P4KE Series

TRANSIENT VOLTAGE SUPPRESSORS

Features

• Glass passivated junction

• 400 W pulse capability on 10/1000 µs wave form

• Excellent clamping capability

• Low Zener impedance

• Fast response time

Mechanical Data

• Case: DO-41 molded plastic body

• Terminals: Solder axial plated, solderable per MIL-STD-750,

method 2026

• Polarity: Color band denotes cathode end

Devices for bidirectional applications

• For bidirectional use C or CA suffix for types P4KE6.8 thru types P4KE440A (e.g. P4KE6.8C, P4KE440CA)

• Electrical characteristics apply in both directions
