Product details
Overview
ES2DFSH from Taiwan Semiconductor is a 2 A, 200 V super fast surface-mount rectifier in SOD-128 package, featuring 35 ns reverse recovery time, 0.88 V forward voltage at 2 A/25°C, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in DC/DC converters where low conduction loss and fast switching are critical.
For engineers reviewing the ES2DFSH datasheet, ES2DFSH pinout, ES2DFSH application, or ES2DFSH equivalent, key selection criteria include its 200 V VRRM, 50 A IFSM surge rating, 24 °C/W RθJL, glass-passivated junction, and SOD-128 thermal performance on PCB-mounted 5 mm × 5 mm copper pads.
Technical Context
The ES2DFSH is a single-die, unidirectional silicon rectifier optimized for high-frequency switching applications. Its super fast recovery (trr ≤ 35 ns) and low Qrr minimize switching losses in hard-switched topologies, while the glass-passivated junction ensures stable operation under thermal cycling and humidity stress.
Designed for surface-mount assembly with matte tin-plated leads (J-STD-002 compliant), it supports automated placement and reflow soldering. The SOD-128 package delivers 72 °C/W RθJA on standard test board and operates across –55°C to +150°C junction temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 200 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in DC/DC flyback or buck snubber circuits |
| IF | 2 A continuous - Rated average forward current at TL = 115°C; determines steady-state power dissipation capability |
| trr | ≤ 35 ns - Reverse recovery time at IF = 0.5 A, IR = 1.0 A, Irr = 0.25 A; enables >1 MHz switching without excessive turn-off loss |
| VF | 0.88 V @ 2 A, 25°C - Low forward drop reduces conduction loss and thermal load in high-duty-cycle applications |
| RθJL | 24 °C/W - Junction-to-lead thermal resistance; enables direct heat transfer to PCB copper, supporting compact thermal design |
| IFSM | 50 A @ 8.3 ms - Non-repetitive surge current rating; withstands inrush and fault transients in automotive power supplies |
| Junction Temp | –55°C to +150°C - Full operational range supports under-hood automotive environments and industrial ambient extremes |
Pinout & Package
SOD-128 is a low-profile, surface-mount plastic package with gull-wing leads. Cathode polarity is marked by a band on the device body. Leads are matte tin-plated and solderable per J-STD-002.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); must handle full 2 A DC and 50 A surge |
| Cathode | Forward current exit / reverse blocking terminal | Connected to higher-potential rail (e.g., output capacitor positive); blocks up to 200 V reverse bias with <1 µA leakage at 25°C |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive electronics use, including temperature cycling, HTRB, and ESD testing per stress test plan |
| Glass passivated junction | Eliminates risk of junction corrosion and parameter drift under humid or contaminated conditions |
| Low profile SOD-128 package | Height ≤ 1.1 mm enables ultra-thin power modules and space-constrained automotive ECUs |
| Moisture sensitivity level 1 | No floor life limitation or baking required before reflow-reduces manufacturing overhead and handling risk |
| Halogen-free & RoHS compliant | Meets IEC 61249-2-21 and EU Directive 2011/65/EU; supports green manufacturing and end-of-life recycling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-ES2D-M3/5BT | Same SOD-128 package, 200 V VRRM, but trr = 50 ns (vs. 35 ns); VF = 0.92 V @ 2 A/25°C | Higher trr increases switching loss above 300 kHz; suitable for <300 kHz flyback or linear-regulated supplies | Select when cost sensitivity outweighs high-frequency efficiency needs and AEC-Q101 is not required |
| ON Semiconductor MUR220SFT1G | SOD-128, 200 V, but trr = 35 ns and VF = 0.97 V @ 2 A/25°C; no AEC-Q101 qualification | Lacks automotive qualification; acceptable for industrial/commercial DC/DC where qualification is not mandated | Choose when automotive qualification is unnecessary and slightly higher VF is tolerable for thermal budget |
Compared with VS-ES2D-M3/5BT and MUR220SFT1G, the ES2DFSH delivers superior high-frequency efficiency due to its 35 ns trr and 0.88 V VF, while only ES2DFSH carries AEC-Q101 certification-making it the sole choice for automotive-critical freewheeling and snubber roles.

FAQ
What is the maximum junction temperature rating for the ES2DFSH?
The ES2DFSH has a maximum junction temperature (TJ) rating of +150°C, with a full operational range from –55°C to +150°C. This specification allows the ES2DFSH to operate reliably in under-hood automotive environments and high-ambient industrial settings without derating below 2 A continuous current when properly mounted on a 5 mm × 5 mm copper pad.
Is the ES2DFSH pin-compatible with other devices in the ES2xFSH series?
Yes-the ES2DFSH shares identical SOD-128 package dimensions, lead pitch, and cathode-band polarity marking with ES2BFSH, ES2GFSH, and ES2JFSH. All variants use the same footprint and thermal pad layout, enabling voltage-scaling design reuse across 100 V to 600 V ratings without PCB changes.
Does the ES2DFSH require moisture sensitivity handling prior to reflow?
No-the ES2DFSH is rated at Moisture Sensitivity Level (MSL) 1 per J-STD-020, meaning it has unlimited floor life and does not require dry-packaging, baking, or special handling before reflow soldering. This simplifies manufacturing logistics and eliminates yield risk from moisture-related popcorning.
What is the reverse recovery time (trr) specification for the ES2DFSH, and under what test conditions?
The ES2DFSH 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 value is confirmed in the official Taiwan Semiconductor datasheet and reflects the device's super fast switching performance essential for minimizing turn-off loss in high-frequency power converters.
Can the ES2DFSH be used as a direct replacement for the ES2BFSH in a 100 V design?
No-the ES2DFSH is rated for 200 V VRRM, whereas the ES2BFSH is rated for 100 V. Substituting ES2DFSH into a 100 V design is electrically safe but may incur unnecessary cost and margin; however, substituting ES2BFSH into a 200 V circuit violates absolute maximum ratings and risks catastrophic failure. Always match VRRM to system peak reverse voltage requirements.
