Clamping voltage and pulse power for 94V rail protection
The 1.5KE110CA A0G: The 1500W rating is the peak pulse power the device absorbs without damage under the standard 10/1000 µs surge. On a 94V rail, a transient that clamps at 152V means the TVS shunts up to 10.3A of surge current — enough to handle most secondary-side lightning-induced spikes and inductive load dumps in industrial and telecom gear.
Breakdown tolerance and bidirectional clamping
Minimum breakdown voltage is 105V, with the clamping ceiling at 152V. The 1.5KE110CA A0G is a single bidirectional channel — it clamps both polarities equally, so a single device protects a signal pair or a floating DC bus without needing two diodes back-to-back. The DO-201AA axial package (also known as DO-27) is through-hole, rated for the full 1500W pulse without derating up to 25°C lead temperature.
