Product details
Overview
S12KC M6G from Taiwan Semiconductor is a 12A, 800V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, 1.1V max forward voltage at 12A/25°C, 300A peak surge capability, and 150°C maximum junction temperature-used in high-efficiency AC/DC converters and industrial SMPS front-ends.
For engineers reviewing the S12KC M6G datasheet, S12KC M6G pinout, S12KC M6G application, or S12KC M6G equivalent, key selection criteria include repetitive peak reverse voltage (800V), thermal resistance (9°C/W junction-to-lead), moisture sensitivity level (J-STD-020 Level 1), and RoHS/halogen-free compliance for automated SMT assembly in power supply designs.
Technical Context
The S12KC M6G is a single-die, standard recovery rectifier optimized for switching-mode power conversion. Its glass-passivated junction ensures stable reverse leakage (<1 µA at 25°C, <250 µA at 125°C) and robust surge tolerance (300A IFSM, 8.3ms half-sine).
Thermal performance is defined by RθJL = 9°C/W and RθJA = 44°C/W, enabling reliable operation up to 150°C junction temperature. The DO-214AB (SMC) package supports high-current handling with matte tin-plated leads compliant with J-STD-002 solderability and JESD 201 Class 2 whisker resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - Maximum repetitive reverse blocking voltage; defines safe operating range in bridge or output rectification stages |
| IF | 12 A - Continuous average forward current; determines heatsink sizing and conduction loss in 60 Hz–100 kHz SMPS |
| IFSM | 300 A - Non-repetitive surge rating; enables survival during cold-start inrush or line transients |
| VF (max) | 1.1 V @ 12A, 25°C - Forward voltage drop directly impacts conduction loss and thermal design at full load |
| RθJL | 9 °C/W - Junction-to-lead thermal resistance; critical for estimating die temperature rise under PCB copper pad cooling |
| CJ | 78 pF @ 1 MHz, 4V - Junction capacitance affects high-frequency switching noise and EMI filter design |
Pinout & Package
DO-214AB (SMC) surface-mount package with cathode-indicated band; two-terminal device (anode and cathode) mounted on PCB via gull-wing leads. Matte tin-plated terminals meet J-STD-002 solderability and JESD 201 Class 2 whisker requirements.

Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH1208D | 12A, 800V, TO-220AC package; VF = 1.7V (typ) at 12A; RθJA = 30°C/W (with heatsink) | Requires through-hole mounting and external heatsink; higher VF increases conduction loss | Preferred where thermal budget allows discrete heatsinking and board space permits larger footprint |
| VS-12EWH08-M3 | 12A, 800V, DO-214AB; VF = 1.15V (max) at 12A; MSL Level 1; same package outline | Identical SMC footprint and moisture handling; slightly higher VF spec but same thermal metrics | Drop-in replacement for S12KC M6G in existing SMT layouts with verified solder profile compatibility |
Compared with STTH1208D, S12KC M6G offers superior SMT integration and lower VF; versus VS-12EWH08-M3, it delivers tighter VF consistency and identical thermal resistance-making it optimal for high-density, thermally constrained power supply designs.

FAQ
What is the maximum junction temperature rating for the S12KC M6G?
The S12KC M6G has a maximum junction temperature (TJ) rating of +150°C, validated across its full operating range from –55°C to +150°C. This specification enables use in thermally demanding environments such as enclosed industrial power supplies and outdoor LED drivers. Derating curves in the official TSC datasheet (Version D2102) define allowable IF vs. ambient temperature, and the 9°C/W RθJL value supports accurate thermal modeling when mounted on standard 1-oz copper pads.
Does the S12KC M6G have a specified moisture sensitivity level (MSL)?
Yes, the S12KC M6G 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 is confirmed in the "Mechanical Data" section of the TSC datasheet (Version D2102) and aligns with its matte tin-plated leads and UL 94V-0 molding compound-critical for high-yield, high-throughput SMT assembly lines.
What is the forward voltage drop of the S12KC M6G under typical operating conditions?
The S12KC M6G exhibits a maximum forward voltage (VF) of 1.1 V at IF = 12 A and TJ = 25°C, measured under pulse conditions (PW = 0.3 ms). At elevated temperatures (e.g., TJ = 125°C), VF decreases slightly due to semiconductor physics, but the 1.1 V max remains the design-critical value for worst-case conduction loss calculation in power supply thermal analysis.
Is the S12KC M6G RoHS and halogen-free compliant?
Yes, the S12KC M6G meets both EU RoHS Directive 2011/65/EU and IEC 61249-2-21 halogen-free requirements. This compliance is explicitly stated in the "Features" section of the TSC datasheet (Version D2102) and verified through material declarations-ensuring suitability for environmentally regulated markets including Europe, Japan, and North America.
What package type does the S12KC M6G use, and what are its key mechanical attributes?
The S12KC M6G uses the DO-214AB (SMC) surface-mount package, with dimensions per JEDEC outline. Key mechanical attributes include UL 94V-0 flammability-rated epoxy molding, matte tin-plated gull-wing leads compliant with J-STD-002, cathode polarity indicated by a visible band, and a nominal weight of 0.270 g. These features support automated pick-and-place, lead-free reflow, and IPC-A-610 Class 2/3 assembly standards.
