Taiwan Semiconductor Corporation S15JLWH

Overview

S15JLWH from Taiwan Semiconductor is a 1.5A, 600V standard surface-mount silicon rectifier diode in SOD-123W package, AEC-Q101 qualified, with 50A peak surge current rating and 175°C maximum junction temperature-used in automotive DC-DC converters and snubber circuits.

For engineers reviewing the S15JLWH datasheet, S15JLWH pinout, S15JLWH application, or S15JLWH equivalent, key selection criteria include repetitive peak reverse voltage (600 V), forward voltage at 1.5 A (≤1.10 V @ 25°C), thermal resistance (R_θJA = 85 °C/W), moisture sensitivity level (MSL 1), and AEC-Q101 qualification for automotive reliability.

Technical Context

The S15JLWH is a single-die, unidirectional standard recovery rectifier optimized for high-efficiency power conversion in space-constrained layouts. Its SOD-123W package supports automated placement and meets JESD201 Class 2 whisker resistance and UL 94V-0 flammability requirements.

Electrical behavior is defined by low forward voltage (VF ≤ 1.10 V at IF = 1.5 A, TJ = 25°C), low leakage (IR ≤ 1 µA at VR = 600 V, TJ = 25°C), and junction capacitance of 10 pF at 1 MHz/4 V-enabling stable performance in snubbers and mid-voltage DC-DC stages.

FAQ

What is the peak repetitive reverse voltage rating of the S15JLWH?

The S15JLWH has a peak repetitive reverse voltage (V_RRM) rating of 600 V. This value is specified in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version A2103) and defines the maximum reverse-biased voltage the device can block continuously without breakdown. It is critical for selecting appropriate safety margins in 48 V and 60 V automotive power systems.

Is the S15JLWH suitable for automotive applications?

Yes, the S15JLWH is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and lighting modules. The qualification covers stress tests such as temperature cycling, high-temperature reverse bias, and mechanical shock-ensuring reliability under real-world vehicle operating conditions. The S15JLWH datasheet explicitly lists "Automotive application" and "Car lighting" under Applications.

What is the forward voltage drop of the S15JLWH at 1.5 A and 25°C?

The forward voltage drop (V_F) of the S15JLWH is guaranteed ≤1.10 V at 1.5 A and 25°C, per the Electrical Specifications table. This maximum value reflects worst-case conduction loss under nominal conditions and is measured using pulse testing (PW = 0.3 ms). At elevated temperatures (125°C), V_F remains ≤1.05 V, supporting stable performance in thermally demanding environments.

What package type does the S15JLWH use, and what are its key mechanical properties?

The S15JLWH uses the SOD-123W surface-mount package. Key mechanical properties include matte tin-plated leads compliant with J-STD-002 solderability, UL 94V-0 molding compound, JESD201 Class 2 whisker resistance, polarity indicated by cathode band, and moisture sensitivity level (MSL) 1-meaning no bake requirement before reflow. Its approximate weight is 0.019 g.

Does the S15JLWH have halogen-free and RoHS-compliant construction?

Yes, the S15JLWH is both RoHS compliant and halogen-free per IEC 61249-2-21. These environmental attributes are explicitly stated in the FEATURES section of the Taiwan Semiconductor datasheet (Version A2103) and verified through material declarations. Halogen-free status ensures absence of brominated and chlorinated flame retardants, supporting safer recycling and regulatory compliance in global markets.
