Descripción

Productos

The TPD2E001DRLR from Texas Instruments is a 2-channel transient voltage suppressor (TVS) ESD protection diode array designed to protect high-speed data lines from electrostatic discharge (ESD), electrical fast transients (EFT), and surge events. With a typical capacitance of only 0.5pF per channel, it is suitable for protecting high-speed interfaces such as USB 2.0, HDMI, and other differential signal pairs. The device is housed in a compact SOT-23-6 package and provides +/-15kV (HBM) ESD protection.

Características

  • Ultra-low capacitance (0.5pF) preserves signal integrity on high-speed lines
  • +/-15kV ESD protection (HBM) and +/-8kV (IEC contact)
  • Low clamping voltage (9.2V at 2A) protects downstream ICs
  • Bidirectional protection for differential signal pairs
  • Low dynamic resistance (0.6 Ohm) for effective transient suppression
  • SOT-23-6 compact footprint for space-constrained designs
  • IEC 61000-4-2 and IEC 61000-4-4 compliant

Aplicaciones

  • USB 2.0 data line ESD protection

  • General-purpose high-speed I/O protection
  • Portable electronics ESD protection
  • Industrial communication port protection

The TPD2E001DRLR from Texas Instruments is a specialized 2-channel ESD protection device designed for high-speed differential data lines. Its ultra-low channel capacitance of 0.5pF ensures minimal signal degradation on interfaces operating at high data rates, while the low clamping voltage of 9.2V at 2A effectively protects sensitive downstream ICs from ESD, EFT, and surge transients. The bidirectional protection topology supports both positive and negative transient events on differential signal pairs, making it ideal for USB, HDMI, and other high-speed protocols. The compact SOT-23-6 package enables placement close to connectors where protection is most effective.

The TPD2E001DRLR uses steering diodes and a central TVS device to clamp transient voltages on each protected channel. Under normal operation, the steering diodes are reverse-biased and present only the parasitic capacitance (0.5pF) to the signal path. When a positive transient exceeds the working voltage plus the forward diode drop, the upper steering diode conducts and directs the transient current through the central TVS device to ground. For negative transients, the lower steering diode conducts. The TVS device clamps the voltage at the protected node to a safe level (9.2V max at 2A), preventing damage to downstream circuitry. The low dynamic resistance of 0.6 Ohm ensures efficient energy diversion during fast ESD events.
