SK86C Schottky Diode Equivalent & Substitute Parts

Part Overview

The SK86C is an active Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, rated for 60V DC reverse voltage and 8A average rectified current in a surface mount DO-214AB (SMC) package. This component is designed for fast recovery applications with switching speeds ≤500ns and operates across a junction temperature range of -55°C to 150°C. The SK86C is ROHS3 compliant and carries unlimited moisture sensitivity level (MSL 1) classification, making it suitable for standard industrial and commercial applications. Alternative equivalent and substitute parts are identified to support procurement flexibility, design redundancy, and supply chain continuity.

Substitute Part Grouping Explanation

Substitute parts for the SK86C are classified into two categories based on electrical parameter alignment:

Direct Equivalent (SK86C by MDD): This substitute maintains identical electrical specifications including 60V reverse voltage rating, 8A average rectified current, fast recovery speed classification (≤500ns, >200mA), and surface mount SMC packaging. The part shares the same base product number designation and carries equivalent compliance certifications (ROHS3, MSL 1). This classification supports direct one-to-one replacement in circuit designs without derating or functional compromise.

Similar Substitute (B360Q-13-F by Diodes Incorporated): This substitute shares the 60V reverse voltage rating, fast recovery speed classification, SMC package form factor, and identical operating temperature range. However, the current rating is reduced to 3A average rectified current, representing a 62.5% reduction from the SK86C specification. This part is qualified to automotive grade AEC-Q101 standard and carries identical compliance status. This classification applies to applications where the 8A current requirement can be reduced or where redundant parallel configurations are implemented.

Substitution eligibility is determined by matching the following critical parameters: reverse voltage rating (60V), package type (DO-214AB/SMC surface mount), technology (Schottky), speed class (fast recovery ≤500ns), and operating temperature range (-55°C to 150°C).

Parameter Comparison

Engineering Selection Recommendations

SK86C (MDD Equivalent): This direct equivalent substitute is suitable for applications requiring identical electrical performance to the original Taiwan Semiconductor Corporation SK86C. Both parts maintain 60V/8A specifications, identical speed classification, and equivalent compliance certifications. Selection of the MDD variant is appropriate when supply constraints affect the primary manufacturer or when procurement strategy requires qualified alternative sources. Both parts carry ROHS3 compliance and unlimited moisture sensitivity classification, supporting deployment in standard industrial environments without additional qualification requirements.

B360Q-13-F (Diodes Incorporated Similar Substitute): This substitute is applicable to circuit designs where the average rectified current requirement is 3A or lower, or where the application topology supports parallel device configurations to achieve higher current capacity. The B360Q-13-F carries automotive-grade AEC-Q101 qualification, providing enhanced reliability documentation suitable for mission-critical or automotive applications. The identical 60V reverse voltage rating, SMC package form factor, and operating temperature range ensure mechanical and thermal compatibility. Selection of this part is appropriate when automotive-qualified components are specified or when current derating is acceptable within the circuit design margin.

Frequently Asked Questions (FAQ)

Q: Can the SK86C (MDD) be used as a direct replacement for the SK86C (Taiwan Semiconductor Corporation)?

A: Yes. Both parts share identical electrical specifications: 60V reverse voltage, 8A average rectified current, fast recovery speed classification (≤500ns, >200mA), DO-214AB/SMC surface mount package, and -55°C to 150°C operating temperature range. Both carry ROHS3 compliance and MSL 1 classification. Direct one-to-one substitution is supported without circuit modification.

Q: What are the limitations of using the B360Q-13-F as a substitute for the SK86C?

A: The B360Q-13-F is rated for 3A average rectified current compared to the SK86C's 8A rating. This represents a 62.5% reduction in current capacity. The B360Q-13-F is suitable only for applications where the circuit current requirement does not exceed 3A, or where multiple devices are configured in parallel to achieve higher aggregate current capacity. All other electrical parameters, package form factor, and operating temperature range remain compatible.

Q: Are all three parts compatible with the same PCB footprint?

A: Yes. All three parts use the DO-214AB (SMC) surface mount package, which defines identical PCB land pattern, solder pad geometry, and component placement requirements. No PCB redesign is required when substituting between these parts.

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

A: The SK86C (Taiwan Semiconductor) and B360Q-13-F both specify 500 µA reverse leakage at 60V. The SK86C (MDD) specifies 1 mA reverse leakage at 60V, representing a 2x increase. This difference may be significant in low-leakage or precision analog applications but is typically acceptable in standard rectifier and power conversion circuits.

Q: Does the B360Q-13-F automotive qualification (AEC-Q101) affect its use in non-automotive applications?

A: No. AEC-Q101 qualification represents an additional quality and reliability standard that exceeds standard industrial requirements. Parts qualified to automotive standards are suitable for use in non-automotive applications without restriction. The automotive qualification does not limit or constrain application scope.

Q: What compliance certifications apply to all three substitute options?

A: All three parts carry ROHS3 compliance, REACH Unaffected status, MSL 1 (unlimited moisture sensitivity), and EAR99 export classification. These certifications support deployment in regulated industrial, commercial, and consumer applications without additional compliance documentation.
