3KASMC30AHM3_B/I is a general purpose silicon avalanche rectifier that belongs to Transient Voltage Suppressor (TVS) Diodes. It is widely used for surge and overvoltage protection. The diode uses a series arrangement of highly efficient lead-free silicon avalanche junction to protect sensitive components against overvoltage. TVS Diodes like this component provide additional protection for circuits by clamping voltage spikes that exceed the rated peak power protection.
Demand for TVS Diodes has surged in recent years as more and more applications require surge protection. This is due to the increasing complexity and sophistication of electronic circuits which are now powered by more powerful power supplies and subjected to environmental stress. The 3KASMC30AHM3_B/I is an example of a TVS Diode that is designed to protect against transients. It is capable of clamping voltage surges up to 30A, with a peak pulse power capability of 1.5kW (1000W peak for 10/1000μs). It features a low example and low voltage drop, making it suitable for use in portable devices and other applications that require low current and low voltage drop.
The working principle of the 3KASMC30AHM3_B/I involves two components, an anode and a cathode. When a transient voltage or over-voltage is applied across the anode and the cathode, the diode starts to conduct current. The Avalanche breakdown—often called Zener breakdown—occurs as electrons from the anode pass through the high-field region created by the cathode. When the voltage across the junction reaches the breakdown voltage of the diode, it quickly conducts current. The current through the diode is then limited by the series resistor connected in parallel with the diode. This reduces the surge current and provides a voltage clamping action to protect the device from high voltage transients.In most circuits, TVS Diodes are used as part of an ESD protection circuit. This is usually comprised of a PTC (polymeric positive temperature coefficient) or ESD diode in series with the TVS Diode. The PTC or ESD diode provides an additional level of protection by preventing a surge current from reaching the sensitive electronic components. The TVS Diode then clamps the voltage to protect the components from high voltage spikes.The 3KASMC30AHM3_B/I is widely used in a variety of applications from automotive and consumer electronics to industrial control, and telecom and computer components. It is typically used in portable products, audio amplifiers, power supplies, consumer and automotive electronics. It is also used in applications where high peak power protection is required.The 3KASMC30AHM3_B/I provides an excellent level of surge protection while being able to handle high power applications. Its low voltage drop, fast response time, and low capacitance make it an ideal choice for a variety of applications.
