P-channel SOT-23 MOSFET with higher current but lower voltage rating.
BSS84LT1G is a P-channel SOT-23 MOSFET. The listed alternates need FAE review, mainly for Vdss and pinout.
Vdss is lower than -50 V.
Kept parts are SOT-23-3.
Discrete MOSFET.
Lifecycle varies by part.
No verified pin-compatible replacement is proven from these candidates.
Start with SI2319CDS-T1-GE3 only if -40 V is enough.
Lower drain-source voltage on kept candidates.
