Diode Arrays Procurement Notes

Verify the specific suffix 'G' corresponds to the lead-free RoHS-compliant version when sourcing. Confirm that the SOT-523 package dimensions align with the target PCB land pattern. Ensure the selected supplier provides official datasheets confirming the 85 V rating and 155 mA current handling capabilities for the specific batch.

Diode Arrays Selection Notes

Select this component for designs requiring dual diodes in a minimal footprint where standard signal speeds are sufficient. The 85 V rating suits low-voltage systems, while the 155 mA current capacity supports moderate load requirements. Consider the 4 ns reverse recovery time for frequency-dependent applications. Evaluate thermal constraints as the small package limits heat dissipation compared to larger through-hole alternatives.

Diode Arrays Part Context

This part belongs to Comchip Technology's lineup of surface-mount diode arrays. It serves as a compact alternative to discrete single diodes, reducing board space usage. The SOT-523 package is widely used in mobile and wearable electronics where size reduction is critical. The product line emphasizes reliability and compliance with environmental standards for modern manufacturing processes.

Diode Arrays Replacement Considerations

Cross-reference with other SOT-523 dual diode arrays offering similar 85 V ratings and 155 mA currents. Verify pinout compatibility and reverse recovery characteristics before substitution. Ensure any replacement maintains the common cathode configuration to fit existing circuit layouts without redesign.
