With 1500 W peak pulse power and a junction temperature range to 150°C, the part handles the thermal headroom of short-duration industrial transients; the -55°C lower limit covers cold-start and outdoor equipment scenarios where supply rail overshoot is a first-event risk. ## Why this part is now a sourcing decision, not a design decision The 1.5SMC7.5C carries an obsolete product status — it is no longer recommended for new designs and Littelfuse has not published an official direct replacement order code in the ledger. For an active BOM line running this part, the path forward is either independent-distribution surplus stock (lot-traceable where available) or qualification of a pin-compatible alternative in the same DO-214AB SMCJ footprint. Because the 1.5SMC series is a standard SMCJ-form-factor family, any qualified 6.4 V standoff bidirectional TVS in the DO-214AB package is a candidate — the clamping voltage (11.87 V) and peak pulse current (134.5 A) are the gating specs for equivalence; verify both under the same 10/1000 µs test condition before committing to an alternate.","metaTitle":"Littelfuse 1.5SMC7.5C TVS Diode, 6.4V Standoff, DO-214AB","metaDescription":"1.5SMC7.5C is an obsolete Littelfuse bidirectional Zener TVS diode rated 6.4V standoff, 11.87V clamping, 1500W peak pulse in DO-214AB SMC.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Circuit Protection"],"specifications":{"Mfr":"Littelfuse Inc.","Type":"Zener","Series":"1.5SMC","Package":"Tape & Reel (TR)","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"DO-214AB, SMC","Product Status":"Obsolete","lifecycle_stage":"unknown","Power - Peak Pulse":"1500W (1.5kW)","Base Product Number":"1.5SMC","Operating Temperature":"-55°C~150°C(TJ)","Power Line Protection":"No","Bidirectional Channels":"1","Capacitance @ Frequency":"-","Supplier Device Package":"DO-214AB (SMCJ)","Voltage - Breakdown (Min)":"6.75V","Voltage - Clamping (Max) @ Ipp":"11.87V","Voltage - Reverse Standoff (Typ)":"6.4V","Current - Peak Pulse (10/1000µs)":"134.5A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/118f1b70ec0f0941665a20e5472af60a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/1.5SMC7.5C/alternatives.json"},"ai":{"faq":[{"question":"What Littelfuse series does the 1.5SMC7.5C belong to, and what is a typical active replacement?","answer":"The part is part of the 1.5SMC series — a long-running family of 1500 W peak pulse SMCJ TVS diodes. The current active series carrying the same SMCJ package and similar voltage ratings is Littelfuse's SMBJ family, which is the direct form-fit-function replacement in most standoff voltage bins.
