Single Zener Diodes Procurement Notes

Verify the specific suffix 'URE3' confirms the surface-mount DO-213AA package and lead-free composition. Confirm that the 'TR' designation indicates tape-and-reel packaging for automated insertion. Ensure compatibility with your assembly equipment regarding reel specifications. Cross-reference the manufacturer's latest datasheet to confirm any updates to mechanical dimensions or thermal characteristics before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 2.7V regulation point is required in a surface-mount form factor. Consider the ±5% tolerance for budgeting voltage accuracy in your design. Evaluate the 0.5W power dissipation limit against expected operating currents to ensure thermal safety. Compare dynamic impedance values if line regulation performance is critical for the application environment.

Single Zener Diodes Part Context

This part belongs to Microchip's family of single Zener diodes, often derived from traditional axial-leaded designs adapted for surface mount. The URE3 suffix typically denotes a specific tape-and-reel variant of the standard 1N4618 series. These devices are commonly used in consumer electronics and industrial control systems where small footprint and reliable voltage clamping are necessary.

Single Zener Diodes Replacement Considerations

Direct substitutes may include other 2.7V Zener diodes in SMA packages such as those from ON Semiconductor or Vishay. Verify pinout compatibility and power rating equivalence. For hermetic requirements, consider the 1N4618C-1 series if glass-sealed DO-35 packages are acceptable instead of surface mount.
