Vishay Intertechnology, Inc. released a bidirectional asymmetrical (BiAs) single-line ESD protection diode in the compact new DFN1006-2A package. Saving space over solutions in SOT packages, the Vishay Semiconductors VCUT0714BHD1 offers low capacitance and leakage current for the protection of high-speed data lines against transient voltage signals.

With its working voltage range of -7V to +14V or -14V to +7V, and low load capacitance down to 8 pF typical, the diode is a standard ESD diode also suitable for interface protection in commercial applications. For automotive applications, the VCUT0714BHD1 is also available in an AEC-Q101 qualified version. Due to the short leads and small size of the DFN1006-2A package, the device's line inductance is low, allowing fast transients such as an ESD strike to be clamped with minimal over- or under-shoots.

The protection diode features a low maximum leakage current of < 0.1 μA at the working voltage of 7V or 14V; a breakdown voltage of 7.3V or 14.5V typical at 1 mA; and a maximum clamping voltage of 15V at 3.6A or 30V at 2A. The VCUT0714BHD1 provides transient protection for one data line as per IEC 61000 4 2 at ± 25kV (contact) and ± 30kV (air) discharge. The device offers a moisture sensitivity level (MSL) of 1 in accordance with J-STD-020 and a UL 94V-0 flammability rating.

RoHS-compliant, halogen-free, and Vishay Green, the protection diode supports automated optical inspection (AOI) for automotive systems. Soldering can be checked by standard vision inspection; no X-ray is required.
