12/19/2002 - California Micro Devices (Nasdaq: CAMD) announced a new family of low-capacitance electrostatic discharge (ESD) protection devices that provide almost twice the ESD protection as competing products. The CM1209 family is the industry’s first low-capacitance ESD protection device to provide up to 15KV ESD contact protection, per the IEC61000-4-2 specification. Competing solutions typically offer only 8KV ESD contact protection. The CM1209, with only 6 pF of channel input capacitance, integrates up to 8 channels of ESD protection into a single device.
Target applications include high-speed data ports in PCs, set-top boxes, personal video recorders (PVRs), flat panel displays, and other consumer electronics that are likely to be exposed to ESD strikes. These ports include Digital Visual Interface (DVI), SCART, VGA, and full-speed (12 Mbps) USB ports.
Need for Higher Levels of ESD Protection
Typical end-user activities, such as connecting a digital camera to a PC or connecting a TV to a set-top box or PVR, can generate an ESD strike measured in thousands of volts. This can easily cause permanent damage to a PC or set top-box without adequate ESD protection.
“We designed the CM1209 family to provide the industry’s highest levels of ESD protection while minimizing capacitance, making them ideal for high-speed data ports typically found in PCs and consumer electronics,” stated Joe Salvador, director of marketing, computing products at California Micro Devices. “The CM1209 meets our customers’ requests for higher levels of ESD protection with the ability to withstand multiple ESD strikes and the low capacitance necessary for maintaining signal integrity on high-speed data ports.”
The CM1209 family provides 4, 6, or 8 integrated channels of 15KV contact ESD protection. Each ESD channel consists of a pair of diodes that steer the ESD current pulse to either the positive (Vp) or negative (Vn) supply rail. The CM1209 also integrates a Zener supply clamp which reduces ESD transients on the supply rail and eliminates the need for an external capacitor. The CM1209 products are offered in miniature MSOP and SOIC packages, making them ideal for portable electronics as well, and are pin-compatible with other popular ESD protection devices from California Micro Devices such as the CM1208-08, CM1210-08, and PACDN006. Key features include:
An important feature is these devices do not exhibit device degradation under repetitive ESD strikes that fall within their specification and can survive more than 1000 ESD events without degradation.
Pricing and Availability
The pricing of the CM1209-04, CM1209-06 and CM1209-08 per unit in 10,000 piece quantities are as follows:
