Diode Arrays Procurement Notes

Verify the specific ordering suffix when sourcing components. The -N3 designation indicates the part is halogen-free, RoHS compliant, and totally lead-free, whereas PbF variants are also available. Confirm package dimensions against TO-220AB standards and ensure thermal management aligns with the specified junction-to-case thermal resistance values provided in the datasheet.

Diode Arrays Selection Notes

Select this component for applications requiring high surge current handling and low conduction losses at elevated temperatures. Ensure the circuit design accommodates the 30 V reverse voltage rating and that the thermal solution maintains the junction temperature within the 150 °C limit. Verify compatibility with the TO-220AB mounting requirements and torque specifications.

Diode Arrays Part Context

This device belongs to the Vishay Schottky rectifier family, specifically optimized for low forward voltage characteristics. It is housed in a TO-220AB package, which facilitates efficient heat dissipation through the base plate. The dual anode common cathode layout allows for use in full-wave rectification or center-tapped transformer configurations.

Diode Arrays FAQ

What is the maximum non-repetitive surge current rating?

The maximum peak one-cycle non-repetitive surge current is 1100 A for a 5 μs sine pulse or 360 A for a 10 ms sine pulse.

How does the forward voltage drop vary with temperature?

The forward voltage drop decreases as temperature increases; it is rated at 0.48 V at 25 °C and drops to 0.38 V at 125 °C for a 20 A forward current.

Is the device qualified for automotive applications?

The datasheet specifies qualification according to JEDEC-JESD47 standards but does not explicitly state AEC-Q101 automotive qualification for this specific part number.
