Product details
Overview
ES3ABH from Taiwan Semiconductor is a 3A, 50V super fast surface-mount rectifier diode in DO-214AA (SMB) package, featuring 35ns reverse recovery time, 0.86V forward voltage at 3A/25°C, and AEC-Q101 qualification for automotive use. It serves as a freewheeling or snubber diode in DC-DC converters and car lighting systems.
For engineers reviewing the ES3ABH datasheet, ES3ABH pinout, ES3ABH application, or ES3ABH equivalent, key selection criteria include peak repetitive reverse voltage (50V), surge current capability (100A), thermal resistance (RθJL = 24°C/W), junction temperature range (–55°C to +150°C), and RoHS/halogen-free compliance.
Technical Context
The ES3ABH is a single-die, glass-passivated silicon PN junction rectifier optimized for high-frequency switching. Its super fast recovery (trr ≤ 35ns) minimizes switching losses in hard-switched topologies, while low forward voltage (VF = 0.86V @ 3A, 25°C) improves conduction efficiency.
Designed for surface-mount assembly on PCBs with 10mm × 10mm copper pads, it delivers RθJA = 84°C/W and RθJC = 26°C/W under standardized test conditions. Polarity is marked by a cathode band, and terminals are matte tin-plated per J-STD-002.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback or clamp circuits |
| IF | 3 A - Continuous average forward current; supports compact power stages up to ~30W at typical duty cycles |
| trr | ≤35 ns - Reverse recovery time; enables operation up to ~3 MHz in resonant or quasi-resonant converters |
| VF @ 3A, 25°C | 0.86 V - Forward voltage drop; determines conduction loss (2.58 W at full load) |
| RθJL | 24 °C/W - Junction-to-lead thermal resistance; enables direct thermal coupling to PCB copper for passive cooling |
| IFSM | 100 A - Non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients without failure |

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-3EYH05-M3/45 | Same DO-214AA package; VRRM = 50 V; trr = 35 ns; VF = 0.87 V @ 3A, but not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial DC-DC but not safety-critical vehicle subsystems | Select when AEC-Q101 is not required and cost optimization is prioritized |
| ON Semiconductor MUR350E | DO-214AC (SMA) package; VRRM = 50 V; trr = 35 ns; VF = 0.92 V @ 3A; AEC-Q101 qualified | Smaller footprint (SMA) limits thermal dissipation; RθJA = 100°C/W vs. ES3ABH's 84°C/W | Select only if board space is constrained and thermal margin ≥15°C can be maintained |
Compared with VS-3EYH05-M3/45 and MUR350E, the ES3ABH uniquely combines AEC-Q101 qualification, DO-214AA thermal performance (RθJA = 84°C/W), and 0.86V forward drop - making it optimal for thermally demanding automotive power stages where reliability and efficiency are jointly critical.

FAQ
What is the maximum junction temperature rating for ES3ABH?
The ES3ABH has a maximum junction temperature (TJ) of +150°C and a minimum of –55°C. This wide operating range supports deployment in under-hood automotive environments and industrial enclosures with elevated ambient temperatures. The device's thermal performance - including RθJL = 24°C/W - ensures reliable operation within this envelope when mounted on a 10mm × 10mm Cu pad. Always verify actual board-level thermal design using the ES3ABH's derating curve.
Is ES3ABH suitable for automotive applications?
Yes, the ES3ABH is AEC-Q101 qualified and explicitly listed for automotive applications in its official documentation. It meets stress test requirements for temperature cycling, high-temperature reverse bias, and mechanical shock - making it appropriate for use in car lighting, body control modules, and DC-DC converters in passenger vehicles. Its halogen-free and RoHS-compliant construction further aligns with automotive environmental standards.
What is the forward voltage drop of ES3ABH at rated current?
The ES3ABH exhibits a typical forward voltage (VF) of 0.86 V at 3.0 A and 25°C, and 0.73 V at 3.0 A and 125°C. These values are measured under pulsed conditions (PW = 0.3 ms) and reflect low conduction losses critical for high-efficiency power designs. At light loads (1.5 A), VF is 0.80 V (25°C) and 0.66 V (125°C), enabling predictable loss modeling across operating conditions.
Does ES3ABH have a defined reverse recovery time?
Yes, the ES3ABH has a maximum reverse recovery time (trr) of 35 ns, tested at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This super fast recovery characteristic minimizes switching losses and voltage ringing in high-frequency power converters. The trr value is consistent across the ES3ABH–ES3JBH family and is verified per JEDEC test methods.
What package type does ES3ABH use, and is it compatible with standard SMT processes?
The ES3ABH uses the DO-214AA (SMB) surface-mount package, with matte tin-plated leads compliant with J-STD-002 solderability requirements. Its moisture sensitivity level is rated at Level 1 per J-STD-020 - meaning it can be stored indefinitely at ≤30°C/60% RH and placed directly into reflow without baking. The low-profile design (≤2.29 mm height) supports automated pick-and-place and standard IR/reflow profiles.
