FDLL485B
General Description: A General Purpose diode that couples high forward conductance fast switching speed and high blocking voltages in a glass leadless LL-34 Surface Mount package. Placement of the Expansion Gap has no relationship to the location of the Cathode Terminal which is indicated by the first color band.
