Product details
Overview
ES2DAH from Taiwan Semiconductor is a 2 A, 200 V super fast recovery surface-mount rectifier in DO-214AC (SMA) package, featuring 35 ns reverse recovery time, 0.95 V forward voltage at 2 A, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in DC-DC converters and car lighting systems.
For engineers reviewing the ES2DAH datasheet, ES2DAH pinout, ES2DAH application, or ES2DAH equivalent, key selection criteria include peak reverse voltage (200 V), ultrafast switching performance (trr ≤ 35 ns), thermal resistance (RθJA = 75 °C/W), and automotive qualification status.
Technical Context
The ES2DAH employs a single-die, glass-passivated PN junction optimized for high-efficiency switching in medium-voltage power conversion. Its 200 V VRRM, 50 A IFSM, and 150 °C maximum junction temperature support robust operation under transient stress and elevated ambient conditions.
Designed for automated SMT assembly, the DO-214AC (SMA) package delivers low profile height (< 2.6 mm), matte tin-plated leads compliant with J-STD-002, and moisture sensitivity level 1 per J-STD-020 - enabling reflow compatibility without dry-pack requirements.
Key Specifications

| VRRM | 200 V - supports DC-DC stages operating up to 200 V reverse bias without breakdown |
| IF | 2 A continuous - rated for sustained conduction in compact power supplies and LED drivers |
| trr | 35 ns - enables high-frequency switching (>100 kHz) with minimal switching loss and EMI |
| VF | 0.95 V @ 2 A, 25°C - reduces conduction loss and thermal load in 12–48 V automotive systems |
| RθJA | 75 °C/W - defines thermal derating slope on standard FR-4 PCB with minimal copper area |
| Junction Temp | −55 to +150 °C - ensures operation across automotive under-hood environments |
| AEC-Q101 | Qualified - validated for automotive electronics per stress test requirements (HTOL, TC, HTRB) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH2R02DJF | Same DO-214AC package; 200 V VRRM; 30 ns trr; 0.92 V VF; no AEC-Q101 claim | Higher speed but lacks automotive qualification documentation | Preferred where ultra-low trr dominates over qualification requirements |
| ON Semi MUR220 | DO-214AC; 200 V VRRM; 35 ns trr; 0.97 V VF; AEC-Q101 qualified | Identical electrical specs and qualification; slightly higher VF | Drop-in alternative with identical automotive validation and thermal performance |
Compared with STTH2R02DJF, ES2DAH trades 5 ns faster recovery for formal AEC-Q101 certification; versus MUR220, it offers marginally lower forward drop while maintaining identical qualification, thermal, and packaging compatibility.

FAQ
What is the peak repetitive reverse voltage rating of the ES2DAH?
The ES2DAH has a peak repetitive reverse voltage (VRRM) rating of 200 V. This value is explicitly specified in the Absolute Maximum Ratings table for the ES2DAH variant within the ES2AAH–ES2JAH family datasheet. It defines the maximum reverse-biased voltage the device can block continuously without breakdown under normal operating conditions.
Is the ES2DAH qualified for automotive applications?
Yes, the ES2DAH is AEC-Q101 qualified. This qualification is confirmed in the FEATURES section of the official Taiwan Semiconductor datasheet and applies specifically to the ES2AAH–ES2JAH series, including ES2DAH. It validates the device for use in automotive electronic systems subject to rigorous stress testing for reliability and lifetime performance.
What is the forward voltage drop of the ES2DAH at rated current?
The ES2DAH exhibits a typical forward voltage (VF) of 0.95 V at 2 A forward current and 25°C junction temperature. This value is listed in the Electrical Specifications table under the ES2DAH column and reflects conduction loss under standard operating conditions used for efficiency calculations in power supply design.
What package type does the ES2DAH use, and what are its key mechanical attributes?
The ES2DAH uses the DO-214AC (SMA) surface-mount package. Key mechanical attributes include a low-profile height (<2.6 mm), matte tin-plated leads compliant with J-STD-002, UL 94V-0 flammability-rated molding compound, polarity indicated by cathode band, and moisture sensitivity level 1 per J-STD-020 - enabling direct reflow without baking.
What is the reverse recovery time of the ES2DAH, and how is it measured?
The ES2DAH has a maximum reverse recovery time (trr) of 35 ns. It is measured under the conditions: IF = 0.5 A, IR = 1.0 A, and Irr = 0.25 A, as defined in the Electrical Specifications table. This parameter quantifies switching speed and directly impacts high-frequency efficiency and EMI in SMPS designs.
