Additional Details

The TPSMC39A-E3/57T has a standoff voltage of 39V, meaning it will not conduct under normal operating conditions up to 39V. When the voltage exceeds this level, the TVS diode starts to conduct and clamps the voltage to protect downstream components. It is designed for surface mount applications and offers a low profile. The 'E3' suffix indicates RoHS compliance, and the '/57T' likely refers to specific testing or packaging variations. The device is used in applications where protection against transient voltage surges is critical for ensuring system reliability and longevity.
