With a breakdown voltage of 6.45V minimum and clamping at 10.5V maximum at 150A peak pulse current (10/1000µs waveform), it protects downstream silicon from surges that exceed the rail's absolute maximum rating. ## Clamping voltage and peak current envelope The 1500W peak pulse power is the product of clamping voltage and peak current; derate this for higher ambient temperatures per the datasheet curve. The 5.8V reverse standoff is the maximum DC voltage the diode blocks without conducting — at 5.8V the leakage is negligible, so it sits across a 5V supply rail without draining the battery. The 6.45V minimum breakdown guarantees the avalanche triggers before the rail hits 7V, catching transients before they reach the load. ## DO-201 axial package and board integration The DO-201AA / DO-27 axial package is a through-hole form factor with a 0.052-inch lead diameter — it mounts into a 1.0mm drilled hole on a standard PCB or terminal block. The axial leads allow either vertical or horizontal mounting; the body length is about 7.5mm, so it fits between board-edge connectors or alongside electrolytic capacitors in a power supply layout. Bulk packaging means the parts ship loose in a bag or tube — no reel, no carrier tape. For a rework bench or low-volume assembly, this is fine; for automated pick-and-place, the axial leads require a radial-tape conversion or hand-insertion.","metaTitle":"1.5KE6.8AHB0G TVS Diode, 1500W, DO-201, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5KE6.8AHB0G automotive Zener TVS, 1500W peak pulse, 6.45V breakdown, DO-201 axial.
