1N5283-1 thru 1N5314-1 CURRENT REGULATOR DIODES Available on commercial versions Qualified per MIL-PRF-19500/463 Qualified Levels: JAN, JANTX, JANTXV and JANS 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. DO-7 Package Important: For the latest information, visit our website http://www.microsemi.com. FEATURES • • • • • • JEDEC registered 1N5283 thru 1N5314. High source impedance.
