Transient Voltage Suppressors
DESCRIPTION
Microsemi’s unique Powermite UPT series of 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, the Powermite package includes a
fully metallic bottom (cathode) side that eliminates the possibility of solder flux entrapment at
assembly and a unique locking tab serves as an integral heat sink. Its innovative design makes this
device fully compatible for use with automatic insertion equipment.
