TDK Expands Ultra-Low Voltage TVS Diode Portfolio for High-Speed Consumer Interfaces

TDK Corporation has expanded its ultra-low clamping voltage TVS diode lineup with three new models in the SD0201 series, tailored for high-speed consumer electronics interfaces. These TVS diodes offer compact protection for USB Type-C, HDMI, DisplayPort, and Thunderbolt connections in smartphones, laptops, tablets, wearables, and networking devices.

Each component comes in a 0201 chip-scale package (CSP), measuring just 0.58 x 0.28 x 0.15 mm (L x W x H) for space-constrained designs. Having working voltages of ±1 V, ±2 V, and ±3.6 V, the new TVS diodes safeguard sensitive circuits from electrostatic discharge (ESD) and transient surges. This means they meet IEC 61000-4-2 standards with ESD discharge robustness up to ±15 kV and support surge current handling up to 7 A, depending on the variant. Their symmetrical design enables bidirectional protection and thus flexible
