8-channel Zener clamp for high-speed data-line protection
The Texas Instruments TPD8E003DQDR is an 8-channel unidirectional Zener-type ESD protection array in an 8-WSON (1.7x1.35) package.
10V clamping ceiling — what it buys the protected IC
With a clamping voltage of 10V at Ipp (2A, 8/20µs waveform), the TPD8E003DQDR holds the transient voltage below the absolute-maximum ratings of most 3.3V and 5V logic families. The 6V minimum breakdown ensures the device does not conduct during normal signal swings up to 5V. The 55W peak pulse power rating gives enough energy absorption for IEC 61000-4-2 level 4 ESD strikes without the device failing short.
