Single Zener Diodes Procurement Notes

Verify the specific suffix TR8 indicates tape and reel packaging configuration. Confirm RoHS compliance status as standard variants may differ. Ensure the supplier provides official Microsemi documentation to validate the part number authenticity and manufacturing origin before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V regulated supply is required with high thermal stability. The DO-41 package suits through-hole designs, while the reel packaging supports high-volume automated assembly. Verify that the 1 W power rating meets the thermal dissipation needs of the target application environment.

Single Zener Diodes Part Context

This component belongs to the JEDEC registered 1N4729A series of Zener diodes. The 'P' prefix typically denotes a plastic DO-41 package variant, while 'TR8' specifies the reel packaging format. This series is widely used for general-purpose voltage regulation tasks requiring moderate power handling capabilities.

Single Zener Diodes Replacement Considerations

Compatible substitutes include Vishay 1N4729A-TR and MCC 1N4729A-TP, which share identical electrical specifications and DO-41 packaging. Cross-reference datasheets to ensure equivalent impedance and leakage current characteristics match the original design requirements.
