APPLICATION NOTES
This series of Silicon Transient Suppressors is
used in applications where large voltage transients
can
permanently
damage
voltage-sensitive
components.
The TVS diode can be used in applications where
induced lightning on rural or remote transmission
lines presents a hazard to electronic circuitry (ref:
R.E.A. specification P.E. 60).
This Transient Voltage Suppressor diode has
a pulse power rating of 1500 W for 1 ms. The
response time of TVS diode clamping action
is
effectively
instantaneous
(1
x
10-9
s
bi-directional);
therefore,
they
can
protect
integrated circuits, MOS devices, hybrids, and
other
voltage
sensitive
semiconductors
and
components. TVS diodes can also be used in
series or parallel to increase the peak power
ratings.
