1500 W peak pulse in a DO-201AD axial package
The 1.5KE24ARL4G: The 1500 W rating means this part absorbs high-energy transients — a direct lightning strike or inductive load dump — without failing short. The 33.2 V clamp voltage protects downstream 24 V rails from exceeding the absolute maximum of most DC-DC converters and linear regulators.
Lifecycle reality — obsolete, sourced to order
Littelfuse lists the 1.5KE24ARL4G as Obsolete.
Package and deployment context
Housed in a DO-201AD axial-lead package, the 1.5KE24ARL4G mounts through-hole on a PCB. The axial form factor is common in power-supply input stages and telecom line cards where the TVS sits between the transient source and the protected circuit. Operating temperature spans -65°C to 175°C (junction), covering military and industrial thermal extremes. The wide range suits outdoor telecom cabinets, engine-bay electronics, and avionics power buses.
