The reverse standoff voltage is 13.6V, meaning the diode will not conduct appreciably below that level during normal operation. Breakdown starts at a minimum of 14.4V, so the protection triggers cleanly above the working rail voltage. ## Package and board-fit: DO-201 axial through-hole Housed in a DO-201AA / DO-27 axial leaded package, the 1.5KE16 is a through-hole part suited for board-level transient protection where wave-solder or hand-solder assembly is the norm. The DO-201 body is larger than the smaller DO-41 or SMA packages, handling the 1500W pulse without thermal fatigue. A single unidirectional channel covers one signal or power rail. For bidirectional protection, two diodes in anti-series are needed. ## Temperature range and deployment environment The wide TJ range means the clamping performance and leakage remain stable across temperature swings.","metaTitle":"Littelfuse 1.5KE16 TVS Diode, 1500W, DO-201, Obsolete","metaDescription":"Littelfuse 1.5KE16 Zener TVS diode, 1500W peak pulse power, 13.6V standoff, DO-201 axial.
