(Pack of 100 Pieces) Chanzon BZX55C4V3 (1N5229B) Zener Diode 0.5W 4.3V DO-35 (DO-204AH) Axial Diodes 0.5 Watt 4.3 Volt

Description

Product Overview

The Chanzon BZX55C4V3 is a precision Zener diode designed for reliable voltage reference and regulation in a wide range of electronic applications. Constructed with a lead‑free, RoHS‑compliant silicon crystal, the device delivers a stable 0.5 W power dissipation capability and a tightly controlled 4.3 V breakdown voltage. Its DO‑35 (DO‑204AH) axial package provides a compact footprint while maintaining excellent thermal performance, making it suitable for both through‑hole PCB assembly and prototyping breadboards. Each diode is individually tested to guarantee low reverse leakage and high reverse‑bias stability, ensuring consistent operation even under fluctuating temperature conditions. The pack of 100 pieces is sealed in an anti‑static ESD bag with a clear label that lists the key specifications, offering long‑term protection against moisture, dust, and electrostatic discharge.

Usage

These Zener diodes excel in applications that require precise voltage clamping, such as power supply regulation, battery charging circuits, and over‑voltage protection for sensitive semiconductor devices. Their low reverse current characteristic makes them ideal for low‑noise analog front‑ends, sensor biasing, and reference voltage generation in instrumentation amplifiers. Hobbyists and makers will find the axial lead form factor easy to insert into prototype boards, while professional engineers can rely on the tight tolerance for high‑reliability designs in automotive, industrial, and communication equipment. The 100‑piece quantity ensures you have ample spares for large production runs, field repairs, or educational labs where component turnover is high.

FAQ

What is the maximum current this Zener diode can handle?

The BZX55C4V3 is rated for a continuous forward current of 0.5 A, which corresponds to its 0.5 W power dissipation rating at the specified breakdown voltage.

Can these diodes be used in high‑temperature environments?

Yes. The silicon crystal and axial package are designed to operate reliably from –55 °C up to +150 °C, making them suitable for automotive and industrial applications where temperature extremes are common.

Are the diodes suitable for surface‑mount technology (SMT) assembly?

These particular units are supplied in a through‑hole DO‑35 package, which is not intended for SMT. However, they can be used on SMT boards with appropriate lead‑through holes or adapters.

How do I identify the correct orientation when soldering?

The cathode end is marked with a white band on the diode body. Align this band with the circuit’s negative side to ensure proper polarity during soldering.

What warranty or guarantee does Chanzon provide?

Chanzon offers a one‑year limited warranty covering manufacturing defects. If a diode fails due to a defect, we will replace it at no additional cost, provided the issue is reported within the warranty period.
