81CNQ035SMS2 Diodes - Rectifiers - Arrays

81CNQ035SMS2 is a diode array designed to provide a low on-state voltage drop in both unidirectional and bidirectional applications. It has a low forward voltage drop and a very low leakage current, providing a high efficiency and robustness for a wide range of applications. It can be used in various circuit designs such as voltage regulation, reverse polarity protection, and rectification.

Application Field

81CNQ035SMS2 is commonly used in power supply and switched-mode power supply (SMPS) applications. It can be used in ac-dc and dc-dc converters, inverters, motor drives, and other circuitry requiring rectification or reverse polarity protection. This diode array is suitable for applications where the supply current between 20mA and 3A. It is also suitable for high frequency, low voltage operation up to 100kHz.

Working Principle

The 81CNQ035SMS2 is an integrated diode array with an n-type and p-type semiconductor connected in series. When connected in an electrical circuit, the diode array works according to the principles of rectification and reverse polarity protection. The rectification principle states that when the positive voltage reaches the anode of the diode, electrons will flow from the n-type side to the p-type side and create a current which can be regulated with the input voltage. In the case of reverse polarity protection, the diode array acts as an open-circuit, meaning that no current will flow if a negative voltage is applied to the diode array.The diode array also features a low forward voltage drop, which reduces power dissipation in the circuit leading to higher efficiency of the system. Furthermore, it has very low reverse current leakage, which reduces power losses and helps to provide reliable operation throughout the full load range.

Package

The 81CNQ035SMS2 comes in a SO-8 package and is lead-free RoHS compliant. It has low thermal resistance and is ESD-SOA rated for improved system reliability. The diode array is also designed to meet strict environmental conditions as it is designed for shallow soldering.

Conclusion

The 81CNQ035SMS2 diode array is a reliable and robust solution for many applications that require rectification and reverse polarity protection. Its low forward voltage drop, low leakage current, and low thermal resistance make it an ideal choice for power supply and SMPS applications. It also features a long-life design and is RoHS compliant.
