■ Frequently Asked Questions (FAQ)
What are the primary specifications of WSP4812 series MOSFETs?
The WSP4812 series (including WSP4882, WSP4886, and WSP4884) features a Drain-Source Voltage (VDS) of 30V, a Gate-Source Voltage (VGS) of ±20V, continuous current ratings up to 8.8A, low RDS(ON) resistance down to 18mΩ (typ) @ 10V, and a Dual N-channel configuration inside a standard SOP-8L package.
In what products can these Dual N-channel MOSFETs be applied?
These MOSFETs are widely applied in modern power management applications including E-cigarettes, wireless chargers, electric motors, drones, medical equipment, car chargers, system controllers, digital products, small household appliances, and other consumer electronics.
What is the standard packaging format for these MOSFET parts?
All models in this series—namely the WSP4812, WSP4882, WSP4886, and WSP4884—are packaged in the SOP-8L format, which supports stable surface mount technology (SMT) and efficient space utilization on PCBs.
What are the compatible replacements for WSP4882?
The WSP4882 can be cross-referenced and replaced by standard industry models such as AOS AO4800, Fairchild FDS6612A, Vishay Si4214DDY, ST STS8DNF3LL, IR PV628BA, and Sinopower SM4804DSK, among other listed configurations.
What is the difference in RDS(ON) between these MOSFETs?
While all share similar voltage and structural profiles, they differ slightly in RDS(ON). For example, WSP4812 and WSP4882 show typical values of 20mΩ @10V (Max 26mΩ), while WSP4886 is lower at typical 18mΩ @10V (Max 24mΩ), and WSP4884 has a typical value of 18.5mΩ @10V (Max 23mΩ).
Are there equivalent cross-reference parts for the WSP4886?
Yes, the WSP4886 is compatible with equivalent components like AOS AO4842 / AO4854, Fairchild FDS8884, Vishay Si4214DDY, IR BSO150N03MD G, Potens PDS3812, and dintek DTM4926 / DTM4936.
