JAN1N5293-1

Current Regulation - Diodes, Transistors Overview

The JAN1N5293-1 is a current regulator diode manufactured by Microchip Technology, designed for through-hole mounting in the DO-7 (DO-204AA) axial leaded package. It provides a regulated current of 748 µA with a maximum voltage rating of 100 V and a power dissipation capacity of 475 mW. Qualified under MIL-PRF-19500/463, this component operates within a junction temperature range of -65°C to +175°C. The device functions as a constant current source over a broad voltage range, serving as a counterpart to Zener diodes which regulate voltage.

• Current limiting protection in sensitive electronic systems

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific suffix designation to confirm the exact military qualification level and testing standards required for your application. Ensure that the DO-7 package dimensions align with your PCB layout constraints. Confirm RoHS status if environmental compliance is mandatory for the end product. Cross-reference the manufacturer's latest datasheet for any recent parameter updates or assembly site notifications.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a precise current value near 748 µA is required without complex circuitry. Consider the 100 V maximum voltage rating to ensure it exceeds the expected voltage drop across the load. Evaluate the thermal environment to ensure the 475 mW power dissipation limit is not exceeded at the maximum operating temperature of 175°C.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the popular 1N5283-1 through 1N5314-1 series of 0.5 watt current regulators. These devices offer a selection of currents ranging from 0.22 mA to 4.7 mA in standard 10% tolerances. The series is designed to provide current regulation similar to how Zener diodes provide voltage regulation, but in a comparable axial-leaded package form factor.

Current Regulation - Diodes, Transistors Replacement Considerations

Compatible substitutes include other parts from the 1N5283-1 to 1N5314-1 series with matching current ratings. Verify that alternative components meet the same MIL-PRF-19500/463 qualification requirements if military grade performance is necessary.
