Protecting against negative and positive spikes

Toshiba Electronics Europe (TEE) has launched an ultra-miniature bidirectional ESD (Electrostatic Discharge) protection diode that provides protection against both negative and positive voltage spikes. While protection of general data lines requires only a negative clamping voltage, it is necessary to offer both positive and negative clamping when protecting audio lines. To support these requirements the new DF2B6.8FS comes as a bidirectional diode with positive and negative clamping voltages of 6.8V. The DF2B6.8FS offers a minimum ESD immunity level of +/- 8kV in accordance with the IEC61000-4-2 contact discharge standard.

Toshibas new diode is supplied in an ultra-miniature, low-profile two-pin fSC package measuring just 1.0mm x 0.6mm x 0.48mm. As a result it is ideal for applications that require high component densities because board space is at a premium.

The DF2B6.8FS will operate with junction temperatures up to 150C and has a typical breakdown voltage of 6.8V (@1mA) in both directions. Typical capacitance at 1MHz and 0V is rated at 15pF.
