MOA920Al thru MOA920A9 ® MOTOROI.A Designers Data Sheet MINIATURE INTEGRAL DIODE ASSEMBLIES II passivated, diffused-silicon dice interconnected and transfer molded into void less hybrid rectifier circuit assemblies. • Large Inrush Surge Capability - 45 A (For 1.0 Cycle) • Efficient Thermal Management Provides Maximum Power Handling in Minimum Space Designers Data for "Worst Case" Conditions The Designers DataSheet permits the design of most circuits entirely from the information presented. Limit curves - representing boundaries on device characteristics - are given to facilitate "worst case" design. MAXIMUM RATINGS Rating IPer Legl Symbol AI A2 A3 A4 A5.

AMBIENT TEMPERATURE (DC) FIGURE 7 - BASIC CIRCUIT USES FOR BRIDGE RECTIFIERS Load 1 load 2 CIRCUIT A CIRCUIT B APPLICATION NOTE The Data of Figure4 applies for typical wire terminal or printed circuit board mounting conditions in still air. Under these or simi· lar conditions, the thermal resistance between the diode junctions and the leads at the edge of the case is a small fraction of the thermal resistance from junction to ambient. Consequently. the lead temperature is very close to the"junction.
