CMSH3-40 BK Datasheet/PDFDiodes - Rectifiers - Single
CMSH3-40 BK is a rectifier single diode device used for various indoor and outdoor applications, especially to restrict current flow in one direction. It is also used for power conversion as well as regeneration of voltage levels. This single diode is known for its excellent electrochemical stability.
The device is designed to support a high voltage rating of 32.0 V, with a total Max. Reverse Leakage current rating of 40 µA. It also offers maximum Forward Voltage Drop at 30 mV and the Max. Power Dissipation rating at 1.2W. It is suitable for a wide range of DC applications, such as in electronic equipments, automobiles and telecommunications.
Working Principle
The CMSH3-40 BK we have today works similarly to any diode device. It’s a two-legged device, with an anode and cathode. As current enters the device, it passes through its cathode, and out through its anode. This allows the device to restrict current from running in the opposite direction.
Unlike other rectifier devices, the CMSH3-40 BK is able to achieve greater power dissipation ratings, which enables it to supports higher voltages. Additionally, it is able to provide greater current rating due to its low forward voltage drop.
Application Fields
This single diode is suitable for a wide range of applications such as over-voltage protection, DC motor control, and over-current protection. Additionally, the device can also be used for power strip capacitor, LCD backlight, and voltage rectification.
The CMSH3-40 BK is an essential component in automotive systems, as it can provide current-limiting protection in applications such as ABS, EPS and HID. This versatile device is also suitable for Telecommunications applications like Digital Subscriber Lines, PoE systems and optical transceivers.
In the industrial sector, the device can be used for front-end protection circuits and voltage converter designs. It is also widely used in metering systems and power supplies.
Advantages
The CMSH3-40 BK single diode provides excellent electrochemical stability, with a low power dissipation rating that enables it to operate at high voltages. It offers an efficient current and voltage regulation, and its low forward voltage drop allows it to support large current ratings. In addition, it is also highly-resistant to vibration, shock, and temperature.
