Product details
Overview
ES2GFSH from Taiwan Semiconductor is a 2 A, 400 V super fast surface-mount rectifier in SOD-128 package, featuring 35 ns reverse recovery time, 0.97 V forward voltage at 2 A/25°C, and AEC-Q101 qualification for automotive-grade reliability-used in DC/DC converter freewheeling paths and snubber circuits.
For engineers reviewing the ES2GFSH datasheet, ES2GFSH pinout, ES2GFSH application, or ES2GFSH equivalent, key selection criteria include peak reverse voltage (400 V), thermal resistance (RθJL = 24 °C/W), junction temperature range (–55 to +150 °C), and low-profile SOD-128 mounting compatibility with automated assembly.
Technical Context
The ES2GFSH is a single-die, glass-passivated silicon rectifier optimized for high-speed switching in power conversion stages. Its 35 ns trr and low Qrr support efficient operation in high-frequency DC/DC topologies, while the 400 V VRRM rating targets mid-voltage industrial and automotive auxiliary supplies.
Thermal performance is defined by RθJL = 24 °C/W and RθJA = 72 °C/W on a 5 mm × 5 mm Cu pad PCB, enabling 2 A continuous conduction without forced cooling. The device's cathode-band polarity marking and matte tin-plated leads comply with J-STD-002 solderability and JESD201 Class 2 whisker requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 400 V - supports input rails up to 280 V DC or 400 V peak AC-derived supplies |
| IF | 2 A continuous - delivers rated current with ≤0.97 V drop at 25°C, limiting conduction loss to <1.94 W |
| trr | 35 ns - enables switching frequencies >500 kHz with minimal turn-off loss and EMI |
| CJ | 27 pF at 1 MHz / 4 V - reduces capacitive coupling noise in high-dv/dt snubber applications |
| TJ max | +150 °C - allows operation in under-hood automotive environments and sealed industrial enclosures |
| RθJL | 24 °C/W - permits direct heat transfer to PCB copper, supporting compact layout without heatsinks |
Pinout & Package
Package: SOD-128 - low-profile (1.1 mm height), surface-mount plastic case with matte tin-plated leads, UL 94V-0 rated molding compound, and cathode band polarity indicator.

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-277A package (larger footprint, higher RθJA) | Requires PCB redesign due to different outline and thermal pad layout | Prefer when higher surge rating (IFSM = 75 A) is critical and board space allows |
| ON Semi MUR240 | 400 V VRRM, 2 A IF, 50 ns trr, DO-214AC package (higher profile, no AEC-Q101) | Lacks automotive qualification and has slower recovery, limiting high-frequency use | Select only for cost-sensitive non-automotive industrial applications where 50 ns trr suffices |
Compared with STTH2R04 and MUR240, the ES2GFSH provides AEC-Q101 compliance and SOD-128 low-profile integration in a single package-enabling automotive-grade reliability and space-constrained layouts without sacrificing 35 ns speed or thermal performance.

FAQ
What is the peak repetitive reverse voltage rating of the ES2GFSH?
The ES2GFSH has a peak repetitive reverse voltage (VRRM) rating of 400 V. This value is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version B2103), and defines the maximum reverse-biased voltage the device can block continuously without breakdown. It is not interchangeable with other variants in the ES2xFSH family-ES2BFSH is 100 V, ES2DFSH is 200 V, and ES2JFSH is 600 V.
Does the ES2GFSH meet automotive qualification standards?
Yes, the ES2GFSH is explicitly AEC-Q101 qualified, as stated in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including high-temperature operating life, temperature cycling, and unbiased highly accelerated stress testing-validating its suitability for automotive power electronics such as body control modules and ADAS power supplies.
What is the forward voltage drop of the ES2GFSH at 2 A and 25°C?
The forward voltage drop (VF) of the ES2GFSH is 0.97 V typical at 2 A and 25°C, with a maximum of 1.30 V under the same conditions. This value is specified in the ELECTRICAL SPECIFICATIONS table for ES2GFSH under "IF = 2A, TJ = 25°C", and directly impacts conduction loss calculation (Pcond ≈ IF × VF) in thermal design.
What package type does the ES2GFSH use, and what are its mechanical highlights?
The ES2GFSH uses the SOD-128 surface-mount package: low-profile (1.1 mm max height), UL 94V-0 compliant molding compound, matte tin-plated leads meeting J-STD-002 solderability, and cathode band polarity marking. Its mechanical data confirms a weight of ~0.028 g and compliance with JESD201 Class 2 whisker resistance-critical for automated assembly and long-term field reliability.
What is the reverse recovery time (trr) specification for the ES2GFSH?
The reverse recovery time (trr) of the ES2GFSH is 35 ns maximum, measured under IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A conditions. This parameter is listed in the ELECTRICAL SPECIFICATIONS table and reflects the device's ability to rapidly transition from conduction to blocking state-key for minimizing switching loss and EMI in high-frequency DC/DC converters.
