Product details

Overview

S15MLWHRVG from Taiwan Semiconductor is a 1.5A, 1000V repetitive peak reverse voltage (V_RRM) standard surface-mount silicon rectifier diode in SOD-123W package, designed for high-efficiency DC/DC conversion and switching-mode power supplies, with 50A peak surge current (I_FSM) and 175°C maximum junction temperature.

For engineers reviewing the S15MLWHRVG datasheet, S15MLWHRVG pinout, S15MLWHRVG application, or S15MLWHRVG equivalent, key selection criteria include verified V_RRM = 1000 V, I_F = 1.5 A continuous, forward voltage ≤1.10 V at 1.5 A / 25°C, thermal resistance R_θJA = 85°C/W on 5 mm × 5 mm Cu pad, and RoHS/halogen-free compliance per IEC 61249-2-21.

Technical Context

This single-die standard rectifier operates in unidirectional conduction mode with cathode-band polarity marking, optimized for high-frequency switching topologies where low forward voltage and robust surge capability are critical. Its SOD-123W package supports automated placement and meets J-STD-020 moisture sensitivity level 1.

Thermal performance is characterized with R_θJL = 29°C/W and R_θJC = 31°C/W, indicating efficient heat transfer to PCB leads and case under rated load. Reverse leakage remains ≤100 µA at 125°C and rated V_R, supporting stable operation in elevated ambient environments.

FAQ

What is the maximum repetitive peak reverse voltage (V_RRM) for S15MLWHRVG?

The S15MLWHRVG has a V_RRM of 1000 V, confirmed in the Absolute Maximum Ratings table of the official Taiwan Semiconductor datasheet (Version C2103). This rating allows the S15MLWHRVG to safely block reverse voltages up to 1000 V in continuous operation, making it suitable for high-voltage DC bus applications such as offline SMPS and industrial inverters where transient overvoltage margins are critical. The S15MLWHRVG maintains this rating across its full operating temperature range.

Does S15MLWHRVG support automated PCB assembly?

Yes, the S15MLWHRVG is qualified for automated placement per its SOD-123W package and J-STD-020 moisture sensitivity level 1 rating-no pre-bake required. Its matte tin-plated leads meet J-STD-002 solderability standards, and the compact footprint aligns with standard pick-and-place machine tooling. The S15MLWHRVG's polarity marking (cathode band) is clearly visible for optical recognition, ensuring reliable orientation during SMT assembly.

What is the forward voltage (V_F) of S15MLWHRVG at 1.5 A and 25°C?

The S15MLWHRVG exhibits a maximum forward voltage of 1.10 V at I_F = 1.5 A and T_J = 25°C, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and directly impacts conduction loss in power stages. At 125°C junction temperature, V_F drops to ≤1.05 V, reflecting the negative temperature coefficient typical of silicon PN junctions-this behavior is documented for the S15MLWHRVG in the same datasheet.

Is S15MLWHRVG RoHS and halogen-free compliant?

Yes, the S15MLWHRVG is RoHS compliant and halogen-free in accordance with IEC 61249-2-21, as explicitly stated in the Features section of the Taiwan Semiconductor datasheet. This compliance applies to all homogeneous materials in the device, including molding compound and lead finish. The S15MLWHRVG carries no exemptions and meets the full substance restrictions defined in Directive 2011/65/EU and subsequent amendments.

What is the thermal resistance from junction to ambient (R_θJA) for S15MLWHRVG?

The S15MLWHRVG has an R_θJA of 85°C/W when mounted on a standard test board with 5 mm × 5 mm copper pads, per the Thermal Performance section of the datasheet. This value assumes natural convection and defines the temperature rise above ambient per watt of dissipated power. For the S15MLWHRVG operating at full 1.5 A with V_F = 1.10 V, expected power dissipation is ~1.65 W, resulting in ~140°C junction-to-ambient rise-well within its 175°C T_Jmax limit when ambient is ≤35°C.
