DESCRIPTION:
This Transient Voltage Suppressor is an economical, molded, commercial product
used to protect voltage sensitive components from destruction or partial degradation.
The response time of their clamping action is virtually instantaneous (1 x 10
-12
seconds) and they have a peak pulse power rating of 500 watts for 1 ms as depicted in
Figure 1 and 2. Microsemi also offers a great variety of other Transient Voltage
Suppressor's to meet higher and lower power demands and special applications.
