TVS clamping thresholds and surge rating
The 1.5SMC100CA V7G: Bidirectional construction means a single device clamps both polarities — suited for AC signal lines or bipolar DC rails where the protection must sink surge energy in either direction.
The 150°C ceiling allows margin in high-duty-cycle clamping events. The DO-214AB (SMC) surface-mount package supports standard reflow profiles; the large copper tab area on the PCB footprint directly influences junction-to-ambient thermal resistance.
The base product number 1.5SMC100 covers both unidirectional and bidirectional variants; the CA suffix and V7G reel designation identify this specific bidirectional, tape-and-reel version.
