Additional Details

The SMCJ5.0CAHE3/9AT is a bidirectional TVS, offering symmetrical protection. It has a standoff voltage of 5V. It's crucial to choose a TVS diode with a standoff voltage that is appropriately higher than the normal operating voltage of the protected circuit to avoid any impact on normal operation. The clamping voltage is an important parameter; it indicates the maximum voltage that the TVS diode will allow to pass through to the protected circuit during a surge event. The peak pulse current rating specifies the maximum surge current that the TVS diode can safely handle. Operating temperature range is typically -65°C to +150°C. The device’s construction utilizes glass passivated chip junction technology for enhanced reliability and performance. It offers solderable matte tin plated leads.
