Breakdown (61.2 V min) is where conduction begins — the device is not a linear regulator, it snaps into conduction above that threshold. Clamping voltage (96.6 V max at 16.5 A peak) is the worst-case voltage across the TVS pins at rated surge current, and is the number the downstream IC or MOSFET gate oxide sees when the event fires. Bidirectional — one active Zener in each direction — so it clamps both positive and negative transients without polarity concern on the board. Power line protection is listed No: this part is not a pass-through bus protector, it is a shunt clamp across the node it guards. ## Obsolete lifecycle — sourcing reality Littelfuse has marked the 1.5SMC68C obsolete. No authorized-stock carry is implied, and the Tape & Reel packaging means any lot found through independent channels is date-code-sensitive — verify the MSL rating before reflow if the lot is aged.","metaTitle":"1.5SMC68C Littelfuse TVS Diode, DO-214AB SMC, 58.1V standoff","metaDescription":"Littelfuse 1.5SMC68C bidirectional TVS Zener diode, DO-214AB SMC, 58.1V standoff, 1.5 kW peak pulse.
