Key Factors to Consider When Choosing TVS Diodes

TVS diodes are widely used to protect circuits from voltage spikes. Choosing the right TVS diode suppliers is crucial. Here are several key factors to consider when selecting a TVS diode.

Determining the Operating Voltage Range

When choosing a TVS diode, it's important to first understand the operating voltage of the circuit and select a suitable diode. The peak reverse working voltage of the TVS diode should be higher than the normal operating voltage of the circuit but not too high to avoid compromising protection. Refer to the datasheets provided by TVS diode suppliers to ensure the selected diode meets the circuit's requirements.

Surge Current Handling Capacity

The surge current handling capacity of the TVS diode determines how well it can handle voltage spikes. When selecting a diode, ensure that it can withstand the maximum surge current that may occur in the circuit. TVS diode suppliers typically provide surge current ratings, which can help users choose the appropriate model.

Selecting the Right Package Type

TVS diodes come in various package types, such as SMD (Surface-Mount Device) and DIP (Dual In-line Package). Based on the PCB design, choose the appropriate package type, especially for space-constrained electronic products where SMD packages are more common. Additionally, the package type also impacts heat dissipation and installation method.

Clamping Voltage and Response Time

Clamping voltage is the ability of the TVS diode to limit the peak voltage, while response time determines how quickly it can suppress overvoltage. When choosing a diode, ensure that the clamping voltage meets the circuit's requirements and that the product has a short response time for prompt protection.

Choosing Reliable TVS Diode Suppliers

Selecting reputable TVS diode suppliers is crucial. Well-known brands typically offer high-quality products and comprehensive after-sales service, ensuring the long-term stable operation of the products.

When selecting a TVS diode, consider factors such as operating voltage, surge current handling capacity, package type, and clamping voltage. At the same time, choose reliable TVS diode suppliers to ensure effective circuit protection and prevent damage from voltage spikes.
