How do you specify a TVS diode?
Guidelines for Selecting a TVS Diode
- Select a diode with a standoff voltage that is higher than the normal operating voltage.
- Verify that the specified peak current exceeds the expected peak current.
- Calculate the maximum clamping voltage (VCL) of the selected diode.
CAN TVS 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.
What do I need to know about a TVS diode?
It is the Maximum voltage drop across the TVS diode for a particular peak pulse current. Clamping Voltage (VC). The first step in selecting a TVS diode is to determine What highest continuous peak normal operating voltage will be at the point of intended protection in the circuit.
How to use TVS diodes for transient voltage suppresison?
The primary way to protect a circuit from overvoltage is to place these TVS devices in parallel with the circuit. There are many types of TVS device that can be used for Transient Voltage Suppression namely Metal Oxide Varistor, TVS Diode, Zener Diode or a Bypass Capacitor.
How is a TVS diode similar to a varistor?
The TVS (Transient Voltage Suppression) diode is a voltage limiting protection device whose function is very similar to that of the varistor. It also uses the non-linear characteristics of the device to clamp the overvoltage to a lower voltage value to protect the subsequent circuit.
Which is maximum clamping voltage for TVS diodes?
The product of IPP and the maximum clamping voltage VC (MAX) is the maximum value of transient pulse power. TVS diodes should be selected correctly when using. The rated transient pulse power PPR should be greater than the maximum transient surge power that may occur in the protected device or line.
