Single Zener Diodes Procurement Notes

Verify the specific ordering suffixes to confirm RoHS compliance status and tape & reel packaging configuration. Ensure the selected variant matches the required voltage tolerance and terminal plating finish for your assembly process. Confirm availability as product lifecycles may change.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 68 V reference or regulation point with a 5-watt power dissipation capability. The DO-215AA gull-wing package facilitates visible solder connections. Consider thermal resistance values when designing heat sinking solutions for sustained operation.

Single Zener Diodes Part Context

This part belongs to the SMBG5333B through SMBG5388B series of surface mount silicon Zener diodes. These devices are electrically equivalent to the JEDEC registered 1N5333 through 1N5388 series. The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options.

Single Zener Diodes Replacement Considerations

The SMBJ5373A/TR13 is functionally equivalent to the standard axial-leaded 1N5373B diode regarding electrical characteristics. Verify pinout compatibility and physical footprint differences when substituting between the SMBG surface mount package and traditional axial packages.
