TDK’s sample kit (B74999T9999M099) consists of ten different types of ultra-compact transient voltage suppressor (TVS) diodes. Five belong to the general-purpose GP series, which protects against overvoltage on applications such as smartphones, tablets, notebooks, wearables, and network components; the other five 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).
