DESCRIPTION
These 1500 watt transient voltage suppressors offer power-handling
capabilities only found in larger packages. They are most often
used for protecting against transients from inductive switching
environments or induced secondary lightning effects as found in
lower surge levels of IEC61000-4-5. With very fast response times,
they are also effective in protection from ESD or EFT. Powermite®
package features include a full metallic bottom that eliminates the
possibility of solder-flux entrapment during assembly. They also
provide unique locking tab acting as an integral heat sink. With
its very short terminations, parasitic inductance is minimized to
reduce voltage overshoots during fast-rise-time transients.
