Every spec below is cited to the manufacturer datasheet. Pick your exact ordering code, compare the closest alternatives, then ask the assistant what it means for your design.
What the ESDA25L family does
The ESDAxxL family comprises dual unidirectional transil arrays designed for ESD protection on data and transmission lines. Variants include the ESDA5V3L, ESDA6V1L, ESDA14V2L, and ESDA25L, covering stand-off voltages from 5.3V to 25V. These components withstand up to 25kV ESD surges and handle 300W peak pulse power. They feature low leakage current under 20mA and a clamping voltage determined by dynamic resistance. The devices are suitable for high-density boards and specifically recommended for protecting RS232 I/O ports in computers, printers, and communication systems against transient overvoltage.
