® MOTOROLA
INTEGRAL DIODE ASSEMBLIES · .. diffused silicon dice interconnected and transfer molded into rectifier circuit assemblies for use in application where high output current/size ratio is of prime importance. These devices feature:
• Void-free, Transfer-molded Encapsulation to Assure High Resistance to Schock, Vibration, and Temperature Extremes
• High Dielectric Strength • Simple, Compact Structure for Trouble-free Performance
• High Surge Capability - 100 Amps
SINGLE-PHASE FULL-WAVE BRIDGE
4 AMPERES 50-600 VOLTS
Designer. Data for "Worst Case" Conditions
The Designers Data Sheet 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.
