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