Product details

650 V, 20 A N-channel MOSFET in TO-220 — MDmesh M2

The STP28N65M2 is a 650 V, 20 A N-channel power MOSFET from STMicroelectronics' MDmesh™ M2 series, housed in a TO-220 through-hole package. It targets high-efficiency switching applications such as power factor correction (PFC), LLC resonant converters, and flyback topologies in AC-DC supplies for industrial and consumer equipment. The MDmesh M2 technology delivers a low on-resistance of 180 mOhm at 10 A, 10 V drive, combined with a gate charge of 35 nC, keeping switching losses manageable in hard-switched designs.

Ratings that matter for the BOM

The 650 V drain-source rating provides margin for DC-link rails in PFC stages.

ROHS3 compliant. The MDmesh M2 series remains a mainstream offering from ST, so the part is readily available through independent distribution channels for both prototype and production volumes.

Frequently asked questions

What is the equivalent of STP28N65M2?

Within the MDmesh M2 series, the STP28N65M2 is a 650 V, 20 A device in TO-220. The MDmesh M5 variant (STP28N65M5) offers a lower Rds(on) at a higher gate charge — trade conduction loss for switching speed. For a pin-compatible alternative in the same package, consider the STP28N65M5 if the switching frequency allows the higher Qg.

Is STP28N65M2 RoHS compliant?

Yes, the STP28N65M2 is ROHS3 compliant.
