Application Notes

Part Numbering System for PolyZen Devices

Definitions
VZ Zener clamping voltage measured at current IZt and 20°C.
IZT Test current at which VZ is measured.
IHOLD Maximum steady state IPTC that will not generate a trip event at the specified temperature. Ratings assume IFLT = 0A.
R Typ 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).
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.

Recommended reflow methods:

  • Hot air
  • Nitrogen

Recommendations:

  • Devices can be cleaned using standard methods and aqueous solvents.
  • Tyco Electronics believes that the optimum conditions for forming acceptable solder fillets occur when a reasonable amount of solder paste is placed underneath each solder pad. As such, Tyco Electronics requests that customers comply with our recommended solder pad layouts.
  • Tyco Electronics requests that customer board layouts refrain from placing raised features (e.g. vias, nomenclature, traces, etc.) underneath PolySwitch devices. It is possible that raised features could negatively impact solderability performance of our devices.
