Single Zener Diodes Procurement Notes

Verify that the ordering suffix /TR confirms the tape and reel packaging format required for your assembly line. Confirm the JAN grade designation aligns with your specific reliability and radiation hardness requirements. Ensure the DO-35 package dimensions match your board space constraints. Cross-reference the manufacturer part number with official Microchip documentation to validate authenticity and current production status before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is required under extreme thermal conditions or potential radiation exposure. The ±1% tolerance makes it suitable for sensitive reference applications. Consider the through-hole mounting style if automated surface mount equipment is unavailable. Evaluate the 0.5 W power rating against expected circuit load currents to ensure safe operation within thermal limits during continuous duty cycles.

Single Zener Diodes Part Context

This part belongs to the JAN series of voltage regulator diodes, which are characterized by enhanced durability compared to commercial grades. The JAN prefix indicates qualification for military standards, ensuring consistent performance across wide environmental variations. This specific model represents a standardized Zener diode solution for critical infrastructure where component failure is not an option.

Single Zener Diodes Replacement Considerations

Direct substitutes include other JAN-series Zener diodes with identical 8.2 V ratings and DO-35 packages. Verify compatibility with equivalent impedance and power dissipation values. Alternative manufacturers may offer commercial equivalents, but these lack the specified radiation hardness and extended temperature range qualifications required for this application.
