• Withstands high surge stresses and exhibits minimal voltage change versus current.
• Features a gull-wing design allowing for visible solder connections in the DO-215AA package.

Single Zener Diodes Applications

• Voltage regulation in high-density circuit designs.
• Low-profile mounting applications requiring robust surge handling.
• Circuits requiring non-sensitive ESD performance per MIL-STD-750 method 1020.

Single Zener Diodes Procurement Notes

Verify component authenticity through authorized channels due to potential supply chain variations. Confirm RoHS compliance status via specific ordering suffixes, as standard versions may differ. Check datasheet revisions for updates on thermal resistance values and maximum ratings. Ensure compatibility with existing footprint layouts for the DO-215AA package before integration.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 5-watt surface mount Zener solution. The 'A' suffix indicates a plus/minus 10% voltage tolerance. Consider the DO-215AA gull-wing package for visibility during assembly. Evaluate thermal management requirements against the specified junction-to-ambient resistance when designing PCB layouts.

Single Zener Diodes Part Context

This part belongs to the SMBG5333B-5388B series of 5-watt Zener diodes. The series covers breakdown voltages from 3.3V to 200V with various tolerance options.
