The WST3401A and WST3401 are high-performance P-channel MOSFETs designed with a -30V voltage rating, -5A current capacity, and a typical resistance of 48mΩ. Both devices are housed in the industry-standard SOT-23-3L package.
Ideally suited for small home appliance MOSFET applications, digital product power management, and LED light MOSFET driver circuits.
Compatible equivalents and replacements include AOS MOSFET models (AO3401, AO3401A, AO3453, AO3459, AO3407, AO3407A), PANJIT MOSFET (PJA55P03), and Potens MOSFET (PDN2309S).

The WST3401A MOSFET operates at a voltage (VDS) of -30V and supports a continuous drain current (ID) of -5A.
Both the WST3401 and WST3401A P-channel MOSFETs are packaged in the compact SOT-23-3L surface-mount package.
They are commonly used in digital products, small home appliances, and driver circuits for LED lighting systems.
These parts can effectively cross-reference with AOS models (AO3401, AO3401A, AO3453, AO3459, AO3407, AO3407A), PANJIT model (PJA55P03), and Potens model (PDN2309S).
At a 10V gate-source voltage drive, the WST3401A has an RDS(ON) of 48mΩ, whereas the WST3401 has a slightly lower typical RDS(ON) of 44mΩ.
