4611 MOSFET — Specifications & Equivalents

About the 4611

The 4611 is a complementary N- and P-channel MOSFET with a drain–source voltage (V_DS) rating of 60 V, a continuous drain current (I_D) of 6.3 A and an on-resistance (R_DS(on)) of 0.025 Ω. It can dissipate up to 2 W and is rated to a junction temperature of 150 °C. It is supplied in the SOP8 package.

Typical applications

With its 60 V drain–source rating the 4611 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.

The low 0.025 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 ±20 V maximum; exceeding it punctures the gate oxide and destroys the device permanently.

Choosing a replacement for the 4611

A drop-in substitute for the 4611 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 6.3 A and an on-resistance no higher than 0.025 Ω if efficiency and heat matter.

Mechanically, check the replacement against the SOP8 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 4611?

The 4611 is a complementary N- and P-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 60 V drain-source and 6.3 A continuous drain current.

What is the maximum voltage of the 4611?

The 4611 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 4611 handle?

It is rated for 6.3 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 4611?

On-resistance (Rds(on)) is 0.025 Ω. Multiply by the square of your load current to estimate conduction loss.

What package does the 4611 come in?

It is listed in SOP8. Verify the pinout of the specific variant, as one outline can carry different pin assignments.

What can I use to replace the 4611?

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.
