World's smallest TVS diode from ST for mobile devices

Any little space saved on mobile devices such as smart phones matter a lot for portable electronics designers. Here is one such product for circuit protection where the space is saved. STMicroelectronics said it has introduced the world’s smallest TVS diode for protecting sensitive electronics in consumer products and handhelds. As the first such device to be offered in the industry’s smallest standard surface-mount outline of 0.45 x 0.2mm, the ESDAVLC6-1BV2 is one size smaller than today’s 0.6 x 0.3mm devices, claims ST.

On the saving space value addition in smartphones and tablets Eric Paris, Product Marketing Director, ASD & IPAD Division, STMicroelectronics says “A complete motion-sensing IC for features such as indoor navigation and advanced user interface, such as 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 meets protection requirements specified in the international standard IEC 61000-4-2. This device is better than varistor because it offers more effective protection. ST says its 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. Although useful in many applications, arrestors also age, providing progressively less protection with each ESD event clamped, as per ST.


Major features of ESDAVLC6-1BV2:
• 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

Availability and price: The ESDAVLC6-1BV2 is in mass production now, and samples are also available. Prices start at $0.10 for orders of 1,000 pieces.
