VOLTAGE SUPPRESSORS
DESCRIPTION
Microsemi’s new Powermite UPT series transient voltage suppressors
feature oxide-passivated chips, with high-temperature solder bonds for high
surge capability, and negligible electrical degradation under repeated surge
conditions.
In addition to its size advantages, Powermite package includes a full
metallic bottom that eliminates the possibility of solder flux entrapment at
assembly and a unique locking tab serving as an integral heat sink.
Innovative design makes this device fully compatible for use with
automatic insertion equipment.
