Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official Microchip Technology documentation to confirm tolerance and packaging details. Ensure the component matches the required DO-214AC footprint and thermal characteristics for your design. Cross-reference the datasheet electrical parameters to validate suitability for your circuit's voltage and power dissipation requirements.

Single Zener Diodes Selection Notes

Select this component when a 91V Zener reference is needed in a compact surface-mount form factor. The 5% tolerance provides standard precision for general regulation tasks. Consider the 2W steady-state power dissipation limit and thermal resistance when designing the PCB copper pad layout to ensure reliable operation under maximum load conditions.

Single Zener Diodes Part Context

This part belongs to the SMAJ4728A through SMAJ4764A series of 2-watt Zener diodes manufactured by Microchip Technology. The series covers a voltage range from 3.3V to 100V in the DO-214AC package. These devices are designed as surface-mount replacements for traditional axial leaded equivalents.

Single Zener Diodes Replacement Considerations

The SMAJ4763AE3/TR13 is electrically equivalent to the JEDEC registered 1N4763A. When substituting, verify that the replacement component supports the same 91V Zener voltage, 2W power rating, and DO-214AC package dimensions.
