Load-current values are supplier selection references and depend on operating and cooling conditions. Confirm the final datasheet before design-in. Recommended heatsink reference sizes are not product, module or outline dimensions.
Application Notes
This product family is used in high-current industrial power supplies, AC/DC rectification systems, motor drives, welding equipment, battery charging equipment, industrial control equipment and power conversion systems.
Frequently Asked Questions
What information should I include in an inquiry?
Provide the model, required quantity, required voltage or voltage suffix, load type, application and destination country. The models on this page are quotation options within one product family.
How is voltage availability confirmed?
Voltage availability must be confirmed for the selected model against the final model-specific datasheet before quotation and design-in.
How should the heatsink requirement be confirmed?
Provide the operating current, load type, duty cycle, ambient temperature and cooling conditions. The listed heatsink sizes are selection references only; final thermal design must be confirmed for the application.
