Clamping performance and pulse handling
The 1.5SMC160CAHM3/I: The 152 V minimum breakdown voltage and 136 V reverse standoff mean it stays transparent on a 136 V nominal rail and only conducts when a transient pushes the line above 152 V. Single bidirectional channel — one device clamps both polarities, saving board space versus two unidirectional diodes in anti-series. The -65°C to 150°C junction temperature range covers the full automotive ambient envelope.
