Milpitas, Calif. In a space-saving, chip-scale package suitable for mobile, digital consumer and computing applications, California Micro Devices Corp.'s newest member of its PicoGuard family of diode arrays, dubbed the CM1230, offers an ultra-low input capacitance of 0.8-pF per channel to preserve signal integrity in high-speed serial interfaces.
The CM1230 diode array features two integrated channels of electrostatic discharge protection (ESD) for high-speed serial interfaces, as well as RF signals in wireless handsets, USB 2.0 and serial ATA.
Each channel consists of two diodes, which steer the ESD current pulse to either the positive (VP) or negative (VN) supply rail. It also features a Zener diode connect across the VP/VN pins to protect against the Vcc rail against ESD strikes and eliminates the need for a bypass capacitor.
The CM1230 protects against ESD strikes up to ±8-kV contact or ±15-kV air discharge.
The CM1230 is available in two or four-channel CSP configurations. The CM1230-02 is sampling for 52 cents each in 1,000-unit quantity. The CM1230-04 will sample in the third quarter of this year. The CM1230 is offered with a RoHS-compliant, lead-free solution and can be ordered with an optional OptiGuard CSP coating.
