Equivalent & Substitute Parts for SK23

Part Overview

The SK23, manufactured by Diotec Semiconductor, is a surface-mount Schottky rectifier in the DO-214AA (SMB) package, with a maximum DC reverse voltage of 30 V and a continuous forward current rating of 2A. This device is suitable for fast-recovery rectification applications with junction temperature operation up to 150°C. The product is actively stocked and ROHS3 compliant. In engineering practice, alternative components are selected to support design flexibility, accommodate supply constraints, or qualify products for specific certifications.

Substitute Part Grouping Explanation

Substitute part selection is determined by matching key electrical and mechanical parameters. For Schottky rectifiers such as SK23, the allowable substitute must replicate package type, voltage rating, forward voltage at rated current, recovery speed, leakage current, and mounting type. Matching ROHS and REACH compliance ensures regulatory alignment. These parameters enable direct replacement without adverse impact on system functionality.

Engineering Selection Recommendations

Both SK23 and B330B-13-F are listed as active products and offer ROHS3 compliance and REACH unaffected status. These attributes fulfill regulatory and certification requirements for direct substitution in compliant designs.

Frequently Asked Questions (FAQ)

Q1: What are the essential criteria for substituting a Schottky rectifier part?
The substitution must match voltage rating, current rating, forward voltage, speed, leakage current, mounting type, and package. Compliance certifications (RoHS, REACH) must be identical.

Q2: Are SK23 and B330B-13-F compatible from a package and mounting perspective?
Both parts use the DO-214AA (SMB) surface-mount package and are suitable for direct PCB placement substitution.

Q3: Does the difference in average rectified current affect substitution eligibility?
Substitution is allowed as B330B-13-F offers a higher maximum average rectified current while meeting all other parameters.

Q4: Are the forward voltage and recovery speed compatible for these parts?
Both SK23 and B330B-13-F specify a maximum 500 mV forward voltage at their respective rated currents and fast recovery speed, ensuring compatibility.

Q5: Do compliance and status affect substitute selection?
Yes, only parts with matching active status and regulatory compliance (ROHS3, REACH) are selected as substitutes in engineering applications.
