5KP30A DIODE TVS 30V 5KW Uni‑Dir ESD Suppressor by Rizees Through‑Hole

Description

Product Overview

The 5KP30A DIODE TVS from Rizees is engineered as a high‑performance, uni‑directional transient voltage suppressor specifically crafted for demanding industrial environments. Featuring a reverse standoff voltage of 30 V and a breakdown voltage of 33.3 V, the device reliably clamps voltage spikes while maintaining a low capacitance profile for rapid response times. Its robust 5 kW power rating enables it to absorb and dissipate substantial surge energy, protecting downstream components from damage caused by electrostatic discharge (ESD) and transient over‑voltage events. Constructed for through‑hole mounting, the diode integrates seamlessly onto printed circuit boards, offering a secure mechanical connection and excellent thermal conductivity. The package’s compact footprint and durable lead‑frame design provide long‑term reliability, even under continuous high‑stress conditions typical of power supplies, motor drives, and control circuitry. Rizees, a recognized manufacturer in the ESD protection market, ensures each unit meets stringent quality standards, delivering consistent performance across a wide temperature range.

Usage

Designed for a broad spectrum of industrial applications, the 5KP30A DIODE TVS excels in protecting sensitive electronics within power conversion systems, inverter modules, and motor control units. Its through‑hole form factor makes it ideal for both new designs and retrofits, allowing engineers to replace older protection components without redesigning board layouts. The diode’s high power handling capability is particularly valuable in environments where large transient currents are common, such as automotive manufacturing lines, renewable energy installations, and heavy‑duty machinery. By limiting voltage excursions to safe levels, the device helps extend the lifespan of critical components, reduce downtime, and maintain system reliability. Installation is straightforward: the leads are soldered directly onto the PCB, and the component can be positioned close to vulnerable circuitry to maximize protection efficiency. The 5KP30A is also suitable for use in test equipment, laboratory instrumentation, and any scenario where precise voltage clamping is required to safeguard delicate measurement electronics.

FAQ

What is the difference between uni‑directional and bi‑directional TVS diodes?

Uni‑directional TVS diodes conduct in one direction, providing protection similar to a Zener diode, which is ideal for circuits with a defined polarity. Bi‑directional devices protect against voltage spikes of either polarity, making them suitable for AC‑coupled or differential lines.

Can the 5KP30A be used in surface‑mount applications?

No, the 5KP30A is specifically designed for through‑hole mounting. For surface‑mount requirements, Rizees offers alternative TVS models that provide comparable performance in an SMD package.

How does the 5 kW rating affect the diode’s lifespan?

The 5 kW rating indicates the maximum transient power the diode can safely dissipate during a surge event. Proper thermal design and adherence to the specified voltage limits ensure long‑term reliability, even under repeated transient exposure.

Is additional cooling required for the 5KP30A in high‑current applications?

In most typical industrial applications, the diode’s built‑in thermal resistance is sufficient. However, for extremely high‑frequency or high‑current environments, adding a heat‑sink or improving airflow can further enhance thermal performance.

What warranty does Rizees provide for this product?

Rizees offers a standard one‑year limited warranty covering manufacturing defects, along with access to technical support for design and integration assistance throughout the warranty period.
