ELM34411AA MOSFET — Specifications & Equivalents
About the ELM34411AA
The ELM34411AA is a P-channel MOSFET with a drain–source voltage (VDS) rating of 30 V, a continuous drain current (ID) of 12 A and an on-resistance (RDS(on)) of 0.014 Ω. It can dissipate up to 2.5 W and is rated to a junction temperature of 150 °C. It is supplied in the SOP-8 package.

Typical applications
With its 30 V drain–source rating the ELM34411AA sits in the low-voltage class of switching MOSFETs, typically found in 12 V and 24 V automotive and industrial rails, synchronous buck converters, load switching and reverse-polarity protection and H-bridges for small motors.
The low 0.014 Ω on-resistance keeps conduction loss down, which suits synchronous rectification and continuous high-current paths.
Gate drive and switching notes
Keep gate–source voltage within the ±25 V maximum; exceeding it punctures the gate oxide and destroys the device permanently.
Switching behaviour is characterised by a rise time of 16 ns and an output capacitance (Coss) of 870 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.
Choosing a replacement for the ELM34411AA
A drop-in substitute for the ELM34411AA must be the same P-channel type and offer a drain–source rating of at least 30 V, a continuous drain current rating of at least 12 A and an on-resistance no higher than 0.014 Ω if efficiency and heat matter.
Mechanically, check the replacement against the SOP-8 footprint and confirm the pin order — parts sharing a package outline do not always share a pinout.
Where the application switches inductive loads or runs near the voltage limit, keep extra headroom rather than choosing a part that only just meets the original numbers.
Frequently asked questions
What is the ELM34411AA?
The ELM34411AA is a P-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 30 V drain-source and 12 A continuous drain current.
What is the maximum voltage of the ELM34411AA?
The ELM34411AA has a maximum drain-source voltage (Vds) of 30 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.
How much current can the ELM34411AA handle?
It is rated for 12 A of continuous drain current, with power dissipation limited to 2.5 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the ELM34411AA?
On-resistance (Rds(on)) is 0.014 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the ELM34411AA come in?
It is listed in SOP-8. Verify the pinout of the specific variant, as one outline can carry different pin assignments.
What can I use to replace the ELM34411AA?
No verified equivalents are listed yet. Choose a part of the same polarity that meets or exceeds every rating above and shares a compatible package and pinout.
