Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and delivery mode. Confirm compliance requirements such as RoHS status and halogen-free material categorization prior to procurement. Ensure thermal management designs account for the specific thermal resistance values associated with the TO-262AA package configuration.

Diode Arrays Selection Notes

Select this component when a low-profile surface-mount solution is required for high-frequency rectification. The TO-262AA package offers a compact footprint suitable for space-constrained designs. Evaluate the thermal performance based on the junction-to-case and junction-to-ambient resistance values provided in the datasheet to ensure reliable operation at the intended load currents.

Diode Arrays Part Context

This part belongs to the V20M120C series of dual high-voltage Trench MOS Barrier Schottky rectifiers. The VI20M120C designation specifically identifies the version packaged in the TO-262AA form factor, distinguishing it from the through-hole TO-220AB variant (V20M120C). Both variants share identical electrical characteristics but differ in mechanical mounting and thermal dissipation properties.

Diode Arrays Replacement Considerations

The V20M120C-M3/4W serves as the direct through-hole equivalent within the same product family. When substituting, verify that the target application can accommodate the mechanical differences between the TO-262AA surface-mount package and alternative packages.
