VS-80CNQ045APBF

Diode Arrays Overview

The VS-80CNQ045APBF is a Schottky rectifier module manufactured by Vishay General Semiconductor - Diodes Division. It features a dual common cathode configuration housed in a TO-244AB package designed for stud mounting. The device supports a maximum repetitive reverse voltage of 45 V and an average forward current of 80 A per diode. Key electrical characteristics include a typical forward voltage of 660 mV at 80 A, a maximum reverse leakage current of 5 mA at 45 V, and a peak forward surge current rating of 5.8 kA. The junction temperature range extends from -55°C to +150°C.

Diode Arrays Procurement Notes

Verify the specific suffix 'PBF' confirms lead-free compliance with RoHS standards. Confirm the package type matches the required mounting hardware. Check for obsolescence status as Vishay frequently updates its diode portfolio. Ensure the thermal interface material is compatible with the stud mount surface. Validate that the 45 V rating meets the circuit's peak inverse voltage requirements.

Diode Arrays Selection Notes

Select this component when a robust, high-current Schottky solution is needed for low-voltage, high-amperage circuits. The TO-244AB package offers superior thermal performance compared to standard through-hole packages. Consider the 5.8 kA surge capability for inductive load protection. Evaluate the 660 mV forward voltage against system efficiency targets. Ensure the mounting torque specifications are strictly followed to maintain thermal contact integrity.
