What does a suppressor diode do?
Transient Voltage Suppressor diodes, which are commonly referred to as TVS diodes, are components that protect sensitive circuitry from being damaged due to high voltage transients. The primary source of high voltage transients are electrostatic discharge, electrical fast transient, and surge events.
How does a transient voltage suppressor diode work?
Transient Voltage Suppressor Diode is a clamping device, so whenever the induced voltage exceeds the avalanche breakdown voltage, it absorbs the excess energy of the overvoltage event, and then it automatically resets after overvoltage condition.
How do you test a suppressor diode?
The Diode Test procedure is conducted as follows:
- Make certain a) all power to the circuit is OFF and b) no voltage exists at the diode. Voltage may be present in the circuit due to charged capacitors.
- Turn the dial (rotary switch) to Diode Test mode.
- Connect the test leads to the diode.
- Reverse the test leads.
What is suppressor circuit?
Transient Voltage Suppressors (TVS’s) are devices used to protect vulnerable circuits from electrical overstress such as that caused by electrostatic discharge, inductive load switching and induced lightning. In a circuit, the TVS should be “invisible” until a transient appears.
What is ESD diode?
A TVS diode (ESD protection diode) is a kind of Zener diode. It is a diode that is mainly used for static electricity (ESD) countermeasures. It protects integrated circuits and others from high-voltage ESD entering from a USB line etc.
What does a transient voltage suppressor do?
Transient Voltage Suppressors (TVS’s) are devices used to protect vulnerable circuits from electrical overstress such as that caused by electrostatic discharge, inductive load switching and induced lightning.
How do you know if a diode is bad?
A diode is reverse-biased when the positive (red) test lead is on the cathode and the negative (black) test lead is on the anode. The reverse-biased resistance of a good diode displays OL on a multimeter. The diode is bad if readings are the same in both directions.
How do you know if a diode is shorted?
If the meter indicates a very high resistance or OL in both forward and reverse-biased conditions, then the diode is said to be opened. In other hand, if the meter reads a very low resistance in both directions, then the diode is said to be shorted.
What does a suppressor do in electronics?
A surge suppressor (sometimes optimistically called a “surge protector”) is a device inserted in the alternating current ( AC ) utility line and/or telephone line to prevent damage to electronic equipment from voltage “spikes” called transients.
What is ESD suppressor?
ESD Suppressor is ESD protection device using gap discharge. ESD suppressor protects Electric devices from ESD by utilizing the ability to decrease its resistance value rapidly when high voltage is applied to ESD Suppressor.
