- RoHS Compliant: Lead-free and environmentally friendly.
Ideal for Ethernet (PoE), industrial controls, and telecom systems requiring fast, reliable surge protection.

Pinout

The TBU-DF055-200-WH is a 2-pin bidirectional TBU (Transient Blocking Unit) protector.
Functions:
- Provides ultrafast overvoltage protection (responds in nanoseconds).
- Blocks high-voltage transients (up to 200V) while allowing normal signal operation.
- Bidirectional operation for AC/DC circuits.
- Low capacitance for high-speed data line protection (e.g., Ethernet, telecom).
Pinout:
- Pin 1 (IN/OUT) – Connects to the protected line.
- Pin 2 (IN/OUT) – Connects to the other side of the circuit.
Applications:
- Surge protection in PoE, industrial, and communication systems.
