Series features low voltage drops and fast trip times while offering full resettability.
The SMD0805, with the industry s smallest footprint, measuring only 2.2mm by 1.5mm, features four hold current ratings from 100mA to 500mA with a current interruption capability of 40A at rated voltage. All ratings offered comply with the UL 1950 Information Technology Equipment standard which requires that the maximum current available to the connector must be limited to 8 Amps in less than 60 seconds. The misconnection of 5 Volt and 12 Volt power lines between a disk drive and host computer can cause reverse polarity or inrush faults which may lead to failure of the disk drive capacitors. The SMD1812 prevents this fault condition by latching into it s high resistance state until the connections can be properly installed. Hold current ratings are available up to 2.6 Amps with very quick trip times - as low as 150ms.
