Product details
Overview
ES2LGH from Taiwan Semiconductor is a 2 A, 400 V super fast recovery surface-mount rectifier in DO-214AA (SMB) package, featuring 35 ns reverse recovery time, 1.30 V max forward voltage at 2 A and 25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in DC-DC converters and car lighting systems.
For engineers reviewing the ES2LGH datasheet, ES2LGH pinout, ES2LGH application, or ES2LGH equivalent, key selection criteria include its 400 V VRRM, 50 A IFSM, 150°C maximum junction temperature, glass-passivated junction, and DO-214AA mechanical compatibility with automated SMT assembly.
Technical Context
This single-die, unidirectional silicon rectifier uses a planar passivated junction to achieve super-fast switching performance. Its 35 ns trr and low 20 pF junction capacitance support high-frequency operation in switching power supplies.
The device operates across –55°C to +150°C junction temperature range, with thermal resistance RθJL = 35°C/W and RθJA = 80°C/W on standard 16 mm × 16 mm PCB copper pad - enabling stable thermal management in compact automotive and industrial layouts.
Key Specifications

| VRRM | 400 V - peak reverse blocking capability for 280 VRMS AC line or 400 V DC bus applications |
| IF | 2 A continuous - rated average forward current under defined thermal conditions |
| IFSM | 50 A - surge withstand for 8.3 ms half-sine, supporting inrush and fault-current handling |
| trr | 35 ns - enables high-frequency switching (>1 MHz) with minimal switching loss |
| VF | ≤1.30 V @ 2 A, 25°C - low conduction loss critical for efficiency in 12 V/24 V automotive systems |
| CJ | 20 pF @ 1 MHz, 4 V - low capacitance reduces EMI and improves high-speed transient response |
| TJ max | +150°C - supports operation in under-hood environments without derating |

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-ES2DHE3/5BT | Same DO-214AA package; 200 V VRRM, 0.94 V VF max - lower voltage rating and forward drop | Suitable only for ≤200 V circuits; not rated for automotive AEC-Q101 | Select when cost-sensitive non-automotive 200 V applications require lowest VF |
| ON Semiconductor MUR240RLG | DO-214AC (SMA) package; 400 V VRRM, 1.3 V VF, 50 ns trr - slower recovery and smaller thermal pad area | Lower power dissipation capability due to higher RθJA (~100°C/W); not AEC-Q101 qualified | Use where board space is constrained but automotive qualification is not required |
Compared with VS-ES2DHE3/5BT and MUR240RLG, ES2LGH uniquely combines AEC-Q101 qualification, 400 V rating, 35 ns recovery, and DO-214AA thermal performance - making it the only drop-in solution for automotive 12 V/24 V DC-DC and lighting designs requiring full compliance and efficiency.

FAQ
What is the peak repetitive reverse voltage rating of ES2LGH?
The ES2LGH has a peak repetitive reverse voltage (VRRM) rating of 400 V, verified per Taiwan Semiconductor's A2102 datasheet. This allows safe operation in circuits with up to 400 V DC reverse bias or 280 VRMS AC input. The device maintains this rating across its full operating junction temperature range of –55°C to +150°C.
Is ES2LGH qualified for automotive applications?
Yes, ES2LGH is AEC-Q101 qualified per the official Taiwan Semiconductor documentation. It undergoes stress testing for temperature cycling, humidity, high-temperature reverse bias, and mechanical shock - confirming suitability for automotive power electronics including lighting, body control modules, and DC-DC converters.
What is the forward voltage drop of ES2LGH at rated current?
ES2LGH exhibits a maximum forward voltage (VF) of 1.30 V at 2 A forward current and 25°C junction temperature, as specified in the electrical characteristics table. At 125°C, VF decreases slightly due to semiconductor physics, remaining below 1.25 V under same conditions.
Does ES2LGH have a defined reverse recovery time?
Yes, ES2LGH has a typical reverse recovery time (trr) of 35 ns, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This value is confirmed in the "ELECTRICAL SPECIFICATIONS" section of the A2102 datasheet and enables efficient operation in switching frequencies up to 1 MHz.
What package type does ES2LGH use and what are its mounting features?
ES2LGH uses the DO-214AA (SMB) surface-mount package with matte tin-plated leads compliant with J-STD-002 solderability. Its polarity is marked by a cathode band, and it meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability standards - optimized for automated pick-and-place and lead-free reflow.
