Diode Arrays Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation to confirm the correct package type and delivery mode. The datasheet indicates that the base part number corresponds to the M3 series, which denotes halogen-free, RoHS-compliant, commercial grade materials. Confirm the exact tube quantity and delivery specifications required for your procurement process.

Diode Arrays Selection Notes

Select this component when designing circuits requiring low forward voltage at high currents to minimize conduction losses. Ensure the application operates within the specified 150 °C junction temperature limit and accounts for the 1.8 °C/W thermal resistance. Verify that the 120 V reverse voltage rating provides sufficient margin for the circuit's peak reverse voltage conditions.

Diode Arrays Part Context

This component belongs to the V40120C family of dual high voltage TMBS rectifiers from Vishay. It is functionally similar to the VI40120C but utilizes a through-hole TO-220AB package instead of the surface-mount TO-262AA case. Both variants share identical electrical characteristics and are designed for robust performance in industrial power electronics.
