DB64
electrolytic capacitors provide a local, low inductance source to accommodate surge currents up to 17A. Six 100V
Schottky diodes conduct the commutation current via low forward voltage paths which reduces the power dissipa-
tion in the SA306. These diodes are rated for 5A continuous and are mounted close to the SA306 to reduce induc-
tance in the commutating current loop. For applications with continuous currents less than 5A, the Schottky diodes
may not be necessary if the higher forward voltage internal body diodes and the associated power dissipation are
manageable during commutation cycles.
