With a reverse standoff of 25.6V and a minimum breakdown of 28.5V, this device protects a 24V nominal bus — the standoff is the continuous DC voltage it blocks without conducting, and the breakdown is where it starts clamping. The unidirectional single-channel design means it only protects against positive transients referenced to ground; a bidirectional rail needs a different part. ## Lifecycle reality — obsolete, no official successor on record Diodes Incorporated lists the 1.5KE30A-T as obsolete. No official replacement part number is published by the manufacturer. ## Package and deployment context — through-hole axial for board-level surge protection The DO-201AA axial package is a through-hole form factor for wave-solder assembly — the lead spacing and body diameter match the standard DO-201 footprint. General-purpose applications — this class of Zener TVS sits on a 24V power bus, a relay coil supply, or a DC motor drive rail to shunt inductive kickback and ESD transients to ground before they reach the controller or sensor electronics.","metaTitle":"1.5KE30A-T Diodes Zener TVS, 1500W 41.4V Clamp","metaDescription":"Obsolete 1.5KE30A-T Zener TVS diode, 1500W peak pulse, 25.6V standoff, 41.4V clamp.
