JANTXV1N4622D-1

Single Zener Diodes Overview

The JANTXV1N4622D-1 is a hermetically sealed Zener diode manufactured by Microchip Technology. It features a DO-213AA (SMA) surface-mount package and operates within an extended temperature range of -65°C to +175°C. The device provides a nominal Zener voltage of 4.7 V with a tight tolerance of ±2%. Rated for 500 mW power dissipation, it utilizes a round-end voltage regulator design suitable for high-reliability applications requiring stable voltage reference in harsh environments.

Single Zener Diodes Procurement Notes

Verify the specific suffix '-1' indicates the internal metallurgical bond required for your application. Confirm that the DO-213AA footprint matches your PCB layout. Ensure the procurement channel sources directly from authorized distributors to guarantee authenticity and traceability for military-grade components.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed SMA package is mandatory. Compare against JAN1N4622D-1 if lower cost is acceptable without hermetic sealing. Verify that the 4.7 V nominal voltage aligns with circuit requirements. Check impedance specifications against load current variations to ensure stability.

Single Zener Diodes Part Context

This part belongs to the 1N4622 series of low noise Zener diodes produced by Microchip. The 'JANTXV' prefix denotes a specific quality level within the military grade lineup. The '-1' suffix specifies the hermetic seal variant. These devices are designed for critical applications where standard commercial parts would fail due to environmental stress.

Single Zener Diodes Replacement Considerations

Direct substitutes include JAN1N4622D-1 or JAN1N4622D depending on hermetic requirements. Cross-reference with other manufacturers' hermetically sealed SMA Zener diodes rated at 4.7 V. Ensure pinout compatibility and thermal characteristics match before substitution.
