Bourns 1-Element Bi-Directional TVS Diode 2-Pin DFN 20V Maximum Reverse Stand-off Voltage 0.2A Peak Pulse TBU-CA025-100-WH

Bourns TBU-CA025-100-WH 1-Element Bi-Directional TVS Diode 2-Pin DFN is engineered as a high-speed transient blocking unit designed to protect sensitive and industrial electronic circuits from voltage and current surges. This surface mount device fits compact PCB designs due to its small DFN package with a length of 6.5 mm, width of 4 mm, and height profile of 0.85 mm.

The device features a single bi-directional diode element with a maximum reverse stand-off voltage of 20 volts and a clamping voltage of 250 volts, ensuring effective surge suppression. It supports a maximum peak pulse current of 0.2 amperes and provides robust electrostatic discharge protection compliant with IEC 61000-4-2 standards. The operating temperature range from -55°C to +125°C guarantees reliability across varied industrial and commercial environments.

Designed for applications including industrial controls, medical devices, automated test equipment, and telecommunication systems, the TBU-CA025-100-WH limits damaging surges caused by short circuits, lightning, and AC power cross events. Its resettable fuse characteristics allow the device to automatically reset after fault conditions clear, eliminating the need for fuse replacement and facilitating greater maintenance efficiency.

Special features include ultra-fast overcurrent protection preventing damaging currents from reaching critical circuitry in under one microsecond. The low capacitance design makes it suitable for high-frequency signal lines such as Ethernet, RS-485, HART, and VDSL2, where high bandwidth operation is essential.

Single element diode configuration ensures reliable bidirectional protection. Surface mount DFN package fits compact PCB layouts with dimensions 6.5 mm length and 4 mm width. Maximum reverse stand-off voltage of 20 volts protects circuits against voltage transients.

Capable of 0.2 amperes peak pulse current to handle surges effectively. Operating temperature range from -55°C to 125°C for harsh environment stability. Provides IEC 61000-4-2 Electrostatic Discharge (ESD) protection for sensitive electronics.

Small height profile of 0.85 mm aids space saving in electronic design implementations. Resettable fuse action improves product lifecycle with maintenance-free automatic resets. Ideal for industrial controls, medical electronics, and telecom surge protection applications.

Blocks surges from short circuits, AC power cross, induction, and lightning events quickly.
