APPLICATION
This TVS is an economical, molded, commercial product voltage-
sensitive components from destruction or partial degradation. The
response time of their clamping action is virtually instantaneous(
1X10
-12
seconds) and they have a peak pulse power rating of 600
watts for 1 ms as depicted in Figure 1 and 2. MCC also offers
various varieties of TVS to meet higher and lower power demands
and special applications.
NOTES:Forward Voltage (Vf)@!50 amps peak, 8.3 msec sine
wave equal to 3.5 volts max. (For unidirectional only)
For Bidirectional Construction, indicate a C or CA suffix
after part number,i.e.P6KE440CA.
Capacitance will be 1/2 that shown in Figure 4.
