Housed in a DO-201AD axial-lead package, it operates across -65°C to 175°C junction temperature — suitable for industrial and telecom environments where board temperatures climb. onsemi lists the 1N6288ARL4 as Obsolete. Sourcing relies on verified distributor shelf stock or the secondary market. The base product number is 1N6288; the 'ARL4' suffix denotes a specific packaging and lead-finish variant. Buyers should confirm date code and package integrity when procuring from non-franchised channels. ## Clamping voltage and peak pulse current — what they mean for protection With a 70.1V max clamping voltage at 21.4A peak pulse, this TVS protects 48V bus lines and downstream DC-DC converters from surges. The 1500W rating covers the energy in a typical lightning-induced transient on outdoor telecom or industrial control wiring. No power line protection — this is a unidirectional device for signal or low-voltage DC rails, not AC mains.","metaTitle":"1N6288ARL4 Zener TVS – 1500W, 43.6V Standoff","metaDescription":"onsemi 1N6288ARL4 is a 1500W peak pulse Zener TVS, 43.6V reverse standoff, clamping at 70.1V.
