(Pack of 20 Pieces) Chanzon TVS Diodes 1.5KE440A 1.5KE440 1500W 440V DO-201AD (DO-27) Unidirectional Channel 1500 Watt 440 Volt

Description

Product Overview

The Chanzon 1.5KE440A TVS diode is engineered to provide high‑performance transient voltage suppression for demanding industrial applications. With a rated power dissipation of 1500 watts and a stand‑off voltage of 440 volts, this component can absorb large voltage spikes caused by electrostatic discharge, inductive load switching, or lightning surges. Housed in the widely used DO‑201AD (DO‑27) through‑hole package, the diode occupies minimal board space while delivering reliable protection. The device is lead‑free and RoHS compliant, meeting modern environmental standards. Each unit is supplied in a dedicated ESD bag with a clear label indicating its key specifications, ensuring easy identification and long‑term storage without degradation. The pack contains 20 identical diodes, making it an economical choice for manufacturers who need to protect multiple circuits or build inventory for future production runs.

Usage

These TVS diodes are suited for a broad range of industrial and scientific equipment where voltage transients can compromise performance or cause catastrophic failure. Typical use cases include power supplies, motor control circuits, data acquisition systems, and communication interfaces that operate in harsh environments. The unidirectional design is ideal for protecting DC‑biased circuits, while the high power rating allows the diode to clamp severe spikes without being damaged. Installation is straightforward: the through‑hole leads fit standard PCB footprints, and the component can be soldered using conventional reflow or wave soldering processes. Because the diodes are supplied in a 20‑piece ESD‑protected bag, they are ready for batch assembly lines, reducing handling time and minimizing the risk of accidental damage during manufacturing. Engineers often select this part when designing equipment that must meet stringent reliability standards, such as aerospace, automotive, and heavy‑industry applications.

FAQ

What is the difference between unidirectional and bidirectional TVS diodes?

Unidirectional TVS diodes are designed to protect circuits with a DC bias, allowing current flow in one direction while clamping voltage spikes in the opposite direction. Bidirectional diodes, on the other hand, protect AC‑biased or dual‑polarity circuits by clamping voltage spikes in both directions. The 1.5KE440A is a unidirectional device, making it ideal for DC‑powered systems where reverse polarity protection is not required.

Can the 1.5KE440A be used in high‑frequency applications?

Yes, the diode’s low capacitance and fast response time make it suitable for high‑frequency environments. It can effectively suppress fast transients without introducing significant signal distortion, which is essential for communication and data‑transfer circuits that operate at MHz frequencies.

How should the diode be mounted to achieve optimal performance?

For best results, mount the diode using a standard through‑hole technique on a clean, flat PCB surface. Ensure that the solder joints are solid and that the leads are trimmed to the appropriate length to avoid mechanical stress. Proper grounding of the PCB and adherence to recommended layout guidelines will further enhance the diode’s protective capabilities.

Is the 20‑piece pack suitable for prototyping as well as production?

Absolutely. The 20‑piece ESD‑bagged pack provides enough units for prototype testing, allowing engineers to evaluate performance before committing to larger orders. Once the design is validated, the same pack can be used to populate small‑scale production runs, offering flexibility and cost efficiency.

What warranty or guarantee does Chanzon provide for this TVS diode?

Chanzon offers a standard limited warranty that covers manufacturing defects for a period of one year from the date of purchase. If a diode fails due to a defect, the company will replace the unit at no additional cost, provided the failure is not caused by improper handling or installation.
