Product details
Overview
S15MLW RVG from Taiwan Semiconductor is a 1.5A, 1000V repetitive peak reverse voltage (VRRM) surface-mount standard rectifier in SOD-123W package, optimized for high-efficiency DC-DC converters and switching-mode power supplies with 50A surge capability and 175°C max junction temperature.
For engineers reviewing the S15MLW RVG datasheet, S15MLW RVG pinout, S15MLW RVG application, or S15MLW RVG equivalent, key selection criteria include verified VRRM = 1000V, IF = 1.5A continuous, forward voltage ≤1.10V at 1.5A/25°C, thermal resistance RθJA = 85°C/W, and RoHS/halogen-free compliance per IEC 61249-2-21.
Technical Context
The S15MLW RVG is a single-die, single-phase standard silicon rectifier diode designed for unidirectional current flow in medium-voltage, medium-current power conversion stages. Its 1000V VRRM rating enables use in 800V-class bus systems, while its 50A IFSM supports robust transient handling during startup or fault conditions.
Thermal performance is defined for PCB mounting on 5mm × 5mm copper pads, with RθJL = 29°C/W and RθJC = 31°C/W confirming efficient heat transfer to lead and case. Junction capacitance is specified at 10pF (1MHz, 4V reverse bias), supporting stable high-frequency operation without excessive capacitive loading.

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | VRRM = 600V, IF = 1A, VF ≈ 1.15V @ 1A/25°C, SOD-123 package | Limited to ≤400V DC bus; lower surge rating (30A) | Select only if system VRMS < 420V and peak current < 30A; not suitable for 800V-class designs |
| ON Semi MUR120RLG | VRRM = 200V, IF = 1A, ultrafast recovery (trr = 75ns), DO-41 package | Lower voltage rating; through-hole mounting; faster switching but higher VF | Prefer for low-VRMS, high-frequency flyback snubbers where speed outweighs voltage headroom |
Compared with STTH1L06S and MUR120RLG, the S15MLW RVG uniquely delivers 1000V blocking with 1.5A current and SMD compatibility-enabling higher-voltage, higher-power density designs without layout redesign or thermal derating penalties.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) for the S15MLW RVG?
The S15MLW RVG has a guaranteed VRRM of 1000V, confirmed in the Absolute Maximum Ratings table across all production lots. This rating is validated under standard test conditions (TA = 25°C) and supports design margins for 800V DC bus applications. The S15MLW RVG is the highest-voltage variant in the S15xLW series, distinct from S15DLW (200V) and S15KLW (800V).
Does the S15MLW RVG have a specified forward voltage (VF) at 1.5A and 125°C?
Yes, the S15MLW RVG specifies VF ≤ 1.05V at IF = 1.5A and TJ = 125°C, per the Electrical Specifications table. This value reflects real-world conduction loss under elevated temperature conditions typical in enclosed power supplies. The S15MLW RVG maintains lower VF than comparable 1000V rectifiers due to optimized die metallization and thermal design.
Is the S15MLW RVG RoHS and halogen-free compliant?
Yes, the S15MLW RVG is fully RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section. This compliance applies to all materials-including molding compound, lead finish, and internal die attach-ensuring suitability for export to EU, Japan, and South Korea markets. The S15MLW RVG carries no exemptions and meets strict substance restrictions without trade-offs in thermal or electrical performance.
What is the moisture sensitivity level (MSL) of the S15MLW RVG?
The S15MLW RVG has a moisture sensitivity level of MSL 1 per J-STD-020, meaning it may be stored indefinitely at ≤30°C/60% RH without baking prior to reflow soldering. This eliminates pre-reflow bake cycles in manufacturing, reducing process time and cost. The S15MLW RVG's SOD-123W package construction and dry-packaging ensure this MSL rating is maintained across full production lots.
What thermal resistance values are specified for the S15MLW RVG?
The S15MLW RVG specifies RθJA = 85°C/W, RθJL = 29°C/W, and RθJC = 31°C/W, all measured on a standardized 5mm × 5mm copper pad PCB. These values define thermal limits for layout design: RθJA governs ambient-to-junction rise under natural convection, while RθJL confirms safe lead-to-junction transfer during reflow. The S15MLW RVG's thermal metrics are consistent across voltage variants in the family.
