Diode Arrays Procurement Notes

Verify the manufacturer origin carefully as Fairchild Semiconductor was acquired by onsemi. Confirm that the specific suffix TU corresponds to the tube packaging format required for your assembly process. Ensure the component meets RoHS compliance standards if mandated by your regional regulations. Cross-reference the datasheet revision date to confirm parameter consistency with your design requirements.

Diode Arrays Selection Notes

Select this component when high voltage blocking capability and moderate current handling are required in a through-hole package. The TO-3P form factor provides robust mechanical mounting and heat dissipation compared to smaller surface mount alternatives. Consider the 100 ns recovery time suitability for your specific switching frequency constraints.

Diode Arrays Part Context

This rectifier belongs to the FFA series of ultra-fast recovery diodes designed for high-efficiency power conversion. The series is characterized by low forward voltage drop and fast switching speeds, making it suitable for modern switch-mode power supplies. The transition from Fairchild to onsemi branding does not alter the fundamental electrical specifications of the device.

Diode Arrays Replacement Considerations

Publicly confirmed substitute part numbers include FFA10U120DN and FFA10U120DNTU from various distributors. Verify pinout compatibility and thermal resistance values before substitution.
