SURFACE MOUNT TRANSIENT
VOLTAGE SUPPRESSORS
DESCRIPTION
Microsemi’s new 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. Microsemi also offers numerous other
products to meet higher and lower power voltage regulation applications.
