7 Detailed Description

7.1 Overview

The TPD2E1B06 is a bidirectional, low-capacitance, two-channel ESD clamping device. It has more than IEC 61000-4-2 Level 4 ESD Rating. The low IO capacitance makes the device a good fit for a wide range of data speeds. Common applications include USB 2.0, LVDS, and I2C.

7.3 Feature Description

The TPD2E1B06 device provides robust system level IEC protection. This device protects circuit from ESD strikes up to ±10-kV contact and ±15-kV air-gap specified in the IEC 61000-4-2 level 4. It also handles up to
2.5-A surge current (IEC61000-4-5 8/20 µs). The I/O capacitance of 0.85 pF supports high data rates. The device has a small dynamic resistance of 0.9 Ω, making clamping voltage low when the device is actively protecting other circuits. With low capacitance and dynamic resistance, the TPD2E1B06 is a good fit for interfaces like USB 2.0, LVDS, and I2C. The breakdown is bidirectional so that this protection device is especially good for bidirectional signals like audio lines. Low leakage allows the diode to conserve power when working below the VRWM. The temperature range of –40°C to 125°C makes this ESD device work at extensive temperatures in most environments.

7.4 Device Functional Modes

The TPD2E1B06 is a passive clamp that has low leakage during normal operation when the voltage across each channel is below VRWM and activates when the it goes above VBR. During IEC ESD events, transient voltages will be clamped. When the voltages on the protected lines fall below the trigger voltage, the device reverts back to the low-leakage passive state.
