JANTX1N747D-1/TR

Single Zener Diodes Overview

The JANTX1N747D-1/TR is a single silicon Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 3.6 V with a tight tolerance of ±1%. The device operates in the through-hole DO-35 (DO-204AH) axial package and dissipates up to 500 mW of power. Key electrical characteristics include a maximum reverse leakage current of 3 µA and a Zener impedance of 24 Ohms at the test current. It supports an extended operating temperature range from -65°C to +175°C, suitable for demanding environments.

Single Zener Diodes Procurement Notes

Verify the specific suffix 'JANTX' confirms the required MIL-PRF-19500/127 quality level and ±1% tolerance. Confirm the '/TR' designation indicates tape-and-reel packaging rather than bulk. Ensure the DO-35 package dimensions match your PCB footprint requirements. Cross-reference the manufacturer's latest datasheet for any updates on material compliance or testing standards before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V reference with superior accuracy compared to standard commercial grades is required. The JANTX grade offers tighter voltage tolerance and enhanced thermal stability compared to JAN or commercial variants. Consider the 500 mW power dissipation limit and derating curves for high-temperature operation. Verify that the axial DO-35 form factor fits the mechanical constraints of the assembly process.

Single Zener Diodes Part Context

This part belongs to the 1N747 series of Zener diodes, widely used in regulated power supplies and reference circuits. The JANTX designation signifies a screened version meeting specific military reliability standards. Microchip Technology continues production of these legacy parts to support long-term maintenance and defense applications where component obsolescence must be managed carefully.

Single Zener Diodes Replacement Considerations

Direct substitutes include JAN1N747D-1/TR for lower tolerance grades or JANTXV1N747D-1/TR for even tighter specifications. Commercial equivalents like 1N747A may be considered if MIL-spec requirements are not mandatory. Verify pinout compatibility and ensure thermal management strategies align with the 500 mW dissipation rating of the replacement.
