CSPESD304 Description

Short technical summary and product information.

The CSPESD304 is a quad ESD transient voltage suppression diode array designed to protect sensitive electronic components from electrostatic discharge (ESD). Each diode in the array provides ±15 kV ESD protection, meeting the IEC 61000-4-2 Level 4 standard for contact discharge. It also offers protection for contact discharges to greater than ±30 kV based on the MIL-STD-883 (Method 3015) Human Body Model (HBM) specification.

This device is particularly suitable for portable electronics due to its small, low-profile Chip Scale Package (CSP) with a 5-bump footprint measuring 0.960 mm x 1.330 mm. The CSP package features extremely low lead inductance, which enhances ESD protection performance. The CSPESD304 is Pb-free and RoHS compliant.

Applications include ESD protection for sensitive electronic equipment, I/O ports, keypads, and button circuitry in portable devices such as wireless handsets, handheld PCs, PDAs, MP3 players, digital camcorders, notebooks, and desktop PCs. It can also be used for EMI filtering when combined with external series resistance.
