GBO25-16NO1

Overview

The IXYS GBO25-16NO1 is a standard rectifier diode module featuring planar passivated chips and an epoxy casing compliant with UL 94V-0 standards. It offers a repetitive peak reverse voltage (VRRM) of 1600 V and supports a maximum average forward current of 25 A at 80°C case temperature. The device exhibits a low forward voltage drop, characterized by a threshold voltage of 0.89 V and a slope resistance of 12.2 mΩ. Designed for robust thermal performance, it provides a junction-to-case thermal resistance of 4.3 K/W per diode. The component utilizes a compact surface-mount package to facilitate easy mounting via a single screw.

Procurement Notes

Verify the specific ordering suffix NO1 against official IXYS documentation to confirm pinout configuration and packaging details. Ensure that the requested quantity aligns with manufacturer distribution channels. Confirm compliance with RoHS directives if required for the target application environment. Cross-reference datasheet revision dates to ensure access to the most recent technical specifications and mechanical drawings.

Selection Notes

Select this component when high voltage blocking capability up to 1600 V is required in a compact form factor. Evaluate the thermal management strategy based on the specified junction-to-case resistance of 4.3 K/W. Consider the 25 A average current rating relative to the expected operating temperature and heatsink capabilities. Verify that the forward voltage characteristics meet the efficiency targets of the rectification circuit design.
