Silicon Avalanche Diodes
Unpackaged High Power Transient Voltage Suppressors
15KP CELLS
Designed to protect sensitive electronics which operate
within an environment of lightning induced, short duration,
high current pulses.
The 15KP cell series is specifically designed for high power,
space limited applications. The cell construction provides
three high power T.V.S. die connected in series via heat sink-
ing electrodes.
Devices can be soldered to a substrate via one electrode; con-
nection to the other electrode can then be made by soldering
a suitable jumper.
These devices are designed so they can be used in series/par-
allel configuration in order to provide a very high power
capability that is a far superior solution than using Metal
Oxide Varistors. The low clamping voltage, high speed
response and infinite life (if the maximum rating is not
exceeded) make this ultimate protection for sensitive elec-
tronics.
FEATURES
• 144,000 watts Peak Pulse Power based on 8/20µS (applies
to a single device).
Devices can be arranged in series/parallel to increase
surge handling capability.
