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.
