PZU3.6DB2,115

Overview

The PZU3.6DB2,115 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 five-lead component. The nominal working voltage is 3.6 V with a tolerance of approximately ±2%. Key electrical parameters include a total power dissipation of 250 mW and a non-repetitive peak reverse power dissipation of 40 W. The device operates within an ambient temperature range of -55 °C to +150 °C and is qualified according to AEC-Q101 standards 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.
• Wide working voltage range available across the series.

Applications

• General regulation functions
• Voltage reference circuits
• Over-voltage protection

Procurement Notes

Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details and manufacturing origin. Ensure compatibility with the required SOT353 footprint during PCB layout. Confirm that the selected variant meets all environmental and reliability requirements for the intended deployment environment before finalizing procurement.

Selection Notes

Select this component when dual isolated Zener regulation is required in space-constrained designs. The SOT353 package offers a small standard plastic form factor. Consider the ±2% tolerance series B2 for precise voltage referencing. Verify thermal management capabilities given the 250 mW total power dissipation limit at elevated temperatures.

Part Context

This part belongs to the PZUXDB2 series of dual Zener diodes manufactured by Nexperia. The series provides various nominal voltages ranging from 2.7 V to 24 V in the same SOT353 package. The 'B2' designation indicates the specific voltage tolerance class, while the ',115' suffix typically denotes tape and reel packaging for automated assembly processes.

Replacement Considerations

Direct replacements must match the SOT353 package, dual isolated configuration, and 3.6 V nominal voltage. Verify that any substitute component meets or exceeds the 250 mW power dissipation and AEC-Q101 qualification if automotive use is required. Pinout compatibility should be confirmed as pin 2 is not connected in the original device.
