BiAs single-line ESD protection diode saves space
Device provides low capacitance down to 8 pF typical for interface protection in commercial and automotive applications

Vishay Intertechnology has released a new bidirectional asymmetrical (BiAs) single-line ESD protection diode in the compact new DFN1006-2A package with side-wettable terminals. Saving space over products 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 -7 V to +14 V or -14 V to +7 V, and low load capacitance down to 8 pF typical, the diode released today is a standard ESD diode also good 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 very low, allowing fast transients such as an ESD strike to be clamped with minimal over- or undershoots.

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

Samples and production quantities of the VCUT0714BHD1 are available now, with lead times of 12 weeks for large orders.
