What is the difference between WST3415A and WST3415?
The WST3415 includes integrated ESD protection (Single+ESD) and offers slightly higher current handling (-5.5A) with lower RDS(ON) resistance (44mΩ typical @ 4.5V) compared to the WST3415A (-5.3A and 58mΩ typical @ 4.5V). Both are packaged in the SOT-23-3L format.
What are the standard applications for these MOSFETs?
These P-channel MOSFETs are highly suited for power management and switching in applications like e-cigarettes, system controllers, digital products, small household appliances, and other consumer electronics.
What package type is used for WST3415A and WST3415?
Both models are packaged in a standard SOT-23-3L format, which provides a compact footprint ideal for high-density circuit board layouts.
Which equivalent MOSFET models can be cross-referenced with this series?
These devices can replace or serve as alternatives to AOS MOSFETs (AO3413, AO3415A, AO3419, AO3423, AO3435, AO3493, AO3495, AO3499, AO21115C), PANJIT MOSFET (PJA3457), and Potens MOSFET (PDEN2423S).
What is the operating voltage (VDS) limit of these devices?
Both the WST3415A and WST3415 MOSFETs have a maximum drain-source voltage (VDS) limit of -20V, making them suitable for low-voltage power path switching.
