FET, MOSFET Arrays Procurement Notes

Verify the specific ordering suffix against official documentation to confirm exact packaging quantities and reel specifications. Ensure compliance with EU RoHS directives and UL-94 V-0 flammability standards required by the design. Confirm that the MLGA004-W-1111-RA package dimensions align with the target PCB land pattern and stencil requirements before finalizing procurement.

FET, MOSFET Arrays Selection Notes

Select this component when designing lithium-ion battery protection systems requiring a compact dual MOSFET solution with integrated gate resistors. Evaluate thermal performance based on the specific copper pad area available on the FR4 or ceramic substrate, as thermal resistance varies significantly between mounting conditions. Consider the 20 V breakdown voltage and current ratings relative to the maximum operating currents of the target battery cell configuration.
