Single Zener Diodes Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified suppliers. Confirm RoHS compliance status and check for recent Product Change Notifications (PCNs) regarding manufacturing changes. Ensure the specific tape-and-reel packaging matches assembly line requirements. Validate that the ±10% tolerance aligns with circuit design specifications before final procurement decisions.

Single Zener Diodes Selection Notes

Select this component when a 6.8V Zener voltage is required in an SMB surface-mount footprint. Consider the 2W power rating for thermal management needs. Compare against other SMBJ series variants if different voltage levels are needed. Ensure the operating temperature range meets environmental conditions. Verify compatibility with automated pick-and-place equipment due to the reel packaging format.

Single Zener Diodes Part Context

This part belongs to the SMBJ47xx series of Zener diodes from Microchip Technology. These devices are designed for general-purpose voltage regulation and clamping. The SMBJ4736 variant specifically targets the 6.8V market segment. The series offers robust performance in small surface-mount packages suitable for space-constrained designs.

Single Zener Diodes Replacement Considerations

Check for direct substitutes within the SMBJ4736 family or equivalent 6.8V Zener diodes in DO-214AA packages from other manufacturers. Verify pinout compatibility and thermal characteristics. Note that some related parts may be discontinued; consult official obsolescence notices.
