POWERMITE®
Low Profile 1500 Watt
Transient Voltage Suppressor
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.
