SCOTTSDALE DIVISION
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 entrapm ent 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
.
