The STMicroelectronics STEF12SPUR is an electronic fuse designed to protect a 12 V line, rated for a continuous output current of 3.5 A. Its input voltage range of 10 V to 13.8 V covers the nominal 12 V supply with margin for transients, while the -40°C to 125°C junction temperature rating suits it for industrial and automotive environments where the ambient temperature inside the enclosure can climb well above 85°C.
It is an electronic fuse for a 12 V line, providing overcurrent protection with a 3.5 A continuous output rating. It replaces a traditional fuse or PTC in applications where fast, resettable protection is needed.
The STEF12PUR has a similar 3.6 A output and the same package type, but its input voltage range is 7.6 V versus the STEF12SPUR's 10 V to 13.8 V.
