Product details
Overview
ES15GLWH from Taiwan Semiconductor is a 1.5A, 400V super fast surface-mount rectifier in SOD-123W package, featuring glass passivated junction, AEC-Q101 qualification, and 35ns reverse recovery time. It serves as a freewheeling or snubber diode in automotive DC-DC converters and car lighting systems where high efficiency and thermal robustness are required.
For engineers reviewing the ES15GLWH datasheet, ES15GLWH pinout, ES15GLWH application, or ES15GLWH equivalent, key selection criteria include its 400V VRRM, 1.5A average forward current, 0.95V typical forward voltage at 1.5A/25°C, junction-to-lead thermal resistance of 26°C/W, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This device is a single-die, unidirectional silicon rectifier optimized for high-speed switching in power conversion stages. Its super fast recovery (trr ≤ 35ns) and low forward voltage reduce switching losses and conduction losses simultaneously.
The SOD-123W package enables automated placement and provides enhanced thermal performance over standard SOD-123 - with RθJL = 26°C/W and moisture sensitivity level 1 - making it suitable for reflow-soldered automotive PCBs operating up to 150°C junction temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L40S | Same SOD-123W package; 1.1A IF, 400V VRRM, 30ns trr, VF = 0.97V @ 1.1A | Lower current rating limits use in >1.1A continuous designs; better trr for ultra-high-frequency operation | Select when peak switching frequency exceeds 500kHz and average current ≤1.1A |
| ON Semi MUR120ES | SOD-123 package (not W); 1.0A IF, 200V VRRM, 35ns trr, VF = 0.92V @ 1.0A | Lower voltage rating and non-AEC-Q101; unsuitable for 400V automotive bus applications | Acceptable only for cost-sensitive industrial 200V designs without automotive qualification needs |
Compared with STTH1L40S and MUR120ES, the ES15GLWH uniquely combines 1.5A current handling, 400V rating, AEC-Q101 qualification, and SOD-123W thermal performance - making it the only option among the three qualified for 12V/48V dual-battery automotive power modules requiring sustained 1.5A conduction.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for ES15GLWH?
The ES15GLWH has a VRRM of 400 V, meaning it can block up to 400 volts in reverse bias without breakdown. This rating is confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2103), and is specific to ES15GLWH - distinct from ES15DLWH (200V) and ES15JLWH (600V). The 400V rating makes ES15GLWH suitable for 48V automotive bus interfaces and mid-voltage industrial SMPS.
Is ES15GLWH qualified for automotive applications?
Yes, ES15GLWH is AEC-Q101 qualified, as explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet. This qualification covers stress tests including HTGB, HTRB, TCT, and mechanical shock, validating its suitability for automotive power electronics such as body control modules and lighting drivers. The qualification applies specifically to ES15GLWH and other parts in the ES15xLWH family marked in the ordering code table.
What is the forward voltage (VF) of ES15GLWH at 1.5A and 25°C?
The forward voltage of ES15GLWH is 0.95 V maximum at 1.5A and 25°C, per the Electrical Specifications table. The typical value is 0.95 V, and the upper limit is specified as 1.30 V under those conditions. This VF directly impacts conduction loss and thermal design - for example, at 1.5A, worst-case power dissipation is 1.95 W, requiring appropriate PCB copper area per the thermal performance data (RθJL = 26°C/W).
Does ES15GLWH have a defined reverse recovery time (trr)?
Yes, ES15GLWH has a maximum reverse recovery time (trr) of 35 ns, measured under IF = 0.5A, IR = 1.0A, and Irr = 0.25A. This parameter is listed in the Electrical Specifications table and confirmed across all three variants (ES15DLWH/ES15GLWH/ES15JLWH). The 35 ns trr enables efficient operation in switching frequencies up to several hundred kHz, reducing switching losses in DC-DC converters.
What package does ES15GLWH use, and what are its key mechanical attributes?
ES15GLWH uses the SOD-123W package - a low-profile variant of SOD-123 with enhanced thermal performance. Key attributes include: matte tin-plated leads compliant with J-STD-002, UL 94V-0 flammability rating, cathode band polarity marking, 0.016g weight, and moisture sensitivity level 1 (no bake required). Dimensions and pad layout are specified in the Package Outline Dimensions section of the datasheet.
