Toshiba America is offering tiny new diode-protection chips to protect portable audio applications, mobile phones and LED matrices from static discharge.

A series of bi-directional diodes in three different packages for ESD or electrostatic discharge protection in portable audio devices, mobile phones, and LED matrices is being offered by Toshiba America Electronic Components, Inc.

Using the Toshiba DF2B6.8 Series, the parts can protect mobile and digital equipment like smart or cell phones and mobile audio players from discharge of electrostatic energy (static) that can be generated accidentally in various ways and ‘kill’ sensitive components in the electronic circuitry.

The static protection diodes are designed to be low-leakage and support AC signals that are negative or positive.  They use less space than using two diodes and can save the manufacturers money as well.

The Toshiba DF2B6.8E is offered in an ESC package that measures 1.6mm x 0.8mm x 0.6mm, and is suitable for LED matrices and exogenous dataline noise rejection.

For even more space constrained applications, such as portable audio players or audio in thin mobile devices, the Toshiba DF2B6.8CT is offered in an CST2 package that measures 1.0mm x 0.6mm x 0.38mm.

The Toshiba DF2B6.8FS is offered in an fSC package that measures 1.0mm x 0.6mm x 0.48mm, and is targeted for use with LEDs or mobile phone audio lines.

The series has a reverse breakdown voltage of 6.8V and high ESD immunity level of +/-8kV (min.) @ IEC61000-4-2 (contact discharge).
