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.
