Single Zener Diodes Procurement Notes

Verify the specific manufacturer origin, as the datasheet identifies Microsemi Scottsdale Division while the model prefix indicates Microchip Technology. Confirm RoHS compliance status associated with the e3 suffix and ensure the TR8 tape and reel packaging matches the required handling specifications for automated assembly processes.

Single Zener Diodes Selection Notes

Select this component when a robust 5-watt axial Zener diode is required for high-power applications. The A suffix denotes a standard 10% voltage tolerance suitable for general-purpose regulation. Ensure adequate heat sinking is provided to maintain performance within the specified thermal resistance limits during continuous operation.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series covers a wide voltage selection from 3.3V to 200V. The e3 suffix indicates RoHS compliant devices with annealed matte-tin plating on the terminals, meeting environmental standards for modern electronics manufacturing.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available in the SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B series. Verify that the replacement maintains the same 5-watt power rating and voltage tolerance requirements.
