1500W bidirectional TVS for 13.6V rail protection
The 1.5SMC16CA-M3/57T: The single bidirectional channel handles symmetrical clamping, so polarity doesn't matter during installation — a practical advantage when the protection is across a floating bus or when the assembly line can't guarantee orientation.
Clamping window and surge current
That 22.5V clamp ceiling is what the downstream silicon sees — a 24V-rated input stage on a DC-DC converter has margin here. The 66.7A peak pulse current is specified with the standard 10/1000µs exponential waveform. Real-world transients (ESD, inductive kickback, lightning-induced surges) have different shapes, but this is the industry benchmark for comparing TVS diodes in this power class.
Package and temperature range
Operating temperature spans -65°C to 150°C junction, covering cold-start conditions and hot enclosures without derating concerns. No power line protection feature is claimed — this is a pure transient suppressor, not a filter.
