Bourns 2-Element Uni-Directional TVS Diode 18V Reverse Stand-off Voltage 0.2A Max Pulse Current DFN 4-Pin TBU-DT065-100-WH

Bourns TBU-DT065-100-WH is a 2-element uni-directional TVS diode designed for high speed circuit protection in sensitive electronic applications. This device features a dual diode configuration in a compact 4-pin DFN package measuring 5mm by 5mm by 0.85mm, allowing for efficient surface mounting on printed circuit boards.

Providing a maximum reverse stand-off voltage of 18 volts and a clamping voltage of 650 volts, the diode effectively protects circuits from transient voltage surges caused by events such as lightning strikes, inductive load switching, and electrostatic discharges. Its maximum peak pulse current rating of 0.2 amperes ensures rapid response to overcurrent conditions, thereby safeguarding downstream electronics from damage.

With an operating temperature range from -40°C to 125°C, this device is suitable for use in industrial, automotive, medical, and telecommunications environments where reliability under extreme conditions is critical. The low capacitance characteristic allows it to perform well in high-frequency applications, such as Ethernet communications and data lines.

The TBU-DT series incorporates fast-acting resettable fuse functionality, automatically returning to a low resistance state once fault conditions cease and power is removed, enabling maintenance-free operation for thousands of cycles.

Typical applications include protection of Ethernet ports, security systems, power supplies, transformers, process control equipment, automotive electronics, and medical instrumentation. The device is manufactured in China and conforms to the Bourns TBU series specifications but does not have automotive-specific approvals or recognized standards certifications.
