Clamping and current handling
The 1.5SMC30CA-Q: This means a 24V nominal rail sees the transient clipped to under 42V, staying well within the breakdown margin of downstream 40V-rated components. The single bidirectional channel protects both polarities — no need for two diodes in anti-series — saving board space in tight automotive ECU or telecom line-card layouts.
Package and mounting
The supplier device package is identical to the case code, so the footprint matches existing SMC pads without a layout change. Supplied in Tape & Reel (TR) for automated pick-and-place assembly — no manual handling required for volume production.
For BOM hedging, the AEC-Q101 qualification ensures a single-source risk flag is low, but a parametric equivalent from another manufacturer can be evaluated at RFQ.
