Procurement Notes
Verify the specific suffix KDW against official MCC documentation to confirm the exact tape-and-reel packaging configuration and marking codes. Ensure that the ordering information matches the required quantity increments and lead times provided by authorized distributors. Cross-reference the datasheet revision date to guarantee compliance with current RoHS standards and material declarations before finalizing procurement orders.
Selection Notes
Select this component when a compact N-channel MOSFET with 20 V rating and 750 mA capability is required. The SOT-723 package offers space efficiency for dense PCB layouts. Consider the 380 mOhm on-resistance for low-loss switching applications. Verify that the gate threshold voltage characteristics align with the driving logic levels of the target circuit design.
Part Context
This part belongs to the SI3139KA series of small-signal MOSFETs designed for general-purpose switching. It shares similar electrical characteristics with other variants in the family but differs in packaging and specific manufacturing lot details. The device is intended for use in consumer electronics and industrial control boards requiring reliable performance in limited space constraints.
Replacement Considerations
Consult official substitution lists for compatible parts such as the SI3134K-TP if pinout compatibility is maintained. Verify that alternative components match the 20 V / 750 mA specifications and SOT-723 footprint. Do not assume interchangeability without confirming thermal and electrical parameter alignment.
