TVS Diodes 1.5KE18A 1500W 18V Pack of 20 Chanzon Unidirectional

Description

Product Overview

The Chanzon 1.5KE18A TVS diode is engineered to provide high‑power transient voltage suppression for demanding industrial applications. With a rating of 1500 W and an 18 V working voltage, this unidirectional device clamps voltage spikes quickly, protecting downstream components from damage caused by electrostatic discharge (ESD) and other transient events. The diodes are lead‑free, RoHS‑compliant, and feature a through‑hole DO‑201AD (DO‑27) package that fits standard PCB layouts. Each pack contains 20 units, individually sealed in an ESD‑protected bag with a clear label indicating key specifications for easy identification and long‑term storage.

Usage

These TVS diodes are ideal for protecting power supplies, motor controllers, sensor interfaces, and communication lines in industrial equipment. They excel in environments where voltage transients are common, such as manufacturing lines, automation systems, and renewable energy installations. The 20‑piece pack offers flexibility for prototyping, small‑batch production, or as spare parts for maintenance inventories. Install the diode across the line you wish to protect, ensuring correct polarity for unidirectional operation, and you’ll achieve reliable ESD protection without compromising circuit performance.

FAQ

What does unidirectional mean for a TVS diode?

Unidirectional TVS diodes conduct in one direction, allowing normal forward voltage while clamping reverse voltage spikes. This makes them suitable for DC circuits where polarity is fixed.

Can I use these diodes in AC applications?

For AC circuits, a bidirectional TVS diode is recommended. However, if the AC voltage is within the diode’s reverse standoff rating and the circuit includes a rectifier, a unidirectional diode may be used with proper design considerations.

How do I identify the correct orientation when soldering?

The diode marking on the package indicates the cathode side. Align the cathode marking with the circuit’s polarity to ensure correct operation.

Are the diodes suitable for high‑frequency switching power supplies?

Yes, the fast response time of the 1.5KE18A model makes it effective for protecting high‑frequency switching regulators from transient events.

What is the warranty period for this product?

Chanzon offers a standard one‑year warranty covering manufacturing defects, backed by our technical support team for troubleshooting and replacement assistance.
