Description

Product Overview

The TPD2E007DCKR from Texas Instruments is a 2-channel ESD protection diode array designed for AC-coupled and negative-rail data interfaces. In a 3-pin SC-70 package, it provides IEC 61000-4-2 Level 4 protection with 15pF I/O capacitance and back-to-back diode configuration for bidirectional signal lines.

Features

  • IEC 61000-4-2 Level 4 ESD protection
  • Back-to-back diode configuration for AC signals
  • Supports negative-going signals without clipping
  • 15pF max line-to-GND capacitance
  • 50nA low leakage current
  • Ultra-compact SC-70 3-pin package

Applications

  • Audio interface ESD protection
  • RS-232 and RS-485 transceiver protection
  • LVDS signal line protection
  • AC-coupled signal paths
  • Cell phone and PDA connector protection

The TPD2E007DCKR is a 2-channel ESD protection TVS diode array specifically designed for AC-coupled and negative-rail data interfaces from Texas Instruments. Unlike standard unidirectional ESD devices, its back-to-back diode configuration allows AC signals and negative-going waveforms to pass without clipping, making it ideal for audio, RS-232, RS-485, and LVDS interfaces. The device meets IEC 61000-4-2 Level 4 with +/-8kV contact and +/-15kV air-gap discharge ratings. The compact 3-pin SC-70 package minimizes board space in portable applications.

The TPD2E007 uses a back-to-back diode configuration on each channel, with two TVS diodes connected in series opposing between the signal line and ground. This arrangement presents a high impedance to both positive and negative signal swings within the working voltage range (up to 13V peak). When an ESD transient exceeds the breakdown voltage (14V min), the diode avalanches and clamps the voltage, shunting the transient energy to ground. The back-to-back topology ensures that neither positive nor negative signal excursions are clipped during normal operation.
