Reverse standoff voltage is 5.8V — the diode remains non-conducting below this level, so a 5V rail stays clean during normal operation. Breakdown occurs at 6.45V minimum, clamping the transient to 10.5V maximum before the TVS conducts the surge current to ground. AEC-Q101 qualification means the device has passed automotive-grade reliability screening: temperature cycling, high-temperature reverse bias, and ESD robustness per the automotive IC standard. ## Package and board integration Through-hole DO-201AA (DO-27) axial package — the leads insert into plated through-holes on the PCB and are wave-soldered. The bulk packaging means parts are loose in a tube or bag, not taped-and-reeled; plan for manual or tube-fed placement, not automated pick-and-place from a reel. Single unidirectional channel — one TVS diode per package, cathode banded. For bidirectional protection on an AC or bipolar rail, two devices in anti-series or a dedicated bidirectional part is needed.","metaTitle":"Vishay 1.5KE6.8AHE3/51 TVS Diode, 1500W, 10.5V Clamp","metaDescription":"Obsolete Vishay 1.5KE6.8AHE3/51 1500W unidirectional TVS, 5.8V standoff, 10.5V clamp, AEC-Q101, DO-201AA.
