Product Description
Bourns TBU-CA050-050-WH is a single-element bi-directional TVS diode housed in a 2-pin DFN surface-mount package. Designed for high-speed, resettable circuit protection, this device responds rapidly to overcurrent and overvoltage conditions to safeguard sensitive electronic components.
With a maximum reverse stand-off voltage (Vwm) of 20 V and clamping voltage of 500 V, it limits transient voltage spikes to within safe levels. The device operates between -55°C and +125°C, making it suitable for various industrial environments.
Application areas include industrial controls, medical electronics, automated testing equipment, telecom systems, and aerospace. It effectively blocks surges caused by short circuits, AC power cross, induction, and lightning surges.
This TVS diode incorporates ESD protection compliant with IEC 61000-4-2, providing defense against electrostatic discharge events. The device’s resettable function ensures maintenance-free operation over thousands of cycles, eliminating the need for fuse replacements.
The compact dimensions (height 0.85 mm, length 6.5 mm, width 4 mm) allow for space-saving PCB designs, while its low capacitance preserves high-frequency signal integrity - a key factor for protecting Ethernet, RS-485, HART, and VDSL2 interfaces.
Compact 2-pin DFN surface mount package. Maximum reverse stand-off voltage of 20 V and clamping voltage of 500 V. Operating temperature range from -55°C to +125°C. ESD protection conforming to IEC 61000-4-2 standard. Resettable and maintenance-free design for thousands of cycles.
Ultra-fast overcurrent protection with 0.1 A peak pulse current. Low capacitance suitable for high-frequency signal lines. Ideal for industrial, medical, telecom, and aerospace applications.
This Bourns TBU series TVS diode is an optimal solution for protecting high-speed data and power circuits from damaging surges, ensuring longevity and reliability of electronic systems.
