Overview

The onsemi BZX84C3V3 is a precision 3.3V Zener diode designed for robust voltage regulation in compact SOT-23 packages. Its critical operational characteristic is the tight 5% voltage tolerance, ensuring stable reference voltages essential for sensitive analog circuits. A key design consideration when implementing this device is managing its 350 mW power dissipation; exceeding this limit, especially under continuous high current conditions, can lead to thermal runaway and premature failure, necessitating careful heatsinking or duty cycle limitation.

Key Features

Zener Voltage (Vz): 3.3 V
Power Dissipation (Pd): 350 mW
Voltage Tolerance: ±5%
Maximum Reverse Leakage Current (Ir): 5 µA @ 1V
Zener Impedance (Zz): 95 Ohms @ 5 mA
Package: SOT-23 (2.92 mm x 1.3 mm x 0.93 mm)

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

Low-power voltage reference for battery-operated devices
Clamping and surge protection in sensitive signal paths
Voltage bias for active components in audio amplifiers
Power supply rail regulation in portable instrumentation
