The 1.5KE160CA-E3/73: The minimum breakdown voltage is 152 V, so the protection threshold is well above the 136 V standoff to avoid nuisance triggering on normal rail ripple. No power line protection feature is built in, so it is best suited for secondary-side or board-level clamping rather than mains primary protection.
For BOM planning, the through-hole DO-201AA package is a mature, widely stocked form factor.
