• Over-voltage protection in military-grade electronic equipment
• Voltage regulation in harsh environment industrial control units

Single Zener Diodes Procurement Notes

Verify the specific suffix US indicates surface mount or axial configuration as per official datasheets, noting potential confusion with similar part numbers. Confirm MIL-PRF-19500 compliance if military qualification is required. Check for RoHS exemption status as these components often fall under restricted substance exemptions. Ensure the ordering quantity matches the manufacturer's standard packaging requirements for this specific variant.

Single Zener Diodes Selection Notes

Select this component when a 33 V regulated supply is needed in space-constrained or high-reliability designs. Compare against JAN1N4970 variants if through-hole mounting is preferred over surface mount. Consider the 5 W power rating to ensure adequate thermal management. Verify that the ±5% tolerance meets the circuit's voltage accuracy requirements compared to tighter tolerance alternatives.

Single Zener Diodes Part Context

This part belongs to the 1N497x series of Zener diodes produced by Microchip Technology (formerly Microsemi). The series offers various voltage ratings from 33 V to 75 V with consistent 5 W power handling capabilities. The JANTXV prefix denotes a specific quality and screening level within the company's military and aerospace product portfolio, ensuring enhanced reliability standards.

Single Zener Diodes Replacement Considerations

JAN1N4970US serves as a direct functional substitute with potentially different screening levels. JANTX1N4970US offers similar electrical characteristics with alternative quality assurance protocols. Verify pinout compatibility and thermal performance before substituting any variant within the 1N497x family.
