Sample kit for ten TVS diodes

TDK has launched a sample kit with ten different types of ultra-compact TVS diodes with a mix of general purpose and high speed devices.

Five of the TVS diodes in the TDK B74999T9999M099 sample kit are part of 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 such as USB-C, Thunderbolt, HDMI, Display Port, MIPI, FireWire, DVI, S-ATA, or SWP/NFC.

The protection diodes are available in the chip scale packages WL-CSP01005 (400 x 200 μm) and WL-CSP0201 (600 x 300 μm).

The wide range of clamping voltages from 3.8 V to 27 V, the low leakage currents and the fast response time allow the TVS diodes to reliably protect diverse applications from electrostatic discharges.

The low profile of 100 µm for the 01005 and 150 µm for the 0201 are suitable for protecting smartphones, wireless earphones, smartwatches, and many other portable applications with limited space against ESD up to 25kV. The very low capacitances starting at 0.18 pF guarantees signal integrity even for the high-speed interfaces.
