Littelfuse ICTE-45/MPTE-45 Silicon avalanche diodes - 1500 watt axial leaded transient voltage suppressor Datasheet

Silicon Avalanche Diodes
1500 Watt Axial Leaded Transient Voltage Suppressors
ICTE/MPTE Series
®
The ICTE/MPTE series 1500 W transient suppressors are designed
specifically for protection of CMOS, NMOS, BiMOS, and other
integrated circuits available today for TTL, DTL, ECL, RTL, and
linear functions. This series offers the lowest clamping voltages.
