BZX384-C36 – NXP

Overview

The NXP BZX384-C36 is a precision low-power voltage regulator diode designed for stable reference voltage generation in compact electronic systems. Its primary function is to maintain a constant output voltage of 36V, crucial for biasing sensitive analog circuitry. A key design consideration often overlooked is the trade-off between its minimal quiescent current draw (≤300 mW total power dissipation) and its inherent dynamic impedance; achieving tighter regulation under varying load conditions necessitates careful selection of series resistance to mitigate voltage deviations, especially in high-impedance circuits.

Key Features

• Nominal Working Voltage: 36 V
• Total Power Dissipation: ≤ 300 mW
• Tolerance Series: Approximately ±5 %
• Working Voltage Range: 2.4 V to 75 V (E24 range)
• Non-repetitive Peak Reverse Power Dissipation: ≤ 40 W
• Package: SOD323 (SC-76) SMD

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 biasing for operational amplifiers in sensor conditioning circuits.
• Stable reference generation for analog-to-digital converters (ADCs) in measurement equipment.
