Key ratings and what they mean for your circuit
The 1.5KE62: A downstream device rated for 100 V or higher has margin; one rated for 80 V does not. Single unidirectional channel in a DO-201AA (DO-27) axial-lead through-hole package. The junction operates from -55°C to 175°C, covering industrial and military temperature ranges without derating at the high end.
Where this class of part is used
General-purpose transient voltage suppression — the 1.5KE62 protects sensitive electronics on a 48 V or 53 V rail from lightning-induced surges, inductive load dumps, and ESD events. Common in power supplies, telecom equipment, industrial controls, and automotive aftermarket modules.
