Reliable transient voltage protection for automotive, industrial and energy applications

With a broad portfolio of transient voltage suppression (TVS) diodes by YAGEO, Rutronik has strengthened its circuit protection solutions for high-reliability electronic systems. Covering standoff voltages from 5V to 600V and surge power ratings from 400W up to 5,000W, the portfolio is ideal for demanding applications in automotive, industrial and energy markets.

The TVS diode series is designed to protect sensitive electronic circuits against ESD events, lightning-induced surges, load dump transients, and other voltage spikes. Thanks to their fast-clamping response, high peak pulse current capability, and stable electrical characteristics, the devices reliably limit transient overvoltages to safe levels, protecting downstream components.

Depending on the series, the TVS diodes are specified for an operating temperature range from –55C to +150C, making them suitable for harsh environmental conditions. For automotive applications, selected series are AEC-Q101 qualified, ensuring long-term reliability under temperature cycling, electrical stress, and repetitive surge exposure.

This portfolio offers high flexibility for system designers. Multiple SMD and axial package options are available, including SMA, SMBJ, SMCJ, SOD123, low-profile DFN leadless packages, and high-power axial devices. This variety allows easy integration into space-constrained PCB layouts without compromising protection performance.

Further reliability is ensured through tight parameter control, advanced wafer-level chip processing, and YAGEO’s global quality and supply network, supporting mission-critical applications in automotive, industrial, and energy systems.

Application examples include EV charging modules and OBC, automotive ECUs and BMS, power supply and DC bus transient protection, telecom and networking equipment, industrial control systems and motor drives, and consumer electronics I/O interface protection.
