Single Zener Diodes Procurement Notes

Verify the specific suffix TR13 to confirm the tape and reel packaging format required for automated assembly processes. Ensure compatibility with standard SMB footprint dimensions during PCB layout. Confirm that the 6.2 V rating aligns with the target circuit's regulatory requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a surface-mount solution is preferred over through-hole alternatives for space-constrained designs. The 200 W peak pulse capability makes it suitable for environments with potential electrical noise or surges. Consider the DO-214AA package size relative to available board real estate.

Single Zener Diodes Part Context

This part belongs to the SMBJ series of silicon Zener diodes from Microchip Technology. These devices are characterized by their robust construction and ability to operate effectively in demanding conditions. The series offers various voltage options within a standardized surface-mount form factor.

Single Zener Diodes Replacement Considerations

Direct substitutes include other SMBJ4735A variants from different manufacturers that meet the same DO-214AA footprint and 6.2 V specification. Verify pinout compatibility and thermal characteristics when considering cross-brand replacements.
