AP4N1R8CMT-A – N-Channel Power MOSFET – APEC

The AP4N1R8CMT-A is a 45 V N-channel enhancement-mode power MOSFET from APEC (Advanced Power Electronics Corp.) with an ultra-low on-resistance of 1.8 mΩ (max, V_GS = 10 V) in a PMPAK-5×6 surface-mount power package. Available for RFQ at Pacific Component Xchange.

The AP4N1R8CMT-A is an N-channel enhancement-mode power MOSFET manufactured by APEC (Advanced Power Electronics Corp.), a Taiwan-based specialist in discrete power MOSFETs and IGBTs. It is rated for a drain-source breakdown voltage of 45 V and features an ultra-low on-resistance of 1.8 mΩ (maximum at V_GS = 10 V), making it well suited to high-efficiency, low-conduction-loss power conversion. The device is supplied in APEC’s PMPAK-5×6 surface-mount power package, whose footprint is compatible with SO-8 while adding a backside heat sink and a lower profile.

Within APEC’s part-numbering convention, the “AP” prefix denotes the manufacturer, “N” denotes an N-channel device, the “1R8” code encodes the 1.8 mΩ on-resistance class, “CMT” identifies the PMPAK-5×6 package, and “-A” denotes a packaging/revision option. This part belongs to the same ultra-low-R_DS(on) MOSFET family as APEC’s related AP4N2R5 (2.55 mΩ) and AP3N1R8 (1.89 mΩ) series.
