Working Principle

The SBR2045CTFP is designed to provide effective overvoltage protection and reverse polarity protection in a variety of circuit configurations. The two bypass diodes and two zener diodes can be used in combination to provide the desired protection. In normal operation, the two bypass diodes conduct, redirecting the majority of the current around the zener diodes. As the zener diodes reach their breakdown voltage, the current is diverted through them and the excess voltage is dissipated. The zener diodes can be adjusted to ensure that the voltage remains within a desired range, providing the required proteciton.When exposed to a reverse polarity event, the two bypass diodes become non-conductive, diverting the current away from the sensitive components and into the diodes. The bypass diodes will safely dissipate the excess current and reduce the direct effect of the reverse polarity on the circuit.

Conclusion

The SBR2045CTFP provides a simple yet effective solution for overvoltage protection and reverse polarity protection in a variety of applications. Its two-pin configuration, wide operating range, and adjustable zener diodes make the SBR2045CTFP an ideal option for automotive and electronic circuits, industrial controls, consumer electronics, and telecommunications. The effective and reliable protection provided by this device makes it a cost-effective solution for these applications.
