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 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, high reliability/

automotive grade (AEC Q101 qualified)

Terminals: Matte tin plated leads, solderable per

J-STD-002 and JESD22-B102

E3 suffix meets JESD 201 class 1A whisker test, HE3

suffix meets JESD 201 class 2 whisker test

Note: P4KE250 ~ P4KE540A and P4KE250C ~ P4KE440CA for

commercial grade only

Polarity: For uni-directional types the color band

denotes cathode end, no marking on bi-directional

types

DEVICES FOR BI-DIRECTION APPLICATIONS

For bi-direction use C or CA suffix (e.g. P4KE440CA).

Electrical characteristics apply in both directions.
