Procurement Notes
Verify the specific suffix 'AL' against the manufacturer's official datasheet to confirm exact electrical tolerances and pinout configurations. Ensure the component matches the required TO-252 footprint and thermal pad specifications for the target PCB layout. Confirm RoHS compliance status through the supplier's certificate of conformity prior to integration into production lines.
Selection Notes
Select this component when a low-voltage N-channel MOSFET with moderate current handling is required in a compact surface-mount form factor. Evaluate the thermal resistance characteristics relative to the available heatsinking or copper area on the printed circuit board. Compare the gate charge and threshold voltage parameters against the driving circuit capabilities to ensure reliable turn-on and turn-off transitions under expected load conditions.
Part Context
This part belongs to the discrete semiconductor product category, specifically single field-effect transistors. Alpha & Omega Semiconductor Inc. produces this device as part of their standard MOSFET portfolio designed for general-purpose power switching. The TO-252 package is widely utilized in consumer electronics and industrial equipment where space constraints necessitate surface-mount technology.
Replacement Considerations
Publicly confirmed substitute part numbers are not provided in the available documentation. Verify compatibility with alternative devices by matching the 40V Vds rating, 12A Id current capacity, and TO-252 package dimensions. Cross-reference gate charge and on-resistance values to ensure equivalent switching performance in the specific application circuit.
