The single unidirectional channel protects one signal or power rail per device. ## Temperature range and general-purpose use No power line protection — intended for signal and low-voltage DC rail transient suppression, not AC mains.","metaTitle":"1.5KE33A-T Diodes Inc TVS Diode, 1500W, 28.2V Standoff","metaDescription":"Diodes Inc 1.5KE33A-T Zener TVS, 1500W peak pulse, 28.2V standoff, DO-201 axial.
