Silicon ESD Protection Devices SESD Series

Silicon ESD Protection Devices SESD Series

Littelfuse's silicon ESD (SESD) devices help provide protection and improve reliability for applications including consumer, portable, and mobile electronics. The 0402- and 0201-sized devices have low-capacitance of 0.10 pF for bi-directional devices and 0.20 pF for uni-directional devices with low-insertion loss. This helps provide protection for high-speed data signals. The single-channel SESD devices provide robust ESD protection with 20 kV contacts and air discharge ratings per IEC61000 4-2 standard. The ultra-low capacitance enables signal integrity for today’s highest speed interfaces including USB 3.0/2.0, HDMI, eSATA, DisplayPort, and Thunderbolt.

Littelfuse offers the single-channel devices in uni-directional and bidirectional configurations. Bidirectional devices offer the lowest capacitance and insertion loss, allow placement on the PCB without orientation constraint, and do not clip signals that swing below ground. Unidirectional devices offer a low negative breakover voltage and help provide protection for high-speed digital interfaces. The 0201-sized XDFN small footprint, measuring a mere 0.6 mm x 0.3 mm x 0.31 mm, offers designers placement flexibility in space-constrained applications.
