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.

FEATURES
• Powermite package with standoff voltages 5 to 48 V.
• Both unidirectional and bidirectional polarities:
-Anode to case bottom (UPT5e3 thru UPT48e3)
-Cathode to case bottom (UPT5Re3 thru UPT48Re3)
-Bidirectional (UPTB5e3 thru UPTB48e3)
• Clamping time less than 100 pico-seconds for unidirectional and 5 nano-secon ds for bidir ectional.

• Moisture classification is Level 1 with no dry pack required per IPC/JEDEC J-STD-020B.
• RoHS compliant versions available.
APPLICATIONS / BENEFITS
• Protects sensitive components such as IC’s, CMOS, Bipolar, BiCMOS, ECL, DTL, T2L, etc.
• Protect ion from switch ing and i nduc ed RF transients.
• New improved lower leakage current for the UPT5Re3:
-Integral heat sink / locking tabs
-Fully metallic bottom side eliminates flux entrapment
• Compliant to IEC6 1000-4-2 and IEC610 00-4-4 for ESD and EFT protection respectively.
• Secondary lightning protection per IEC61000-4-5 with 42 Ohms source impedance:
Class 1: UPT5//UPT5R/UPTB8 to17
Class 2: UPT5//UPT5R/UPTB5 to12
