The 96.6 V clamping ceiling means a 48 V nominal bus or a 60 V DC rail with a 20 % tolerance stays below the clamp threshold during normal operation, but a surge that drives the line above 61.2 V is shunted before it reaches the protected circuit's absolute maximum. ## Temperature range and package fit Housed in a DO-201AA (DO-27) axial-lead package, through-hole mounted. The DO-201 footprint is larger than the smaller SMAJ/SMBJ surface-mount TVS, which means higher surge capability but a manual insertion step in assembly.","metaTitle":"Littelfuse 1.5KE68 Zener TVS, 1500W, DO-201, Obsolete","metaDescription":"Littelfuse 1.5KE68 Zener TVS diode, 1500W peak pulse, 58.1V standoff, DO-201 axial.
