Single Zener Diodes Procurement Notes

Verify the specific qualification level (JAN, JANTX, JANTXV, or JANS) required for your application, as availability varies by grade. Confirm RoHS compliance status if applicable, noting that commercial versions may differ from military qualifications. Ensure the TR suffix indicates tape and reel packaging when ordering. Cross-reference datasheet electrical limits against your system's thermal and current requirements before procurement.

Single Zener Diodes Selection Notes

Select this component for applications requiring strict voltage regulation under extreme temperatures and radiation exposure. The DO-35 axial lead format facilitates through-hole mounting. Consider the 5% standard tolerance unless tighter specifications are needed. Evaluate the maximum reverse current and dynamic impedance parameters to ensure compatibility with your circuit's sensitivity requirements.

Single Zener Diodes Part Context

This part belongs to the 1N4099-1 through 1N4135-1 series of 500 mW metallurgically bonded glass Zener diodes manufactured by Microsemi (now Microchip). These devices are JEDEC registered and designed for high-reliability applications. The series covers a wide voltage range from 1.8V to 100V, providing versatile options for various regulation needs in industrial and military sectors.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other 1N4115 variants from different manufacturers meeting MIL-PRF-19500/435 standards. Verify pinout compatibility and package dimensions (DO-35) for direct replacement. Ensure equivalent electrical parameters such as Zener voltage, impedance, and power dissipation are matched to maintain circuit performance.
