PZU5.6DB2,115

Overview

The PZU5.6DB2,115 is a dual independent Zener diode array manufactured by Nexperia USA Inc., housed in a compact 5-TSSOP (SC-70-5) surface-mount package. It features a nominal Zener voltage of 5.6 V with a tight tolerance of ±2%, ensuring precise voltage regulation for sensitive circuits. The device supports a maximum power dissipation of 250 mW and operates within an extended temperature range from -55 °C to +150 °C. Key electrical characteristics include a reverse leakage current of 5 µA at 1 V and a forward voltage of 900 mV at 10 mA. This component is designed for high-density circuit designs requiring reliable over-voltage protection and stable reference voltages.

Feature Summary

• Dual independent Zener configuration for multi-channel voltage regulation
• Tight ±2% voltage tolerance for precision applications
• Compact 5-TSSOP footprint suitable for space-constrained designs

Applications

• General voltage regulation and reference functions
• Over-voltage protection in dense circuit boards
• Signal line clamping in consumer electronics

Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official Nexperia documentation to ensure compatibility. Confirm availability status as product lifecycles may change. Cross-reference pinout configurations with the official datasheet before integration into existing PCB layouts to prevent design errors.

Selection Notes

Select this component when dual independent Zener protection is required in a minimal footprint. The ±2% tolerance makes it suitable for precision analog circuits where standard 5% or 10% tolerances are insufficient. Ensure the thermal management strategy accounts for the 250 mW power dissipation limit in the SOT-353 package under worst-case operating conditions.

Part Context

This device belongs to the PZU series of Zener diode arrays from Nexperia, which offers various voltage options and package types. The DB2 suffix indicates the specific 5-TSSOP packaging variant. It complements single Zener diodes like the PZU13BA by providing dual functionality in a smaller area, ideal for modern miniaturized electronic devices.

Replacement Considerations

Direct replacements must match the 5-TSSOP package, 5.6 V nominal voltage, and ±2% tolerance. Verify that alternative manufacturers offer equivalent power dissipation ratings and leakage current specifications to maintain circuit performance without redesign.
