Nexperia Combines EMI and ESD Protection for Usb 3.1 Type C, HDMI 2.0 and MIPI M-PHY Systems in Single Package with Tiny Footprint
Most efficient, effective and flexible solution
Nexperia, the former Standard Products division of NXP, announced three new series of common mode EMI filters with integrated ESD protection: PCMFxUSB3S, PCMFxHDMI2S and PESDxUSB3S, which provide support for USB 3.1 Type C, HDMI 2.0 and MIPI M-PHY interfaces. Using the same footprint, Nexperia’s industry-leading TrEOS ESD protection diodes are offered in the same package. System engineers will benefit from having a single device instead of two (common mode filter plus TrEOS ESD protection component) saving PCB space and improving reliability and design flexibility. With both solutions available in the same package, designers can determine at a late stage whether they need to include EMI filtering at all without being concerned about PCB layout spins. Also, the same board layout will be suitable for all markets, whether filtering is required or not. Furthermore, the new integrated common mode filters feature an extremely wide differential passband of more than 6 GHz.

Nexperia’s TrEOS ESD protection technology delivers extremely low capacitance to maintain excellent signal integrity, low clamping voltage/dynamic resistance to protect the system chip, and high ESD and surge ruggedness. By using active silicon-controlled rectification, none of these parameters are compromised. The result is an extremely fast turn-on time of about 0.5 ns that enables devices to withstand up to 20 kV contact discharge. This exceeds level 4 of the IEC 61000-4-2 standard.
Stefan Seider, product manager at Nexperia, comments, “Portable devices such as smartphones are getting smaller, requiring transmission standards such as Wi-Fi, Bluetooth and LTE together with USB3.1 data frequencies. Our combinational PCMF filters are a highly efficient solution as they are the only devices available on the market to offer both ESD protection and EMI filtering in a single package with the same footprint as ESD-only protection diodes, both for USB 3.1 data rates. Therefore, Nexperia offers the best RF performance, common mode rejection at the critical frequencies and ESD clamping, and designers can change between common mode filters with ESD and ESD-protection-only without changing the footprint.”
