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.
MECHANICAL DATA
Case: DO-204AL, molded epoxy body over passivated chip
Molding compound meets UL 94 V-0 flammability rating
Base P/N-E3 - RoHS-compliant, commercial grade
Base P/NHE3 - RoHS-compliant, AEC-Q101 qualified
DEVICES FOR BI-DIRECTION APPLICATIONS
For bi-directional types, use CA suffix (e.g. P4KE440CA).
Electrical characteristics apply in both directions.
Terminals: Matte tin plated leads, solderable per
J-STD-002 and JESD 22-B102
E3 suffix meets JESD 201 class 1A whisker test, HE3 suffix
meets JESD 201 class 2 whisker test
Note
• P4KE250CA to P4KE540A and P4KE250A to P4KE440CA for
commercial grade only
Polarity: For uni-directional types the color band denotes
cathode end, no marking on bi-directional types
