DESCRIPTION

Microsemi’s unique and new Powermite MUPT 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 (anode) side that eliminates the possibility of solder flux entrapment at

assembly and a unique locking tab design serves as an integral heat sink. Its innovative design

makes this device fully compatible for use with automatic insertion equipment.

FEATURES

? Powermite package with standoff voltages 5 to 48 V.

? Both unidirectional and bidirectional polarities:

-Anode to case bottom (MUPT5e3 thru MUPT48e3)

-Bidirectional (MUPTB5e3 thru MUPTB48e3)

? Clamping time less than 100 pico-seconds for unidirectional and 5 nano-seconds for bidirectional.

? 100 surge current testing of all parts.

? Moisture classification is Level 1 with no dry pack required per IPC/JEDEC J-STD-020B.

? Both RoHS and non-RoHS compliant versions available.

APPLICATIONS / BENEFITS

? Protects sensitive components such as IC’s, CMOS, Bipolar, BiCMOS, ECL, DTL, T

2

L, etc.
