Automotive-grade ESD protection for 5.5V signal lines
It protects two unidirectional data lines against ESD and surge events, clamping transients to 12.4V typical at the peak pulse current.
Rated at 75W peak pulse power (8/20µs waveform), this diode absorbs the energy from ESD strikes and short-duration load-dump transients typical on automotive 12V and 24V power domains. The 5.5A peak pulse current capability (8/20µs) covers the IEC 61000-4-2 level 4 ESD requirement with margin. For sustained overvoltage events beyond the 8/20µs window, external series resistance or a higher-power TVS on the rail is needed — this part is sized for fast transients, not continuous fault.
Package and temperature — fits under-hood and exterior modules
Power line protection is built in, so the diode can be placed directly on a 5V or 3.3V supply rail without an external series element.
Listed as Active on TI's product status, the TPD2E2U06QDCKRQ1 remains in standard production with no announced last-time-buy or end-of-life notice. For new designs, this means no immediate obsolescence risk and stable lead times through authorized channels.
