Product details
Overview
ES2LDH from Taiwan Semiconductor is a 2 A, 200 V super fast recovery surface-mount rectifier diode in DO-214AA (SMB) package, featuring 35 ns reverse recovery time, 0.94 V forward voltage at 2 A and 25 °C, and AEC-Q101 qualification for automotive use in DC-DC converters and freewheeling circuits.
For engineers reviewing the ES2LDH datasheet, ES2LDH pinout, ES2LDH application, or ES2LDH equivalent, key selection criteria include repetitive peak reverse voltage (200 V), surge current rating (50 A), junction temperature range (–55 to +150 °C), thermal resistance (RθJL = 35 °C/W), and AEC-Q101 qualification status.
Technical Context
The ES2LDH is a single-die, glass-passivated silicon rectifier optimized for high-frequency switching applications. Its 35 ns trr and low VF enable high-efficiency operation in DC-DC converters and snubber networks where fast recovery and minimal conduction loss are critical.
Designed for automotive-grade reliability, it meets AEC-Q101 stress test requirements and features moisture sensitivity level 1 (per J-STD-020), halogen-free construction (IEC 61249-2-21), and matte tin-plated leads compliant with J-STD-002 solderability standards.

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-2EY20 | VRRM = 200 V, trr = 35 ns, VF = 0.95 V @ 2 A - nearly identical electrical specs | Not AEC-Q101 qualified; intended for industrial/commercial use only | Select when automotive qualification is not required and cost optimization is prioritized |
| ON Semiconductor MUR220 | VRRM = 200 V, trr = 35 ns, VF = 0.97 V @ 2 A - slightly higher forward drop | AEC-Q101 qualified; same automotive suitability but different thermal resistance (RθJA = 75 °C/W vs. 80 °C/W) | Select when tighter thermal margin on ambient-limited PCB layouts is needed |
Compared with VS-2EY20 and MUR220, the ES2LDH provides identical 200 V/2 A/35 ns performance with AEC-Q101 validation and superior moisture robustness (MSL 1), making it optimal for automotive production where reliability and process compatibility are mandatory.

FAQ
What is the maximum repetitive peak reverse voltage rating for ES2LDH?
The ES2LDH has a maximum repetitive peak reverse voltage (VRRM) of 200 V, verified per absolute maximum ratings in the official Taiwan Semiconductor datasheet (Version A2102). This rating defines the highest reverse-biased voltage the device can block continuously without breakdown under normal operating conditions.
Is ES2LDH qualified for automotive applications?
Yes, ES2LDH is AEC-Q101 qualified, confirmed in the manufacturer's official documentation. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing-making ES2LDH suitable for under-hood automotive systems such as lighting and power conversion modules.
What is the forward voltage drop of ES2LDH at rated current?
The ES2LDH exhibits a maximum forward voltage (VF) of 0.94 V at 2 A forward current and 25 °C junction temperature, as specified in the electrical characteristics table. This value is measured under pulse conditions (PW = 0.3 ms) and directly impacts conduction loss in high-current power paths.
What package type does ES2LDH use, and what are its mounting features?
ES2LDH uses the DO-214AA (SMB) surface-mount package with gull-wing leads. It features matte tin-plated terminals compliant with J-STD-002 solderability, polarity indicated by a cathode band, and MSL Level 1 moisture sensitivity-enabling standard reflow without pre-baking.
How does the thermal performance of ES2LDH support PCB-level heat dissipation?
ES2LDH has a junction-to-lead thermal resistance (RθJL) of 35 °C/W and junction-to-ambient (RθJA) of 80 °C/W when mounted on a 16 mm × 16 mm Cu pad test board. This allows effective heat transfer through the leads into the PCB copper, supporting reliable operation up to 150 °C junction temperature without external heatsinking.
