UPTB33E3/TR7 Microchip

UPT5e3 UPT48e3, UPT8Re3 UPT48Re3 and UPTB5e3 UPTB48e3 5V 48V Small Footprint, Surface Mount Available Transient Voltage Suppressors DESCRIPTION Microsemis unique and 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.
