Breakdown starts at 12.4V minimum, providing a 1.3V guard band above the 12V nominal bus before the TVS begins conducting. The maximum clamping voltage of 18.2V limits the transient stress on downstream components — a 12V-rated ECU input with 20V abs-max survives this clamp level without external series protection. The single bidirectional channel means both polarities are clamped in one device — useful for AC-coupled signal lines or power rails where reverse-voltage events are possible. No power-line protection flag indicates this is a general-purpose transient suppressor, not a dedicated rail-clamp array with integrated filtering. ## Through-hole package and board integration Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE13CAHA0G mounts through-hole. The DO-201 body handles the 1500W pulse without cracking the epoxy — the lead frame and die attach are sized for the thermal pulse energy. Tape & Box packaging is the standard reel-less format for axial diodes; the leads are taped between carrier strips for automated insertion, not wound on a reel.","metaTitle":"1.5KE13CAHA0G TVS Diode, 1500W, Bidirectional, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE13CAHA0G automotive AEC-Q101 bidirectional TVS, 11.1V standoff, 18.2V clamp, 86A peak pulse.
