ELM34608AA MOSFET — Specifications & Equivalents
About the ELM34608AA
The ELM34608AA is a complementary N- and P-channel MOSFET with a drain–source voltage (VDS) rating of 60 V, a continuous drain current (ID) of 4.5 A and an on-resistance (RDS(on)) of 0.058 Ω. It can dissipate up to 2 W and is rated to a junction temperature of 150 °C. It is supplied in the SOP-8 package.

Typical applications
With its 60 V drain–source rating the ELM34608AA sits in the mid-range class of switching MOSFETs, typically found in 24 V and 48 V industrial and battery systems, motor drives and H-bridges and load and hot-swap switching.
Gate drive and switching notes
Keep gate–source voltage within the ±20 V maximum; exceeding it punctures the gate oxide and destroys the device permanently.
Switching behaviour is characterised by a rise time of 8 ns and an output capacitance (Coss) of 80 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.
Choosing a replacement for the ELM34608AA
A drop-in substitute for the ELM34608AA must be the same complementary N- and P-channel type and offer a drain–source rating of at least 60 V, a continuous drain current rating of at least 4.5 A and an on-resistance no higher than 0.058 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 ELM34608AA?
The ELM34608AA is a complementary N- and P-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 60 V drain-source and 4.5 A continuous drain current.
What is the maximum voltage of the ELM34608AA?
The ELM34608AA has a maximum drain-source voltage (Vds) of 60 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.
How much current can the ELM34608AA handle?
It is rated for 4.5 A of continuous drain current, with power dissipation limited to 2 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the ELM34608AA?
On-resistance (Rds(on)) is 0.058 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the ELM34608AA 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 ELM34608AA?
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.
