It is specifically designed for CAN (Controller Area Network) bus protection per ISO 11898. The device provides: (1) Bidirectional clamping: both positive and negative ESD events are clamped, protecting the CAN transceiver on both lines; (2) Low capacitance (8pF typical per line to ground), ensuring minimal signal integrity impact on high-speed CAN (up to 1Mbps); (3) ESD protection per IEC 61000-4-2: +\/-15kV contact discharge, +\/-25kV air discharge; (4) EFT protection per IEC 61000-4-4: 40A (5\/50ns); (5) Surge protection per IEC 61000-4-5: 3.5A (8\/20us). The working voltage is 24V, meaning the diode leakage is negligible below 24V (important because CAN bus can have common-mode voltages up to 12V per the standard). The breakdown voltage is 28.5V minimum, and the clamping voltage at IPP=3.5A is 40V maximum. The low capacitance (8pF) ensures the total bus capacitance budget per the CAN specification (typically 10pF per node, with 8pF from ESD protection this is tight but acceptable for short stubs). The SOT-23-3 package provides a compact footprint near the CAN connector. The device should be placed as close as possible to the bus connector, before the CAN transceiver, to divert ESD energy before it reaches the transceiver. The -LT1G suffix specifies SOT-23-3, tape-and-reel, lead-free.","pin_description":"
