NXP has introduced a series of new diodes designed to protect NFC antennas and controllers in mobile devices from electrostatic discharge.
NXP said: " NFC antennas are usually placed on the battery cover or battery and connected to NFC's integrated circuit through small contacts in the phone. These contacts open an entrance for electrostatic discharge, which could potentially harm the integrated circuit of the NFC controller. "
" This new diode can protect NFC's integrated circuit, conforming to IEC 61000 - 4 - 2 industry standards. At the same time, they can also resist the bias voltage by changing the diode capacitance, thus maintaining the signal strength of the antenna circuit. "
The 18V version is now on sale and the 24V version will be available early next year. NXP said that both versions " are very suitable for today's smartphones".
