Supplied in a DO-201AA (DO-27) axial-lead package, through-hole mounted. The axial format suits point-to-point wiring on terminal boards or through-hole PCB layouts where a surface-mount TVS would not survive the same surge energy.","metaTitle":"Littelfuse 1.5KE550 TVS Diode, 495V Standoff, 798V Clamp","metaDescription":"Obsolete Littelfuse 1.5KE550 Zener TVS diode, 1500W peak pulse, 495V standoff, 798V clamp.
