DESCRIPTION
APPEARANCE
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. Both unidirectional and bidirectional configurations are available.
In addition to its size advantages, Powermite package includes a full
metallic bottom (cathode) that eliminates possibility of solder flux entrapment
at assembly and a unique locking tab serving as an integral heat sink.
DO-216AA
Innovative design makes this device fully compatible for use with automatic
insertion equipment.
