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.
