ICTE/MPTE series
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.
FEATURES
Stand-off voltage Range 5 to 45 Volts
Glass Passivated Junction
Very low clamping voltages
Uni-directional and Bi-directional
100% Surge tested
MAXIMUM RATING
Peak Pulse Power (Ppk): 1500 Watts (10 X 1000s)
(see diagram on page 6 for wave form)
5 Watt Steady State
Response time: 1 X 10-12 seconds (theoretical)
Forward surge rating: 200 Amps, 8.3ms half sine wave, (uni-directional devices only)
Operating & storage temperature: -55°C to +150°C
MECHANICAL CHARACTERISTICS
Case: DO-201AD; moulded plastic over glass passivated junction
Terminals: Axial leads, solderable per MIL-STD-202 Method 208
Solderable leads = 230°C for 10 seconds (1.59mm from case)
Marking: cathode band (positive terminal, uni-directional devices only), device code, logo
Weight: 1.5 grammes (approx)
