Thermal Characteristics
(TA = 25 °C unless otherwise noted)
Application
• This series of Silicon Transient Suppressors is
used in applications where large voltage tran-
sients 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 watts for one millisec-
ond. The response time of TVS diode clamping
action is effectively instantaneous (1 x 10-9 sec-
onds bidirectional); therefore, they can protect
integrated circuits, MOS devices, hybrids, and
other voltage sensitive semiconductors and com-
ponents. TVS diodes can also be used in series or
parallel to increase the peak power ratings.
