Single Zener Diodes Procurement Notes

Verify that the component matches the specific JEDEC registration number and suffix requirements for your design. Confirm the RoHS compliant status and tape-and-reel packaging specifications align with your assembly process. Ensure adequate heat sinking is planned, as the device relies on thermal management to sustain its maximum DC current ratings during operation.

Single Zener Diodes Selection Notes

Select this component when a 5.6 V Zener voltage with ±10% tolerance is required. Consider the T-18 axial lead package for through-hole mounting applications. Evaluate the thermal resistance characteristics to ensure proper heat sinking is implemented. Verify that the moisture sensitivity level meets the storage and handling constraints of your manufacturing environment.

Single Zener Diodes Part Context

This part belongs to the Microsemi 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 to 200 volts with various tolerance options identified by suffix letters. These devices are designed for robust performance in demanding environments, featuring low thermal resistance and high surge current capabilities.

Single Zener Diodes Replacement Considerations

Equivalent parts within the same series include 1N5339B or 1N5339C depending on the required tolerance. Surface mount equivalents such as SMBJ5339B or SMBG5339B are available if board space is limited. Verify that any substitute maintains the same power dissipation rating and package dimensions.
