7 Detailed Description

7.1 Overview

The TPD1E6B06 is a single-channel TVS diode for ESD protection in a small 0201 package. The TPD1E6B06 is rated to dissipate ESD strikes above the maximum level specified in the IEC 61000-4-2 international standard (Level 4), with ±15-kV contact discharge and ±15-kV air-gap ESD protection. The device has a back-to-back TVS diode configuration for bipolar or bidirectional signal support. The 6-pF line capacitance is suitable to provide transient voltage suppression circuit protection for a wide range of applications, supporting data rates up to
800 Mbps. Typical application interfaces for the TPD1E6B06 are audio lines (microphone, earphone, and speakerphone), SD interfacing, keypad or other buttons, as well as the VBUS and ID pins of USB ports.

7.3 Feature Description

The TPD1E6B06 is a single-channel TVS diode for ESD protection. This device provides circuit protection from ESD strikes up to ±15-kV contact and ±15-kV air-gap as specified in the IEC 61000-4-2 international standard. The device can also handle up to 3.8 A of surge current (IEC61000-4-5 8/20 μs). The TPD1E6B06 has 6 pF (typical) of capacitance which allows this device to support data rates up to 800 Mbps. Additionally, this low capacitance can even be necessary for an audio signal (for example, if a Class D amplifier is used). The TPD1E6B06 also has a small dynamic resistance of 0.55Ω (typical). This makes the clamping voltage low when it is protecting other circuits, which is crucial for protecting ICs during ESD events. 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 current allows the diode to conserve power when working below the VRWM. The industrial temperature range of –40°C to 125°C makes this ESD device to work well at extensive temperatures in most environments. The space-saving 0201 package is designed for small electronic devices like mobile phones and wearables.

7.4 Device Functional Modes

The TPD1E6B06 is a passive clamp that has low leakage during normal operation and activates whenever the voltage between pin 1 and pin 2 goes above VRWM or below -VRWM. During IEC ESD events, transient voltages as high as ±15 kV can be clamped between the two pins. When the voltages on the protected lines fall below the trigger voltage, the device reverts back to the low leakage passive state.
