Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix /TR indicates tape and reel packaging configuration against official Microchip documentation. Confirm MIL-PRF-19500/463 compliance status directly with the manufacturer or authorized distributors. Ensure the DO-7 package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a precise 1.98 mA constant current is required within a 100 V operational window. Consider the 475 mW power dissipation limit to ensure thermal management sufficiency. Verify that the -55°C to +175°C temperature range aligns with the intended environmental operating conditions for the application design.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5283-1 through 1N5314-1 series of 0.5 W current regulators produced by Microchip/Microsemi. These devices serve as counterparts to Zener diodes by regulating current over a broad voltage range rather than voltage over a broad current range. The series offers various current values in standard tolerances within similar axial-leaded packages.

Current Regulation - Diodes, Transistors Replacement Considerations

Check for direct equivalents within the 1N5304 series from other qualified manufacturers. Verify that substitute parts maintain the 1.98 mA nominal current and 100 V peak voltage ratings. Ensure any replacement also meets the MIL-PRF-19500/463 military qualification if required for the specific system integrity.
