This is a unidirectional Zener TVS — it protects one polarity only. ## DO-214AA SMB footprint and board-fit The junction temperature range spans -65°C to 150°C, covering telecom outdoor cabinets, industrial enclosures, and equipment that sees thermal cycling. ## Where it fits — telecom and DC-rail surge protection Littelfuse explicitly lists Telecom as the target application. The 1500 W pulse rating and 85.5 V standoff make it a natural fit for protecting 48 V DC telecom rectifiers, base-station power feeds, and line-card interfaces against lightning-induced transients and inductive load dumps. The same ratings suit it for industrial DC bus protection in 60-72 V systems.","metaTitle":"Littelfuse 1.5SMB100A TVS Diode, 1500W, DO-214AA","metaDescription":"Littelfuse 1.5SMB100A Zener TVS diode, 1500W peak pulse, 85.5V standoff, 137V clamp, DO-214AA SMB.
