Product details
Overview
SK810C M6G from Taiwan Semiconductor is an 8A, 100V Schottky barrier rectifier in DO-214AB (SMC) package, designed for high-efficiency DC/DC conversion in switching mode power supplies. It features 0.90V forward voltage at 8A/25°C, 150A non-repetitive surge capability, and 10,000 V/µs dV/dt rating, enabling robust operation in compact AC-DC adapters and LED drivers.
For engineers reviewing the SK810C M6G datasheet, SK810C M6G pinout, SK810C M6G application, or SK810C M6G equivalent, key selection criteria include its 100V VRRM rating, thermal resistance of 20°C/W, junction temperature range up to +150°C, and moisture sensitivity level 1 compliance - all critical for high-density, thermally constrained industrial power designs.
Technical Context
The SK810C M6G implements a single-die Schottky structure optimized for low conduction loss at 8A continuous forward current. Its 100V reverse blocking capability targets mid-voltage SMPS outputs where higher VRRM than SK86C (60V) is required without stepping up to ultra-high-voltage diodes.
Thermal performance is defined by RθJA = 20°C/W and TJ(max) = +150°C, supporting operation under sustained load in enclosed environments. The device's 10,000 V/µs dV/dt rating ensures immunity to fast transient voltage spikes common in flyback and LLC resonant converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - supports output rectification in 48V–60V bus systems with safety margin |
| IF(AV) | 8 A - delivers continuous DC output current in 100W–150W SMPS designs |
| VF @ 8A, 25°C | 0.90 V - reduces conduction loss to ~7.2W per device, improving system efficiency |
| IFSM (8.3ms) | 150 A - withstands inrush surges during cold-start of high-capacitance output stages |
| TJ(max) | +150 °C - enables reliable operation in sealed enclosures with limited airflow |
| RθJA | 20 °C/W - requires ≥1.5 cm² copper pour on PCB for thermal management at full load |
| dV/dt | 10,000 V/µs - suppresses false turn-on in high-frequency, high-dV/dt converter topologies |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-8EWH10FN-M3/45 | Same DO-214AB package, 8A/100V, VF = 0.82V @ 8A (lower conduction loss) | Slightly lower thermal resistance (18°C/W), tighter VF distribution | Preferred where peak efficiency >92% is mandatory; requires validation of Vishay's moisture sensitivity handling |
| ON Semiconductor SB8100E | DO-214AB, 8A/100V, VF = 0.95V @ 8A (higher conduction loss), TJ(max) = +150°C | Higher IR leakage at 100°C (25mA vs. SK810C's 10mA), wider VF tolerance | Suitable for cost-sensitive, non-thermally constrained applications; verify layout compatibility due to minor die size variation |
Compared with VS-8EWH10FN-M3/45 and SB8100E, the SK810C M6G offers balanced trade-offs: lower VF than SB8100E for better efficiency, and superior high-temperature IR performance versus both alternatives - making it optimal for thermally dense, long-life industrial power supplies.

FAQ
What is the maximum junction temperature rating for the SK810C M6G?
The SK810C M6G has a maximum junction temperature (TJ(max)) of +150°C, verified per absolute maximum ratings table in the official TSC datasheet revision L2102. This allows the SK810C M6G to operate reliably in sealed or high-ambient-temperature environments typical of industrial power supplies and LED drivers without derating at full 8A current until case temperature exceeds ~105°C.
Does the SK810C M6G have a guard ring structure, and what is its function?
Yes, the SK810C M6G incorporates a guard ring structure explicitly stated in the TSC datasheet features list. This design mitigates electric field crowding at the silicon periphery, preventing premature avalanche breakdown under 100V reverse bias. As a result, the SK810C M6G maintains stable VRRM performance and extended lifetime in high-stress applications like flyback converters with poor snubbing.
What is the forward voltage of the SK810C M6G at 8A and 25°C?
The forward voltage (VF) of the SK810C M6G is 0.90 V at 8A and 25°C, as specified in the Electrical Specifications table of the TSC datasheet. This value is measured under pulsed conditions (PW = 0.3ms) and represents the typical conduction loss per device - a key parameter used to calculate power dissipation and thermal design margins for the SK810C M6G in final applications.
Is the SK810C M6G compliant with RoHS and halogen-free standards?
Yes, the SK810C M6G is RoHS compliant and halogen-free per IEC 61249-2-21, as confirmed in the Features section of the official TSC datasheet. These certifications apply to the entire device - including molding compound, lead finish, and internal die - ensuring the SK810C M6G meets environmental requirements for export to EU, China, and other regulated markets.
What is the moisture sensitivity level (MSL) of the SK810C M6G, and does it require baking before reflow?
The SK810C M6G has a moisture sensitivity level (MSL) of Level 1 per J-STD-020, meaning it is not humidity-sensitive and may be stored indefinitely at ambient conditions without dry packing. Therefore, no baking is required prior to reflow soldering - a direct benefit confirmed in the Features list and simplifying manufacturing for the SK810C M6G in high-volume SMT lines.
