Single Zener Diodes Procurement Notes

Verify the specific suffix 'A' indicates a 5% voltage tolerance, as standard versions without the suffix typically carry a 10% tolerance. Confirm that the 'TP' suffix designates a RoHS-compliant lead-free finish. Ensure procurement from authorized distributors to guarantee genuine parts and full traceability.

Single Zener Diodes Selection Notes

Select this component for applications requiring precise voltage reference stability due to its sharp knee characteristics. Consider the 1W power dissipation capability and the wide operating temperature range when designing for harsh environments. Verify thermal resistance limits against ambient conditions.

Single Zener Diodes Part Context

This part belongs to the DL4728 through DL4761 series of 1 Watt Zener Diodes. The series covers a voltage range from 3.3V to 75V in the GLASS MELF case. These diodes are silicon planar devices designed for high-reliability applications.
