TVS Diodes & ESD Suppressors for Voltage Spike Protection
TVS (Transient Voltage Suppression) diodes and ESD (Electrostatic Discharge) suppressors are essential components for protecting sensitive electronic circuits from voltage spikes, power surges, and electrostatic discharges. These diodes and suppressors are designed to quickly absorb excess energy and prevent damage to components in consumer electronics, automotive systems, and industrial equipment. At Evelta, we offer a comprehensive selection of
TVS diodes and ESD suppressors from trusted brands like JD and Littelfuse, ensuring that your systems are well-protected from voltage-related hazards.
Types of TVS Diodes and ESD Suppressors Available
- High-Power TVS Diodes
High-power TVS diodes are ideal for applications where large voltage spikes are a concern. These diodes can handle higher power surges, providing robust protection for sensitive components. A notable example is the SMCJ78A - 78V 1500W ESD Suppressor TVS Diode 2Pin SMC DO-214AB, which offers 1500W of peak pulse power dissipation and protects circuits from high-voltage transients. This makes it suitable for automotive, industrial, and telecommunication applications where voltage spikes are common.
- Bidirectional TVS Diodes
Bidirectional TVS diodes offer protection for circuits with both positive and negative voltage spikes, ensuring comprehensive protection for components. The SMF30CA - Bidirectional 30V 1 Channel SOD-123-2 is an excellent choice for general-purpose voltage suppression in sensitive circuits, providing 30V of bidirectional protection in a compact SOD-123 package. It is perfect for consumer electronics, telecommunications, and power supply systems.
- ESD Suppressors
ESD suppressors protect against electrostatic discharges, which can damage or degrade sensitive electronic components. The SMCJ30A - 30V 1500W ESD Suppressor TVS Diode 2Pin SMC DO-214AB provides 1500W of power dissipation and is specifically designed to protect circuits from sudden ESD events. This component is ideal for use in environments where electronic equipment is regularly exposed to static electricity, such as in consumer electronics and industrial control systems.
Key Features & Benefits
- High Power Handling: TVS diodes like the SMCJ78A can handle up to 1500W of peak power, ensuring effective protection against high-energy voltage spikes.
- Fast Response to Voltage Spikes: TVS diodes and ESD suppressors are engineered to respond quickly to transient voltage events, clamping the voltage before it can damage sensitive components.
- Bidirectional Protection: Many TVS diodes, such as the SMF30CA, offer bidirectional protection, which is essential for circuits with AC signals or circuits that can experience voltage fluctuations in both directions.
- Compact Design: Components like the SMF30CA and SMCJ30A come in compact packages like SOD-123 and DO-214AB, allowing for easy integration into space-constrained designs.
- Robust ESD Suppression: ESD suppressors are designed to protect against electrostatic discharges, a common issue in environments where sensitive electronics are handled frequently.
Applications of TVS Diodes and ESD Suppressors
TVS diodes and ESD suppressors play a critical role in protecting electronics from voltage-related damage. They are used in a wide range of industries and applications, including:
- Consumer Electronics: In smartphones, tablets, and laptops, TVS diodes and ESD suppressors provide protection from voltage spikes that can occur due to power surges or electrostatic discharge.
- Automotive Systems: Automotive electronics are constantly exposed to voltage fluctuations and power surges due to the vehicle's electrical system. High-power TVS diodes, like the SMCJ78A, ensure that critical components remain protected from damaging transients.
- Industrial Control Systems: Industrial environments often experience power surges due to machinery and equipment. TVS diodes provide critical protection for control systems, ensuring stable operation even in harsh conditions.
- Telecommunication Systems: Telecommunication equipment is susceptible to voltage surges from lightning strikes or power line disturbances. TVS diodes, like the SMF30CA, protect sensitive communication circuits from transient voltage events.

How to Choose the Right TVS Diode or ESD Suppressor
When selecting the right TVS diode or ESD suppressor for your application, several key factors should be considered:
- Voltage Rating: The breakdown voltage of the TVS diode should match the operating voltage of your circuit. For example, the SMCJ78A is rated for 78V, making it suitable for higher-voltage applications.
- Power Handling: The power rating of the diode determines how much energy it can safely absorb during a transient event. High-power diodes like the SMCJ30A, with 1500W of power dissipation, are ideal for applications exposed to large voltage spikes.
- Bidirectional vs. Unidirectional: Choose a bidirectional TVS diode if your circuit handles AC signals or can experience voltage spikes in both directions. The SMF30CA offers bidirectional protection for sensitive circuits.
- Package Type: Depending on your design, you may need a compact SMD (Surface Mount Device) package for space-saving applications. Diodes like the SMF30CA in SOD-123 packaging offer a small footprint for high-density circuit boards.
