Overview
The PHILIPS BZX284-C33 is a 33V, 5% tolerance Zener diode designed for voltage regulation and transient suppression in compact electronic assemblies. Its 400mW power dissipation capability makes it suitable for moderate current applications, though designers must carefully consider its 40 Ohm dynamic impedance (Zzt) at the nominal Zener voltage, as this can impact the loop stability and ripple rejection in precision regulator circuits, especially under rapidly changing load conditions. This component, while now obsolete, represents a foundational element in many legacy designs requiring robust, cost-effective voltage clamping.
Key Features
- Zener Voltage (Vz): 33 V
- Tolerance: ±5%
- Maximum Power Dissipation: 400 mW
- Maximum Dynamic Impedance (Zzt): 40 Ohms
- Reverse Leakage @ Vr: 50 nA @ 23.1 V
- Package: SOD-110 (Surface Mount)
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.
- Precision voltage reference generation for low-power analog circuits
- Overvoltage protection for sensitive digital interfaces
- Shunt regulation in battery-powered portable devices
- Transient voltage suppression in signal conditioning paths
