Diotec Semiconductor Introduces Rectifier Diodes, ER1D-AQ. With the help of solar panels, one can travel on the water even more independently and improve safety at sea. Electronic systems play an important role in navigation, steering, radar detection, marine communications, and everything from climate control to marker lights. Like in a car or truck, these electronics are supplied from a 12 V or 24 V battery, charged from the combustion engine. But what if that engine fails? Then the battery will be discharged quite quickly, which is a nightmare when you are in the middle of the Pacific Ocean. It is good to know that the solar panels can still charge the battery in such a case.

The ER1D-AQ by Diotec Semiconductor is a superfast recovery rectifier, qualified to AEC-Q101 and assembled in a DO-214AC/SMA package. It is an output rectifier in a maritime DC/DC converter, transforming the 24 V battery level to the 5 V required from the onboard electronics. Its superfast switching time reduces power losses, the 200 V of reverse voltage provides a high safety margin, and the qualification according to AEC-Q101 ensures outstanding reliability.
