CM1624-08DE

The CM1624-08DE is a TVS Diode with EMI filter and ESD protection. It is a combination EMI filter and line termination device with integrated TVS diodes for use on multimedia card interfaces. This state-of-the-art device utilizes solid-state, silicon-avalanche technology for superior clamping performance and DC electrical characteristics. The device has been optimized for protection of T-Flash/microSD interfaces in cellular phones and other portable electronics. It consists of six circuits that include series impedance matching resistors and pull-up resistors as required by the SD specification. Termination resistor value of 40Ω is provided on the SDData0, SDData1, SDData2, SDData3, CMD and CLK lines. Pull-up resistors of 25kΩ are included on the SDData0, SDData1, SDData2, SDData3 and CMD lines as well. It may be configured for devices operating in SD or SPI mode.

• ±15kV ESD protection (IEC 61000-4-2, contact discharge)
• Significant attenuation of noise in the 700MHz bands
• Mates perfectly with the most popular micro SD interfaces
• provides robust, fast-acting transient voltage suppression to protect ESD sensitive devices
• Critical for compliance for emerging protocols such as LTE and 4G
• Solid-state technology
• -40 to 85°C Operating temperature range
