SIP25M Semiconductor IC protector Description The SIP25M is IC Protectors have a very reliable current cut-off capability that protects Ics and their circuits from accidental short circuit loads. Whether operated in AC-DC circuits, these IC Protectors have a very low internal resistance in normal operation, but safely and rapidly break the circuit when the current cutoff level is exceeded. Features • • • • Cutoff is sharp and repeatable. Low internal resistance and minimal voltage drop. Good temperature characteristics. Withstands surges well. • Incombustible • Compact. • Rated for continuous use. Application IC surge protection. Operation notes Do not use this product on the primary side of commercial power supplies. Arcs that result after cutoff may damage the molding. Ordering Information Type NO.
