Zener Diode Chanzon BZX55C18 0.5W 18V Pack of 100 Axial DO-35

Description

Product Overview

The Chanzon BZX55C18 Zener diode is engineered to provide precise voltage regulation at 18 volts while handling a modest power dissipation of 0.5 watts. Housed in the industry‑standard DO‑35 (DO‑204AH) axial package, this component offers a compact footprint that fits easily onto traditional through‑hole PCBs. The diode’s construction follows lead‑free, RoHS‑compliant standards, ensuring it meets modern environmental regulations while delivering reliable performance. Each unit exhibits a very sharp reverse characteristic, meaning the reverse leakage current remains exceptionally low across the operating range, which translates to higher circuit stability and reduced noise. The part is supplied in a pack of 100 pieces, each individually protected within an ESD‑safe bag that bears a clear label of the main specifications, guaranteeing long‑term protection against static discharge and easy identification during inventory management. The product dimensions of the packaging are modest, measuring 6.69 x 5.12 x 0.59 inches and weighing only 0.85 ounces, making it convenient for both small‑scale hobbyist kits and larger industrial stockpiles. Since its introduction on February 3, 2018, the BZX55C18 has earned a solid reputation, reflected in a 4.4‑star rating from verified customers and a best‑seller rank that places it among the top Zener diodes on major e‑commerce platforms. This combination of technical specifications, quality assurance, and market acceptance makes the Chanzon BZX55C18 a dependable choice for a wide range of electronic designs.

Usage

The BZX55C18 is ideally suited for applications that require stable voltage reference points, such as power supply regulation, voltage clamping, and protection circuits. Its 18‑volt breakdown voltage makes it a perfect candidate for protecting sensitive downstream components from voltage spikes in automotive, industrial, and consumer electronics environments. Designers often employ this diode in voltage‑divider networks, biasing circuits for transistors, and as a reference element in analog‑to‑digital converter (ADC) calibration stages. Because of its low reverse leakage, the diode maintains accuracy even in high‑temperature conditions, which is essential for devices operating in harsh environments like outdoor sensor nodes or automotive control units. The axial lead style simplifies soldering onto both prototype boards and production‑grade printed circuit boards, allowing for quick assembly and reliable mechanical anchoring. The 100‑piece ESD‑protected packaging ensures that engineers and hobbyists alike can keep a ready supply on hand for iterative design cycles, batch production runs, or repair kits. Whether you are building a hobbyist Arduino shield, a professional power‑management module, or a custom instrumentation amplifier, the Chanzon BZX55C18 provides the stability and durability required for long‑term operation.
