SMCJ64C Equivalent & Substitute Parts Reference

Part Overview

The SMCJ64C is a bidirectional Transient Voltage Suppressor (TVS) diode from Taiwan Semiconductor Corporation, rated at 1500W peak pulse power with a reverse standoff voltage of 64V, a breakdown voltage of at least 71.1V, and a peak pulse current of 13.8A. The device is supplied in a surface-mount DO-214AB (SMC) package and holds an active production status. Substitution may be necessary due to requirements such as supply chain continuity, multiple sourcing, or inventory availability while maintaining strict adherence to the electrical and mechanical parameters specified for the SMCJ64C.

Key Parameters

Substitute Part Grouping Explanation

The substitute devices are selected by matching the following critical parameters for Transient Voltage Suppressors (TVS): TVS diode type (Zener), bidirectional configuration, reverse standoff voltage (64V), minimum breakdown voltage (71.1V), peak pulse power rating (1500W), mounting type (surface mount), and package (DO-214AB/SMC). Only parts that match these key electrical characteristics and mechanical requirements are considered for substitution.

Parameter Comparison

Engineering Selection Recommendations

Both the SMCJ64C and its substitute SMCJ64CA are active status products. They are ROHS3 compliant and REACH unaffected, which ensures regulatory alignment. Both parts have identical physical footprints, electrical configurations, and compliance codes, conforming to EAR99 and HTSUS 8541.10.0080. Selection is supported where substitute parts match in both compliance and provided certifications.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for substituting a TVS diode such as the SMCJ64C?
A1: Substitution is determined by matching the diode type, bidirectional channels, reverse standoff voltage, minimum breakdown voltage, peak pulse power, mounting type, package/case, and compliance status.

Q2: Is the package of SMCJ64C and the substitute SMCJ64CA identical?
A2: Both devices use the DO-214AB (SMC) surface mount package.

Q3: Are both parts compliant with RoHS3 and REACH regulations?
A3: Both SMCJ64C and SMCJ64CA are ROHS3 compliant and REACH unaffected.

Q4: Does substituting SMCJ64C with SMCJ64CA maintain the same electrical ratings for key parameters?
A4: Both parts have the same reverse standoff voltage, minimum breakdown voltage, power rating, and bidirectional capability, with package and temperature ranges also matching.

Q5: Are there any differences in compliance or status that could affect selection?
A5: Both parts have the same compliance status (ROHS3, REACH, ECCN, HTSUS) and active product status.
