A TVS diode is a clamping device that acts like a Zener, while a TSPD is a thyristor-based device that switches to a low-impedance state, allowing it to handle higher currents with lower clamping voltage.
TVS - Thyristors Component Intelligence
Precision surge protection for high-energy transient suppression.
What are TVS - Thyristors components?
TVS Thyristors, or Thyristor Surge Protection Devices (TSPDs), provide robust overvoltage protection by switching to a low-impedance state during a surge. They are ideal for telecom and industrial applications requiring high current handling and fast response times.
How to Choose TVS - Thyristors Components
Select based on the specific surge environment and the clamping characteristics required for your signal or power path.
Breakover Voltage (VBO)
Ensure the VBO is higher than the maximum operating voltage of the circuit to prevent false triggering.
Peak Pulse Current (IPP)
Match the IPP rating to the expected surge energy levels defined by standards like IEC 61000-4-5.
Capacitance
For high-speed data lines, select low-capacitance devices to maintain signal integrity.
Holding Current (IH)
The device must have an IH higher than the circuit's normal operating current to ensure it resets after the surge.
Package Thermal Profile
Verify the package can dissipate heat during repeated surge events without degrading performance.
