Diode Arrays Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance requirements. The -N3 designation indicates the component is halogen-free and totally lead-free, whereas PbF denotes lead-free but not necessarily halogen-free status. Confirm that the TO-220AB package dimensions match the design constraints before finalizing procurement orders.

Diode Arrays Selection Notes

Select this component when high-frequency operation and low reverse leakage are required at elevated temperatures. Ensure the thermal management system can maintain the case temperature within limits defined by the 1.2 °C/W junction-to-case thermal resistance. Verify that the surge current capability of 2600 A aligns with the circuit's transient load conditions.

Diode Arrays Part Context

This part belongs to the VS-61CTQ series of center-tap Schottky rectifiers manufactured by Vishay Semiconductors. The series offers various voltage ratings including 35 V, 40 V, and 45 V options. All variants share the same 60 A total current rating and utilize the TO-220AB through-hole package for mounting.

Diode Arrays Replacement Considerations

Direct substitutes include other Vishay parts within the VS-61CTQ series such as VS-61CTQ035 or VS-61CTQ040 if lower voltage ratings are acceptable. Cross-manufacturer replacements must be verified for identical pinout configuration, current handling capacity, and thermal resistance specifications.
