Product details
Overview
S8KC M6G from Taiwan Semiconductor is an 8A, 800V surface-mount silicon rectifier diode in DO-214AB (SMC) package, featuring glass-passivated junction, low forward voltage drop (≤0.985 V at 8 A), high surge capability (200 A @ 8.3 ms), and RoHS/halogen-free compliance. It serves as primary AC/DC input rectifier in compact power supplies.
For engineers reviewing the S8KC M6G datasheet, S8KC M6G pinout, S8KC M6G application, or S8KC M6G equivalent, key selection criteria include repetitive peak reverse voltage (800 V), thermal resistance (RθJL = 12.5 °C/W), moisture sensitivity level (MSL 1), cathode-band polarity marking, and tape-and-reel packaging (3,000 pcs).
Technical Context
The S8KC M6G is a single-die, standard recovery rectifier optimized for switching-mode power conversion. Its 800 V VRRM, 200 A IFSM (8.3 ms), and 12.5 °C/W junction-to-lead thermal resistance enable robust operation under transient overload and sustained conduction in high-density layouts.
Electrical behavior is characterized by ≤0.985 V forward voltage at 8 A/25°C, ≤10 µA reverse leakage at rated VR/25°C, and 48 pF junction capacitance at 1 MHz/4 V - parameters critical for EMI control and efficiency in 50–100 kHz SMPS designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 800 V - supports 560 V RMS input with 1.4× safety margin in universal-input SMPS |
| IF | 8 A continuous average forward current - defines maximum steady-state conduction capability |
| IFSM (8.3 ms) | 200 A - withstands inrush surges during cold-start without degradation |
| VF @ 8 A | ≤0.985 V - limits conduction loss to ≤7.9 W per device at full load |
| RθJL | 12.5 °C/W - enables direct PCB copper pour heatsinking without external heatsink |
| MSL Level | Level 1 (per J-STD-020) - allows unlimited floor life and standard reflow without baking |
Pinout & Package
Package: DO-214AB (SMC), molded plastic case meeting UL 94V-0; matte tin-plated leads; cathode indicated by band; weight ≈ 0.270 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | AC input connection point | Accepts incoming AC waveform; connects to transformer secondary or bridge input |
| Cathode | DC output connection point | Delivers rectified positive DC; ties to bulk capacitor or PFC stage input |
Key Features
| Feature | Design Value |
|---|---|
| Glass-passivated junction | Enhances long-term reliability under humidity and thermal cycling stress |
| Low VF (≤0.985 V) | Reduces conduction losses and improves system efficiency at 8 A load |
| High IFSM (200 A) | Eliminates need for parallel devices in surge-prone adapter applications |

Applications
| Switching Mode Power Supply (SMPS) | AC-DC Adapters |
|---|---|
Use Scenario: Primary-side rectification in offline flyback or forward converters with universal AC input (85–265 VAC). IC Role / Device Role / Timing Role: Standard recovery rectifier converting AC line to unregulated DC bus. Use Value: 800 V rating ensures safe operation at 1.4× peak line voltage (375 V) with margin; 12.5 °C/W RθJL supports thermally constrained board layouts. | Use Scenario: Input rectification in compact wall-mounted adapters for consumer electronics. IC Role / Device Role / Timing Role: High-current discrete rectifier replacing legacy axial DO-41 or radial DO-15 parts. Use Value: DO-214AB footprint enables automated placement and higher power density than through-hole alternatives; MSL 1 eliminates baking step. |

Use Scenario: Bulk rectification in constant-current LED drivers for commercial lighting. IC Role / Device Role / Timing Role: Input-stage rectifier feeding buck or buck-boost controller ICs. Use Value: Low VF minimizes heat generation in enclosed fixtures; halogen-free construction meets IEC 61249-2-21 requirements. | Use Scenario: Intermediate bus rectification in isolated DC-DC modules (e.g., 48 V input → 12 V output). IC Role / Device Role / Timing Role: Secondary-side rectifier handling high average current in synchronous or non-synchronous topologies. Use Value: 200 A surge rating accommodates startup transients; 48 pF CJ limits high-frequency noise coupling into control circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STTH8R06D (STMicroelectronics) | 600 V VRRM, 8 A, TO-220AC package, faster recovery (trr = 65 ns) | Requires heatsink; unsuitable for 800 V designs; better for high-frequency PFC stages | Select only if lower VRRM suffices and through-hole mounting is acceptable |
| VS-8EWH06FN-M3 (Vishay) | 600 V VRRM, 8 A, DO-214AB, 0.92 V VF, MSL 1 | Lower voltage rating; identical footprint but insufficient for 800 V systems | Valid drop-in replacement only in 600 V-rated designs; verify system derating |
Compared with STTH8R06D and VS-8EWH06FN-M3, the S8KC M6G uniquely delivers 800 V standoff in a surface-mount MSL 1 package - enabling compact, high-reliability rectification where voltage margin and automated assembly are mandatory.

FAQ
What is the peak repetitive reverse voltage rating of the S8KC M6G?
The S8KC M6G has a peak repetitive reverse voltage (VRRM) rating of 800 V. This value is confirmed in the Absolute Maximum Ratings table on page 1 of the official Taiwan Semiconductor datasheet (Version G2210). It defines the maximum reverse voltage the device can block repeatedly without breakdown, making it suitable for universal-input SMPS designs where peak line voltage reaches ~375 V.
Does the S8KC M6G have a defined moisture sensitivity level (MSL)?
Yes, the S8KC M6G is rated MSL Level 1 per J-STD-020. This is explicitly stated in the FEATURES section of the datasheet. MSL Level 1 means the device has unlimited floor life and may be placed directly onto PCBs using standard reflow profiles without prior baking - a critical advantage for high-throughput SMT lines.
What is the forward voltage drop of the S8KC M6G at its rated current?
The S8KC M6G exhibits a maximum forward voltage drop (VF) of 0.985 V at 8 A and 25°C junction temperature, as specified in the Electrical Specifications table. This value is measured under pulsed conditions (PW = 0.3 ms) and directly impacts conduction loss - resulting in ≤7.9 W dissipation at full rated current.
Is the S8KC M6G RoHS and halogen-free compliant?
Yes, the S8KC M6G is both RoHS compliant and halogen-free per IEC 61249-2-21. These compliance statements appear in the FEATURES section of the official datasheet. The halogen-free designation confirms absence of bromine, chlorine, and related flame-retardant compounds in the molding compound.
What package type does the S8KC M6G use, and what are its key mechanical attributes?
The S8KC M6G uses the DO-214AB (SMC) surface-mount package. Key mechanical attributes include UL 94V-0 flammability rating, matte tin-plated solderable leads (per J-STD-002), cathode polarity indicated by a band, and approximate weight of 0.270 g. Dimensions and pad layout recommendations are provided in the Package Outline Dimensions section of the datasheet.
