Milpitas, Calif. California Micro Devices (CMD) has unveiled XtremeESD, a family of protection devices developed with a new architecture designed to meet the industry's most challenging electrostatic discharge (ESD) requirements. The first XtremeESD product, the CM1231-02SO, uses CMD's new Picoguard XP architecture.
The Picoguard XP uses a double clamping architecture that integrates multiple stages of ESD protection into a single device. It provides protection for sensitive high-speed ICs by significantly reducing the clamping voltage and the amount of residual current that passes through to the protected ASIC, while maintaining the signal integrity of the high-speed data, and achieving significantly better performance than the best ESD diode arrays on the market, according to CMD.
The PicoGuard XP architecture uses a unique dual-stage design that places two ESD devices and a resistor in series within the same package. The first ESD circuit absorbs the largest portion of the strike, while the second provides additional clamping and a secondary shunt path to steer current away from the system IC being protected. According to CMD, the CM1231 provides significant improvements compared to the best protection devices currently available including 40 percent reduction in peak clamping voltage, 40 percent reduction in peak residual current, and greater than 65 percent reduction in total power reaching the ASIC.
In conjunction with the introduction of the CM1231, CMD has also launched a new web site that provides information about ESD protection for designers of personal computer and digital consumer electronics applications. The XtremeESD site contains technical white papers, product specifications, articles and presentations on various ESD protection topics.
Pricing: $0.38 each in quantities of 1,000
Availability: Currently in full production, the CM1231-02S0 is available in a SOT23-6 package to protect two data lines.
