Bourns 1-Element Bi-Directional TVS Diode 2-Pin DFN, 20V Reverse Stand-off, 650V Clamping Voltage TBU-CA065-300-WH

Bourns TBU-CA065-300-WH 1-Element Bi-Directional TVS Diode in a compact 2-pin DFN package offers effective circuit protection for sensitive electronics and industrial equipment. This Surface Mount Technology device is designed to provide ultra-fast response to excessive voltage or current surges, making it ideal for industrial controls, telecom, medical electronics, automated test systems, and military applications.

The transient blocking unit (TBU) technology provides a resettable fuse function that limits energy transfer to protected circuits by rapidly switching to a high resistance state during fault conditions. This feature enables protection against short circuits, AC power cross, induction, and lightning surges with a maximum peak pulse current rating of 0.6 A.

The device operates bi-directionally with a maximum reverse stand-off voltage of 20 V and clamps surges at 650 V, making it suitable for ports with high-frequency signals like Ethernet and VDSL2. Operating temperature ranges from -55°C to +125°C, ensuring reliability in harsh environments.

With a small 6.5 mm length, 4 mm width, and 0.85 mm height, the DFN package saves valuable board space while offering compliance with ESD protection standard IEC 61000-4-2. The TBU-CA065-300-WH eliminates the need for larger shunt protection devices and reduces stress on the PCB, increasing product life and operational reliability.

This device is an optimal choice for applications requiring circuit protection that combines fast response, resettable operation, and high surge current handling capability in a compact SMT form factor.

Provides ultra-fast overcurrent and overvoltage protection within rated limits. Features a maximum reverse stand-off voltage of 20 volts and a clamping voltage of 650 volts. Designed as a small, low-capacitance Surface Mount Technology (SMT) package.

Rated for a maximum peak pulse current of 0.6 ampere and operating temperature range from -55 to 125 degrees Celsius. Bi-directional diode configuration suitable for high frequency signals such as VDSL2. Resettable and maintenance-free, capable of thousands of automatic reset cycles.

Compatible with Ethernet, RS-485, and HART ports for surge protection. Ensures low let-through energy and reduced stress on circuit boards for enhanced reliability. Compliant with ESD protection standard IEC 61000-4-2.
