BZX84-C4V3,215

Single Zener Diodes Overview

The BZX84-C4V3,215 is a low-power voltage regulator diode from the Nexperia BZX84 series, housed in a small SOT23 (TO-236AB) Surface-Mounted Device plastic package. It features a nominal working voltage of 4.3 V with an approximate ±5 % tolerance range. The device supports a total power dissipation of up to 250 mW and operates within a junction temperature range of -55 °C to +150 °C. Key electrical characteristics include a maximum forward voltage of 0.9 V at 10 mA, a reverse current of 3 μA at VR = 4 V, and a differential resistance of 90 Ω at IZ = 5 mA.

Single Zener Diodes Feature Summary

• Low-power voltage regulation in a compact SOT23 surface-mount package
• Approximately ±5 % breakdown voltage tolerance for normalized E24 applications
• High non-repetitive peak reverse power dissipation capability

Single Zener Diodes Applications

• General regulation functions

Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required tolerance code 'C' for approximately ±5 % accuracy. Confirm the suffix ',215' corresponds to the standard reel packaging format intended for automated assembly processes. Ensure design compliance with the absolute maximum ratings provided in the official datasheet to prevent device stress or failure during operation.

Single Zener Diodes Selection Notes

Select this component when a stable reference voltage near 4.3 V is required in space-constrained designs. The SOT23 package facilitates efficient PCB layout for high-density circuitry. Consider the thermal resistance characteristics and ambient operating conditions to ensure the total power dissipation limit remains within safe boundaries during continuous operation.

Single Zener Diodes Part Context

This component belongs to the BZX84 series, which offers a comprehensive range of breakdown voltages from 2.4 V to 75 V. The series provides three distinct tolerance options: ±1 %, ±2 %, and approximately ±5 %. The BZX84-C4V3 specifically addresses applications requiring the mid-range voltage stability offered by the C-tolerance variant within the standardized E24 voltage series.

Single Zener Diodes Replacement Considerations

Compatible alternatives within the same family include BZX84-A4V3 and BZX84-B4V3, which offer tighter tolerances of ±1 % and ±2 % respectively. Other manufacturers may provide functionally equivalent Zener diodes in the SOT23 package, though pinout and thermal specifications should be verified against the original datasheet.
