Selection Guidance

When selecting this rectifier, verify that the peak reverse voltage and average forward current meet your circuit requirements. The low forward voltage is particularly beneficial in battery-powered or high-efficiency designs. For detailed thermal and electrical characteristics, refer to the official datasheet. Some parameters such as junction-to-ambient thermal resistance are to be verified based on specific PCB layout and operating conditions.
