ON Semiconductor, a supplier of high-performance, energy-efficient silicon solutions, has introduced four 30V Schottky barrier diodes.

The Schottky barrier diodes are housed in an ultra-small 0201 dual-silicon no-lead (DSN2) chip-level package.

The diodes are available with low forward voltage or low reverse current at forward current ratings of either 100mA or 200mA.

The devices are suitable for the increasing number of applications where board space is restricted, such as mobile phone handsets, MP3 players and digital cameras.

The Schottky diodes feature solderable metal contacts under the package that are claimed to enable 100 per cent utilisation of the package area for active silicon.

The 0201 DSN-2 package - which measures 0.6mm x 0.3mm x 0.3mm - provides three times the board space savings compared to the SOD-923 (also known as 0402), which measures 1.0mm x 0.6mm x 0.4mm.

Providing low leakage currents, the devices are intended to help designers address power losses, efficiency and switching speeds.

The new Schottky diodes are said to have a significant performance-per-board-area advantage compared to competing parts housed in traditional plastic moulded packages.

Power management characteristics also serve to help to prolong battery life in portable equipment applications.

The NSR0xF30NXT5G series of devices is optimised for low forward voltage drop (Vf) and 370mV at 10mA.

The NSR0xL30NXT5G series of devices is designed for low reverse current (Ir) and 2.0uA at 10V reverse voltage; the devices also offer low leakage, extending battery life.

With ESD ratings of Human Body Model: Class 3B and Machine Model: Class C, coupled with low thermal resistance, the two series help support design engineers challenged with incorporating ever-increasing amounts of circuitry into small spaces.

The Schottky diodes are RoHS compliant and have an operating temperature range of -40C to +125C, making them suitable for use in equipment that is utilised in harsh indoor and outdoor environments.
