It contains two bi-directional TVS (Transient Voltage Suppressor) diodes in a single package, each connected between a bus line (CANH\/CANL or LIN) and ground. In normal operation, the bus lines are below the 24V clamping threshold, and the diodes present only 3.5pF capacitance per line to ground, which is low enough for CAN data rates up to 1Mbps without signal degradation. When an ESD event or transient exceeds the breakdown voltage (approximately 26V), the TVS diode conducts and clamps the voltage to approximately 38V at 1A (peak pulse current 5A). The bi-directional design protects against both positive and negative transients. The device is specifically designed for CAN 2.0 and LIN bus protocols where the normal differential voltage between CANH and CANL is 0-2V and common-mode range is -2V to +7V. The 24V VRWM is chosen to be above the maximum CAN bus fault voltage (typically 18-24V) while clamping before the 40V absolute maximum of CAN transceivers. The SZ prefix indicates automotive AEC-Q101 qualified. The -LT1G suffix specifies SOT-23-3, tape-and-reel.","pin_description":"
