Hold current and trip characteristics
The 0ZCJ0050FF2G is a polymeric PTC resettable fuse with a hold current (Ih) of 500 mA max and a trip current (It) of 1 A, meaning normal circuit current must stay below 500 mA to avoid tripping, and the device will switch to high resistance when current reaches 1 A. Time to trip is 100 ms, so the fuse responds quickly to overcurrent faults, limiting energy let-through to downstream components.
Voltage and fault ratings
Rated for a maximum voltage of 8 V and a maximum fault current of 100 A — the part can safely interrupt a short circuit up to that level without rupturing. Initial resistance (Ri) is 150 mOhms min, rising to 700 mOhms max after tripping (R1); this post-trip resistance limits the leakage current once the fault clears, but also adds a voltage drop that must be accounted for in the load budget.
Automotive qualification and approvals
Additional approvals include cURus and TUV, confirming compliance with North American and European safety standards for overcurrent protection devices.
Package and board integration
Operating temperature range is -40°C to 85°C, covering the industrial and automotive ambient envelope without derating.
