Description

Product Overview

The MDK 110A-16 blocking diode, manufactured by LCTC, is engineered for demanding photovoltaic and solar energy applications where reliability and high current capacity are essential. With a forward current rating of 100 A and a peak reverse voltage capability of 1600 V, this diode offers robust protection against reverse polarity and voltage spikes that can damage solar cells and panels. Its compact form factor—measuring 1.03 × 1.07 × 3.67 inches and weighing just 5.6 oz—makes it easy to integrate into a variety of system layouts, from small residential arrays to larger commercial installations. The device is classified as a high‑current rectifier diode, often used in one‑way inline configurations, and can be configured as a dual diode by utilizing pins 2 and 3 simultaneously. The part number FFEJG620 ensures precise identification for inventory and replacement purposes, while the included specifications such as AC rating (< 400 VAC) and DC range (3‑1000 VDC) provide clear guidance for designers.

Usage

Designed for solar panel arrays, photovoltaic modules, and other renewable energy systems, the MDK 110A-16 excels in environments where high current flow and voltage tolerance are required. Installers typically place the diode in series with solar cells to prevent back‑feeding during low‑light conditions, safeguarding the entire array from damage. Its ability to handle resistive loads up to 50 A makes it suitable for battery charge controllers, inverter input stages, and DC‑DC converters. When paired with an appropriate heatsink—available in our store—the diode maintains optimal temperature performance even under continuous high‑current operation. The device’s versatility also extends to industrial electrical applications, such as motor control circuits and power distribution panels, where reverse‑bias protection is critical for equipment longevity.
