NCP3712ASNT1G

NCP3712ASN, SZNCP3712ASN Over Voltage Protected High Side Switch This switch is primarily intended to protect loads from transients by isolating the load from the transient energy rather than absorbing it.

Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1.
