Voltage transient protection diodes for NFC antenna

NXP Semiconductors N.V. has made available a new series of ESD protection devices for protecting NFC (Near Field Communication) antennas in mobile devices from voltage transients.

Key features of PESD18VF1BL and PESD24VF1BL as per NXP:

Bi-directional configuration, allowing operating voltages up to 18 V and 24 V, respectively
Very low capacitance down to 0.35 pF enabling easy design of the antenna matching circuit
Very small voltage dependency of the diode capacitance avoiding intermodulation distortion
ESD robustness of up to 10 kV according to IEC61000-4-2
Very small DFN1006-2 (0402 inch) package.

Availability: 18V PESD18VF1BL in DFN1006-2 is available now, 24 V PESD24VF1BL is expected to be available in high volume production in Q1 2014. Two further 18 V and 24 V protection diodes in the DSN0603 (0.6 x 0.3 x 0.3 mm, 0201 inch) package will be released in Q2 2014.

Price: PESD18VF1BL in DFN1006-2 is priced at US $0.05 per piece in quantities of 10,000 units
