MICROCHIP UPT17E3/TR13

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.

• 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 (UPT8Re3 thru UPT48Re3)
  • Bidirectional (UPTB5e3 thru UPTB48e3)
• 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.
• RoHS compliant versions available.

• Protects sensitive components such as IC’s, CMOS, Bipolar, BiCMOS, ECL, DTL, T L, etc.
• Protection from switching and induced RF transients.
• Secondary lightning protection per IEC61000 - 4 - 5 with 42 Ohms source impedance:
  • Class 1: UPT5//UPT5R/UPTB8 to17
  • Class 2: UPT5//UPT5R/UPTB5 to12
