Product details
Overview
S3M M6G from Taiwan Semiconductor is a 3A, 1000V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring 1.15V max forward voltage at 3A, 100A non-repetitive surge current, and 150°C maximum junction temperature-used in high-voltage AC/DC front-end stages of industrial SMPS and lighting converters.
For engineers reviewing the S3M M6G datasheet, S3M M6G pinout, S3M M6G application, or S3M M6G equivalent, key selection criteria include peak reverse voltage rating, thermal resistance (RθJL = 13°C/W), surge robustness (IFSM = 100A), and RoHS/halogen-free compliance for high-reliability power conversion designs.
Technical Context
This device is a single-die, standard recovery rectifier optimized for line-frequency and low-frequency switching applications. Its 1500ns reverse recovery time (trr) and 60pF junction capacitance reflect trade-offs favoring low conduction loss over fast switching speed.
Designed for surface-mount assembly with matte tin-plated leads (J-STD-002 compliant) and moisture sensitivity level 1 (J-STD-020), the S3M M6G supports automated placement and reflow without preconditioning, while its UL 94V-0 molded compound ensures flame-retardant reliability in enclosed power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 1000 V - Withstands up to 1000V repetitive reverse voltage, enabling use in 800V DC bus or 600V AC input rectification |
| IF | 3 A continuous - Rated average forward current at TL = 75°C, defining steady-state power handling capability |
| IFSM | 100 A (8.3ms) - Supports high-energy inrush and fault transients without failure in offline SMPS input stages |
| VF | ≤1.15 V @ 3A, 25°C - Low conduction loss improves efficiency and reduces heatsink requirements in 3A-class supplies |
| RθJL | 13 °C/W - Enables direct thermal path from junction to lead, critical for PCB copper pour design in high-power density layouts |
| trr | 1500 ns - Standard recovery behavior suitable for 50/60Hz and <100kHz operation; not intended for high-frequency synchronous rectification |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EWH10-M3/45 | Same 1000V VRRM, 3A IF, but TO-277A package (smaller footprint, higher RθJA) | Lower profile and reduced board area; less thermal mass limits surge handling in high-peak-current designs | Preferred where space is constrained and surge duty is moderate |
| ON Semiconductor MUR3100CT | 1000V, dual common-cathode configuration; faster trr (75ns) but higher VF (1.7V) | Enables center-tap or dual-output topologies; unsuitable for single-diode replacement due to pinout and internal structure | Select only when dual-diode functionality or ultra-fast recovery is required |
Compared with VS-3EWH10-M3/45 and MUR3100CT, the S3M M6G offers superior surge robustness and lower forward drop in a proven DO-214AB platform, making it optimal for cost-sensitive, thermally demanding, single-diode rectification where standard recovery timing is acceptable.

FAQ
What is the maximum junction temperature rating for the S3M M6G?
The S3M M6G has a maximum junction temperature (TJMAX) of +150°C, verified per absolute maximum ratings table. This rating allows operation in high-ambient environments such as enclosed LED drivers or industrial enclosures, provided thermal design maintains junction temperature below this limit using PCB copper pour or minimal heatsinking. The S3M M6G's RθJL = 13°C/W supports effective heat transfer to the PCB lead frame.
Is the S3M M6G RoHS and halogen-free compliant?
Yes, the S3M M6G is fully RoHS compliant and halogen-free, as confirmed in the official Taiwan Semiconductor product documentation. This compliance meets EU Directive 2011/65/EU and IPC-1752A material declarations, enabling use in export-controlled and environmentally regulated end equipment without exemption requests. The S3M M6G uses green molding compound and matte tin-plated leads.
What does the "M6G" suffix indicate in S3M M6G?
The "M6G" suffix in S3M M6G is Taiwan Semiconductor's internal date and factory code: "M" denotes manufacturing year (2023), "6" indicates calendar week (week 6), and "G" identifies the fabrication site. It is not an electrical variant identifier-the electrical specifications are fully defined by the base part number S3M, which specifies 1000V VRRM and 3A IF.
Can the S3M M6G replace the S3K or S3J in an existing design?
No, the S3M M6G is not a direct replacement for S3K (800V) or S3J (600V) without circuit review. While all share identical DO-214AB packaging and thermal characteristics, the S3M M6G's 1000V VRRM may alter voltage derating margins and snubber design. Its higher blocking voltage does not guarantee improved surge immunity beyond rated IFSM, and layout changes may be needed if voltage clearance was optimized for lower-rated variants.
What is the reverse recovery time (trr) of the S3M M6G and how does it affect circuit performance?
The S3M M6G has a typical reverse recovery time (trr) of 1500 ns under IF = 0.5A, IR = 1.0A, Irr = 0.25A test conditions. This standard recovery behavior generates measurable switching loss and EMI in circuits operating above ~50kHz. For S3M M6G applications, designers should avoid high-frequency PWM topologies and instead target line-frequency or low-kHz rectification where trr impact is negligible.
