The TBU-CA065-200-WH is a transient blocking unit (TBU) manufactured by Bourns. Below are its key specifications, descriptions, and features:

Specifications:

• Part Number: TBU-CA065-200-WH
• Manufacturer: Bourns
• Type: High-Speed Protector (TBU)
• Maximum Working Voltage (VWM): 65 V
• Maximum Breakdown Voltage (VBR): 200 V
• Hold Current (IHOLD): 100 mA (typical)
• Trip Current (ITRIP): 200 mA (typical)
• Response Time: < 1 µs
• Operating Temperature Range: -40°C to +85°C
• Package: SOT-23-6

Descriptions:

• The TBU-CA065-200-WH is a solid-state, high-speed protection device designed to block transient overvoltage and overcurrent events.
• It provides bidirectional protection and is commonly used in communication lines (e.g., Ethernet, RS-485, CAN bus).
• Unlike traditional fuses or TVS diodes, the TBU reacts quickly to fault conditions, isolating the protected circuit.

Features:

• Fast Response: Blocks transients in less than 1 µs.
• Bidirectional Protection: Guards against both positive and negative surges.
• Low Capacitance: Minimizes signal distortion in high-speed data lines.
• Resettable: Automatically resets after fault removal.
• Compact SOT-23-6 Package: Suitable for space-constrained applications.
