Nexperia launches 48V ESD protection diodes designed for automotive data lines
Nexperia, a leading semiconductor manufacturer, has unveiled a groundbreaking portfolio of electrostatic discharge (ESD) protection diodes, specifically designed for 48V data communication networks in electric and hybrid vehicles. The new portfolio includes six robust devices that meet the stringent automotive AEC-Q101 standard, ensuring reliability under automotive conditions [1][3][4][5].
**Key Highlights of Nexperia’s New ESD Diodes:**
- **Higher Voltage Tolerance:** Engineered to handle the higher reverse working voltages found in 48V automotive systems, these diodes offer a reliable solution where conventional ESD protection devices often fall short [1]. - **Robust Protection Against ESD Events:** The new ESD diodes effectively safeguard delicate communication networks from damaging electrostatic discharges that could otherwise impair or destroy sensitive electronics in vehicles [1][3][4][5]. - **Automotive-Grade Quality:** The devices meet AEC-Q101 qualification, demonstrating their suitability for the demanding automotive environment, including temperature extremes and mechanical stress [1].
**Applications in Electric and Hybrid Vehicles:**
These ESD protection diodes are intended for use in 48V data communication networks within electric and hybrid vehicles, protecting communication lines that carry critical control and sensor data [1][3][5]. By ensuring communication reliability in 48V systems, Nexperia’s new portfolio contributes to safer and more efficient operation of EV and hybrid vehicle components, which increasingly rely on robust high-voltage data networks for functional safety and performance [1][4].
The new portfolio includes part numbers PESD2CANFD54VT-Q, PESD2CANFD60VT-Q, and PESD2CANFD72VT-Q, available in VT and LT variants. All six variants are offered in SOT23 packages, ensuring consistent ESD protection performance for 48V EV architectures [2].
Until now, designers had to rely on less efficient solutions such as parallel-connected 36V diodes or adding separate 12V rails for 48V systems in EVs and HEVs. However, Nexperia’s new ESD diodes, optimized for legacy automotive protocols such as CAN, CAN-FD, LIN, and FlexRay operating at higher board voltages [6], offer a more efficient and reliable alternative.
With this innovative portfolio, Nexperia continues to push the boundaries of semiconductor technology, providing solutions that cater to the evolving needs of the automotive industry. The new ESD protection diodes are poised to play a crucial role in enhancing durability and safety in electric and hybrid vehicles.
