Product details
Overview
SK86CHM6G from Taiwan Semiconductor is an 8A, 60V Schottky barrier surface-mount rectifier in DO-214AB (SMC) package, designed for high-efficiency DC/DC conversion with low forward voltage (0.75 V at 8 A, 25°C), high surge capability (150 A), and junction temperature rating up to +150°C. It serves as a primary output rectifier in compact AC/DC adapters and industrial SMPS.
For engineers reviewing the SK86CHM6G datasheet, SK86CHM6G pinout, SK86CHM6G application, or SK86CHM6G equivalent, key selection criteria include its 60 V repetitive peak reverse voltage, 0.75 V forward drop at rated current, 10,000 V/µs dV/dt rating, moisture sensitivity level 1 compliance, and RoHS/halogen-free qualification - all critical for high-density, thermally constrained power designs.
Technical Context
The SK86CHM6G implements a single-die Schottky junction optimized for low conduction loss in continuous forward-biased operation. Its guard ring structure enhances ruggedness against transient overvoltage events, while the matte tin-plated leads ensure reliable solderability per J-STD-002.
Thermally, it features a junction-to-ambient thermal resistance of 20°C/W under standard PCB mounting conditions, enabling stable operation at 8 A DC with appropriate copper area. The device operates across –55°C to +150°C junction temperature range and meets JESD201 Class 2 whisker resistance requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 60 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in flyback/freewheeling paths |
| IF | 8 A - Continuous average forward current; supports high-power adapter and converter outputs without derating at TA ≤ 50°C |
| IFSM | 150 A - Non-repetitive surge current (8.3 ms half-sine); withstands inrush and fault transients in SMPS |
| VF | 0.75 V @ 8 A, 25°C - Low conduction loss directly reduces power dissipation and improves system efficiency |
| TJ max | +150°C - Extended junction temperature rating enables use in sealed or high-ambient environments |
| dV/dt | 10,000 V/µs - High critical rate-of-rise immunity prevents false turn-on during fast-switching node transitions |
| RθJA | 20°C/W - Thermal performance baseline for layout design; requires ≥1.5 cm² 2-oz copper pad for full 8 A rating |

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-M3/45 | Same 60 V VRRM, 8 A IF, but TO-277 package (smaller footprint, higher RθJA = 25°C/W) | Preferred where board space is constrained but thermal margin is available via forced air or copper spreading | Select when footprint reduction outweighs thermal derating needs; not drop-in due to different pad layout |
| ON Semiconductor SB860-E3/54 | Identical DO-214AB package and 60 V/8 A rating, but VF = 0.72 V (typ) at 8 A - 30 mV lower conduction loss | Better suited for ultra-high-efficiency designs where <0.1% efficiency gain justifies sourcing change | Valid alternative with same pinout and thermal profile; verify IR spec (0.5 mA max @ 25°C) matches system leakage budget |
Compared with VS-8EWH06FN-M3/45 and SB860-E3/54, the SK86CHM6G offers balanced trade-offs: identical package compatibility with SB860-E3/54 but slightly higher VF, and superior thermal resistance versus VS-8EWH06FN-M3/45 - making it optimal for convection-cooled, space-constrained industrial power supplies.

FAQ
What is the maximum junction temperature rating for SK86CHM6G?
The SK86CHM6G has a maximum junction temperature (TJ) rating of +150°C, allowing operation in high-ambient environments such as enclosed power supplies or industrial enclosures. This rating is confirmed in the Absolute Maximum Ratings table and applies under both continuous and pulsed conditions, provided thermal design maintains junction temperature within this limit. The SK86CHM6G must be mounted on adequate copper area to achieve full 8 A current capability at elevated ambient temperatures.
Does SK86CHM6G meet RoHS and halogen-free requirements?
Yes, the SK86CHM6G is RoHS compliant and halogen-free per IEC 61249-2-21. These qualifications are explicitly stated in the FEATURES section of the official Taiwan Semiconductor datasheet (Version L2102). The device uses matte tin-plated leads and halogen-free molding compound, satisfying environmental compliance mandates for export to EU, China, and other regulated markets. No exemptions apply - full substance-level compliance is verified.
What is the forward voltage of SK86CHM6G at 8 A and 25°C?
The forward voltage (VF) of the SK86CHM6G is 0.75 V maximum at 8 A forward current and 25°C junction temperature, as specified in the ELECTRICAL SPECIFICATIONS table. This value is measured under pulse test conditions (PW = 0.3 ms) and represents worst-case conduction loss for thermal and efficiency calculations. At higher temperatures (e.g., 100°C), VF decreases slightly, improving conduction efficiency under thermal stress.
Is SK86CHM6G suitable for use in high-dV/dt environments like flyback converters?
Yes, the SK86CHM6G is rated for a critical rate-of-rise of off-state voltage (dV/dt) of 10,000 V/µs, making it suitable for high-speed switching topologies including flyback, forward, and active-clamp converters. This specification ensures immunity to false turn-on caused by rapid voltage transients across the device during switching node ringing. The guard ring structure further enhances ruggedness against such stress, as documented in the FEATURES section.
What packaging and moisture sensitivity level does SK86CHM6G have?
The SK86CHM6G is supplied in DO-214AB (SMC) package and 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 or baking prior to reflow. This simplifies SMT line integration and eliminates MSL-related handling overhead. The device ships in 3,000-piece tape-and-reel format, compatible with standard pick-and-place equipment.
