Diode Arrays Procurement Notes

Verify the specific suffix 'PB' against the manufacturer's official datasheet to confirm lead-free compliance and packaging type. Ensure the ordering part number matches the exact voltage and current ratings required for the target application circuit design.

Diode Arrays Selection Notes

Select this component when a common cathode dual diode configuration is required for space-constrained designs. The TO-220AB package provides adequate thermal dissipation for moderate power levels. Verify that the 100V rating exceeds the maximum reverse voltage stress in the intended circuit topology.

Diode Arrays Part Context

This component belongs to IXYS's discrete diode portfolio, specifically within the Schottky rectifier category. It serves as a solid-state alternative to traditional PN-junction diodes where lower switching losses and reduced heat generation are critical performance factors for power conversion systems.

Diode Arrays Replacement Considerations

Direct replacements must match the 100V/40A specification and TO-220AB-3 footprint. Verify pinout compatibility and thermal resistance values before substitution.
