TVS diodes shield consumer electronics interfaces

TDK has added three new models to its SD0201 series of TVS diodes for USB Type-C, HDMI, DisplayPort, and Thunderbolt connections. They protect sensitive circuits in smartphones, laptops, wearables, and networking devices from ESD and transient surges.

Each component comes in a 0201 chip-scale package with dimensions of 0.58×0.28×0.15 mm, suited for space-constrained designs. With working voltages of ±1 V, ±2 V, and ±3.6 V, the TVS diodes meet the IEC 61000-4-2 standard for ESD robustness up to ±15 kV and handle surge currents up to 7 A, depending on the variant. Their symmetrical design enables bidirectional protection for I/O interfaces, and they feature low leakage current with dynamic resistance down to 0.16 Ω.

The three new devices in the SD0201 series differ in their DC working voltages and parasitic capacitances:

• SD0201SL-S1-ULC101 (B74121U1036M060): ±3.6 V, 0.65 pF
• SD0201-S2-ULC105 (B74121U1020M060): ±2 V, 0.7 pF
• SD0201SL-S1-ULC104 (B74121U2010M060): ±1 V, 0.15 pF
