Additional Details

The SMB10J12AHE3/52 is a bidirectional TVS diode with a standoff voltage of 12V. The 'A' in the part number signifies that it is a bidirectional device. Selecting a TVS diode with a standoff voltage slightly above the normal operating voltage of the protected circuit is essential to avoid interference during normal operation. The clamping voltage represents the maximum voltage the TVS diode will allow to pass through during a surge. The peak pulse current rating specifies the maximum surge current that the TVS diode can safely handle without being damaged. The device is generally designed to operate within a temperature range of -65°C to +150°C. The glass passivated chip junction construction ensures high reliability and performance. Solderable matte tin-plated leads facilitate easy and reliable soldering.
