Product details
Overview
ES15JLWH from Taiwan Semiconductor is a 600 V, 1.5 A super fast surface-mount rectifier in SOD-123W package, featuring 1.18 V forward voltage at 1.5 A and 25°C, 35 ns reverse recovery time, and AEC-Q101 qualification for automotive-grade reliability. It serves as a freewheeling or snubber diode in high-efficiency DC-DC converters and car lighting systems.
For engineers reviewing the ES15JLWH datasheet, ES15JLWH pinout, ES15JLWH application, or ES15JLWH equivalent, key selection criteria include its 600 V repetitive peak reverse voltage, low-profile SOD-123W thermal performance (RθJA = 76°C/W), junction capacitance of 20 pF at 1 MHz/4 V, and compliance with JESD201 Class 2 whisker resistance and J-STD-020 Level 1 moisture sensitivity.
Technical Context
The ES15JLWH is a single-die, glass-passivated silicon rectifier optimized for high-speed switching in automotive power supplies. Its 600 V VRRM, 40 A IFSM, and 150°C maximum junction temperature support robust operation under transient overloads and elevated ambient conditions.
Thermal design is enabled by RθJL = 26°C/W and RθJC = 27°C/W on standard 5 mm × 5 mm Cu pads, while its 1.70 V max forward voltage at 1.5 A/25°C ensures predictable conduction loss in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 600 V - supports input rails up to 420 V RMS in AC-DC front-ends or 600 V bus transients in automotive 48V systems |
| IF | 1.5 A continuous - rated for sustained conduction in DC-DC output stages and LED driver freewheel paths |
| trr | ≤35 ns - enables high-frequency switching (>100 kHz) with minimal switching loss and EMI generation |
| VF @ 1.5A, 25°C | 1.18 V typ / 1.70 V max - defines conduction loss budget (1.77–2.55 W dissipation at full load) |
| CJ @ 1 MHz, 4 V | 20 pF - limits capacitive coupling in snubber networks and high-side gate drive isolation |
| RθJA | 76°C/W - establishes thermal rise (114°C at 1.5 A, 1.70 V) on standard FR-4 PCB without heatsink |
Pinout & Package
Package: SOD-123W - low-profile (1.0 mm height), surface-mount plastic case with matte tin-plated leads, UL 94V-0 rated molding compound, cathode band polarity marking, and 0.016 g mass.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super fast rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 600 V VRRM, 1 A IF, 50 ns trr, DO-214AC package | Lower current rating and slower recovery limit use in >1 A or >200 kHz designs | Select when board space allows larger DO-214AC and 1 A rating suffices |
| ON Semi MUR160 | 600 V VRRM, 1 A IF, 60 ns trr, DO-41 through-hole | Through-hole mounting and higher VF (~1.3 V) increase assembly cost and conduction loss | Prefer only for legacy through-hole designs where rework to SMD is not feasible |
Compared with STTH1L06S and MUR160, the ES15JLWH delivers 50% higher current handling in a low-profile SMD package with 43% faster recovery, making it optimal for next-generation automotive DC-DC and LED driver modules requiring compact, high-efficiency rectification.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the ES15JLWH?
The ES15JLWH has a maximum repetitive peak reverse voltage (VRRM) of 600 V, verified per Taiwan Semiconductor's A2103 datasheet. This rating allows the ES15JLWH to safely block transients in 48V automotive systems and withstand load dump events up to ISO 7637-2 Pulse 5a. The 600 V value is specific to the ES15JLWH variant and differs from lower-voltage family members like ES15DLWH (200 V).
Is the ES15JLWH suitable for automotive applications?
Yes, the ES15JLWH is AEC-Q101 qualified and explicitly designed for automotive use, including DC-DC converters, LED lighting, and snubber circuits. Its glass-passivated junction, JESD201 Class 2 whisker resistance, and -55°C to +150°C operating range meet stringent automotive reliability requirements. The ES15JLWH datasheet confirms qualification testing per AEC-Q101 Rev D standards.
What is the forward voltage (VF) of the ES15JLWH at 1.5 A and 25°C?
The ES15JLWH exhibits a typical forward voltage of 1.18 V and a maximum of 1.70 V at 1.5 A and 25°C, per the manufacturer's electrical specifications table. At 125°C, VF drops to 0.97 V typical / 1.30 V max, reflecting silicon's negative temperature coefficient. These values are measured under pulsed conditions (PW = 0.3 ms) to avoid self-heating effects.
What package does the ES15JLWH use, and what are its key mechanical features?
The ES15JLWH uses the SOD-123W surface-mount package: low-profile (1.0 mm height), UL 94V-0 rated molding compound, matte tin-plated leads compliant with J-STD-002, and cathode band polarity marking. Its 0.016 g mass and 5 mm × 5 mm thermal pad compatibility enable high-density, thermally efficient PCB layouts-critical for automotive LED drivers and compact DC-DC modules.
What is the reverse recovery time (trr) of the ES15JLWH, and how is it tested?
The ES15JLWH has a maximum reverse recovery time (trr) of 35 ns, measured under specified test conditions: IF = 0.5 A, IR = 1.0 A, and IRR = 0.25 A. This parameter is critical for minimizing switching losses in high-frequency power converters. The 35 ns value is confirmed in the "Electrical Specifications" section of the official Taiwan Semiconductor datasheet (Version A2103) and applies exclusively to the ES15JLWH variant.
