DESCRIPTION:
This Transient Voltage Suppressor is an economical, molded, commercial product
used to protect voltage sensitive components from destruction or partial degradation.
-12
The response time of their clamping action is virtually instantaneous (1 x 10
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.
