Product details
Overview
S1MLS RVG from Taiwan Semiconductor is a 1.2A, 1000V standard surface-mount silicon rectifier diode in SOD-123HE package, designed for high-efficiency DC/DC conversion and switching-mode power supplies. It delivers 1.3V max forward voltage at 1.2A, 50A peak surge current capability, and operates up to 175°C junction temperature.
For engineers reviewing the S1MLS RVG datasheet, S1MLS RVG pinout, S1MLS RVG application, or S1MLS RVG equivalent, key selection criteria include repetitive peak reverse voltage (1000V), thermal resistance (RθJA = 86°C/W), moisture sensitivity level (MSL 1), and RoHS/halogen-free compliance for industrial and automotive-grade power designs.
Technical Context
The S1MLS RVG is a single-die, unidirectional standard rectifier optimized for high-voltage, medium-current switching applications. Its 1000V VRRM rating supports input stages in offline SMPS and PFC front-ends, while its 50A IFSM withstands transient surges common in inductive load switching.
Thermal performance is defined with reference to a 5mm × 5mm copper pad PCB layout: RθJL = 46°C/W enables efficient heat transfer to the PCB lead, and RθJC = 50°C/W confirms low internal junction-to-case resistance-critical for sustained 1.2A average forward conduction under elevated ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Supports direct rectification of 700 VRMS AC inputs (e.g., 480 VAC three-phase lines) |
| IF | 1.2 A - Rated continuous forward current at TA = 25°C on standard test board |
| IFSM | 50 A - Withstands 8.3 ms half-sine surge without degradation; suitable for inrush-limited converters |
| VF (max) | 1.3 V @ IF = 1.2 A, TJ = 25°C - Limits conduction loss to ≤1.56 W per device in steady-state operation |
| TJ max | 175 °C - Enables operation in sealed enclosures or high-ambient environments without derating below 100°C ambient |
| RθJA | 86 °C/W - Requires ≥5 mm × 5 mm Cu pad for thermal compliance at full rated current |
| MSL | Level 1 (per J-STD-020) - No floor life limitation; compatible with standard reflow profiles without baking |
Pinout & Package
Package: SOD-123HE - Surface-mount plastic case with matte tin-plated leads, UL 94V-0 molding compound, cathode band polarity marking, and 0.022 g typical weight.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., transformer secondary center-tap or switch node return) |
| Cathode | Forward current exit / reverse-blocking terminal | Marked by visible band; ties to output rail or filter capacitor positive; blocks 1000 V reverse bias |
Key Features
| Feature | Design Value |
|---|---|
| High surge current capability | 50 A IFSM enables robustness against line transients and motor-start currents without external snubbing |
| Low forward voltage | 1.3 V max at 1.2 A reduces conduction loss by ~15% vs. comparable 1A/1000V diodes, improving system efficiency |
| Moisture sensitivity level 1 | No bake requirement before SMT assembly; eliminates process step and avoids potential die damage from moisture-induced popcorning |
| Halogen-free construction | Complies with IEC 61249-2-21; meets environmental requirements for industrial and transportation electronics |
| Compact SOD-123HE footprint | 0.022 g mass and JEDEC-standardized outline enable high-density layouts in space-constrained DC/DC modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar standard rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1L06S | 1 A, 600 V, TO-277 package; higher VF (1.7 V typ), lower IFSM (30 A) | Limited to ≤600 V systems; requires larger footprint and higher thermal budget | Select only if 600 V rating suffices and TO-277 mounting is preferred |
| ES1J-M3/84A | 1 A, 600 V, SOD-123HE; same package but lower VRRM and IF | Not suitable for 1000 V applications; acceptable only in legacy 400–600 V designs | Use only when voltage derating allows and cost is primary constraint |
Compared with STTH1L06S and ES1J-M3/84A, the S1MLS RVG uniquely combines 1000 V rating, 1.2 A current, and SOD-123HE packaging-enabling compact, high-voltage rectification without trade-offs in surge capability or thermal compliance.

FAQ
What is the maximum repetitive peak reverse voltage rating for S1MLS RVG?
The S1MLS RVG has a maximum repetitive peak reverse voltage (VRRM) of 1000 V. This rating is confirmed in the Absolute Maximum Ratings table and applies across the full operating temperature range. It ensures reliable blocking of high-voltage transients in offline power supplies and industrial rectification circuits where S1MLS RVG is deployed.
Is S1MLS RVG suitable for reflow soldering without pre-baking?
Yes, S1MLS RVG is rated MSL Level 1 per J-STD-020, meaning it has unlimited floor life and does not require baking prior to reflow soldering. This simplifies manufacturing flow and eliminates moisture-related risks such as popcorning during SMT assembly-making S1MLS RVG ideal for high-volume automated placement processes.
What is the forward voltage drop of S1MLS RVG at rated current?
The S1MLS RVG exhibits a maximum forward voltage (VF) of 1.3 V at IF = 1.2 A and TJ = 25°C, measured under pulsed conditions (PW = 0.3 ms). This value directly determines conduction losses in the application; for example, at full rated current, S1MLS RVG dissipates ≤1.56 W, supporting thermally constrained PCB layouts.
Does S1MLS RVG comply with halogen-free and RoHS requirements?
Yes, S1MLS RVG is both RoHS compliant and halogen-free per IEC 61249-2-21. These certifications are explicitly stated in the FEATURES section of the official datasheet and verified through material declarations. Designers specifying S1MLS RVG for environmentally regulated markets-including EU industrial equipment and automotive subsystems-can rely on full compliance documentation.
What thermal resistance values apply to S1MLS RVG in standard mounting?
S1MLS RVG specifies RθJA = 86°C/W, RθJL = 46°C/W, and RθJC = 50°C/W-all measured on a 5 mm × 5 mm copper pad PCB per JEDEC standards. These values define thermal design boundaries: for example, maintaining TJ ≤ 175°C at 1.2 A requires limiting ambient temperature to ≤89°C when using the standard footprint, confirming S1MLS RVG's suitability for high-temperature deployments.
