Key Parameters

Substitute Part Grouping Explanation

Substitute parts for SMLJ54CA-TP are grouped based on strict equivalence in critical electrical and mechanical parameters. Substitution is determined by matching the following key parameters: device type, bidirectional channel count, reverse standoff voltage (typical), minimum breakdown voltage, maximum clamping voltage at specified peak pulse current, peak pulse current, maximum peak pulse power, mounting type, and package configuration. Only parts explicitly matching these criteria are considered suitable substitutes within the TVS diode product category.

Parameter Comparison

Engineering Selection Recommendations

Both SMLJ54CA-TP and SMDJ54CA are classified as "Active" and have matching compliance designations, including REACH Unaffected and EAR99. SMDJ54CA is referenced as ROHS3 compliant based on the available details and shares the same protection category and packaging type as SMLJ54CA-TP. Engineering selection can be based on inventory availability, compliance documentation, and package compatibility within documented status fields.
