Product details
Overview
S15JLW from Taiwan Semiconductor is a 1.5A, 600V standard surface-mount silicon rectifier diode in SOD-123W package, designed for DC-to-DC converters and switching-mode power supplies where compact size, high surge capability (50A IFSM), and low forward voltage (1.05V max at 1.5A, 25°C) are critical.
For engineers reviewing the S15JLW datasheet, S15JLW pinout, S15JLW application, or S15JLW equivalent, key selection factors include its 600V VRRM rating, 175°C maximum junction temperature, moisture sensitivity level 1 compliance, RoHS/halogen-free status, and SOD-123W thermal performance (RθJA = 85°C/W on 5mm × 5mm Cu pad).
Technical Context
The S15JLW is a single-die, planar-junction standard rectifier optimized for medium-voltage, medium-current switching applications. Its 600V repetitive peak reverse voltage (VRRM) and 1.5A average forward current (IF) define its operating envelope, while the 50A non-repetitive surge rating supports transient load conditions in SMPS front-end stages.
Thermal design is enabled by its SOD-123W package with RθJL = 29°C/W and RθJC = 31°C/W, verified on standardized PCB test boards. Electrical behavior includes low leakage (≤100 µA at 125°C, rated VR) and stable forward voltage across temperature (0.87–1.05V at 1.5A), supporting predictable conduction loss modeling.
Key Specifications

Applications
| DC-to-DC Converter Output Rectification | Switching Mode Inverter Freewheeling |
|---|---|
Use Scenario: Secondary-side rectification in isolated 12V/24V DC-DC modules delivering up to 1.5A continuous output. IC Role / Device Role / Timing Role: Standard rectifier conducting during transformer secondary positive half-cycle; blocks reverse voltage during reset phase. Use Value: 600V VRRM provides 2× safety margin over 24V output reflected spikes; 1.05V VF limits power loss to <1.6W at full load. | Use Scenario: Freewheeling path in 48V motor drive inverters with IGBT-based H-bridge topology. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path during IGBT turn-off; clamps inductive kickback. Use Value: 50A IFSM absorbs energy from 100 µH inductors with 1A steady-state current; 175°C TJ rating sustains operation near heatsink baseplate. |
| AC-DC Adapter Input Bridge Leg | Industrial Sensor Power Supply Rectification |
Use Scenario: Single-diode leg in compact 5W–10W AC-DC adapters using half-wave or voltage-doubler configuration. IC Role / Device Role / Timing Role: Conducts during positive AC half-cycle; blocks reverse voltage up to 600V peak line-to-line surges. Use Value: SOD-123W footprint saves >30% board area vs. DO-214AC; moisture level 1 eliminates pre-bake in high-volume SMT lines. | Use Scenario: Primary rectification in 24V industrial sensor nodes powered from 24VAC control rails. IC Role / Device Role / Timing Role: Converts 24VAC (34V peak) to unregulated DC; operates continuously at ambient up to 85°C. Use Value: 100 µA IR max at 125°C ensures <2.5 µW reverse power dissipation-critical for ultra-low-power sensor sleep modes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L60S | 1.5A, 600V, TO-277A package (RθJA ≈ 110°C/W); VF = 1.15V max @ 1.5A | Higher thermal resistance requires larger copper area; less suitable for space-constrained layouts | Prefer when higher surge rating (60A) or alternate mounting (stud) is needed |
| ES1J | 1A, 600V, DO-214AA package; VF = 1.7V max @ 1A; IFSM = 30A | Lower current rating and higher VF increase conduction loss by ~40% at 1.5A equivalent load | Select only if legacy DO-214AA footprint must be retained and derated to 1A continuous |
Compared with STTH1L60S and ES1J, the S15JLW delivers superior thermal performance in minimal area (SOD-123W), lower VF for reduced losses, and moisture level 1 compatibility-making it optimal for high-density, high-reliability SMT power conversion designs.

FAQ
What is the maximum repetitive peak reverse voltage (VRRM) of the S15JLW?
The S15JLW has a VRRM rating of 600 V, as specified in the absolute maximum ratings table. This value is fixed for the S15JLW variant within the S15xLW series and is validated per JEDEC test conditions. The S15JLW must not be subjected to reverse voltages exceeding this limit under normal operation to ensure long-term reliability and prevent avalanche breakdown.
Does the S15JLW have moisture sensitivity level (MSL) certification, and what does it mean for assembly?
Yes, the S15JLW is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life at ≤30°C/60% RH and requires no baking prior to reflow soldering. This simplifies SMT line logistics and eliminates moisture-related popcorning risk-critical for high-yield automated placement in consumer and industrial power modules using the S15JLW.
What is the forward voltage (VF) of the S15JLW at 1.5A and 125°C junction temperature?
At 1.5A forward current and 125°C junction temperature, the S15JLW exhibits a maximum forward voltage of 1.05 V, with a typical value of 0.87 V. This data is measured under pulsed conditions (PW = 0.3 ms) and is essential for calculating conduction losses and thermal rise in high-temperature operating environments where the S15JLW is deployed.
Can the S15JLW be used as a direct replacement for the S15DLW or S15MLW in an existing design?
No-the S15JLW is not a direct replacement for S15DLW (200V) or S15MLW (1000V) due to differing VRRM ratings. While all share identical SOD-123W package, pinout, and thermal specs, substituting S15JLW into a design validated for 200V or 1000V may cause overvoltage failure or unnecessary derating. Always verify reverse voltage stress margins before interchanging any S15xLW variant, including the S15JLW.
What is the junction-to-ambient thermal resistance (RθJA) of the S15JLW, and how is it measured?
The S15JLW has an RθJA of 85°C/W, measured on a standardized 5 mm × 5 mm copper pad PCB per JEDEC JESD51-3. This value assumes natural convection and defines the thermal bottleneck when board-level copper area is limited. Designers use this parameter to estimate junction temperature rise (ΔTJ = Pd × RθJA) and validate safe operation of the S15JLW under actual power dissipation conditions.
