Product details
Overview
ES2GA 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 max forward voltage at 2 A and 25 °C, and 50 A peak surge current - used in DC-DC converters and snubber circuits for high-efficiency power conversion.
For engineers reviewing the ES2GA datasheet, ES2GA pinout, ES2GA application, or ES2GA equivalent, key selection criteria include repetitive peak reverse voltage (400 V), forward voltage drop under load, thermal resistance (20 °C/W junction-to-lead), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance for industrial and lighting power designs.
Technical Context
The ES2GA is a single-die, unidirectional silicon rectifier optimized for high-frequency switching applications. Its super fast recovery time (trr ≤ 35 ns) minimizes switching losses in SMPS topologies, while its glass-passivated junction ensures stable performance across temperature and humidity stress.
Designed for automated SMT assembly, the device uses matte tin-plated leads compliant with J-STD-002 solderability and meets JESD201 Class 2 whisker resistance. Polarity is marked by a cathode band on the DO-214AC (SMA) case, and the molding compound satisfies UL 94V-0 flammability rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - maximum repetitive reverse voltage the device blocks without breakdown; defines usable input voltage range in flyback or boost converters |
| IF | 2 A continuous - average forward current rating at TA = 75 °C; sets baseline conduction capability for compact power stages |
| trr | ≤35 ns - reverse recovery time measured at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables >100 kHz switching with low diode switching loss |
| VF | ≤1.30 V at IF = 2 A, TJ = 25 °C - forward voltage drop directly impacts conduction loss and thermal rise in high-duty-cycle operation |
| RθJL | 20 °C/W - junction-to-lead thermal resistance; enables direct heat transfer to PCB copper for passive thermal management |
| IR | ≤10 µA at VR = 400 V, TJ = 25 °C - low leakage preserves efficiency in high-impedance bias or hold-up circuits |
Pinout & Package
Package: DO-214AC (SMA), surface-mount, single anode-cathode configuration. Cathode indicated by molded band. Matte tin-plated leads, UL 94V-0 molding compound, 0.060 g typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); must be routed with adequate copper area for 2 A RMS |
| Cathode (Lead 2) | Forward current exit / reverse blocking terminal | Connected to output rail or positive bus; cathode band orientation confirms polarity during automated placement and visual inspection |
Key Features
| Feature | Design Value |
|---|---|
| Super fast recovery time | trr ≤ 35 ns enables efficient operation in 100–500 kHz SMPS without excessive diode switching loss or EMI generation |
| Glass passivated junction | Provides stable electrical parameters and long-term reliability under thermal cycling and humidity exposure per J-STD-020 Level 1 |
| Low profile DO-214AC (SMA) package | Height ≤ 2.6 mm allows use in space-constrained power modules and LED drivers where Z-height is critical |
| RoHS & halogen-free compliance | Meets IEC 61249-2-21 and EU RoHS directives - required for export to EU, Japan, and many industrial OEM supply chains |

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 | Same DO-214AC package; VF = 1.35 V (max @ 2 A), trr = 30 ns, VRRM = 400 V | Slightly faster trr but higher VF; marginally higher conduction loss at full load | Prefer when minimizing switching loss dominates over conduction loss in high-frequency designs |
| MBR240 | DO-214AC package; Schottky structure; VF = 0.52 V (typ @ 2 A), VRRM = 40 V only | Lower VF improves light-load efficiency but insufficient VRRM for 400 V applications | Not suitable as direct replacement; consider only in low-voltage (<60 V) DC-DC outputs |
Compared with STTH2R04 and MBR240, the ES2GA delivers optimal balance of 400 V blocking, 35 ns recovery, and 1.30 V VF in a cost-effective, halogen-free SMA package - making it preferred for mid-voltage industrial and lighting power supplies where reliability and regulatory compliance are prioritized.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for ES2GA?
The ES2GA has a VRRM rating of 400 V, meaning it can reliably block up to 400 V of reverse voltage in repetitive operation without breakdown. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version M2102) and defines the upper limit for input voltage handling in applications like flyback converters or snubbers where the ES2GA is deployed.
What is the forward voltage drop of ES2GA at rated current?
The ES2GA exhibits a maximum forward voltage (VF) of 1.30 V at 2 A forward current and 25 °C junction temperature. This specification is measured under pulsed conditions (PW = 0.3 ms) and directly impacts conduction loss and thermal design - a critical parameter when sizing heatsinking or evaluating efficiency in high-duty-cycle ES2GA applications.
Is ES2GA compatible with lead-free reflow soldering processes?
Yes, the ES2GA is fully compatible with lead-free reflow soldering. Its matte tin-plated leads meet J-STD-002 solderability requirements, and the device is rated at Moisture Sensitivity Level 1 per J-STD-020 - meaning it can be subjected to standard Pb-free reflow profiles (peak ~260 °C) without baking or special handling, supporting high-yield automated assembly of the ES2GA.
Does ES2GA have a specified reverse recovery time (trr)?
Yes, the ES2GA 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 value is documented in the Electrical Specifications section of the Taiwan Semiconductor datasheet and confirms the ES2GA's suitability for high-frequency switching applications where fast turn-off minimizes switching loss and EMI.
What package type does ES2GA use, and what are its mechanical highlights?
The ES2GA uses the DO-214AC (SMA) surface-mount package. Key mechanical features include UL 94V-0 flammability-rated molding compound, polarity indicated by a cathode band, JESD201 Class 2 whisker-resistant leads, and a low profile (≤2.6 mm height) ideal for space-constrained layouts - all verified in the Mechanical Data and Package Outline sections of the ES2GA datasheet.
