GENERAL DESCRIPTION
   Littelfuse PolyZen devices are polymer enhanced, precision Zener diode. 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
• Integrated protection on over current,
   over voltage, over temperature and ESD
• 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
