Rated 1.5 kW peak pulse power in the 10/1000 µs window — a shorter-duration spike at the same energy dumps less current, so the clamp stays lower; a slower front (1000 µs) pulls more current before the TVS limits it, and the clamp moves closer to its maximum. Know your worst-case transient shape before selecting a 1.5 kW part on a 24V line. Operating junction range runs from -50°C to 150°C — the 150°C ceiling gives thermal headroom in enclosed panels or near heat sources that would push a commercial-grade 85°C TVS into derating. The bidirectional configuration means it clamps both polarities on a single polarity rail, so polarity-sensitive circuits get two-direction protection from one device. Listed as Active by Diotec Semiconductor, so no last-time-buy window is currently open. No official second-source or cross-reference successor appears in the ledger for this specific order code.","metaTitle":"Diotec 1.5SMCJ28CA TVS Diode, 28V standoff, 45.4V clamp","metaDescription":"Diotec 1.5SMCJ28CA bidirectional TVS diode, 28V standoff, 45.4V clamp at 33A peak pulse, 1.5 kW.
