12/15/2003 - Royal Philips Electronics (NYSE: PHG, AEX: PHI) announced a new series of Electro Static Discharge (ESD) protection diodes designed to protect consumer and communications applications from ESD and other voltage induced transient pulses. With very low diode capacitance, ultra low leakage current and reverse stand voltages of 3.3V and 5.0V – all in ultra-small packages – the new ESD protection diodes provide designers of space-constrained applications an excellent option for protection of electrical equipment both at the system and component level.
Semiconductors are becoming smaller, denser and more complex, particularly in space-critical applications such as portable devices, which increases the semiconductors’ susceptibility to ESD pulses. With the ultra small package dimensions and integration of several protection diodes per device, Philips’ new ESD diode series is well suited for these space-critical applications, ranging from cellular handsets and accessories to computers and peripherals and audio / video equipment. Philips’ ESD protection diodes are designed to protect up to seven transmission or data lines from the damage caused by ESD pulses.
“With the introduction of the new ESD series of protection diodes, Philips is providing customers with superior ESD protection performance for all ESD sensitive applications by consuming minimum PCB space,” said Rochus Kraehe, application support manager for small-signal diodes at Philips Semiconductors. “We continue to drive innovation in the discrete diode arena while delivering products that meet our customers’ size and performance needs.”
In high-speed data rate or high frequency applications too much protection device parasitic capacitance causes unintentional signal attenuation. Offering a low device capacitance down to 16 pF, Philips’ new devices are ideal for ESD protection in these applications. The devices are also ideal for applications such as battery driven devices where power consumption is a key concern. With an ultra low leakage current down to 50 nA, the devices help lower overall power consumption in these applications.
Two new parts in the series – the PESD3V3L2UM and PESD5V0L2UM – are the first ESD protection devices on the market in the new leadless ultra small SOT883 surface mount package. The device footprint is 1.0 x 0.6 x 0.5 mm, providing customers with printed circuit board savings of 90% compared to the SOT23 package traditionally used for ESD protection diodes. The new series of diodes can withstand ESD pulses up to 20 kV and fulfills industry standard IEC 61000-4-2 (level 4), thus providing customers superior ESD protection performance.
The new ESD series of low capacitance diodes are available now in a range of configurations and packages:
