New Vishay semiconductor CLP series of ESD protection diodes to be distributed by New Yorker Electronics

11 April 2022

New Yorker Electronics has announced Vishay’s release of its new CLP series of electrostatic discharge (ESD) protection diodes/EMI filters. The series includes three types of devices: single-line ESD protection diodes, a four-line ESD protection diode array and a two-channel electromagnetic interference (EMI) filter.

The Vishay Semiconductors’ VBUS and VCUT single-line ESD diodes are housed in the ultra-compact 0.27 mm x 0.3 mm x 0.6 mm CLP0603-2L package. They are bidirectional and symmetrical ESD protection devices that clamp positive and negative overvoltage transients to ground. Connected between the signal or data line and the ground, they offer high isolation (low leakage current, low capacitance) within the specified working range. Due to its short leads and small package size, the diode’s line inductance is very Source: New Yorker ElectronicsSource: New Yorker Electronicslow, allowing fast transients such as an ESD-strike to be clamped with minimal over- or undershoots.

The four-line VBUS54FD-SD1 four-line diode is housed in the 0.27 mm x 0.7 mm x 1.0 mm CLP1007-5L case. It possesses the characteristic of a Z-diode with a high ESD immunity and a very low capacitance. With the VBUS54FD-SD1, four high-speed data lines can be protected against transient voltage signals like ESD. Connected to the data line (pin 1, 3 and pin 4, 5) and to ground (pin 2) negative transients will be clamped close below the ground level while positive transients will be clamped close above the 5.5 V working range. The clamping behavior of the VBUS54FD-SD1 is bidirectional but asymmetrical and so it offers optimal protection for applications running up to 5.5 V.
The VEMI256A-SD2 2-channel EMI filter with ESD protection is designed in the ultra compact CLP1007-5M package. It too is 0.27 mm x 0.7 mm x 1.0 mm and weighs only 0.45 mg. It provides low leakage current, a line resistance of RS = 60 Ohm and a typical cut off frequency of f3dB = 60 MHz.
The entire chip-level package series supplied by New Yorker Electronics offers a working range of ±3.3 V to ± 15 V with low leakage current of less than 0.0 5 µA and a low capacitance of under 0.4 pF. The operating temperature range is between -55° C and +150° C which is ideal for usage in smartphones, gaming systems, digital cameras, wearables and automotive devices. They are RoHS compliant and use lead-free terminations. Because of the very low capacitance of the VBUS03B1-SD0, it can also be used for high-speed data ports like HDMI, USB 3.0 or Thunderbolt.
