  • General-purpose high-speed I/O ESD protection
  • Portable device connector ESD guard

The Texas Instruments TPD2E2U06DRLR is a dual-channel high-speed ESD protection diode providing IEC 61000-4-2 Level 4 protection (+/-25 kV contact, +/-30 kV air-gap) with only 1.5 pF of line capacitance. The 5.5V working voltage and 5.5A surge rating make it ideal for USB 2.0, LVDS, and I2C interface protection. The ultra-low capacitance and leakage current (10 nA max) ensure minimal impact on signal integrity. The compact 1.6 x 1.6 mm SOT-5X3 (DRL) package enables placement very close to connectors for maximum ESD protection effectiveness.

The TPD2E2U06DRLR uses silicon TVS (Transient Voltage Suppressor) diode technology in a uni-directional configuration. During normal operation, with signal voltages below the working voltage (5.5V), the TVS diodes present very high impedance (leakage less than 10 nA) and negligible capacitance (1.5 pF), allowing signals to pass without degradation. When an ESD event or voltage transient exceeds the breakdown voltage (6.5V minimum), the TVS diodes avalanche rapidly, creating a low-impedance path that shunts the surge current to ground. The device clamps the voltage to 9.7V, protecting downstream ICs. After the transient subsides, the device automatically returns to its high-impedance state.
