(Pack of 20 Pieces) Chanzon TVS Diodes 1.5KE150CA 1500W 150V DO-201AD (DO-27) Bidirectional Channel 1500 Watt 150 Volt

Description

Product Overview

The Chanzon 1.5KE150CA TVS diode is engineered to provide high‑performance transient voltage suppression in demanding industrial environments. Rated for 1500 watts of surge energy and a clamping voltage of 150 volts, each diode offers a robust barrier against voltage spikes that can damage sensitive components. The device is a bidirectional, through‑hole component, allowing it to protect both polarities of a circuit with a single part, simplifying board layout and reducing part count. Constructed from lead‑free, RoHS‑compliant materials, the diode meets strict environmental standards while delivering reliable, long‑lasting performance. Packaged in a protective ESD bag with a clear label, the 20‑piece set ensures easy identification and inventory management for engineers and technicians. Dimensions of 6.69 × 5.12 × 0.59 inches and a lightweight 1.09 oz per unit make the diodes easy to handle during assembly, and the DO‑201AD (DO‑27) package provides a proven footprint for a wide range of applications.

Usage

These TVS diodes are ideally suited for protecting power supplies, motor drive circuits, and communication interfaces in industrial equipment, renewable energy systems, and automotive electronics. Their high surge current capability makes them effective in environments where lightning strikes, inductive load switching, or electrostatic discharge events are common. Install the diodes across the power lines of a circuit to clamp transient voltages, preventing them from reaching downstream components such as microcontrollers, sensors, and semiconductor devices. The bidirectional nature of the 1.5KE150CA allows it to safeguard both the positive and negative rails of a dual‑supply system, making it a versatile choice for DC‑DC converters, inverters, and battery management modules. Because the component is through‑hole, it offers strong mechanical anchoring, which is beneficial in applications that experience vibration or shock, such as industrial machinery, robotics, and outdoor installations.

FAQ

What does bidirectional mean for a TVS diode?

Bidirectional TVS diodes can clamp voltage spikes of either polarity, meaning they protect both the positive and negative sides of a circuit. This is especially useful in DC power lines where transients can appear as either positive or negative spikes, allowing a single component to replace two unidirectional devices.

Can these diodes be used in automotive applications?

Yes, the 1.5KE150CA’s high surge rating and rugged through‑hole package make it suitable for automotive environments. It can protect electronic control units, sensor interfaces, and power distribution modules from inductive load switching and lightning‑induced transients commonly encountered in vehicles.

How do I handle the diodes during PCB assembly?

Because the diodes are through‑hole components, they are inserted into pre‑drilled holes on the PCB and soldered from the opposite side. This method provides a strong mechanical bond, which is advantageous in applications subject to vibration. Ensure the ESD bag is opened in a static‑controlled area and handle the diodes by the leads to avoid contaminating the semiconductor surface.

What is the typical response time of the 1.5KE150CA?

The device reacts to voltage transients within a few nanoseconds, effectively clamping the surge before it can propagate through the circuit. This rapid response is critical for protecting high‑speed digital components and sensitive analog front ends.

Is there a warranty or guarantee for these diodes?

Chanzon offers a standard limited warranty covering manufacturing defects for a period of one year from the date of purchase. Should any unit fail under normal operating conditions within this timeframe, we will provide a replacement or refund, subject to verification of the failure mode.
