A new standard in voltage regulation – the BZX84 series

The BZX84 is a classic Zener diode in a compact SMD package, designed for voltage regulation and protection of electronic circuits against overvoltage. The series covers a wide range of Zener voltages – from 2.7 V to 22 V – allowing precise selection to meet specific design requirements. Low power dissipation, fast response to voltage changes, and stable voltage in the reverse direction make BZX84 diodes a reliable solution for analog, digital, and professional industrial systems. As an official distributor, we offer only original BZX84 diodes, guaranteeing high quality, full compliance with the manufacturer’s technical documentation, and stable availability.

It is also worth noting that in recent years, the semiconductor market has faced occasional component shortages and supply chain pressures. In this context, cooperation with reputable manufacturers and distributors is especially important. The challenges related to component availability, including NXP/Nexperia products, are discussed in detail in the article:
