What makes the 1.5SMC82CA_R1_00001 different
The 1.5SMC82CA_R1_00001 is a unidirectional Zener-based TVS diode — the CA suffix confirms bidirectional polarity, so it clamps both polarities of surge voltage. Rated 1500 W peak pulse (10/1000 µs waveform) — this is the energy-absorption ceiling that determines whether the part survives a IEC 61000-4-5 surge test in your system. A 1.5 kW TVS sits at the mid-range of the 1.5SMC family, protecting rails above what lower-rated series can handle while remaining manageable on a standard SMC land pattern. This grade avoids derating in most industrial enclosure designs without active cooling.
SMC (DO-214AB) package is the standard two-terminal J-bend footprint — the cathode band marks polarity on the sleeve, and the part reflows on a standard Sn lead-free profile. The wide temperature rating means the die attach and mold compound are stable across multiple reflow cycles without re-cracking, which matters if the board sees rework. Tape-and-reel packaging with a cut-tape option — the reel suits high-volume SMT line feeding; the single-unit cut-tape variant serves kitting and small-lot board spin work.
