Surge rating and voltage thresholds for the BOM line
The 1.5SMC170CA_R1_00001: The 145 V reverse standoff voltage means the device does not conduct at normal rail levels up to that point, so it sits across a 120 VAC or 145 VDC bus without leakage issues. Breakdown starts at 162 V minimum, and the 234 V clamp ceiling defines the voltage the downstream components must survive during a transient. The -55°C to 150°C junction temperature range covers the full industrial thermal envelope and extends into under-hood automotive environments where ambient can hit 125°C with self-heating margin. The single bidirectional channel protects both polarities of an AC line or a bipolar DC rail from a single DO-214AB footprint.
Package and assembly fit
The DO-214AB (SMC) package is a standard surface-mount footprint for reflow soldering, compatible with JEDEC MSL-1 moisture sensitivity level typical for this package class. The Tape & Reel packaging supports automated pick-and-place; the reel quantity is confirmed at order. No special bake-out is required before reflow if the reel seal is intact and the floor life has not been exceeded.
