Product details

Overview

ES15GLW from Taiwan Semiconductor is a 1.5A, 400V super fast surface-mount rectifier in SOD-123W package, featuring 0.95V max forward voltage at 1.5A/25°C, 35ns reverse recovery time, and 21pF junction capacitance. It serves as a freewheeling or output rectifier in high-frequency DC-DC converters and switching inverters.

For engineers reviewing the ES15GLW datasheet, ES15GLW pinout, ES15GLW application, or ES15GLW equivalent, key selection criteria include V_RRM = 400V, I_F = 1.5A continuous, trr ≤ 35ns, thermal resistance R_θJA = 76°C/W, and SOD-123W footprint compatibility with automated placement.

Technical Context

The ES15GLW is a single-die, glass-passivated silicon PN junction rectifier optimized for high-speed switching operation. Its 400V repetitive peak reverse voltage and 35ns reverse recovery time enable efficient operation in 100–500kHz SMPS topologies.

Thermal performance is defined by R_θJL = 26°C/W and R_θJA = 76°C/W on a 5mm × 5mm Cu pad PCB - critical for thermal management in compact power stages where lead temperature must stay below 150°C under 1.5A load.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	400 V - supports input/output isolation up to 400V DC bus in industrial DC-DC and PV inverter stages
I_F	1.5 A continuous - delivers rated current without derating at T_A ≤ 75°C on standard PCB layout
trr	≤35 ns - minimizes switching loss and EMI in high-frequency flyback and forward converters
V_F @ 1.5A, 25°C	0.95 V max - reduces conduction loss to <1.4W per device at full load, improving system efficiency
C_J	21 pF - limits capacitive coupling noise and enables stable gate drive in synchronous rectifier auxiliary paths
R_θJA	76 °C/W - requires ≤75°C ambient or heatsinking to maintain T_J ≤ 150°C at full I_F

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 MUR1540	V_RRM = 400V, I_F = 1.5A, trr = 35ns, but in DO-41 package (larger, axial lead)	Requires through-hole assembly and larger PCB area; not compatible with SOD-123W reflow footprint	Select when legacy through-hole design or higher surge robustness (I_FSM = 50A) is prioritized over size and automation.
Vishay VS-1N5819HM3/85A	V_RRM = 40V only, Schottky architecture, V_F ≈ 0.45V, but unsuitable above ~100kHz due to soft recovery	Limited to low-voltage, low-noise applications (e.g., USB power rails); cannot replace ES15GLW in 400V systems	Choose only for sub-40V, ultra-low-V_F needs where reverse voltage stress is negligible.

Compared with MUR1540 and VS-1N5819HM3/85A, the ES15GLW uniquely combines 400V blocking, 35ns speed, SOD-123W surface-mount compatibility, and 1.5A rating - making it optimal for space-constrained, high-frequency industrial and telecom power supplies where leaded alternatives add cost and volume.

FAQ

What is the maximum junction temperature rating for the ES15GLW?

The ES15GLW has a maximum junction temperature (T_J) of +150°C, verified per absolute maximum ratings in the official datasheet. This allows reliable operation in high-ambient environments such as enclosed industrial power supplies or automotive under-hood auxiliary circuits - provided thermal design maintains T_J ≤ 150°C using the specified R_θJA = 76°C/W on a 5mm × 5mm Cu pad. The ES15GLW must not be operated beyond this limit to ensure long-term reliability.

Does the ES15GLW have a halogen-free construction?

Yes, the ES15GLW is halogen-free in compliance with IEC 61249-2-21, and also RoHS compliant. This is confirmed in the "Features" section of the official Taiwan Semiconductor datasheet (Version C2103). The molding compound and plating materials meet both environmental standards, making the ES15GLW suitable for export to regulated markets including the EU and Japan without restriction.

What is the reverse recovery time (trr) specification for the ES15GLW?

The ES15GLW 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 value is explicitly listed in the "ELECTRICAL SPECIFICATIONS" table of the Taiwan Semiconductor datasheet. The 35 ns t_rr enables clean commutation in high-frequency switching applications such as 300kHz flyback converters, minimizing switching loss and associated EMI generation in the ES15GLW's operational envelope.

Is the ES15GLW pin-compatible with other parts in the ES15xLW series?

Yes, all ES15xLW variants - including ES15DLW (200V), ES15GLW (400V), and ES15JLW (600V) - share identical SOD-123W package dimensions, pinout, and mechanical footprint. They differ only in V_RRM, forward voltage, and junction capacitance. Therefore, the ES15GLW can be substituted within the same family without PCB layout changes, provided the 400V rating meets system voltage stress requirements and thermal design accommodates its specific V_F and C_J.

What is the marking code printed on the ES15GLW device body?

The ES15GLW is marked with "ES15G" on its top surface, as specified in the "ABSOLUTE MAXIMUM RATINGS" table of the Taiwan Semiconductor datasheet. This 5-character marking - along with date code (YW) and factory code (F) - enables visual identification and traceability. The "G" suffix directly corresponds to the 400V V_RRM rating and distinguishes it from ES15D (200V) and ES15J (600V) variants in the same SOD-123W package.
