Application Notes

Part Numbering System for PolyZen Devices

Definitions
VZ Voltage out
IZT Current at which VZ is measured
IHOLD Maximum steady state IPTC that will not generate a trip event at the specified temperature. Specification assumes IFLT is sufficiently low so as to prevent the diode from acting as a heat source.
R Typ Resistance between VIN and VOUT pins during normal operation at room temperature
R1MAX The maximum resistance between VIN and VOUT pins during normal operation 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 diode portion of the device can withstand and remain resettable; testing is conducted at ±24V and -16V with no load connected to VOUT
VINT Max The voltage at which typical devices (98% devices , 95% confidence) survived at least 100 trip cycles and 24 hours trip endurance at the specified voltage and current (IPTC)

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.
