1N5313-1 Microchip

1N5283-1 thru 1N5314-1 Qualified Levels: CURRENT REGULATOR DIODES JAN, JANTX, JANTXV Available on Qualified per MIL-PRF-19500/463 and JANS commercial versions DESCRIPTION The popular 1N5283-1 thru 1N5314-1 series of 0.5 watt current regulators provides a selection from 0.22 mA to 4.7 mA in standard 10% tolerances. These devices regulate current over a broad voltage range as a counter part offering to Zeners (that regulate voltage over a broad current range) in similar size axial-leaded packages. The somewhat larger DO-7 packaging option offers a double-plug internal bond connection with a larger active die element for its unique function as a current limiter. Microsemi also offers numerous other Zener products to meet higher and lower power voltage regulation applications.
