BZX84-C15/DG/B3,23

Single Zener Diodes Overview

The Nexperia BZX84-C15/DG/B3,23 is a low-power voltage regulator diode housed in a small SOT-23 (TO-236AB) surface-mounted plastic package. It provides a nominal Zener voltage of 15 V with an approximate ±5% tolerance range. The device features a total power dissipation of 250 mW and supports a non-repetitive peak reverse power dissipation of up to 40 W. Operating characteristics include a maximum forward voltage of 0.9 V at 10 mA, a junction temperature range from -55 °C to +150 °C, and a storage temperature range from -65 °C to +150 °C.

Single Zener Diodes Feature Summary

• Compact three-lead SOT-23 surface-mount package design
• Approximately ±5% breakdown voltage tolerance for general regulation
• High thermal stability with junction temperatures up to 150 °C

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix /DG/B3,23 against official Nexperia documentation to confirm tape-and-reel packaging details and marking codes. Ensure the component meets the required environmental standards for the intended application, as this series is not automotive qualified unless explicitly designated. Cross-reference the datasheet revision date to confirm current product status and any potential specification updates.

Single Zener Diodes Selection Notes

Select this component when a compact SOT-23 footprint is required for low-power voltage regulation tasks. The approximately ±5% tolerance makes it suitable for general-purpose applications where tight voltage precision is not critical. Consider the 250 mW power dissipation limit and thermal resistance values when designing heat management strategies for dense circuit layouts.

Single Zener Diodes Part Context

This part belongs to the Nexperia BZX84 series, which offers a comprehensive range of normalized E24 breakdown voltages from 2.4 V to 75 V. The series includes variants with ±1%, ±2%, and ±5% tolerances, providing flexibility for various design requirements. All devices share the same SOT-23 package and pinout configuration, facilitating easy substitution within designs requiring different voltage levels.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other BZX84-C15 variants from Nexperia or equivalent 15 V Zener diodes in SOT-23 packages from other manufacturers, provided they match the 250 mW power rating and electrical characteristics.
