Polymer protected, precision zener diodes: The PolyZen device is a thermally protected, precision zener diode that helps protect circuits from overvoltage and overcurrent fault conditions.

Benefits:

• Helps shield downstream electronics from overvoltage and reverse bias
• Trip events shut out overvoltage and reverse bias sources
• Analog nature of trip events minimize upstream inductive spikes
• Helps reduce design costs with single component placement and minimal heat sinking requirements

Features:

• Overvoltage transient suppression
• Stable V_Z vs fault current
• Time delayed, overvoltage trip
• Time delayed, reverse bias trip
• Power handling on the order of 100 watt
• Integrated device construction
• RoHS compliant

Applications:

• Hard disk drive protection
• Computer subsystems
• Automotive electronics
• USB port protection
• Portable electronics
