Global semiconductor leader ST Microelectronics has introduced one of the smallest TVS diodes in the world for protecting sensitive electronics in consumer products and handhelds.

Part of a world-leading range of Transient Voltage Suppression (TVS) protection components, ST’s new TVS device, the ESDAVLC6-1BV2 has a surface-mount outline of 0.45 x 0.2mm, one size smaller than today’s 0.6 x 0.3mm devices.

Eric Paris, Product Marketing Director, ASD & IPAD Division, ST Microelectronics explains that a complete motion-sensing IC for features such as indoor navigation and advanced user interface (ST’s LSM303D) measures just 3 x 3mm, while some power chips are as small as 2 x 2mm. Trimming 0.2mm or 0.1mm from each TVS can simplify placing components and routing connections, especially if the design contains several such devices.

The ESDAVLC6-1BV2 TVS diode fully satisfies the protection requirements specified in the international standard IEC 61000-4-2. ST’s new ESDAVLC6-1BV2 has a clamping voltage half that of the nearest competing varistor in the same size package, offering greater safety for the internal components.

Key features of ESDAVLC6-1BV2 TVS diodes:

  • Bidirectional operation; single part number fulfils multiple roles on PC-board
  • Bandwidth: 1GHz
  • Line capacitance: 7.5pF
  • Breakdown voltage 6V
  • Ultra-thin 0.2mm package height
