No official successor or cross-reference has been issued — the part is the current production choice for this Zener-type ESD suppressor in the SOD-523 footprint.
6V standoff — fits 5V rail protection
With a 6V max reverse standoff voltage, this Zener-type ESD suppressor sits above a 5V supply rail and triggers breakdown at 6.8V min. The clamping ceiling is 20.5V at the peak pulse current of 8.8A (8/20µs waveform), which keeps the transient below the typical 30V absolute-max of downstream 5V logic.
181W peak pulse — energy budget for industrial transients
Rated at 181W peak pulse power, the ESD5Z6.0T1G handles the energy from ESD strikes and short inductive spikes common in general-purpose industrial and consumer boards. The 70pF capacitance at 1MHz keeps signal integrity intact on low-speed data lines and I/O ports.
SOD-523 — small footprint for dense layouts
Housed in the SC-79 / SOD-523 surface-mount package, this single-channel unidirectional suppressor fits tight PCB real estate.
