Diode Arrays Procurement Notes

Verify the specific suffix configuration when ordering. The standard production version lacks lead-free markings, while PbF variants are available. Confirm the exact voltage rating required, as the series includes both 35 V and 45 V options. Ensure the TO-220AB package matches the thermal management requirements of the target application design.

Diode Arrays Selection Notes

Select this component for applications requiring high-frequency operation and low forward voltage drop. The dual common-cathode configuration is suitable for center-tapped transformer circuits. Consider the thermal resistance values when designing heatsinking solutions to maintain junction temperatures within the specified operational limits during continuous conduction.
