Product Description
Bourns TBU-RS085-300-WH is a single-element bi-directional transient voltage suppression (TVS) diode designed to provide robust surge and electrostatic discharge protection, specifically optimized for the RS-485 communications interface.
This surface mount device comes in a compact DFN package measuring 8 mm in length, 5.5 mm in width, and 1 mm in height, featuring 2 pins for integrated board mounting. It delivers efficient dual channel protection while reducing component count and saving approximately 52% of board space compared to traditional discrete implementations.
The device is engineered to meet and aid compliance with important industrial standards such as IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge), ensuring superior protection against voltage spikes and transient surges.
Featuring a minimum breakdown voltage (Vbr) of 7.5 V, a maximum reverse stand-off voltage (Vwm) of 12 V, and a clamping voltage (Vc) of 20 V, the diode effectively suppresses voltage spikes. Its fast response time of 1 microsecond ensures quick transient suppression, suitable for sensitive electronic circuitry protection.
Operating temperature ranges from -55°C to 125°C, the diode is versatile for various industrial and commercial environments. It also provides electrostatic discharge (ESD) protection and complies with RoHS Directive 2015/863, supporting environmentally responsible manufacturing.
