The DO-201AD axial package suits through-hole board layouts common in legacy industrial and telecom power supplies. The 18 V reverse standoff voltage means the diode does not conduct at normal 18 V rail operation, only during overvoltage transients. Operating junction temperature range is -65°C to 175°C, covering extreme environments such as outdoor telecom cabinets or engine-bay electronics where thermal cycling is severe. onsemi lists the ICTE-018G as Obsolete. No official successor part number is published. Date-code spreads and packaging condition (sealed reel vs. cut tape) vary by lot; we confirm at quote time. ## Replacement and cross-reference considerations Because no direct onsemi replacement is published, a functionally equivalent TVS diode must match the 18 V reverse standoff, 21.2 V min breakdown, 30 V max clamping, and 1500 W peak pulse power in a through-hole axial package. A common cross-shop candidate is a 1.5KE18A or similar 1500 W axial TVS from other manufacturers, but verify the clamping voltage and breakdown tolerance against your rail and downstream device withstand.","metaTitle":"ICTE-018G onsemi Mosorb™ Zener TVS Diode – Obsolete, 1500W","metaDescription":"onsemi ICTE-018G Mosorb™ Zener TVS diode, 1500W peak pulse power, 18V reverse standoff, DO-201AD axial.
