A 48 V or 72 V telecom bus, or a 90 V nominal DC link, stays below the standoff and the TVS stays dark until a transient pushes the rail above 105 V. ## Bidirectional — one device covers both polarities Single bidirectional channel — the 1.5KE110CA clamps positive and negative transients symmetrically. On an AC signal line or a floating DC bus where the return can swing negative, one part replaces two unidirectional TVS diodes back-to-back. The DO-201AA axial leaded package (DO-27 equivalent) inserts into a through-hole board with standard 0.100-inch lead spacing. Operating junction temperature range spans -55°C to 175°C — the full industrial temperature band plus margin. In an outdoor telecom cabinet that sees 85°C internal ambient, the junction stays well within the derating curve. The through-hole axial body conducts heat into the PCB traces; a 1-ounce copper pad on each lead pulls heat out of the die during repetitive surge events.","metaTitle":"1.5KE110CA Littelfuse TVS Diode, 1500W, Bidirectional","metaDescription":"Littelfuse 1.5KE110CA bidirectional TVS diode, 1500W peak pulse power, 94V standoff, DO-201AA.
