Current Regulation - Diodes, Transistors Part Context

This component belongs to the 1N5283-1 through 1N5314-1 series of 0.5-watt current regulators. These devices serve as counterparts to Zener diodes by regulating current over a broad voltage range rather than voltage over a current range. The series offers standard 10% current tolerances and is available in various military qualification levels including JAN, JANTX, JANTXV, and JANS.

Current Regulation - Diodes, Transistors Replacement Considerations

Verify that the replacement part maintains the JANS qualification level and MIL-PRF-19500/463 compliance. Ensure the substitute matches the 264 µA regulation current, 100 V maximum voltage, and DO-7 package dimensions. Confirm thermal performance aligns with the original -55°C to +175°C operating range.
