Nexperia 1.43 V General Purpose Zener Diode 365 mW Surface Mount 2-Pin DFN1006BD-2 BZX884S-B43-QYL

Nexperia BZX884S-B43-QYL is a general purpose zener diode designed for voltage regulation applications requiring precise voltage control. It features a nominal zener voltage of 43 V with a tight tolerance of ±2%, making it suitable for circuits requiring stable voltage references. The diode is housed in a highly compact DFN1006BD-2 surface mount package with 2 pins, allowing for space-saving PCB layouts.

This diode supports a maximum power dissipation of 365 milliwatts, ensuring robust performance under typical electronic load conditions. Operating over a wide temperature range from -55°C to +150°C, the device is well-suited for harsh environmental and automotive applications, backed by AEC-Q101 qualification for automotive standards compliance.

Key electrical characteristics include a maximum max zener impedance of 375 ohms, a low maximum reverse leakage current of 50 nA, and a test current of 5 mA for zener voltage stability. The typical voltage temperature coefficient of 37.6 mV/K supports reliable operation across temperature variations.

The physical size of 1 mm length and 0.47 mm height facilitates integration in compact electronic designs. The single diode chip configuration offers straightforward voltage regulation functionality in discrete semiconductor applications.

Industrial use cases include power and signal conditioning in automotive electronics, industrial controls, telecommunications, and consumer electronic circuits requiring voltage stabilization and transient voltage suppression.
