Product details

Overview

ES15DLW from Taiwan Semiconductor is a 1.5A, 200V super fast surface-mount rectifier in SOD-123W package, featuring 0.85V forward voltage at 1.5A/25°C, 35ns reverse recovery time, and 40A peak surge current. It serves as a freewheeling or output rectifier in high-frequency switching power supplies.

For engineers reviewing the ES15DLW datasheet, ES15DLW pinout, ES15DLW application, or ES15DLW equivalent, key selection criteria include V_RRM = 200V, I_F = 1.5A, t_rr ≤ 35ns, thermal resistance R_θJA = 76°C/W, and SOD-123W footprint compatibility with automated placement.

Technical Context

The ES15DLW employs a single-die silicon junction with glass passivation for stable high-speed switching performance. Its 200V repetitive peak reverse voltage and 35ns reverse recovery time enable efficient operation in DC-DC converters operating above 100kHz.

Thermal design is supported by R_θJL = 26°C/W and R_θJC = 27°C/W, measured on a 5mm × 5mm copper pad PCB. The device operates across –55°C to +150°C junction temperature range with moisture sensitivity level 1 per J-STD-020.

Equivalent & Alternatives

The following parts are listed as comparable options for similar super fast rectifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
ON Semiconductor MUR1520	V_RRM = 200V, I_F = 1.5A, t_rr = 35ns, but in DO-41 through-hole package (not SMD)	Requires PCB redesign for through-hole mounting; unsuitable for automated SMT lines	Select only if legacy through-hole assembly is mandated and board real estate is not constrained
Vishay VS-1.5EWH02-M3	V_RRM = 200V, I_F = 1.5A, t_rr = 25ns, SOD-123W package, but VF = 0.92V @ 1.5A/25°C	Lower t_rr improves high-frequency efficiency but higher V_F increases conduction loss at medium loads	Prefer for >1MHz designs where switching loss dominates; ES15DLW better for 100–500kHz with balanced loss trade-off

Compared with MUR1520 and VS-1.5EWH02-M3, the ES15DLW delivers optimal balance of low V_F (0.85V), fast t_rr (35ns), and SOD-123W SMT compatibility-making it ideal for cost-sensitive, high-volume DC-DC converter designs requiring no layout change from standard footprint.

FAQ

What is the maximum junction temperature rating for the ES15DLW?

The ES15DLW has a maximum junction temperature (T_J) rating of +150°C, with operational range from –55°C to +150°C. This allows reliable use in enclosed power supplies and thermally demanding environments. Derating curves confirm 1.5A average forward current is maintainable up to 75°C case temperature. Thermal design must account for R_θJA = 76°C/W on standard PCB layout.

Does the ES15DLW have a specified reverse recovery time, and how is it measured?

Yes, the ES15DLW has a maximum reverse recovery time (t_rr) of 35 ns, measured under conditions of I_F = 0.5A, I_R = 1.0A, and I_rr = 0.25A. This parameter is critical for minimizing switching losses in high-frequency converters. The value is verified per JEDEC test methods and applies directly to the ES15DLW variant-not extrapolated from other family members.

Is the ES15DLW RoHS and halogen-free compliant?

Yes, the ES15DLW is fully RoHS compliant per EU Directive 2011/65/EU and halogen-free per IEC 61249-2-21. These compliance statements are confirmed in the official Taiwan Semiconductor datasheet revision C2103 and verified through material declarations. No exemptions are applied; lead content is below 1000 ppm threshold.

What is the marking code printed on the ES15DLW device body?

The ES15DLW is marked with "ES15D" on its surface, followed by date code and factory identifier (e.g., YW and F). This marking distinguishes it from higher-voltage variants: ES15GLW (ES15G) and ES15JLW (ES15J). Visual identification via this code is essential for correct variant selection during manual inspection or automated optical recognition.

What is the typical forward voltage of the ES15DLW at elevated temperature?

At 1.5A and 125°C junction temperature, the ES15DLW exhibits a typical forward voltage (V_F) of 0.73V, with a maximum of 0.80V. This represents a reduction from the 25°C value (0.85V), due to negative temperature coefficient of silicon diodes. Designers should use the 125°C value for worst-case thermal analysis in high-ambient applications.
