DIN Rail Mount Clamp Diode Array Board 1N5408 3A 1000V XUHONG FR-4 PCB

Description

Product Overview

The XUHONG DIN rail mount clamp diode array module board is engineered for high‑current, high‑voltage applications where space, reliability, and ease of installation are paramount. At its core, the board houses sixteen 1N5408 diodes, each rated for 3 A continuous current and 1000 V reverse voltage, delivering a total capability that exceeds the demands of most industrial power‑conversion and protection circuits. The diodes are mounted on a FR‑4 fiberglass‑reinforced epoxy substrate, a material renowned for its dimensional stability, dielectric strength, and resistance to moisture. Dual copper layers provide low‑impedance pathways, reducing voltage drop and heat buildup while enhancing overall electrical performance.

Mechanical robustness is achieved through a fire‑proof nylon carrier that slides securely onto standard DIN rails ranging from 15 mm to 35 mm in width. The carrier incorporates a 5.08 mm (0.2 in) pitch screw terminal block, allowing wire gauges from 24 AWG (0.2 mm²) up to 12 AWG (2.5 mm²) to be terminated with confidence. Stripping length is set at 7 mm (0.28 in) to ensure consistent contact pressure, and the M3 steel screws are plated with Cr₃⁺ Zn for corrosion resistance. Pin headers and brass cages further reinforce the assembly, providing a secure, vibration‑resistant connection that meets the rigorous standards of industrial environments.

Operating temperature ranges from –20 °C to 70 °C, covering the typical climate conditions encountered in factories, data centers, and outdoor installations. The board’s compact dimensions—7.1 × 7.1 × 2.1 inches—allow it to fit within tight panel spaces while still offering ample power handling capacity. The combination of high‑quality components, thoughtful mechanical design, and extensive testing makes this module a dependable choice for power distribution, motor control, UPS systems, and any application requiring robust diode protection.

Usage

Designed for a broad spectrum of industrial scenarios, the DIN rail clamp diode array board excels in environments where reliability and ease of service are critical. In motor control panels, the board can be used to protect against voltage spikes generated during start‑up and braking, safeguarding downstream semiconductors and ensuring smooth operation. Power distribution units benefit from the board’s ability to clamp transient over‑voltages, reducing the risk of equipment failure and extending service life.

Automation systems that rely on programmable logic controllers (PLCs) often require precise voltage regulation and protection. By integrating the XUHONG module directly onto the DIN rail, engineers can provide a compact, high‑performance barrier against surges without adding extra wiring complexity. The board’s 24‑12 AWG terminal capability accommodates a variety of cable sizes, making it suitable for both low‑current sensor circuits and higher‑current actuator feeds.

For outdoor or harsh‑environment installations, the fire‑proof nylon carrier offers an added layer of safety, resisting flame spread and maintaining structural integrity under elevated temperatures. The module’s temperature rating of –20 °C to 70 °C ensures stable operation in cold storage facilities, refrigerated warehouses, and heated manufacturing floors alike. Its low profile also allows it to be stacked with other DIN‑rail accessories, optimizing panel real‑estate while preserving clearances required by electrical codes.

Maintenance technicians appreciate the quick‑release clamp design, which enables rapid removal and replacement without the need for specialized tools. This feature reduces downtime during preventive maintenance or fault rectification, contributing to higher overall equipment effectiveness (OEE) across the plant.

FAQ

What types of circuits can benefit from this diode array board?

The board is ideal for any circuit that requires protection against voltage spikes, such as motor drives, power supplies, UPS systems, and PLC input modules. Its high reverse voltage rating makes it suitable for both AC and DC applications where transient suppression is needed.

Can the module be mounted on non‑standard DIN rails?

While the carrier is optimized for standard 15‑35 mm DIN rails, it can be adapted to other rail sizes using compatible mounting brackets. However, for best performance and safety, we recommend using the specified rail dimensions.

Is the board compatible with higher current loads than 3 A per diode?

Each diode is rated for 3 A continuous current. For applications requiring higher current, multiple boards can be paralleled to share the load, provided that proper thermal management and balancing are implemented.

What warranty and support options are available?

XUHONG offers a one‑year limited warranty covering material and workmanship defects. Technical support is available via phone, email, and online resources, and extended warranty or on‑site training can be arranged upon request.

How does the fire‑proof nylon carrier improve safety?

The carrier meets IEC 60332‑1 flame‑retardant standards, meaning it resists ignition and limits flame spread. This property adds an extra layer of protection in panels where fire risk is a concern, helping to safeguard both equipment and personnel.
