ESD Suppressors exceed ESD protection standard

Offered in plastic, 3-leaded, 1.2 x 1.2 x 0.5 mm SOT-723 package, [micro]ESD dual series diodes provide 2 lines of protection for portable and battery powered applications. Models [micro]ESD3.3D and [micro]ESD5.0D clamp 30 kV ESD transients in less than 1 nsec and clamp ESD pulses to less than 7 V. ESD protection diodes feature leakage of 0.05 [micro]A in off state and capacitance of 35 pF, which makes them suitable for protecting data lines with data rates to 10 Mbps.

[micro]ESD dual series diodes provide two lines of protection for portable and battery powered applications, delivering superior ESD clamping performance and an ultra-low profile package

PHOENIX, Ariz. – August 3, 2005 – A leading global supplier of discrete devices, ON Semiconductor (NASDAQ: ONNN) today introduced the [micro]ESD (micro ESD) dual series of high performance, micro-packaged electro static discharge (ESD) protection diodes. The [micro]ESD dual series is designed to protect voltage sensitive components for two lines in applications that demand minimal board space and low profiles, such as cell phones, MP3 players and portable gaming systems.

“For designers dedicated to meeting strict ESD compliance standards, ON Semiconductor’s [micro]ESD dual devices offer a compelling alternative to commonly used Multi-Layer Varistors”, said Gary Straker, ON Semiconductor director of marketing for the Small Signal Division. “The [micro]ESD dual device can protect two lines in less board space than two 0402 MLVs, while offering numerous performance advantages by delivering lower clamping voltage, lower leakage, faster response time and ability to withstand multiple ESD strikes without undesirable shifts in electrical characteristics.”

These devices have been designed to maximize ESD suppression performance in the smallest 3-leaded plastic package on the market today. The [micro]ESD dual series clamps 30 kilovolt (kV) ESD transients – per the IEC61000-4-2 standard – in less than a nanosecond to ensure voltage sensitive components are protected. These devices clamp ESD pulses to less than 7 volts (V) to protect the most sensitive systems and minimize disruption in a circuit’s functionality.

The [micro]ESD dual series features the ultra small SOT-723 package. Boasting a 1.2 mm x 1.2 mm outline making it the ideal fit for designers that are limited in board space. The 0.5 mm profile of this package also enables designers to minimize the height of their designs without sacrificing functionality. The two line protection that this series integrates into one package further reduces required board space and system component count, thus simplifying the assembly process.

These new ESD protection devices also improve circuit efficiency and battery life with an ultra low leakage of 0.05 milliamps ([micro]A) in their off state making them ideal for handheld applications. Their low capacitance of 35 Pico farads (pF) makes them suitable for protecting data lines with data rates up to 10 Mbits/second.

“As portable electronic applications increase in the number of user interfaces and shrink in size, they become more susceptible to accidental ESD damage,” said Mamoon Rashid, ON Semiconductor general manager for the Small Signal Division. “The [micro]ESD dual series is the latest addition to ON Semiconductor’s growing portfolio of devices specifically designed to clamp ESD transients. Through leading-edge silicon design and a commitment to push the envelope on packaging, ON Semiconductor will continue to develop high-performance solutions for this challenging applications space.”
