Single Zener Diodes Procurement Notes

Verify the specific suffix CUS to confirm the E-MELF surface mount package variant. Ensure compatibility with existing PCB footprints and soldering profiles. Confirm that the military grade qualification meets project requirements. Check for RoHS compliance status as indicated by manufacturer documentation. Validate availability through authorized distributors due to potential long lead times associated with specialized components.

Single Zener Diodes Selection Notes

Select this component when a 160 V Zener diode with strict ±2% tolerance is required in a surface mount format. The E-MELF package suits space-constrained designs needing robust performance. Consider the 5 W power rating for thermal management needs. Evaluate the low leakage current specification for sensitive circuit applications. Compare against other military-grade options if alternative packages are preferred.

Single Zener Diodes Part Context

This part belongs to the JANTXV series of Zener diodes from Microchip Technology, formerly Microsemi. The series is known for providing radiation-hardened and high-reliability semiconductor solutions. These components are typically used in critical systems where standard commercial parts would fail. The JANTXV designation indicates enhanced testing and screening procedures beyond standard industrial grades.

Single Zener Diodes Replacement Considerations

Direct substitutes may include other JANTXV1N4987 variants with different package styles such as JANTXV1N4987US for surface mount or JANTXV1N4987C for through-hole. Verify pinout and mechanical dimensions before substitution. Ensure equivalent electrical parameters including voltage, power, and tolerance are maintained.
