Bourns 1-Element Bi-Directional TVS Diode 2-Pin Surface Mount DFN Package TBU-CA025-100-WH

Bourns TBU-CA025-100-WH 1-Element Bi-Directional TVS Diode in a 2-pin DFN surface mount package is a high-speed, resettable surge protector designed to safeguard sensitive electronics from transient voltage events. Its single element bi-directional configuration offers superior protection against overcurrent and overvoltage conditions.

The diode has a maximum reverse stand-off voltage of 20V and clamps voltage up to 250V, ensuring effective voltage limiting within rated conditions. The device supports ESD protection per IEC 61000-4-2 standards and can handle peak pulse currents up to 0.2A.

Operating reliably across a temperature range from -55°C to +125°C, this TVS diode is suitable for harsh environments and demanding industrial applications. Its compact dimensions of 6.5mm in length, 4mm in width, and 0.85mm in height facilitate compact PCB layouts and integration in space-constrained designs.

Bourns TBU Series devices are optimized for protection of industrial controls, medical equipment, automated testing systems, and communications equipment such as Ethernet and RS-485 ports. The bi-directional design effectively protects circuits from surges caused by lightning, induction, AC power cross, and short circuits.

Features include ultra-fast overcurrent response, low let-through energy, and minimum overshoot voltage, which together improve circuit reliability and longevity. Resettable functionality minimizes maintenance by automatically restoring protection after fault conditions are cleared.

Applications include telecom line protection where high frequency signals such as VDSL2 require low capacitance protection devices. The diode’s surface mount format supports automated assembly and reduces board space requirements.

The diode features a single element and a bi-directional configuration for versatile surge protection. Designed for surface mount technology with a compact 2-pin DFN package for space saving. Maximum reverse stand-off voltage is rated at 20V with clamping voltage at 250V.

Operating temperature ranges from -55°C to +125°C for wide environmental tolerance. Offers ESD protection compliant with IEC 61000-4-2 standards to safeguard against electrostatic discharge. Maximum peak pulse current rating of 0.2A provides robust surge handling capability.

Small physical dimensions: length 6.5mm, width 4mm, height 0.85mm ensure easy PCB integration.
