Product Details

Function

1.1. Transient Voltage Clamping

When overvoltage occurs in the circuit (e.g., lightning strikes, static electricity, inductive flyback), the TVS diode rapidly switches from a high-impedance state to a low-impedance state, clamping the voltage to a safe level (clamping voltage, Vc) and preventing downstream components from being damaged by overvoltage breakdown.

High-Current Discharge

It provides a low-resistance path for the discharge of peak pulse current (IPP), diverting transient energy to the ground and protecting the circuit from damage caused by large transient currents.

3. Ultra-Fast Response

With a response time of sub-nanoseconds, much faster than ordinary zener diodes, it completes voltage clamping before transient energy can cause irreversible damage to the circuit.

Automatic Recovery

It returns to a high-impedance state once the transient disturbance subsides, allowing the circuit to resume normal operation without manual reset or replacement.

FAQ

1) What is the difference between your 400W TVS diode and ordinary TVS diodes on the market?

Our 400W TVS diodes have stricter parameter control and more stable performance. The peak pulse power (400W) is strictly calibrated according to 10/1000μs and 8/20μs standard waveforms, with lower leakage current and junction capacitance. They are more suitable for high-speed signal lines and high-reliability scenarios (such as automotive electronics). In addition, we have a full-process quality inspection system, which ensures that the parameters of each batch of products are consistent, avoiding the problem of unstable performance of ordinary TVS diodes.

2) What certifications do your 400W TVS diodes have?

All our 400W TVS diodes have passed international environmental certifications such as RoHS, complying with global environmental protection requirements. Each batch of products will provide a test report to ensure that the quality meets the standards.

3) What is your delivery cycle for 400W TVS diodes?

For standardized 400W TVS diode models, the delivery cycle is about 15 working days. We will try our best to shorten the cycle to meet your project progress requirements.

4) Do you provide technical support after purchase?

Yes, we provide 7×24-hour professional technical support. Our technical team can help you with product selection, application circuit design, fault diagnosis and other issues. If you encounter any problems in the process of using our 400W TVS diodes, you can contact us at any time, and we will give a solution within 24 hours to ensure the smooth progress of your project.

5) Can you provide sample testing before mass purchase?

Of course. We can provide free samples of 400W TVS diodes for your testing and verification. You only need to provide your specific needs (such as voltage, package), and we will send the samples to you as soon as possible. After you confirm that the samples meet your requirements, we will carry out mass production and delivery to ensure that the mass products are consistent with the samples.
