P r o d u c t I n n o v a t i o n F r o m
Six 100V Schottky diodes conduct the commutation current via low forward voltage paths which reduces the power
dissipation in the SA57. These diodes are rated for 5A continuous and are mounted close to the SA57 to reduce
inductance 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 dissipa-
tion are manageable during commutation cycles.
Figure 4 shows the top and bottom layouts of the DB63R. Gerber files for the circuit board are available upon re-
quest.
