TPD1E10B06 is a bidirectional TVS with high ESD protection level. This device protects circuit from ESD strikes up to ±30 kV contact and ±30 kV air-gap specified in the IEC 61000-4-2 international standard. The device can also handle up to 6-A surge current (IEC61000-4-5 8/20 µs). The I/O capacitance of 12 pF supports a data rate up to 400 Mbps. This clamping device has a small dynamic resistance of 0.4 Ω typically, which makes the clamping voltage low when the device is actively protecting other circuits. For example, the clamping voltage is only 10 V when the device is taking 1-A transient current. The breakdown is bidirectional so that this protection device is a good fit for GPIO and especially audio lines which carry bidirectional signals. Low leakage allows the diode to conserve power when working below the V_RWM. The industrial temperature range of –40°C to 125°C makes this ESD device work at extensive temperatures in most environments. The 0402 package can fit into small electronic devices like mobile equipment and wearables whereas the SOD-523 package is good for industrial applications.
