Technical details

Electronic fuse with 8V to 48V input and 4A continuous rating

It protects downstream circuitry from overcurrent and overvoltage faults across an 8V to 48V input range, delivering up to 4A continuous output. The current-limit accuracy is held to ±5%, and the junction temperature range spans -40°C to 125°C, suiting it for industrial motor drives, automotive power distribution, battery-management systems, and telecom supplies where a resettable, semiconductor-based protection device replaces a traditional fuse or PTC.
