TVS - Diodes

TVS (Transient Voltage Suppressor) diodes are components designed to protect a device from overvoltage, in particular transient overvoltage events. Commonly used in circuits for surge protection and ESD protection, they are a particular type of diode designed to shunt large voltages to ground. A common example of a TVS diode is part number 3KASMC20AHE3/57T.

3KASMC20AHE3/57T Application Field and Working Principle

This diode is mainly used in commercial and industrial applications, such as IT equipment, instrumentation, control system applications, and automation systems. When voltage exceeds the rated clamping or breakover voltage, the diode functions as a low-impedance path, allowing current to flow. The device then clamps the voltage to its breakdown or "clamping" voltage level and diverts it to ground, thus protecting the components in the circuit from being damaged.

The 3KASMC20AHE3/57T has a 5.5V breakdown or “clamping” voltage, and a 57A peak pulse current. It is a low capacitance diode, with a capacitance C o of 8pF at 1MHz. The device has a compact 3.5mm x 4.4mm flat package and is RoHS compliant. It can handle both unidirectional and bidirectional overvoltage protection, and offers good electrical performance with fast response time.

This TVS diode can protect sensitive equipment from high-voltage or electrostatic discharge events, and help systems maintain their operational integrity in harsh environments. The diode is designed to handle transient voltages up to 5000V, with a peak power rating of 1W. The device is equipped with a wide-angle wrap-around shield for efficient dissipation of heat, and has a low-profile construction and a low-inductance design for improved system reliability and performance.

The 3KASMC20AHE3/57T has a variety of features and benefits that make it suitable for many applications. It has a fast response time of less than 5ns, and a high surge capability of up to 2,500V/μs. The device has a low thermal resistance and can function in extreme temperatures between –55℃ and 150℃. The device is also highly reliable, and has a long service life of up to 100,000 hours. Additionally, the device is immune to surge impulse noise, and is designed to protect against overvoltages and ESD events.

In conclusion, the 3KASMC20AHE3/57T is a robust and reliable TVS diode capable of protecting a variety of commercial and industrial systems from high-voltage and electrostatic discharge events. It is designed to operate with a fast response time, and can dissipate large amounts of heat while handling transient voltages up to 5000V. The diode has a long service life and is RoHS compliant, offering a range of features and benefits making it suitable for a wide range of applications.
