Product Details:
Overview
The Diotec Semiconductor BZX84C4V3 is a highly stable 4.3V Zener diode designed for precise voltage regulation in compact SOT-23 packages. Its critical operational characteristic is maintaining a consistent 4.3V reference, even under varying current loads, with a tight 5% tolerance. A key design consideration for engineers is its 300mW power dissipation limit; exceeding this can lead to thermal runaway, necessitating careful thermal management in high-current applications, a common trade-off in miniature SMT components.
Key Features
- Zener Voltage (Vz): 4.3 V
- Power Dissipation (Pd): 300 mW
- Voltage Tolerance: ±5%
- Maximum Reverse Leakage Current (Ir): 3 µA
- Zener Impedance (Zz): 90 Ohms
- Package: SOT-23 (2.9mm x 1.3mm x 1.1mm)
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 referencing in battery-operated devices
- Signal clamping in sensitive analog input stages
- Voltage stabilization for microcontroller power rails
- Protection against transient overvoltages in consumer electronics
