PZU84-B15R

Single Zener Diodes Overview

The Nexperia PZU84-B15R is a Zener voltage regulator diode housed in an SOT23 surface-mounted device plastic package. It provides a nominal working voltage of 15 V with a ±2% tolerance series. The device features a total power dissipation of 250 mW and a non-repetitive peak reverse power dissipation of 40 W. Key electrical characteristics include a maximum forward voltage of 0.9 V at 10 mA, a differential resistance of 11 Ω at IZ = 5 mA, and a reverse current of 11 μA maximum at IZ = 5 mA.

Single Zener Diodes Feature Summary

• Designed for general regulation functions within a wide working voltage range from 2.4 V to 51 V.
• Offers two tolerance series: ±2% and approximately ±5% for precise voltage control.
• Features very low dynamic impedances at low currents and hard breakdown knee characteristics for voltages up to 10 V.
• Includes intentional minor rise of leakage current for optimized fast switching and noise reduction for higher voltage types.

• General regulation functions

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix 'R' against the manufacturer's official documentation to confirm reel packaging specifications. Ensure the component matches the SOT23 package outline dimensions and pin configuration (Anode-NC-Cathode) required by the target circuit design. Cross-reference the marking code '%RY' for quality assurance during incoming inspection.

Single Zener Diodes Selection Notes

Select this component when a tight ±2% voltage tolerance is required for a 15 V reference point. Consider the 250 mW power dissipation limit and thermal resistance values for heat management in dense PCB layouts. Evaluate the differential resistance and capacitance parameters to ensure compatibility with the intended signal frequency and load conditions.

Single Zener Diodes Part Context

This part belongs to the Nexperia PZU84 series of general-purpose Zener diodes. The series utilizes a small SOT23 leadless Surface-Mounted Device plastic package suitable for automated assembly. The lineup covers nominal working voltages from 2.4 V to 51 V, offering flexibility for various low-power voltage regulation and protection applications in consumer and industrial electronics.

Single Zener Diodes Replacement Considerations

Direct substitutes within the same series include other PZU84 variants with matching voltage and tolerance ratings, such as PZU84-B16 or PZU84-B14, provided the package and electrical characteristics align with the design requirements.
