About TVS Diode

referred to as TVS, is a high-efficiency circuit protection device in the form of a diode. When the two poles of the TVS diode are impacted by reverse transient high energy, it can change the high impedance between the two poles into low impedance at a speed of 10-12 seconds, absorbing surge power up to several kilowatts, causing the two poles to The voltage between them is clamped at a predetermined value, effectively protecting precision components in electronic circuits from damage by various surge pulses. Specifically, it has the following three characteristics: 1. Adding TVS diodes to signal and power lines can prevent microprocessors or microcontrollers from instantaneous surges, such as electrostatic discharge effects, AC power surges and switching power supply noise. of failure. 2. The electrostatic discharge effect can release pulses of more than 10,000V and 60A, and can last for 10ms; while ordinary TTL devices will be damaged when encountering 10V pulses of more than 30ms. The use of TVS diodes can effectively absorb pulses that can cause device damage and eliminate interference (Crosstalk) caused by switching between buses. 3. Placing TVS diodes between signal lines and ground can prevent data and control buses from being affected by unnecessary noise.
