BZX284-B9V1,115

Single Zener Diodes Overview

The BZX284-B9V1,115 is a low-power voltage regulator diode from the NXP BZX284 series, housed in a very small ceramic SMD SOD110 package. It provides a nominal working voltage of 9.1 V with a tolerance of ±2%. The device supports a maximum total power dissipation of 400 mW and operates within a junction temperature range up to 150 °C. Key electrical characteristics include a differential resistance of 20 Ω (max) at an IZtest of 5 mA, a typical temperature coefficient of 5.5 mV/K, and a non-repetitive peak reverse current capability of 3.0 A.

Single Zener Diodes Feature Summary

• Low-power voltage regulation in a compact ceramic surface-mount package
• High-precision voltage tolerance for stable reference applications
• Robust thermal performance with defined junction-to-ambient resistance

Single Zener Diodes Applications

• General voltage regulation functions
• Voltage reference circuits
• Overvoltage protection stages

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel quantity configuration. Confirm that the component status remains active for new designs by consulting the latest NXP product availability data. Ensure the selected package variant aligns with the intended PCB footprint and soldering process requirements.

Single Zener Diodes Selection Notes

Select this component when precise voltage referencing is required in space-constrained designs. The ±2% tolerance offers tighter accuracy than standard Zener diodes. Consider the thermal resistance limits and ensure adequate board copper area for heat dissipation during continuous operation near maximum power ratings.

Single Zener Diodes Part Context

This part belongs to the BZX284 series of voltage regulator diodes manufactured by NXP Semiconductors. The series includes various voltage options ranging from 2.4 V to 75 V, available in both ±2% and ±5% tolerance variants. All devices share the same SOD110 ceramic package form factor.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 9.1 V nominal voltage, ±2% tolerance, and SOD110 package. Verify equivalent power dissipation and thermal resistance specifications to ensure compatibility with existing circuit constraints.
