Product details
Overview
ES2GAH from Taiwan Semiconductor is a 2 A, 400 V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35 ns reverse recovery time, 1.30 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 ES2GAH datasheet, ES2GAH pinout, ES2GAH application, or ES2GAH equivalent, key selection criteria include peak repetitive reverse voltage (400 V), forward surge current rating (50 A), junction-to-lead thermal resistance (20 °C/W), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance.
Technical Context
The ES2GAH employs a glass-passivated single-die silicon junction optimized for high-efficiency switching in automotive and industrial power supplies. Its 35 ns trr enables operation in high-frequency DC-DC topologies while maintaining low conduction loss via 1.30 V VF at rated current.
Thermally, the device supports continuous operation up to +150°C junction temperature with RθJL = 20 °C/W and RθJA = 75 °C/W. Polarity is indicated by cathode band; terminals are matte tin-plated and solderable per J-STD-002.
Key Specifications

| IF | 2 A - continuous average forward current under specified thermal conditions |
| IFSM | 50 A - non-repetitive peak surge current capability (8.3 ms half-sine) |
| trr | 35 ns - reverse recovery time enabling high-frequency switching efficiency |
| VF @ 2A, 25°C | 1.30 V - forward voltage drop determining conduction loss in power stage |
| RθJL | 20 °C/W - junction-to-lead thermal resistance critical for heatsinkless PCB layout |
| Junction Temp | –55°C to +150°C - operating range supporting under-hood automotive environments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R04 | 400 V VRRM, 2 A IF, 30 ns trr, TO-220AC package | Through-hole mounting; higher thermal mass but requires hole drilling | Preferred where board space permits and higher surge robustness is needed |
| MBR240 | 40 V VRRM, 2 A IF, Schottky architecture, 0.55 V VF | Lower voltage rating; unsuitable for 400 V systems; no reverse recovery | Select only for ≤40 V output stages requiring ultra-low VF and zero trr |
Compared with STTH2R04 and MBR240, the ES2GAH uniquely balances 400 V blocking, 35 ns speed, and DO-214AC SMT compatibility-making it optimal for space-constrained automotive DC-DC and LED driver designs where AEC-Q101 compliance is mandatory.

FAQ
What is the peak repetitive reverse voltage rating for ES2GAH?
The ES2GAH has a peak repetitive reverse voltage (VRRM) rating of 400 V. This value is confirmed in the Absolute Maximum Ratings table on page 1 of the official Taiwan Semiconductor datasheet revision A2102. It defines the maximum reverse voltage the ES2GAH can block repeatedly without avalanche breakdown under normal operating conditions.
Is ES2GAH qualified for automotive applications?
Yes, ES2GAH is AEC-Q101 qualified, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including temperature cycling, high-temperature reverse bias (HTRB), and electrostatic discharge (ESD), confirming suitability for automotive power electronics such as body control modules and lighting systems.
What is the forward voltage drop of ES2GAH at 2 A and 25°C?
The forward voltage (VF) of ES2GAH is 1.30 V at 2 A forward current and 25°C junction temperature, per the Electrical Specifications table in the datasheet. This value directly impacts conduction loss and thermal design in applications like DC-DC converters and LED drivers where the ES2GAH operates near its rated current.
Does ES2GAH have a defined reverse recovery time?
Yes, ES2GAH has a maximum reverse recovery time (trr) of 35 ns, measured at IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is specified in the Electrical Specifications table and confirms its classification as a super fast recovery rectifier, essential for minimizing switching losses in high-frequency power supplies using the ES2GAH.
What package type does ES2GAH use, and what are its key mechanical attributes?
ES2GAH uses the DO-214AC (SMA) package, as confirmed in the MECHANICAL DATA and ORDERING INFORMATION sections. Key attributes include matte tin-plated leads (solderable per J-STD-002), UL 94V-0 flammability-rated molding compound, cathode polarity indicated by band, and approximate weight of 0.060 g-enabling automated placement and compact PCB layouts.
