Diode Arrays Procurement Notes

Verify the specific suffix designation when ordering, as 'A' indicates a common anode configuration and 'D' denotes a doubler topology. Confirm RoHS compliance status and ensure mounting torque specifications are strictly adhered to during installation. Validate that the selected variant matches the required electrical isolation and thermal management requirements for the target application environment.

Diode Arrays Selection Notes

Select this component based on the 100 V reverse voltage rating and 60 A per leg current capability. Consider the 0.6°C/W junction-to-case thermal resistance for heatsink design. Evaluate the need for common anode or doubler configurations by checking the appropriate suffix. Ensure the operating junction temperature range aligns with system thermal constraints.

Diode Arrays Part Context

This device belongs to the FST6080-FST60100 series of Schottky Powermods manufactured by Microsemi. These components utilize silicon Schottky barrier technology to provide low forward voltage drops and fast switching characteristics. The series is designed for high-reliability applications requiring robust surge handling and efficient thermal dissipation through an isolated baseplate.

Diode Arrays Replacement Considerations

Direct substitutes include the FST6080 and FST6090 variants within the same series, which share identical physical dimensions and thermal characteristics but differ in their repetitive peak reverse voltage ratings of 80 V and 90 V respectively.

Diode Arrays FAQ

What is the function of the electrically isolated baseplate?

The electrically isolated baseplate allows the device to be mounted directly to a heatsink without requiring an additional insulating layer, simplifying thermal management while maintaining electrical safety.

How does the suffix affect the internal configuration?

Adding the suffix 'A' configures the device as a common anode rectifier, while adding 'D' sets it up as a doubler configuration, altering the internal connection topology of the diode elements.

What is the maximum surge current rating?

The maximum non-repetitive peak forward surge current is rated at 1200 Amps under specified pulse test conditions.
