The 5.8 V standoff voltage means the diode draws negligible leakage below that level, so it does not load a 5 V rail during normal operation. Clamping at 10.5 V ensures downstream components rated for 12 V or higher survive the event. ## Package and board integration Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE6.8A-TB is a through-hole device suited for point-to-point wiring or PCB mounting with 0.040-inch diameter leads. The Bulk packaging means it ships loose in a bag or tube — not tape-and-reel, so hand-placement or wave-solder assembly is straightforward.","metaTitle":"1.5KE6.8A-TB Littelfuse 1500W TVS Diode, 6.8V","metaDescription":"Littelfuse 1.5KE6.8A-TB 1500W TVS diode, 6.45V breakdown, 10.5V clamping, DO-201 axial.
