JAN1N5306-1

Current Regulation - Diodes, Transistors Overview

The JAN1N5306-1 is a current regulator diode manufactured by Microchip Technology, designed for through-hole mounting in the DO-7 (DO-204AH) axial package. It provides a regulated current of 2.2 mA with a maximum limiting voltage of 1.95 V and a peak operating voltage of 100 V. The device dissipates up to 500 mW and operates within a temperature range of -65°C to +175°C. Qualified per MIL-PRF-19500/463, it serves as a counterpart to Zener diodes by regulating current over a broad voltage range.

Current Regulation - Diodes, Transistors Procurement Notes

Verify the specific qualification level required for your application, as the JAN series meets MIL-PRF-19500/463 standards. Confirm that the DO-7 package and lead configuration match your PCB layout constraints. Ensure the thermal management plan accommodates the 500 mW power dissipation at the maximum operating temperature of 175°C. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Current Regulation - Diodes, Transistors Selection Notes

Select this component when a stable current source is needed independent of voltage fluctuations. Compare the 2.2 mA regulation point against circuit requirements to ensure compatibility with downstream components. Consider the 100 V breakdown voltage as the upper limit for the voltage drop across the device. Evaluate the DO-7 package size relative to available board space compared to surface mount alternatives like the UR series.

Current Regulation - Diodes, Transistors Part Context

This part belongs to the 1N5283-1 through 1N5314-1 series of 0.5 watt current regulators. The series offers various current values from 0.22 mA to 4.7 mA. The JAN suffix indicates military qualification under MIL-PRF-19500/463, distinguishing it from commercial versions which may lack rigorous environmental testing.

Current Regulation - Diodes, Transistors Replacement Considerations

Equivalent parts include JANTX1N5306-1 and JANTXV1N5306-1, which share the same electrical specifications but differ in qualification levels. Commercial variants such as 1N5306-1 are also functionally similar but lack military certification.
