Product details
Overview
S1DLW RVG from Taiwan Semiconductor is a 1 A, 200 V standard surface-mount silicon rectifier diode in SOD-123W package, featuring 30 A peak surge current capability, 1.1 V max forward voltage at 1 A, and 1 µA max reverse leakage at 25°C - deployed in DC-DC converters and switching-mode power supplies.
For engineers reviewing the S1DLW RVG datasheet, S1DLW RVG pinout, S1DLW RVG application, or S1DLW RVG equivalent, key selection criteria include repetitive peak reverse voltage (200 V), thermal resistance (RθJL = 25 °C/W), junction temperature range (–55 to +175 °C), and RoHS/halogen-free compliance for industrial power conversion designs.
Technical Context
The S1DLW RVG is a single-die, unidirectional silicon PN junction rectifier optimized for high-efficiency, low-loss operation in medium-voltage switching power supplies. Its SOD-123W package supports automated placement and delivers 30 A non-repetitive surge current handling with 1.1 V forward voltage drop at rated 1 A DC current.
Thermal performance is defined by RθJL = 25 °C/W and RθJA = 80 °C/W, enabling reliable operation up to +175 °C junction temperature. Reverse leakage remains ≤1 µA at 25°C and ≤50 µA at 125°C under rated 200 V reverse bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF (Rated Forward Current) | 1 A continuous DC current - defines maximum steady-state conduction capability without derating |
| VRRM (Repetitive Peak Reverse Voltage) | 200 V - maximum allowable reverse voltage before breakdown; sets operating margin in 24–48 V input DC-DC stages |
| IFSM (Peak Forward Surge Current) | 30 A (8.3 ms half-sine) - withstands inrush and transient overloads in SMPS startup and fault conditions |
| VF (Max Forward Voltage) | 1.1 V @ 1 A, 25°C - directly determines conduction loss (1.1 W per diode at full load) |
| IR (Max Reverse Leakage) | 1 µA @ 200 V, 25°C - ensures minimal standby power loss in high-impedance bias networks |
| RθJL (Junction-to-Lead Thermal Resistance) | 25 °C/W - enables efficient heat transfer to PCB copper, critical for compact layout in space-constrained converters |
| Junction Temperature Range | –55°C to +175°C - supports operation in automotive under-hood and industrial ambient environments |
Pinout & Package
Package: SOD-123W - surface-mount, molded plastic case with matte tin-plated leads, UL 94V-0 rated, polarity indicated by cathode band, weight ≈ 0.019 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side of circuit (e.g., switch node or ground return); must be routed with adequate copper area for thermal dissipation |
| Cathode | Forward current exit / reverse blocking terminal | Connected to higher-potential rail (e.g., output capacitor positive); cathode band marking enables automated optical inspection and orientation verification |
Key Features
| Feature | Design Value |

| RoHS & Halogen-Free Compliance | Meets EU RoHS Directive 2011/65/EU and IEC 61249-2-21 - required for export to EU, China, and Korea markets |
| High Surge Current Capability | 30 A IFSM - sustains repeated inrush events in AC-DC front-ends and flyback transformer reset paths |
| Low Forward Voltage Drop | 1.1 V max at 1 A - reduces conduction losses by ~15% vs. legacy 1N400x series in same footprint |
| Compact SOD-123W Footprint | 2.7 × 1.6 × 1.1 mm - enables high-density layout in portable and IoT power modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor MUR120RLG | 200 V VRRM, 1 A IF, but TO-220AC package (larger, through-hole); VF = 1.0 V typ, IFSM = 35 A | Requires PCB redesign for through-hole mounting; better surge handling but higher thermal mass limits switching speed | Select when board-level mechanical robustness or legacy through-hole assembly is required |
| Vishay VS-1EWH02-M3/5AT | 200 V VRRM, 1 A IF, SOD-123W package; VF = 1.15 V max, IR = 5 µA max at 25°C | Near-identical footprint and mounting; slightly higher leakage affects ultra-low-power standby circuits | Preferred for drop-in replacement where tighter IR spec is not critical |
Compared with MUR120RLG and VS-1EWH02-M3/5AT, the S1DLW RVG offers optimal balance of SMD manufacturability, thermal efficiency (RθJL = 25 °C/W), and low-leakage performance - making it ideal for high-volume, space-constrained DC-DC modules requiring MSL Level 1 compatibility.

FAQ
What is the maximum junction temperature rating for the S1DLW RVG?
The S1DLW RVG has a maximum junction temperature (TJ) rating of +175°C, with a minimum of –55°C. This wide operating range allows deployment in demanding environments such as industrial control cabinets and automotive under-hood power modules. The S1DLW RVG maintains stable electrical characteristics across this full range, supported by its 25 °C/W junction-to-lead thermal resistance.
Is the S1DLW RVG RoHS and halogen-free compliant?
Yes, the S1DLW RVG is fully RoHS compliant per EU Directive 2011/65/EU and halogen-free in accordance with IEC 61249-2-21. These certifications are verified in TSC's official product documentation and confirmed on distributor packaging labels. The S1DLW RVG meets environmental requirements for export to regulated markets including the EU, South Korea, and China.
What does the 'RVG' suffix indicate in S1DLW RVG?
The 'RVG' suffix in S1DLW RVG denotes Taiwan Semiconductor's tape-and-reel packaging option: 10,000 units per reel, compatible with standard SMT pick-and-place equipment. It does not affect electrical specifications - all key parameters (VRRM = 200 V, IF = 1 A, VF ≤ 1.1 V) remain identical to the base S1DLW part. The S1DLW RVG is functionally and dimensionally equivalent to S1DLW in SOD-123W.
Can the S1DLW RVG replace older 1N400x series diodes in existing designs?
The S1DLW RVG can replace 1N4001–1N4007 in many SMD-adapted layouts, but only if the PCB pad design matches SOD-123W (2.7 × 1.6 mm). Unlike through-hole 1N400x, the S1DLW RVG offers superior thermal performance (RθJL = 25 °C/W vs. ~50 °C/W for DO-41), lower VF, and MSL Level 1 handling. The S1DLW RVG is not a direct pin-compatible substitute without footprint revision.
What is the reverse leakage current specification for the S1DLW RVG at elevated temperature?
At 125°C and rated 200 V reverse voltage, the S1DLW RVG exhibits a maximum reverse leakage current (IR) of 50 µA, per TSC datasheet Version D2109. This value is measured under 30 ms pulse conditions and reflects stable behavior under thermal stress. At 25°C, IR is limited to 1 µA max - critical for low-power standby circuits where quiescent loss must be minimized. The S1DLW RVG's leakage profile is fully characterized across its operational temperature range.
