TDK Launches Ultra‑Compact TVS Diodes for Robust IoT Protection

In a recent announcement, TDK Corp. details a new expansion to its family of bidirectional overvoltage protection for I/O interfaces with the introduction of high-power TVS diodes in ultra-small packages. They’re housed in 400 x 200 µm² (CSP01005) or 600 x 300 µm² (CSP0201) chip-scale packages (CSPs), with a package height of just 100 µm.

Built primarily as protection devices, these new diodes offer an operating voltage of 5 V and a response voltage of 6.8 V. The clamping voltages are 7.2 V at a peak pulse current of 8 A or 8 V at a peak pulse current of 16 A.

As mentioned earlier, this is a family of new products. The TVS diodes differ in their parasitic capacitances: Type SD0201SL-GP101 (ordering code B74121G0050M060) offers a capacitance of 12 pF, while the SD01005SL-GP101 type (B74111G0050M060) provides a capacitance value of 5 pF. Additional features include a short response time and low leakage current of 2 nA at 3.3 V.

Worth noting is that these protective devices are designed in accordance with IEC 61000-4-2 for an ESD contact discharge of up to 24 kV, exceeding standard requirements. They can withstand a high surge current load of up to 8 A according to IEC 61000-4-5 (8/20 µs), despite their low size.

In terms of application, TDK’s new TVS diodes can be used for IoT, smart home, and Industry 4.0 applications. With their small sizes, the devices can be used in wearables, smartphones, notebooks, tablets, smartwatches, and hearing aids.
