PZU4.7DB2,115

Overview

The Nexperia PZU4.7DB2,115 is a dual isolated general-purpose Zener diode housed in an SOT353 (SC-88A) surface-mounted package. It features two independent diodes within a single five-lead component. The nominal working voltage is 4.7 V with a tolerance of approximately ±2%. Key electrical parameters include a total power dissipation of 250 mW at 25 °C and a non-repetitive peak reverse power dissipation of 40 W. The device operates within a junction temperature range of -55 °C to +150 °C and is qualified according to the AEC-Q101 standard for automotive applications.

Feature Summary

• Dual isolated diode configuration allows independent operation within a compact footprint.
• Halogen-free plastic package suitable for surface-mounted design.
• Qualified for automotive applications under AEC-Q101 standards.

Applications

• General regulation functions
• Automotive electronic circuits

Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package variant and manufacturing origin. Confirm product status as active or obsolete before finalizing procurement plans. Ensure compliance with RoHS directives and halogen-free requirements specified for the DG variant if applicable. Cross-reference marking codes to validate authenticity upon receipt.

Selection Notes

Select this component when space-constrained designs require two independent Zener references in a single SOT353 package. The ±2% tolerance series provides tighter voltage accuracy compared to standard ±5% types. Consider the 250 mW total power dissipation limit for thermal management in dense PCB layouts. Verify that the 4.7 V nominal voltage aligns with the target circuit regulation requirements.

Part Context

This part belongs to the PZUxDB2 series, which offers a wide working voltage range from 2.7 V to 24 V. The series utilizes the SOT353 package to minimize board area while maintaining robust performance characteristics. It serves as a compact solution for voltage reference and protection tasks in modern electronics where component count reduction is critical.

Replacement Considerations

Direct replacements must match the SOT353 pinout and dual isolated configuration. Verify equivalent voltage tolerance and power dissipation ratings. Check for AEC-Q101 qualification if the application requires automotive reliability standards. Ensure thermal resistance characteristics are compatible with the existing PCB footprint.
