Description

These 3PMT170A 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, 3PMT170A 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. 3PMT170A 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.
