TPSMC43CA

The TPSMC43CA is a TVS-Diode designed to provide superior overvoltage protection for sensitive electronic equipment. This device protects against high voltages caused by load dump, inductive kickback on high-side switches, and ESD. It offers industry-leading surge current capabilities with transient current up to 37A with no external fusing.

The TPSMC43CA features a bidirectional design which can handle both positive and negative transient events. It consists of a diode array along with a resettable Bidirectional Transil element, which limits transient voltage to a rating of 43V. This diode is RoHS-compliant and lead-free, and meets the JEDEC EIA/JESD22-A114F standard.

The typical applications of the TPSMC43CA include overvoltage and abnormal voltage protection for automotive infotainment systems, navigation systems, exterior lighting, and high-end consumer electronics. This diode can also be used for DC-DC converters, power management/control, and automotive Inverter power supply applications.

The TPSMC43CA diode works by clamping the voltage on the output when it is subjected to a large voltage surge. This is done by using a diode array and a resettable Bidirectional Transil element. When a voltage surge occurs, an electric field across the diode breaks down the insulating material in the device, allowing current to flow across the diode, thus clamps the voltage on the output. Since the bidirectional Transil element is resettable, it will reset itself after the surge is over, allowing the normal operation to resume.

The TPSMC43CA device offers superior protection performance, with an overvoltage withstand capability up to 40V and a surge capability up to 37A. It offers improved testability performance with a fail safe mechanism for easy debugging and a wide fail safe test window for optimized testing. The diode also features an internal ESD protection, and an open circuit voltage protection mechanism for improved system reliability. The device is also dendrite-free and offers greater immunity to short circuits.

The TPSMC43CA diode is designed for mounting in the TO-263AA package. It features high surge current rating up to 37A with no external fusing, which offers improved efficiency and higher performance. The low ESR of the device ensures fast switching and stable operation, and the high surge current rating ensures long-term reliability of the system.

In summary, the TPSMC43CA diode provides superior protection against abnormal voltages and transients, with its overvoltage withstand capability up to 40V and surge capability up to 37A. It offers improved system reliability with dendrite-free performance, internal ESD protection, and open circuit voltage protection mechanism. This device can be used in applications such as automotive infotainment systems, navigation systems, exterior lighting, high-end consumer electronics, and DC-DC converters.
