That 59.3V ceiling is the number the downstream component's absolute-max rating must clear — if the silicon on the rail is rated for 60V abs-max, this diode holds the margin to a few hundred millivolts at the peak. ## Package, temperature grade, and the DO-201AE axial footprint Housed in a DO-201AE axial-lead package, the 1.5KE43A-TP mounts through-hole — the body sits off the board, relying on the lead wires and the copper trace area for heat sinking during the pulse. The junction temperature range spans -55°C to +175°C, covering the full industrial and military temperature envelope; the 175°C ceiling is the silicon's survival limit, not a continuous operating target. The axial form factor is standard for through-hole TVS insertion; the lead bend and standoff height are set by the assembly house, not the part itself. No power line protection feature is declared — this is a signal-rail or low-voltage bus protector, not a mains-side suppressor. ## Active production — sourcing posture for the BOM line No official second-source or pin-compatible cross-reference is published by the manufacturer — if a backup is needed, the parametric fit (standoff voltage, clamping, package) must be matched by the buyer against other 1.5KE43A-spec parts from different brands.","metaTitle":"Micro Commercial Co 1.5KE43A-TP, 1500W TVS Diode","metaDescription":"1.5KE43A-TP unidirectional Zener TVS, 1500W peak pulse, 36.8V standoff, 59.3V clamp.
