• Capable of handling high peak pulse power dissipation of 600 W for transient protection.
• Designed for surface mount integration using the standard DO-214AA (SMB) footprint.
• Operates reliably across an extended industrial temperature range from -65°C to +150°C.

Single Zener Diodes Applications

• General purpose voltage regulation in electronic circuits
• Transient voltage suppression in signal lines
• Protection against electrostatic discharge events

Single Zener Diodes Procurement Notes

Verify the specific suffix E3 confirms RoHS3 compliance before procurement. Confirm the TR13 designation indicates tape and reel packaging suitable for automated assembly processes. Ensure the DO-214AA package dimensions match the target PCB layout requirements. Check for any recent product change notifications regarding manufacturing origin or material composition updates.

Single Zener Diodes Selection Notes

Select this component when a 16 V regulation point is required in a compact surface mount form factor. The 2 W power rating supports higher energy dissipation compared to smaller packages like SMA. Consider the ±10% tolerance if tighter voltage precision is not critical. Verify that the 600 W peak pulse capability meets the expected transient energy levels in the application environment.

Single Zener Diodes Part Context

This part belongs to the SMBJ series of Zener diodes from Microchip Technology, which are optimized for surface mount technology. The series offers various voltage options within the DO-214AA package, providing a balance between power handling and board space efficiency. The E3 suffix denotes environmental compliance, while TR13 specifies the bulk packaging format for high-volume production lines.

Single Zener Diodes Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 16 V Zener voltage, 2 W power rating, DO-214AA package, and ±10% tolerance specifications exactly.
