Four-channel rail-to-rail steering TVS for HDMI
The Texas Instruments TPD4E05U06DQAR is a four-channel steering (rail-to-rail) TVS diode array for HDMI interfaces. It integrates four unidirectional channels in a single 10-UFDFN package.
14V clamping at 2.5A — what it means for HDMI protection
The maximum clamping voltage is 14V at a peak pulse current of 2.5A (8/20µs waveform). For HDMI 1.4 and 2.0 interfaces operating at 5V signaling, a 14V clamp provides enough headroom to absorb the IEC 61000-4-2 ESD strike without letting the transient break down the receiver's differential pair inputs. Peak pulse power handling of 40W covers the single-strike event typical in consumer ESD qualification. The 5.5V reverse standoff voltage means the device does not conduct during normal HDMI operation, where the TMDS lines swing between 2.25V and 3.3V common-mode.
Package and mounting — 10-USON (2.5x1) footprint
The small footprint suits designs where PCB real estate is tight, such as HDMI 2.0 receptacles on compact media players or laptop mainboards. The supplier device package is 10-USON (2.5x1), identical to the 10-UFDFN case code.
