FST160100

Diode Arrays Overview

The FST160100 is a Schottky Barrier Rectifier manufactured by Microsemi Corporation. It features a maximum repetitive peak reverse voltage of 100V and an average forward current rating of 80A per package. The device utilizes a TO-249AA module housing with nickel-plated copper pins and baseplate. Key electrical characteristics include a maximum instantaneous forward voltage of 0.96V at 80A and a maximum non-repetitive peak forward surge current of 1200A. The junction-to-case thermal resistance is specified at 0.5°C/W, supporting operation within a junction temperature range of -55°C to 175°C.

Diode Arrays Procurement Notes

Verify the specific suffix configuration required for your circuit topology before ordering. The standard designation implies a common cathode arrangement; append 'A' for common anode or 'D' for doubler configurations as needed. Confirm compliance with RoHS directives if restricted materials are prohibited in your assembly process. Ensure mounting hardware meets the specified torque requirements to maintain thermal performance.

Diode Arrays Selection Notes

Select this component when low forward voltage drop and fast recovery are critical for efficiency. Evaluate the thermal management strategy against the 0.5°C/W junction-to-case resistance to ensure case temperatures remain within limits during continuous operation. Consider the 1200A surge capability for handling transient load spikes without device failure.

Diode Arrays Part Context

This part belongs to the FST160 series of Schottky Powermod devices from Microsemi. The series includes variants with different reverse voltage ratings, such as the FST16090 which offers a 90V rating. These modules are designed for high-current industrial applications requiring robust packaging and reliable semiconductor performance under demanding electrical conditions.

Diode Arrays Replacement Considerations

Direct substitutes must match the 80A average forward current, 100V reverse voltage, and TO-249AA mechanical footprint. Verify that alternative Schottky rectifiers provide comparable junction-to-case thermal resistance and surge current capabilities to maintain system reliability.

Diode Arrays FAQ

What does the suffix 'A' indicate for this part number?

Appending the suffix 'A' changes the internal configuration to a Common Anode setup.

Is the baseplate electrically connected to any terminal?

No, the nickel-plated copper baseplate is electrically isolated from the internal terminals.

What is the maximum operating junction temperature?

The device supports an operating junction temperature range up to 175°C.
