Product Description

PolyZen Devices Polymer Protected Zener Diode

Product Overview
PolyZen devices are advanced polymer-enhanced Zener diodes designed to provide resettable protection against multi-Watt fault events without the need for external heat sinks. They offer stable voltage clamping with a relatively flat voltage vs. current response, ensuring reliable output voltage regulation even under high input voltage and large diode currents. The integrated, resistively non-linear PPTC (polymer positive temperature coefficient) layer responds to extended diode heating or overcurrent events by transitioning to a high resistance state, effectively limiting current and protecting both the Zener diode and downstream electronics. These devices are ideal for protecting sensitive portable electronics and other low-power DC devices from inductive voltage spikes, voltage transients, incorrect power supplies, and reverse bias.

Key Benefits:

  • Stable Zener diode shields downstream electronics from overvoltage and reverse bias.
  • Trip events effectively shut out overvoltage and reverse bias sources.
  • Analog nature of trip events minimizes damage from upstream inductive spikes.
  • Minimal power dissipation requirements.
  • Single component placement for integrated protection.

Applications:

  • DC power port protection in portable electronics.
  • DC power port protection for systems using barrel jacks for power input.
  • Internal overvoltage and transient suppression.
  • DC output voltage regulation.
  • Tablet PCs and portable electronics.
