Are TVS diodes ESD sensitive?

Are TVS diodes ESD sensitive?

TVS diodes are available in industry footprints and custom sizes, with nominal reverse working voltages from 3.3 V to 70 V and diode capacitances down to 0.15 pF. The products meet 30 kV ESD withstand ratings and 2 kW of peak power dissipation on an 8/20 µs waveform without significant degradation.

What is the difference between TVS and ESD diode?

Technically there is no difference between ESD and TVS diodes. They serve the same purpose by shunting large current due to overvoltage to protect integrated circuit. However, TVS diodes are typically a much bigger devices compared to ESD and withstand much higher transient current compared to ESD.

How do I choose a ESD diode?

To obtain good ESD protection performance, select a TVS diode with the clamp voltage higher than the line voltage. Select a TVS diode with a guaranteed ESD tolerance level higher than the system’s ESD immunity requirement.

Can ESD diode?

A bidirectional TVS diode can protect the CAN transceiver bus pins for short overvoltage events. TVS diodes offer the most effective protection against ESD, burst EFT, and surge transients because of short response times of a few picoseconds and power ratings up to several kilowatts.

How do you select a TVS diode for lightning protection?

Select a diode with a standoff voltage that is higher than the normal operating voltage. Ensure that the TVS diode maximum clamping voltage is less than the abs max rating of all the devices on the line to be protected.

When would you use a TVS diode?

TVS Diodes are used to protect semiconductor components from high-voltage transients. Their p-n junctions have a larger cross-sectional area than those of a normal diode, allowing them to conduct large currents to ground without sustaining damage.

Are TVS diodes necessary?

Transient Voltage Suppressor or TVS diodes are an effective solution to protect other semiconductors from any damaging surge levels they may be exposed to.

What is clamping voltage in ESD diode?

Remember that an ESD diode is placed in parallel with the protected circuitry, so the clamping voltage is the voltage that will be dropped across both diode and the downstream circuitry. Here is a plot in the time domain that shows an 8 kV IEC strike that is discharged into a system.

What is clamping voltage of TVS diode?

starts conducting (clamping) at the minimum breakdown voltage (6V: VBR@IR) in a negative direction, there will be a increase in current in the positive direction of the 8/20µs pulse. When the transient current drawn by the PSD05C is at 1 Amp, the device clamping will be at 9.8 Volts.

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.
