Product details
Overview
ES2GH from Taiwan Semiconductor is a 2A, 400V super fast recovery surface-mount rectifier diode in DO-214AA (SMB) package, featuring 35ns reverse recovery time, 1.30V max forward voltage at 2A/25°C, and AEC-Q101 qualification for automotive use in snubber and freewheeling circuits.
For engineers reviewing the ES2GH datasheet, ES2GH pinout, ES2GH application, or ES2GH equivalent, key selection criteria include repetitive peak reverse voltage (400V), surge current rating (50A), junction-to-lead thermal resistance (20°C/W), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
This single-die silicon rectifier uses glass passivated junction technology to achieve stable high-voltage blocking and low conduction loss. Its super fast recovery (trr ≤ 35ns) minimizes switching losses in high-frequency DC-DC converters and automotive lighting drivers.
The DO-214AA (SMB) package supports automated placement and provides 75°C/W junction-to-ambient thermal resistance. Polarity is marked by cathode band; terminals are matte tin-plated and solderable per J-STD-002.

|---|---|---|---|
| Vishay VS-ES2GHM3/5BT | Same DO-214AA package, 400V VRRM, 1.35V VF max @ 2A, AEC-Q101 qualified | Identical automotive qualification; slightly higher VF increases conduction loss by ~3% | Preferred where Vishay supply chain alignment is required; identical PCB fit |

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for ES2GH?
The ES2GH has a VRRM rating of 400 V, meaning it can reliably block reverse voltages up to this level in repetitive operation. This value is confirmed in the Absolute Maximum Ratings table on page 2 of the official TSC datasheet (Version A2102). Exceeding 400 V may cause avalanche breakdown or permanent damage to the ES2GH junction.
Is ES2GH qualified for automotive applications?
Yes, ES2GH is AEC-Q101 qualified, as explicitly stated in the FEATURES section of the TSC datasheet. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), making ES2GH suitable for under-hood and cabin automotive systems such as LED lighting and HVAC controls.
What is the forward voltage drop (VF) of ES2GH at rated current?
The ES2GH exhibits a maximum forward voltage of 1.30 V at 2 A and 25°C, per the Electrical Specifications table. This VF value directly impacts conduction loss and thermal dissipation-e.g., at 2 A, worst-case power loss is 2.6 W. The actual VF decreases at lower temperatures and increases slightly at elevated junction temperatures.
Does ES2GH have a defined reverse recovery time (trr)?
Yes, ES2GH has a specified reverse recovery time of ≤35 ns under test conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This trr value is critical for minimizing switching losses in high-frequency power supplies and is measured using the standard test circuit shown in Figure 6 of the TSC datasheet.
What package type does ES2GH use, and is it compatible with automated assembly?
ES2GH uses the DO-214AA (SMB) surface-mount package, which is explicitly noted as "ideal for automated placement" in the FEATURES section. Its low-profile design, J-STD-020 Level 1 moisture sensitivity, and matte tin-plated leads ensure compatibility with standard SMT reflow processes without pre-baking or special handling.
