The 51.4 A peak pulse rating at the standard 10/1000 µs wave shape tells you how much current the clamp can shunt during the event — a higher Ipp figure means the device handles larger transient energy without degradation, so this rating is the key sizing parameter when you are protecting a bus that sees inductive kickback or ESD injection. ## 1500 W peak pulse in the SMC footprint — thermal reality Single unidirectional channel means this device protects one rail polarity — a positive-going transient on a powered rail, or a negative clamp to ground. If your circuit needs bidirectional protection on the same node you would need the two-diode variant in the same series. ## Sourcing posture — active, no cross-reference on record Panjit International Inc. lists this part as Active with no official last-time-buy or end-of-life notice in the ledger. The 1.5SMCJ series is a widely-cloned TVS family, so multiple manufacturers offer pin-compatible equivalents at the same standoff and clamp voltage — confirming the exact part-number match is the BOM-line decision. No stock-holding claim or immediacy promise. Confirm the date code and packaging variant (tape-and-reel vs cut tape) before committing a production run.","metaTitle":"Panjit 1.5SMCJ18A_R1_00001, 18V Zener TVS Diode, SMC","metaDescription":"Zener TVS diode, 18V standoff, 29.2V clamping @ 51.4A peak pulse.

The deciding factors for interchangeability are the 18 V standoff, the 29.2 V clamping maximum, and the 51.4 A peak pulse rating — the datasheet confirms these three parameters before substituting a second-source brand, since surge capability and clamping characteristics can vary at the part-number level even when the package and voltage class match."},{"question":"How can I check stock or request a quote for 1.5SMCJ18A_R1_00001?","answer":"Availability and current lead times confirmed at RFQ — specify the required packaging variant (tape-and-reel or cut tape) when you submit the request, since both are listed in the manufacturer's standard packaging options."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/panjit-international-inc/1.5SMCJ18A_R1_00001","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/panjit-international-inc/1.5SMCJ18A_R1_00001 when reusing this data.
