Additional Details

The SSD355-TN98-LF typically comes in a small surface-mount package. Key technical specifications often include peak pulse power (PPP), reverse standoff voltage (VRWM), clamping voltage (VC), and junction capacitance (CJ). Refer to the manufacturer's datasheet for precise values, as these may vary depending on specific test conditions. It's crucial to verify the appropriate TVS diode based on the expected transient voltage and current levels in the application. Incorrectly sized TVS diodes may not provide adequate protection. Proper PCB layout is also essential for optimal TVS diode performance, including minimizing trace lengths and placing the diode close to the protected circuitry.
