Product details
Overview
ES2GALH from Taiwan Semiconductor is a 2A, 400V super fast surface-mount rectifier diode in Thin SMA package, featuring 35ns reverse recovery time, 0.97V forward voltage at 2A/25°C, and AEC-Q101 qualification for automotive use.
For engineers reviewing the ES2GALH datasheet, ES2GALH pinout, ES2GALH application, or ES2GALH equivalent, key selection considerations include its 400V VRRM, low-profile Thin SMA footprint, glass-passivated junction, and suitability for high-frequency freewheeling and snubber circuits in automotive DC/DC converters.
Technical Context
The ES2GALH employs a single-die silicon PN junction with glass passivation for enhanced reliability and moisture resistance (J-STD-020 Level 1). Its super fast recovery (trr ≤ 35ns) enables efficient operation in switching frequencies up to several hundred kHz.
Thermal performance is defined by RθJL = 24°C/W and RθJA = 72°C/W on a 5mm × 5mm Cu pad PCB. Junction temperature range is –55°C to +150°C, supporting under-hood automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - Maximum repetitive reverse voltage before breakdown; defines safe operating limit in 400V-rated power rails |
| IF | 2 A - Continuous forward current rating; supports sustained conduction in compact DC/DC output stages |
| trr | ≤35 ns - Reverse recovery time; enables low-loss operation in high-frequency (>100 kHz) switching topologies |
| VF @ 2A, 25°C | 0.97 V - Forward voltage drop; determines conduction loss (≈1.94 W at 2A) and thermal load in freewheeling paths |
| CJ @ 1MHz, 4V | 27 pF - Junction capacitance; impacts high-frequency noise coupling and switching speed in snubber networks |
| IFSM (8.3ms) | 50 A - Non-repetitive surge current capability; withstands inrush and fault transients in automotive power systems |
| TJ max | +150 °C - Maximum junction temperature; allows operation in engine compartment environments with minimal derating |
Pinout & Package
Package: Thin SMA - Low-profile surface-mount package (2.7mm × 4.2mm × 2.1mm), matte tin-plated leads, cathode indicated by band, RoHS and halogen-free compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of switched node (e.g., MOSFET source or inductor return); requires adequate copper pour for thermal dissipation |
| Cathode (banded end) | Forward current exit / reverse blocking terminal | Connected to higher-potential rail (e.g., output capacitor positive); polarity must be verified during placement to prevent catastrophic failure |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock per JESD22 standards |
| Glass passivated junction | Provides hermetic protection against moisture ingress and contamination, improving long-term stability in harsh environments |
| Low profile Thin SMA package | Enables high-density PCB layouts and compatibility with automated SMT assembly without tombstoning risk |
| 35 ns reverse recovery | Reduces switching losses and EMI generation compared to standard rectifiers, critical for >200 kHz DC/DC designs |
| J-STD-020 Level 1 moisture sensitivity | Eliminates need for baking prior to reflow, simplifying manufacturing and reducing process cost |

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 | 400V VRRM, 2A IF, trr = 30ns, TO-220AC package (larger, through-hole) | Requires PCB through-hole mounting and larger board area; higher thermal mass but better heatsinking potential | Select when higher surge robustness or legacy through-hole compatibility is required over SMT density |
| ON Semi MUR240 | 400V VRRM, 2A IF, trr = 35ns, SMA package, but not AEC-Q101 qualified | Lacks automotive qualification; suitable for industrial/commercial but not safety-critical automotive subsystems | Select for cost-sensitive non-automotive applications where AEC-Q101 is not mandated |
Compared with STTH2R04 and MUR240, the ES2GALH uniquely combines AEC-Q101 qualification, Thin SMA footprint, and 35ns recovery in a single automotive-grade SMT rectifier-enabling space-constrained, high-reliability designs without layout or qualification trade-offs.

FAQ
What is the peak repetitive reverse voltage rating of the ES2GALH?
The ES2GALH has a peak repetitive reverse voltage (VRRM) rating of 400 V. This value is explicitly specified in the Absolute Maximum Ratings table for the ES2GALH variant and defines the maximum reverse-biased voltage the device can block repeatedly without breakdown. It is distinct from the 100V (ES2BALH), 200V (ES2DALH), and 600V (ES2JALH) variants in the same family.
Is the ES2GALH qualified for automotive applications?
Yes, the ES2GALH is AEC-Q101 qualified, as confirmed in the FEATURES section of the official Taiwan Semiconductor datasheet. This qualification covers stress tests including temperature cycling, high-temperature operating life, and unbiased highly accelerated stress testing, making ES2GALH suitable for under-hood and other automotive power systems.
What is the forward voltage drop of the ES2GALH at 2A and 25°C?
The forward voltage (VF) of the ES2GALH is 0.97 V at 2A and 25°C, as listed in the Electrical Specifications table under "ES2GALH" column. The datasheet also specifies a maximum of 1.30 V under the same conditions, providing design margin for worst-case conduction loss calculation.
Does the ES2GALH have a defined reverse recovery time?
Yes, the ES2GALH has a maximum reverse recovery time (trr) of 35 ns, measured under conditions of IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A. This parameter is explicitly stated in the Electrical Specifications table and confirms its classification as a super fast rectifier suitable for high-frequency switching.
What package type does the ES2GALH use, and what are its key mechanical attributes?
The ES2GALH uses the Thin SMA package, as confirmed in the MECHANICAL DATA and ORDERING INFORMATION sections. Key attributes include dimensions of 2.7 mm × 4.2 mm × 2.1 mm, matte tin-plated leads compliant with J-STD-002, polarity indicated by cathode band, and J-STD-020 moisture sensitivity level 1-eliminating pre-reflow baking requirements.
