EM6M2 MOSFET — Specifications & Equivalents
About the EM6M2
The EM6M2 is a complementary N- and P-channel MOSFET with a drain–source voltage (VDS) rating of 20 V, a continuous drain current (ID) of 0.2 A and an on-resistance (RDS(on)) of 1 Ω. It can dissipate up to 0.15 W and is rated to a junction temperature of 150 °C. It is supplied in the SOT-563 package.

Typical applications
With its 20 V drain–source rating the EM6M2 sits in the very-low-voltage class of switching MOSFETs, typically found in battery protection and power-path switching, point-of-load converters and logic-level load switching in portable devices.
At 0.2 A it is aimed at small-signal and light-load switching rather than power conversion.
On-resistance of 1 Ω is relatively high, so this part is better suited to low duty-cycle or low-current switching than to continuous high-current conduction.
Gate drive and switching notes
Keep gate–source voltage within the ±8 V maximum; exceeding it punctures the gate oxide and destroys the device permanently.
Switching behaviour is characterised by a rise time of 10 ns and an output capacitance (Coss) of 10 pF, which together with the gate drive determines switching loss and the practical upper frequency limit.
Choosing a replacement for the EM6M2
A drop-in substitute for the EM6M2 must be the same complementary N- and P-channel type and offer a drain–source rating of at least 20 V, a continuous drain current rating of at least 0.2 A and an on-resistance no higher than 1 Ω if efficiency and heat matter.
Mechanically, check the replacement against the SOT-563 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 EM6M2?
The EM6M2 is a complementary N- and P-channel MOSFET (metal-oxide-semiconductor field-effect transistor). It is rated for 20 V drain-source and 0.2 A continuous drain current.
What is the maximum voltage of the EM6M2?
The EM6M2 has a maximum drain-source voltage (Vds) of 20 V. Treat this as an absolute maximum and design with margin, especially when switching inductive loads.
How much current can the EM6M2 handle?
It is rated for 0.2 A of continuous drain current, with power dissipation limited to 0.15 W. Real-world capability depends on your heatsinking and ambient temperature.
What is the on-resistance of the EM6M2?
On-resistance (Rds(on)) is 1 Ω. Multiply by the square of your load current to estimate conduction loss.
What package does the EM6M2 come in?
It is listed in SOT-563. Verify the pinout of the specific variant, as one outline can carry different pin assignments.
What can I use to replace the EM6M2?
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.
