Product details
Overview
SK86C M6G from Taiwan Semiconductor is an 8A, 60V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, featuring low forward voltage (0.75 V @ 8 A, 25°C), 150 A surge capability, and junction temperature up to +150°C. It serves as a high-efficiency output rectifier in DC-DC converters and offline SMPS.
For engineers reviewing the SK86C M6G datasheet, SK86C M6G pinout, SK86C M6G application, or SK86C M6G equivalent, key selection criteria include reverse voltage rating (60 V), thermal resistance (20 °C/W), moisture sensitivity level (J-STD-020 Level 1), RoHS/halogen-free compliance, and cathode-band polarity marking.
Technical Context
The SK86C M6G is a single-die Schottky rectifier optimized for high-frequency switching applications. Its 60 V repetitive peak reverse voltage (VRRM) and 42 V RMS reverse voltage support mid-voltage secondary-side rectification in flyback and forward converters.
With a typical forward voltage of 0.75 V at 8 A and 25°C, it delivers lower conduction loss than standard PN diodes. Its 10,000 V/µs dV/dt rating ensures robustness against fast transient voltage spikes in compact power stages.

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-8EWH06FN-M3 | Same 60 V VRRM, 8 A IF, but TO-277A package (lower RθJA = 15 °C/W); VF = 0.72 V | Requires different pad layout; better thermal performance but larger footprint | Preferred when board space permits and thermal headroom is critical |
| ON Semiconductor SB860-E3/54 | 60 V VRRM, 8 A IF, DO-214AB package; VF = 0.74 V; IR = 12 mA @ 100°C | Near-identical form factor and electrical specs; slightly higher leakage at high temp | Suitable drop-in alternative where Taiwan Semiconductor supply is constrained |
Compared with VS-8EWH06FN-M3 and SB860-E3/54, the SK86C M6G offers identical voltage/current ratings and DO-214AB compatibility while maintaining J-STD-020 Level 1 handling and halogen-free compliance-critical for high-volume automated manufacturing.

FAQ
What is the maximum junction temperature rating for the SK86C M6G?
The SK86C M6G has a maximum junction temperature (TJ) rating of +150°C, enabling reliable operation in thermally demanding environments such as enclosed industrial power supplies and LED drivers. This rating is confirmed in the Absolute Maximum Ratings table and applies under continuous forward current conditions with appropriate thermal management. The SK86C M6G must be operated within this limit to ensure long-term reliability and avoid parametric shift.
Does the SK86C M6G have a specified forward voltage at elevated temperature?
Yes-the SK86C M6G specifies a maximum forward voltage of 0.75 V at 8 A and 25°C, and its forward voltage decreases with rising junction temperature due to the negative temperature coefficient of Schottky diodes. While no explicit VF value is given at 100°C, the device maintains stable conduction characteristics across its full –55°C to +150°C operating range, as validated in the Typical Forward Characteristics curve (Fig.4).
Is the SK86C M6G RoHS and halogen-free compliant?
Yes-the SK86C M6G is RoHS compliant and halogen-free per IEC 61249-2-21, as explicitly stated in the FEATURES section of the official Taiwan Semiconductor datasheet (Version L2102). These compliance statements apply directly to the SK86C M6G variant and are verified through material declarations and third-party testing.
What does the "M6G" suffix indicate in SK86C M6G?
The "M6G" suffix in SK86C M6G denotes Taiwan Semiconductor's internal packaging and environmental code: "M" indicates tape-and-reel packaging (3,000 pcs/reel), "6" specifies green molding compound (halogen-free), and "G" confirms RoHS compliance. This coding aligns with TSC's standard ordering nomenclature defined in the Ordering Information section of the SK82C–SK810C datasheet.
Can the SK86C M6G replace the SK85C in an existing design?
Yes-the SK86C M6G can replace the SK85C in most designs because both share identical package (DO-214AB), current rating (8 A), surge rating (150 A), and thermal performance (RθJA = 20 °C/W). The only difference is VRRM: SK85C is rated at 50 V, while SK86C M6G is rated at 60 V. This higher voltage margin provides additional design safety without requiring layout or thermal changes.
