DEVICES FOR BI-DIRECTION APPLICATIONS
For bidirectional types, use CA suffix (e.g. P4KE440CA). Electrical characteristics apply in both directions.
TYPICAL APPLICATIONS
Use in sensitive electronics protection against voltage transients induced by inductive load switching and lighting on ICs, MOSFET, signal lines of sensor units for consumer, computer, industrial, automotive, and telecommunication.
