With a peak pulse power rating of 1500W (1.5kW) under the 10/1000µs waveform, it handles substantial surge energy from lightning, inductive load switching, or ESD coupling in industrial and telecom equipment. Breakdown occurs at a minimum of 21.2V, and clamping is limited to 30V at the peak pulse current of 50A (8/20µs waveform). ## Obsolete — last-time-buy window closed, source through independent channels onsemi lists the ICTE-18RL4G as Obsolete. No official successor is cited in the available records, so procurement should treat this as a last-time-buy situation: any remaining stock in distribution is the remaining supply. The axial package is still common in the Mosorb family, so a parametric cross to a similar Zener TVS with the same footprint is possible, but pin-compatibility must be verified per the specific circuit. ## Package and mounting — DO-201AD axial for through-hole assembly The axial package is a through-hole form factor with two leads, rated for the full 1500W pulse without derating when mounted with adequate lead length and board copper. The axial body allows insertion into plated through-holes on single or double-sided boards, and the lead spacing is standard for this JEDEC outline.","metaTitle":"ICTE-18RL4G onsemi Zener TVS Diode 1500W 18V DO-201AD","metaDescription":"onsemi Mosorb™ Zener TVS diode, 1500W peak pulse power, 18V reverse standoff, 30V clamping, DO-201AD axial.
