APPLICATIONS
This TVS series is a low cost, 500 watt commercial and industrial product for use in applications where space is a premium and
where large voltage transients can permanently damage voltage-sensitive components.
The response time of TVS clamping action is 1.0ns for uni-directional and 5.0ns for bi-directional; therefore, they can protect
integrated circuits, MOS devices, hybrids, and other voltage-sensitive semiconductor components.
