ESD diode for interface protection

28 July 2021 Circuit & System Protection

Vishay 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 solutions in SOT packages, the 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 part is a standard ESD diode that is also good for interface protection in commercial applications. For automotive applications, it 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 under-shoots.

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 rating. The device offers a moisture sensitivity level (MSL) of 1 in accordance with J-STD-020 and a UL 94 V-0 flammability rating.
