SK86 Schottky Diode 60V 8A SMC Equivalent & Substitute Parts

Part Overview

The SK86 is an active Schottky rectifier diode manufactured by Diotec Semiconductor, rated for 60V DC reverse voltage and 8A average rectified current in a surface mount SMC (DO-214AB) package. This component is designed for fast recovery applications requiring low forward voltage drop and rapid switching characteristics. Substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when alternative packaging formats are required for production flexibility while maintaining electrical and mechanical compatibility within specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SK86 Schottky diode is determined by the following critical electrical and mechanical parameters:

Voltage Rating Compatibility: The substitute part must maintain a DC reverse voltage (Vr) rating of 60V or higher to ensure safe operation in the same circuit topology.

Package Compatibility: The substitute must use the DO-214AB SMC surface mount package to ensure mechanical fit and thermal performance equivalence on the printed circuit board.

Technology Requirement: The substitute must employ Schottky diode technology to maintain the fast recovery switching characteristics and low forward voltage drop inherent to the SK86 design.

Forward Voltage Characteristics: The substitute must operate with a forward voltage (Vf) specification at or below 700 mV to preserve circuit performance and power efficiency.

Recovery Speed: The substitute must meet or exceed the fast recovery specification of ≤ 500ns at currents > 200mA to maintain switching performance in high-frequency applications.

Operating Temperature Range: The substitute must support the junction temperature range of -50°C to 150°C or a range that encompasses this specification.

The B560C-13-F from Diodes Incorporated meets these substitution criteria with the exception of current rating, which is specified at 5A versus the SK86's 8A rating. This substitution is valid for applications where the circuit current demand does not exceed 5A.

Engineering Selection Recommendations

Primary Part Selection: The SK86 remains the preferred component for applications requiring the full 8A current rating. The part is active in production status with 3,847 units in stock, ensuring supply availability.

Substitute Part Selection: The B560C-13-F is suitable as a substitute only for circuit designs where the maximum average rectified current does not exceed 5A. The B560C-13-F offers superior supply availability with 227,807 units in stock and provides an extended operating temperature range (-55°C to 150°C versus -50°C to 150°C). The B560C-13-F is ROHS3 compliant with REACH unaffected status, whereas the SK86 RoHS status is not applicable.

Current Rating Consideration: Applications requiring sustained current operation above 5A must use the SK86 or identify alternative 60V Schottky diodes with 8A or higher current ratings. The B560C-13-F cannot be substituted in high-current applications without risk of thermal stress and component failure.

Reverse Leakage Consideration: The B560C-13-F exhibits higher reverse leakage current (500 µA @ 60V) compared to the SK86 (200 µA @ 60V). Applications sensitive to leakage current performance should retain the SK86 specification.

Packaging Format: The SK86 is supplied in Tape & Reel format, while the B560C-13-F is available in Cut Tape and Digi-Reel formats. Packaging selection depends on production volume and assembly equipment compatibility.

Frequently Asked Questions (FAQ)

Q: Can the B560C-13-F replace the SK86 in all applications?

A: No. The B560C-13-F is rated for 5A average rectified current, while the SK86 is rated for 8A. Substitution is valid only for applications where circuit current demand does not exceed 5A. Exceeding the 5A rating of the B560C-13-F will result in component overstress.

Q: Are the forward voltage characteristics identical between these parts?

A: Both parts specify 700 mV maximum forward voltage, but at different current levels. The SK86 is rated at 700 mV @ 8A, while the B560C-13-F is rated at 700 mV @ 5A. At the B560C-13-F's maximum current of 5A, forward voltage performance is equivalent.

Q: Do these parts use the same package?

A: Yes. Both the SK86 and B560C-13-F use the DO-214AB SMC surface mount package, ensuring mechanical and thermal compatibility on the printed circuit board.

Q: What is the difference in reverse leakage current between these parts?

A: The SK86 exhibits 200 µA reverse leakage at 60V, while the B560C-13-F exhibits 500 µA reverse leakage at 60V. The SK86 has lower leakage current. Applications with strict leakage current specifications should use the SK86.

Q: Are both parts Schottky diodes with fast recovery characteristics?

A: Yes. Both parts are Schottky technology diodes with fast recovery specifications of ≤ 500ns at currents > 200mA, ensuring rapid switching performance in high-frequency rectification circuits.

Q: What is the operating temperature range for each part?

A: The SK86 operates from -50°C to 150°C junction temperature. The B560C-13-F operates from -55°C to 150°C junction temperature. The B560C-13-F provides a 5°C lower minimum temperature specification.

Q: Which part has better supply availability?

A: The B560C-13-F has significantly higher inventory availability with 227,807 units in stock compared to 3,847 units for the SK86. For applications where current requirements permit, the B560C-13-F may offer supply chain advantages.

Q: Are there compliance or certification differences between these parts?

A: The B560C-13-F is ROHS3 compliant with REACH unaffected status and MSL rating of 1 (Unlimited). The SK86 RoHS status is not applicable, and MSL is not applicable. The B560C-13-F provides superior environmental compliance documentation.
