SMAJ20CA-M3/61 Application Field and Working Principle

What is the SMAJ20CA-M3/61?

The SMAJ20CA-M3/61 is a type of TVS diode, manufactured by Central Semiconductor Corporation. It is one of the company\'s most popular high power transient voltage suppressor (TVS) diodes. The SMAJ20CA-M3/61 is designed to protect sensitive equipment from the damaging effects of transient overvoltage and surge events.

SMAJ20CA-M3/61 Application Field

The SMAJ20CA-M3/61 is commonly used in a variety of applications, such as:

• Surge tolerant computer and telecom systems
• Industrial and telecom equipment
• Lighting systems
• Medical instruments and equipment

The SMAJ20CA-M3/61 is ideal for low voltage, high voltage, and general-purpose applications. It can handle high applications voltage up to 20kV and down to 7.5V and its reverse stand-off voltage range is from 6V to 24V.

SMAJ20CA-M3/61 Working Principle

The SMAJ20CA-M3/61 is designed to protect sensitive equipment and components from damaging effects of transient or surge caused by ESD, lightning, and other overvoltage events. When overvoltage events occur, the SMAJ20CA-M3/61 will automatically clamp the voltage to a safe level and prevent the equipment and components from being damaged.In order to achieve this protection, the SMAJ20CA-M3/61 utilizes the principle of avalanche breakdown. Avalanche breakdown occurs when the voltage and current at a junction become high enough to ionize air molecules within the junction. This ionization creates a conductive channel which lowers the resistance of the junction. This conductive channel allows the current to flow freely, drastically increasing the current within the junction. As the current increases, the voltage is clamped to a safe level.The SMAJ20CA-M3/61 is able to achieve a very low clamping voltage because of its high peak pulse current capability. This allows the device to withstand up to 20kV of voltage without damaging equipment and components connected to the device. The SMAJ20CA-M3/61 also features a high surge rating, making it ideal for use in high surge environments. This TVS Diode is rated for up to 1500W peak pulse power rating and 8/20uS surge waveform. These ratings make the SMAJ20CA-M3/61 one of the most reliable and powerful surge protectors on the market.

Conclusion

The SMAJ20CA-M3/61, manufactured by Central Semiconductor Corporation, is a highly reliable and powerful TVS diode designed to protect sensitive equipment and components from the damaging effects of transient overvoltage and surge events. This TVS Diode features a high peak pulse current capability, a high surge rating, and a reverse stand-off voltage range of 6V to 24V. The SMAJ20CA-M3/61 is ideal for use in a variety of applications, including surge tolerant computer and telecom systems, industrial and telecom equipment, lighting systems, and medical instruments and equipment.
