Product details
Overview
S15DLW RVG from Taiwan Semiconductor is a 1.5A, 200V standard surface-mount silicon rectifier diode in SOD-123W package, featuring low forward voltage (1.05 V max at 1.5 A, 25°C), high surge capability (50 A IFSM), and 175°C maximum junction temperature - used in DC-DC converters and switching-mode power supplies.
For engineers reviewing the S15DLW RVG datasheet, S15DLW RVG pinout, S15DLW RVG application, or S15DLW RVG equivalent, key selection criteria include repetitive peak reverse voltage (200 V), thermal resistance (RθJA = 85 °C/W), moisture sensitivity level (MSL 1), RoHS/halogen-free compliance, and SOD-123W footprint compatibility with automated placement.
Technical Context
The S15DLW RVG is a single-die, standard recovery rectifier optimized for medium-voltage, medium-current switching power applications. It operates across -55°C to +175°C junction temperature range and delivers stable reverse leakage (<1 µA at 25°C, <100 µA at 125°C) under rated 200 V reverse bias.
Its SOD-123W package provides enhanced thermal performance (RθJL = 29 °C/W) over standard SOD-123, with matte tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance - critical for industrial and automotive-grade reliability.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR120SFT1G | 200 V VRRM, 1.0 A IF, faster recovery (75 ns), TO-277 package | Lower current rating; suited for lower-power, higher-frequency designs | Select when faster switching and smaller reverse recovery charge are prioritized over current capacity |
| Vishay VS-1N4007TR-M3/54 | 1000 V VRRM, 1.0 A IF, standard recovery, DO-214AC package | Higher voltage rating but lower current and larger footprint; not MSL 1 | Choose only if >200 V standoff is required and thermal constraints allow larger package |
Compared with MUR120SFT1G and VS-1N4007TR-M3/54, the S15DLW RVG uniquely balances 1.5 A current, 200 V rating, SOD-123W compactness, MSL 1 handling, and 175°C operation - making it optimal for space-constrained, thermally demanding, high-volume industrial power stages.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the S15DLW RVG?
The S15DLW RVG has a VRRM of 200 V, verified per Taiwan Semiconductor's C2103 datasheet. This rating ensures safe operation under transient voltage spikes up to 200 V in continuous reverse bias. The S15DLW RVG is not rated for higher voltages - selecting S15GLW (400 V) or above is required for elevated reverse stress conditions.
Does the S15DLW RVG have moisture sensitivity level (MSL) certification?
Yes, the S15DLW RVG is rated MSL 1 per J-STD-020, confirmed in the official datasheet. This means the S15DLW RVG can be stored indefinitely at ambient conditions and placed directly into reflow without baking - a key advantage for high-throughput SMT lines handling industrial-grade components.
What is the forward voltage (VF) of the S15DLW RVG at full rated current?
At 1.5 A and 25°C, the S15DLW RVG exhibits a maximum forward voltage of 1.10 V, with typical value of 0.98 V. At 125°C, VF drops to ≤1.05 V due to semiconductor physics - this behavior is documented in the electrical specifications table of the S15DLW RVG datasheet and impacts thermal design margin.
Is the S15DLW RVG halogen-free and RoHS compliant?
Yes, the S15DLW RVG meets both RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21, as explicitly stated in the "Features" section of the official datasheet. These certifications apply to the completed S15DLW RVG device, including molding compound and lead finish.
What is the thermal resistance from junction to ambient (RθJA) for the S15DLW RVG?
The S15DLW RVG has an RθJA of 85 °C/W when mounted on a 5 mm × 5 mm copper pad, per the thermal performance section of its datasheet. This value assumes standard JEDEC test board conditions and must be adjusted for actual PCB layout - the S15DLW RVG's RθJA directly informs heatsinking and derating decisions in thermal design.
