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.","metaTitle":"1.5KE24ARL4G Littelfuse Mosorb TVS, 1500W, 33.2V Clamp","metaDescription":"Littelfuse 1.5KE24ARL4G Mosorb Zener TVS, 1500W peak pulse, 33.2V clamping, DO-201AD axial.
