Note 2: This device is intended for limited fault protection. Repeated trip events or extended trip endurance can degrade the device and may affect performance to specifications. Performance impact will depend on multiple factors including, but not limited to, voltage, trip current, trip duration, trip cycles, and circuit design. For details or ratings specific to your application contact TE Connectivity Circuit Protection directly. Note 3: Specifications developed using 1.0 ounce 0.045” wide copper traces on dedicated FR4 test boards. Performance in your application may vary. Note 4: I is the current at which V is measured (V = V ). Additional V values are available on request. zt z Z OUT Z Note 5: I : Maximum steady state I (current entering or exiting the V pin of the device) that will not generate a trip event at the HOLD PTC IN specified temperature. Specification assumes I (current flowing through the Zener diode) is sufficiently low so as to prevent FLT the diode from acting as a heat source. Testing is conducted with an “open” Zener. Note 6: R Typ: Resistance between V and V pins during normal operation at room temperature. IN OUT Note 7: R : The maximum resistance between V and V pins at room temperature, one hour after 1st trip or after reflow 1Max IN OUT soldering. Note 8: V Max: V Max relates to the voltage across the PPTC portion of the PolyZen device (V -V ). V Max is defined as the INT INT IN OUT INT voltage (V -V ) at which typical qualification devices (98% devices, 95% confidence) survived at least 100 trip cycles and IN OUT 24 hours trip endurance at the specified voltage (V -V ) and current (I ). V Max testing is conducted using a "shorted" IN OUT PTC INT load (V = 0 V). V Max is a survivability rating, not a performance rating. OUT INT Note 9: I Max: I Max relates to the stead state current flowing through the diode portion of the PolyZen device in a fault condition, FLT FLT prior to a trip event. I Max is defined as the current at which typical qualification devices (12 parts per lot from 3 lots) survived FLT 100 test cycles. RMS fault currents above I Max may permanently damage the diode portion of the PolyZen device. Testing FLT is conducted with NO load connected to V , such that I = 0. “Test voltage” is defined as the voltage between V to GND OUT OUT IN and includes the PolyZen Diode drop. Specification is dependent on the direction of current flow through the diode. I Max is a FLT survivability rating, not a performance rating. Note 10: The power dissipated by the device when in the “tripped” state, as measured on TE test boards (see note 3). Note 11: Specifications based on limited qualification data and subject to change.
