GENERAL DESCRIPTION
Dual, common cathode schottky rectifier diodes in a conventional leaded plastic package and a surface mounting
plastic package. Intended for use as output rectifiers in low voltage, high frequency switched mode power supplies.
The PBYR1545CT series is supplied in the SOT78 conventional leaded package.
The PBYR1545CTB series is supplied in the SOT404 surface mounting package.
