The DO-201AA (DO-27) axial package suits through-hole assembly with a solder joint that handles repeated thermal cycling better than a surface-mount part in high-reliability or high-vibration environments. ## Clamping voltage and the protection margin it leaves When a transient exceeds the breakdown threshold (105V min), the device clamps at 152V max at 10A peak pulse current. That 152V ceiling is what the downstream semiconductor sees: if the load's abs-max rating sits above 152V with margin for derating, the TVS does its job without the load absorbing the surge. Power line protection is not integrated (the 'No' flag on Power Line Protection means this is a basic TVS, not a filtered or multi-stage protector). For AC mains or high-energy transients, pair it with a series fuse or PTC — the TVS handles the voltage spike, the fuse clears the follow-through current. ## Active lifecycle — no LTB clock ticking Littelfuse lists the 1.5KE110A-TB as Active. If a second-source audit is required, several manufacturers offer pin-compatible 1500W axial TVS diodes with the same 94V standoff and 152V clamp — confirm the breakdown voltage tolerance and the 10/1000µs waveform rating match your protection spec.","metaTitle":"Littelfuse 1.5KE110A-TB TVS Diode, 1500W, DO-201","metaDescription":"Littelfuse 1.5KE110A-TB Zener TVS diode, 1500W peak pulse power, 94V standoff, 152V clamp.
