Product details

650 V switch in a 3.3x3.3 mm footprint

The STL3N65M2: It comes in the PowerFlat™ 3.3x3.3 package — a low-profile, surface-mount package suited for space-constrained offline supplies and auxiliary converters where board height is a constraint.

On-resistance and drive requirements

Input capacitance Ciss is 155 pF at 100 V drain bias — a light load for the gate driver.

Thermal and operating envelope

Maximum power dissipation is 22 W at case temperature — achievable with adequate PCB copper on the PowerFlat drain pad. The 4 V maximum gate threshold at 250 µA ensures the device is fully off below 4 V, typical for logic-level drive.

Frequently asked questions

What is the typical application for STL3N65M2?

This 650 V MDmesh M2 MOSFET is suited for offline flyback converters, auxiliary power supplies, PFC stages, and LED drivers where the drain current stays below 2.3 A and the package height must be under 1 mm.
