measured?
The reverse recovery time (trr) of ES1DFSH is rated at 35 ns maximum, measured under conditions of IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This parameter reflects the time required for the device to transition from forward conduction to reverse blocking state, directly impacting switching losses in high-frequency converters. The 35 ns value positions ES1DFSH as a super fast rectifier-significantly faster than standard recovery diodes-and is validated across the full temperature range per the official datasheet.
