Description and Introduction

BZX585 series; Voltage regulator diodes The **BZX585-B43** from NXP Semiconductors is a high-performance Zener diode designed for precision voltage regulation and protection in electronic circuits. With a nominal breakdown voltage of **43V**, this component ensures stable voltage clamping, making it ideal for applications requiring reliable overvoltage protection or voltage reference.  

Featuring a **500mW power dissipation rating**, the BZX585-B43 offers robust performance in a compact SOD-523 (SC-79) surface-mount package, suitable for space-constrained designs. Its low leakage current and sharp breakdown characteristics enhance efficiency in circuits where precise voltage control is critical.  

Engineers frequently utilize this Zener diode in power supplies, voltage regulators, and transient suppression circuits. Its consistent performance across a wide temperature range ensures reliability in industrial, automotive, and consumer electronics applications.  

Key specifications include a **±5% tolerance** on the breakdown voltage, ensuring tight regulation, and a **low dynamic impedance** for improved stability under varying load conditions. The BZX585-B43 is RoHS compliant, meeting modern environmental standards.  

For designers seeking a dependable voltage reference or protection component, the BZX585-B43 provides a balance of precision, durability, and compact form factor, making it a versatile choice for modern electronic systems.
