GENERAL DESCRIPTION
   Littelfuse PolyZen devices are polymer enhanced, precision Zener diode microassemblies. They offer resettable protection against multi-Watt fault events without the need for multi-Watt heat sinks.

FEATURES
• Overvoltage transient suppression
• Stable VZ vs fault current
• Time delayed, overvoltage trip
• Time delayed, reverse bias trip
• Multi-Watt power handling
   capability
• Integrated device construction
• RoHS Compliant

BenefitS
• Stable Zener diode helps shield
   downstream electronics from
   overvoltage and reverse bias
• Trip events shut out overvoltage
   and reverse bias sources
• Analog nature of trip events
   minimizes upstream inductive
   spikes
• Minimal power dissipation
   requirements
• Single component placement

TARGET APPLICATIONS
• DC power port protection in
   portable electronics
• DC power port protection for
   systems using barrel jacks for
   power input
• Internal overvoltage & transient
   suppression
• DC output voltage regulation
