The WST3406 MOSFET is an N-channel device featuring a drain-source voltage (VDS) of 30V, a gate-source voltage (VGS) of ±20V, a continuous drain current (ID) of 6.8A, and a maximum RDS(ON) resistance of 20mΩ at 10V. It is packaged in a SOT-23-3L format.
While both support 30V VDS and use the SOT-23-3L package, the WST3406A has a lower VGS rating of ±12V, a slightly higher current capacity of 7A, lower RDS(ON) at lower gate drive voltages (18mΩ Typ. at 4.5V), and a higher input capacitance (Ciss) of 572pF compared to 416pF for WST3406.
These MOSFETs are widely applied in digital products, small home appliances, and various consumer electronics systems requiring efficient power switching and management.
Both the WST3406 and WST3406A MOSFETs utilize the compact SOT-23-3L surface-mount package, which is ideal for space-constrained electronics designs.
Cross-reference equivalent models include AOS MOSFETs (AO3400, AO3400A, AO3404), Onsemi/Fairchild FDN537N, STMicroelectronics STT6N3LLH6, NIKO-SEM P3203CMG, Potens PDN3912S, and DINTEK DTS3406.
