Protecting Electronics Against Overvoltage Using TVS Diodes

JGSemi TVS Diodes - Protection of Electronics Against Overvoltage

In consumer and industrial electronics, increasing attention is being paid to protecting circuits against overvoltage that may occur in power supply or signal lines. Even short voltage spikes can damage sensitive components and disrupt the operation of an entire device. For this reason, special protective components are used to quickly suppress such phenomena and dissipate excess energy.

One of the most commonly used solutions is JGSemi TVS diodes, available in many voltage variants and intended for a wide range of applications - from simple electronic circuits to advanced control systems.

Key features:

• Extremely fast response time (in the picosecond to nanosecond range),
• Voltage clamping to a level dependent on surge current,
• Passive operation mode - no impact on the circuit under normal conditions,
• Working voltage (VRWM) matched to the protected line,
• Availability of unidirectional (A) and bidirectional (CA) versions,
• Available in SMD packages (e.g. SMB / DO-214AA) for automated assembly.

Applications of TVS diodes:

• Power supply systems for electronic devices - Protect against overvoltage occurring in power lines.
• Automation and control systems - Protect controller inputs and outputs against interference and voltage spikes.
• Communication lines and data transmission - Limit overvoltage and ESD discharges in signal paths.
• Automotive electronics - Protect circuits against voltage spikes in vehicle electrical systems.
• Consumer electronics, RTV and household appliances - Increase device resistance to mains overvoltage.
• Microcontrollers and digital circuits - Protect ports against ESD and transient disturbances.
