Product Description
Bourns TBU-CA040-100-WH is a high-speed 1-element bi-directional transient voltage suppression (TVS) diode packaged in a compact 2-pin DFN surface mount type. Designed to provide optimal circuit protection, this device protects sensitive electronics from voltage and current surges caused by short circuits, power cross faults, lightning, and induction pulses.
With a maximum reverse stand-off voltage of 20V and a maximum peak pulse current of 0.2A, this TVS diode clamps transient voltages to a safe 400V level. Its low capacitance design facilitates its use in communication lines such as Ethernet, RS-485, and VDSL2 by allowing high-frequency signals to pass without degradation. The small package dimensions of 6.5mm length, 4mm width, and 0.85mm height help to save valuable PCB space.
The device operates reliably over a broad temperature range from -55°C to +125°C and complies with IEC 61000-4-2 for electrostatic discharge (ESD) protection. Its resettable nature means it can withstand thousands of fault conditions without the need for replacement, making it suitable for industrial controls, medical electronics, automated test systems, telecom, and aerospace applications.
Fast circuit protection against overcurrent and overvoltage events. Bi-directional design suitable for symmetrical voltage transients. Small SMT package for high-density PCB layouts. Wide operating temperature range from -55°C to +125°C.
Clamping voltage of 400V and peak pulse current 0.2A. Supports high-frequency applications with low capacitance. Meets IEC 61000-4-2 ESD protection standards. Maintenance-free, resettable operation.
This TVS Diode is ideal for protecting sensitive circuits in industrial, automotive, telecommunications, and aerospace environments. It provides superior surge protection while minimizing the impact on normal circuit operation and signal integrity.
