ESD protection device boasts 0.35pF capacitance

California Micro Devices (CMD) has launched the PicoGuard CM1227, an ultralow-capacitance ESD device for the latest digital consumer and computer applications.

The CM1227 provides four channels of ±15kV of contact ESD protection, exceeding IEC61000-4-2 level 4 standards. Latest digital consumer and computing applications such as digital TVs, STBs, PCs and PC peripherals are increasingly adopting advanced high-speed serial interfaces such as USB 3.0, MIPI, eSATA, DisplayPort and FireWire. These low-voltage signaling interfaces require very fast rise and fall times not normally achievable with ESD protection devices installed on the signal line because of capacitive loading. The CM1227, with a low capacitance level of 0.35pF, delivers both robust ESD protection and high signal integrity.

Based on CMD's PicoGuard line of ESD protection products, the CM1227 significant space and cost savings to deliver enhanced customer value for today's most advanced digital consumer and PC designs.

The device also features ESD protection for transition minimized differential signaling channels and channel input capacitance matching of 0.02pF (typ), ideal for differential signals. The CM1227 offers minimal capacitance change over operating voltage range. Each I/O pin of the CM1227 can withstand over 1000 ESD strikes.

The CM1227 is available in a 10-pin microUDFN (2.5mm X 1.0mm) RoHS-compliant (Pb-free) package. Samples are available now and are priced at $0.30 each in quantities of 1,000 units. Production is scheduled for Q1 10.
