FDLL485B

General Description: A General Purpose diode that couples high forward

conductance fast switching speed and high blocking RED

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.
