Bourns 1-Element Bi-Directional TVS Diode, 20V Reverse Stand-off, 0.1A Peak Pulse Current, Surface Mount TBU-CA050-050-WH

Bourns TBU-CA050-050-WH is a 1-Element Bi-Directional Transient Blocking Unit (TBU) designed for protecting sensitive electronic components from high voltage surges and overcurrent faults. Featuring a surface mount DFN package, it offers a low capacitance and fast response to potentially damaging transient events.

This device is optimized for industrial controls, medical electronics, automated test systems, and military/aerospace applications requiring superior circuit protection. The TBU limits energy transfer within rated limits, thus prolonging product life and enhancing circuit reliability.

The TBU-CA050-050-WH operates from -55°C to +125°C and withstands peak pulse currents up to 0.1 A, with a maximum clamping voltage of 500 V. Its bidirectional configuration allows protection against both positive and negative surges, making it ideal for telecom and data line interfaces such as Ethernet and RS-485. The small DFN package saves valuable PCB space without compromising protection performance.

This component complies with IEC 61000-4-2 for electrostatic discharge, providing an essential safeguard against ESD events. It is maintenance-free and resettable, allowing thousands of cycles without replacement, thus reducing downtime and service costs.

Single element, bi-directional diode suitable for surface mount technology (SMT) applications. Protects against short circuits, voltage surges, lightning, and power cross faults quickly and effectively. Offers ultra-fast overcurrent protection to prevent damage to sensitive electronics.

Eliminates the need for large shunt protection devices by interrupting harmful currents in under one microsecond. Low capacitance design allows it to pass high-frequency signals such as VDSL2 without degradation. Compact DFN package dimensions: 6.5 mm length, 4 mm width and 0.85 mm height.

Wide operating temperature range from -55°C to +125°C ensuring robust performance in diverse conditions. Supports protection in industrial, telecommunications, medical, military and aerospace electronic applications.
