ICTE/MPTE SERIES (1500 WATT) AXIAL TRANSIENT VOLTAGE SUPPRESSORS
The ICTE/MPTE series 1500 W transient suppressors are designed specifically for protection of
CMOS, NMOS, BiMOS, and other intergrated circuits available today for TTL, DTL, ECL, RTL,
and linear functions. This series offers the lowest clamping voltages.
