The TVB200SA is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc. It is designed to protect sensitive electronic components from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD).

Applications

• Industrial Control Systems: Protecting PLCs, sensors, and communication interfaces.
• Telecom Equipment: Surge protection for telephone lines, network interfaces, and base stations.
• Power Supplies: Safeguarding against overvoltage conditions.
• Automotive Electronics: Protecting sensitive ECUs from voltage spikes.
• Consumer Electronics: Surge protection in televisions, audio equipment, and appliances.

Features

• Unidirectional Protection: Designed to clamp positive transients.
• Low Clamping Voltage: Provides effective protection by limiting the voltage to a safe level.
• Fast Response Time: Reacts quickly to transient events, minimizing the risk of damage.
• High Surge Capability: Withstands high surge currents without degradation.
• RoHS Compliant: Meets environmental regulations for hazardous substances.

Benefits

• Enhanced Equipment Reliability: Protects sensitive components from damage, increasing the lifespan of electronic devices.
• Reduced Downtime: Prevents failures caused by voltage transients, minimizing disruptions in operation.
• Improved System Safety: Protects personnel and equipment from hazardous voltage surges.
• Cost Savings: Avoids costly repairs and replacements of damaged components.
• Compliance with Standards: Meets industry standards for surge protection, ensuring regulatory compliance.

Additional Details

The TVB200SA has a standoff voltage of 200V. Its peak pulse power is not explicitly specified in readily available datasheets but TVS diodes of similar characteristics by Littelfuse typically offer peak pulse power ratings up to several hundred watts. The specific clamping voltage varies based on the surge current. It is available in a DO-214AA (SMB) package. The operating temperature range is typically -55°C to +150°C. The TVB200SA is suitable for protecting circuits connected to power lines or signal lines where surge events are common.
