DESCRIPTION
APPEARANCE
The ICTE-5 through ICTE-45C series of Transient Voltage
Suppressors (TVSs) are designed for the protection of integrated
circuits that require very low Clamping Voltages (VC) during a
transient threat. Due to their very fast response time, protection
level and high Peak Pulse Power (PPP) capability, they are extremely
effective in providing protection against line transients generated by:
voltage reversals, capacitive or inductive load switching,
electromechanical switching, electrostatic discharge and
electromagnetic coupling.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
FEATURES
APPLICATIONS / BENEFITS
•
•
This series of TVS devices is designed to protect
Bipolar, MOS and Schottky improved integrated
circuits.
•
These transient voltage suppressors are
designed for the protection of integrated
circuits. Characterized by a very low
clamping voltage together with a low standoff
voltage, they afford a high degree of
protection to: TTL, ECL, DTL, MOS, CMOS,
VMOS, HMOS, NMOS and static memory
circuits.
Transient protection for CMOS, MOS, Bipolar,
ICS (TTL, ECL, DTL, RTL and linear functions)
•

NOTE 1: TVSs are normally selected according to the reverse “Stand Off Voltage” (VWM) which should be equal to or greater than the dc or continuous
peak operating voltage level.
* The minimum breakdown voltage as shown takes into consideration the +1 volt tolerance normally specified for power supply regulation on
most integrated circuit manufacturers data sheets. Similar devices are available with reduced clamping voltages where tighter regulated
power supply voltages are employed.
