Low Profile 1500 Watt

Transient Voltage Suppressor

SCOTTSD A L E DIVISION

3PMT5.0A thru 3PMT170A

DESCRIPTION

APPEARANCE

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

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

.
