PZU2.7DB2,115

Overview

The PZU2.7DB2,115 is a dual isolated general-purpose Zener diode from the Nexperia PZUxDB2 series, housed in a SOT353 (SC-88A) surface-mounted package. It features two independent diodes within a single compact component. The nominal working voltage is 2.7 V with a tolerance of approximately ±2%. Key electrical parameters include a maximum reverse current of 100 μA at IZ = 0.5 mA and a differential resistance of 1000 Ω at IZ = 5 mA. The device supports a total power dissipation of up to 250 mW at ambient temperatures ≤ 25 °C and operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Dual isolated diode configuration for space-efficient circuit design
• Halogen-free plastic package suitable for surface-mounted applications
• AEC-Q101 qualified for automotive reliability standards

Applications

• General regulation functions

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as tape and reel specifications. Confirm that the component status remains active or check longevity program notices for potential obsolescence warnings before finalizing procurement plans.

Selection Notes

Select this component when a dual Zener solution is required in a minimal footprint. Ensure the 2.7 V nominal voltage aligns with circuit requirements. Verify thermal management capabilities given the 250 mW total power dissipation limit in the SOT353 package.

Part Context

This part belongs to the PZUxDB2 series, which offers a wide range of nominal voltages from 2.7 V to 24 V. All variants share the same SOT353 package and dual isolated architecture, allowing for consistent board layout across different voltage reference designs.

Replacement Considerations

Direct substitutes within the same series include other PZUxDB2 types with different voltage ratings but identical packages. Cross-brand replacements require matching the dual isolated topology, SOT353 footprint, and ±2% tolerance.
