Additional Details

The CG32.5L has a standoff voltage of 32.5V. This is the maximum voltage that can be continuously applied without triggering the TVS diode. Its breakdown voltage is typically around 36.1V, and it clamps the voltage to a specific value during a surge event, protecting downstream components. The peak pulse power is specified in the datasheet and indicates the maximum surge power the device can handle. The operating temperature range is typically -55°C to +150°C. The package is typically DO-214AC (SMA). It's crucial to select a TVS diode with appropriate standoff voltage, clamping voltage, and surge capability for the specific application. Proper PCB layout and grounding are essential for optimal performance. Refer to the Littelfuse datasheet for precise specifications and application notes.
