Diode Arrays Procurement Notes

Verify the specific ordering suffix matches the required thermal and mechanical specifications. Confirm that the procurement channel provides original manufacturer documentation or traceable certificates of authenticity. Ensure the component lot date aligns with project requirements to avoid obsolescence risks during production runs.

Diode Arrays Selection Notes

Select this component when system design demands low conduction losses at high currents with a strict voltage budget. The 15 V rating suits low-side rectification where input voltages are minimal. Evaluate thermal management capabilities as the 35 A rating depends on maintaining the specified case temperature limit within the circuit layout.

Diode Arrays Part Context

This part belongs to the DSSK70 series of high-current Schottky rectifiers from IXYS. The series utilizes standard TO-247 packages to balance high power handling with ease of mounting. It serves as a specialized solution for modern power electronics where traditional PN junction diodes would introduce excessive heat due to higher forward voltage drops.

Diode Arrays Replacement Considerations

Direct substitutes include the DSSK70-008A for higher voltage ratings (80 V) and the DSP45-16A for lower current capacity (45 A). Verify pinout compatibility and thermal resistance parameters before swapping to ensure the replacement fits the existing PCB footprint and cooling infrastructure without derating performance.
