3KASMC11AHM3_A/I

TVS - Diodes

The 3KASMC11AHM3_A/I is a unidirectional Transient Voltage Suppression (TVS) diode array and is classified as such because it has the ability to absorb high energy pulses or surges in its breakdown region. It can protect against electrical transients such as ESD, lightning, electrostatic discharge, and other overvoltage conditions from coming in contact with sensitive electronics. The 3KASMC11AHM3_A/I is most commonly used in consumer electronics, automotive, industrial, and medical markets.

Applications for 3KASMC11AHM3_A/I

The 3KASMC11AHM3_A/I is best suited for applications that require transient protection and require a low to moderate capacitance. It is designed with two, five, or seven lines, depending on the chip type. As its main purpose is to prevent transients, it is most often used in consumer electronics, such as laptops, tablets, and smartphones, as well as automotive, medical, and industrial applications. It is also used in audio/visual equipment, such as televisions or gaming systems. The chip is distributed in SC-73 and SOT-523 packages.

Working Principle of 3KASMC11AHM3_A/I

The 3KASMC11AHM3_A/I works by engaging a breakdown voltage that is slightly less than the maximum voltage in the line. When this voltage passes a certain level, the 3KASMC11AHM3_A/I will start to ‘break down’ or conduct current, allowing the transient to bypass the remainder of the circuit and preventing it from entering the device.Once the voltage is below the breakdown voltage, the 3KASMC11AHM3_A/I will reset itself and become inactive again. The diode is designed to reset quickly so that it can react to any further transients if they arise.

Conclusion

The 3KASMC11AHM3_A/I is a unidirectional TVS Diode Array that is designed specifically for transient voltage suppression. It is best suited for applications requiring a low to moderate capacitance and is commonly used in consumer electronics, automotive, medical, and industrial devices. It operates by engaging a just-below-breakdown voltage that allows the transient to pass through the diode, protecting the remainder of the device from the surge.
