1500 Watt Axial Leaded Transient Voltage Suppressors
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.
FEATURES
Stand-off voltage range 5 to 45 Volts
Uni-directional and Bi-directional
Glass passivated junction
Very low clamping voltages
100% surge tested
MAXIMUM RATING
Peak Pulse Power (Ppk): 1500 Watts (10 x 1000s) @25C
(see diagram on page 3 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: -55C to +150C
MECHANICAL CHARACTERISTICS
Case: DO-201AD: Molded plastic over glass
passivated junction
Terminals: Axial leads, solderable per MIL-STD-202
Method 208
Solderable leads = 230C for 10 seconds (1.59mm from case)
Marking: cathode band, (positive terminal, uni-directional
devices only), device code, logo
Weight: 1.5 grammes (approx)
Agency Approvals:
Recognized under the Components
Program of Underwriters Laboratories.
