TDK Corporation (TSE:6762) introduces a sample kit (B74999T9999M099) consisting of ten different types of ultra-compact TVS diodes. Five of them belong to the general-purpose GP series, which protects against overvoltage on applications such as smartphones, tablets, notebooks, wearables, and network components; five others belong to the high-speed ULC series, which are tuned for particularly sensitive high-speed interfaces (e.g., USB-C, Thunderbolt, HDMI, Display Port, MIPI, FireWire, DVI, S-ATA, or SWP/NFC). These protection diodes are available in the ultra-compact packages WL-CSP01005 (400 x 200 μm) and WL-CSP0201 (600 x 300 μm).
Thanks to the wide range of clamping voltages from 3.8 V to 27 V, the low leakage currents and the fast response time, the TVS diodes reliably protect diverse applications from electrostatic discharges. Because of the ultra-low profile of 100 µm or 150 µm, they are an excellent solution to protect smartphones, wireless earphones, smartwatches, and many other portable applications with limited space against ESD. Due to the very low capacitances starting at 0.18 pF, signal integrity is guaranteed even with very demanding high-speed interfaces.
Main applications
- ESD protection for smartphones, tablets, notebooks, wearables and networking equipment
- ESD protection of high-speed interfaces such as USB-C, Thunderbolt, HDMI, Display Port, MIPI, FireWire, DVI, S-ATA, or SWP/NFC
Main features and benefits
- Low clamping voltages starting from 3.8 V at ITLP of 8 A
