Its 9.4 V reverse standoff voltage means it sits across a 9 V or 12 V bus without conducting until a transient exceeds the breakdown threshold. That clamp voltage determines the downstream equipment's withstand requirement — anything connected behind this diode must survive a 16.4 V transient without damage. The part is unidirectional with a single anode-cathode pair, housed in a DO-201AA (DO-27) axial-lead through-hole package. The junction operates from -55 °C to 175 °C, covering industrial and automotive under-hood temperature extremes without derating at the upper end. Littelfuse lists the 1.5KE11 as Obsolete.","metaTitle":"1.5KE11 Littelfuse TVS Diode, 1.5kW, 9.4V Standoff","metaDescription":"Littelfuse 1.5KE11 Zener TVS, 1500W peak pulse, 9.4V reverse standoff, DO-201.
