BAS21C Equivalent & Substitute Parts Reference

Part Overview

The BAS21C from Diodes Incorporated is a surface-mount diode array with a 1 pair common cathode configuration, rated for a maximum DC reverse voltage of 250 V and an average rectified current of 200 mA per diode. It features standard technology, a fast reverse recovery time of 50 ns, and is supplied in a SOT-23-3 (TO-236-3, SC-59) package. With its part status marked as obsolete, identifying substitute or equivalent models is required to ensure ongoing production support and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute and equivalent parts for BAS21C are grouped strictly by the following key parameters: diode configuration, voltage ratings, current ratings, reverse recovery time, forward voltage at specified current, leakage current, package type, and environmental compliance status (RoHS, REACH). Mechanical compatibility is addressed by package and mounting type, while regulatory compliance is covered by RoHS and REACH fields.

Parameter Comparison

Engineering Selection Recommendations

The BAS21C part is obsolete. Substitute selection is restricted to products with matching RoHS and REACH compliance, same or compatible package type, and EAR99 export classification. Only substitute parts that fully declare these certifications and statuses in the provided parameters can be included.

Frequently Asked Questions (FAQ)

Q1: What are the main parameters that must match for substituting BAS21C in my design?
A1: Parameters include diode configuration, maximum reverse voltage, average rectified current, forward voltage at specified test current, reverse recovery time, leakage current at specified voltage, package type, mounting type, and environmental compliance certifications.

Q2: Does the difference in diode configuration affect substitution?
A2: Diode configuration (e.g., 1 pair common cathode vs. 1 pair series connection) is a key parameter. Ensure the configuration matches application requirements according to the parameters stated.

Q3: Are the BAS21C and BAV23S-7-F packages directly compatible?
A3: Both devices are specified in TO-236-3, SC-59, SOT-23-3 packages, matching the mechanical footprint for surface-mount assembly.

Q4: What compliance certifications are maintained across BAS21C substitutes?
A4: Both BAS21C and specified substitutes are ROHS3 Compliant and REACH Unaffected, ensuring environmental and regulatory alignment.

Q5: Is there a difference in environmental and export status between BAS21C and its substitutes?
A5: Provided parameters confirm both parts are classified as EAR99 and carry the same environmental and regulatory certifications.
