AI summary

DO3401BA product

DO3401BA is a -30 V P-channel MOSFET in SOT-23-3 with a maximum 52 mΩ RDS(on) at -10 V gate drive and a -4.3 A continuous-current rating at 25°C.

Best for

Low-voltage P-channel MOSFET designs within the -30 V rating
Space-constrained SOT-23-3 circuits

Avoid if

Gate-source voltage can exceed ±12 V
The design requires verified compliance, lifecycle, or qualification data not provided in the datasheet

Check before use

Confirm pin 1 gate, pin 2 drain, pin 3 source
Use the applicable RDS(on) limit for the selected VGS
Validate junction temperature using the actual PCB thermal environment
