This voltage stack gives a 12 V rail about 3 V of headroom before conduction starts, with the clamp hard-limiting transients below 23 V. ## Last-buy lifecycle — plan the BOM transition Vishay has placed the 1.5KE16CA-/51 into Last Buy status. New designs should not target this order code; existing BOM lines need a replacement strategy before the remaining inventory is exhausted. No official successor order code is recorded in the lifecycle data, so a parametric cross-reference (same 1.5 kW, 13.6 V standoff, bidirectional, DO-201AA package) is the practical migration path. ## DO-201AA axial-lead — board-fit constants Through-hole mounting in a DO-201AA (DO-27) axial-lead package. The 1.5KE body diameter and lead spacing are standard for this power class — the hole pattern and lead bend radius match existing TVS footprints on 12 V and 24 V input rails. The junction temperature margin at 1500 W pulse is generous for short-duration transients; repetitive pulsing requires derating per the datasheet curve.","metaTitle":"Vishay 1.5KE16CA-E3/51 TransZorb TVS, 1.5kW, 13.6V","metaDescription":"Vishay 1.5KE16CA-E3/51 bidirectional TVS diode, 1500W peak pulse, 13.6V standoff, DO-201AA.
