POLYZEN DEVICES
Polymer Protected Zener Diode
PolyZen devices are polymer-enhanced, precision Zener
diodes. They offer resettable protection against multi-Watt
fault events without the need for multi-Watt heat sinks.
The Zener diode used for voltage clamping a PolyZen
device was selected due to its relatively flat voltage
vs. current response. This helps improve output voltage
clamping, even when input voltage is high and diode
currents are large.
An advanced feature of the PolyZen device is that the
Zener diode is thermally coupled to a resistively non-
linear, PPTC (polymer positive temperature coefficient)
layer. This PPTC layer is fully integrated into the device
and is electrically in series between VIN and the diode
clamped VOUT.
This advanced PPTC layer responds to either extended
diode heating or overcurrent events by transitioning from a low to high resistance state, also known as “tripping.” A
tripped PPTC will limit current and generate voltage drop. It helps to protect both the Zener diode and the follow-on
electronics and effectively increases the diode’s power handling capability.
The polymer-enhanced Zener diode helps protect sensitive portable electronics from damage caused by inductive
voltage spikes, voltage transients, incorrect power supplies and reverse bias. These devices are particularly suitable for
portable electronics and other low-power DC devices.
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
• Halogen free
(refers to: Br≥900ppm, Cl≥900ppm, Br+Cl≥1500ppm)
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 helps minimize damage
from upstream inductive spikes
• Minimal power dissipation requirements
• Single component placement
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

Table PZ2 — Definition of Terms
VZ Zener clamping voltage measured at current IZT and 20°C.
IZT Test current at which VZ is measured.
IHOLD Maximum steady state current IPTC that will not generate a trip event at the specified temperature.
Ratings assume IFLT = 0A.
RTyp Typical resistance between VIN and VOUT pins when the device is at room temperature.
R1MAX The maximum resistance between VIN and VOUT pins, at room temperature, one hour after first trip or
after reflow soldering.
IFLT Current flowing through the Zener diode.
IFLT MAX Maximum RMS fault current the Zener diode component of the device can withstand and remain resettable;
testing is conducted at rated voltage with no load connected to VOUT
.
VINT MAX The voltage (VIN - VOUT “post trip”) at which typical qualification devices (98% devices, 95% confidence) survived
at least 100 trip cycles and 24 hours trip endurance when “tripped” at the specified voltage and current (IPTC).
IPTC Current flowing through the PPTC portion of the circuit.
IOUT Current flowing out the VOUT pin of the device.
Trip Event A condition where the PPTC transitions to a high resistance state, thereby limiting IPTC, and significantly
increasing the voltage drop between VIN and VOUT
.
