Single Zener Diodes Procurement Notes

Verify the specific suffix D/TR against official Microchip documentation to confirm the exact reel quantity and tape-and-reel specifications. Ensure the procurement channel provides valid traceability data for this part number. Confirm that the delivered components match the specified DO-213AA package dimensions and lead finish requirements.

Single Zener Diodes Selection Notes

Select this component when a low-voltage Zener reference is required in a surface-mount design. The 1600 ohm impedance suggests suitability for low-current applications. Verify that the 500 mW power rating aligns with the thermal management capabilities of the target PCB layout under expected operating conditions.

Single Zener Diodes Part Context

This part belongs to the standard Zener diode family manufactured by Microchip Technology. It shares core electrical parameters with through-hole variants like the 1N4619 but utilizes a surface-mount form factor. The designation indicates a specific packaging configuration intended for automated assembly processes.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 3 V Zener diodes in the DO-213AA package with comparable impedance and leakage specifications. Cross-reference with industry-standard equivalents such as BZX55C3V0 or similar SMD packages if pinout compatibility allows.
