600 V, 34 A N-channel MOSFET in a full-pack through-hole package

Key switching characteristics for SMPS and PFC designs

With a maximum gate charge of 55 nC at 10 V and input capacitance of 2370 pF at 100 V drain-source, the STFW42N60M2-EP is sized for hard-switched topologies like single-switch forward converters, two-switch flyback, and power-factor-correction boost stages. The low gate charge keeps driver losses manageable at switching frequencies in the 50–100 kHz range.

Obsolete status and sourcing

The STFW42N60M2-EP is listed as obsolete. For production builds, a pin-compatible replacement from the same MDmesh M2 family should be qualified.

Frequently asked questions

What is the replacement for STFW42N60M2-EP?

Buyers need a drop-in or functionally equivalent part to keep their design or repair functional now that the original is obsolete.

Is STFW42N60M2-EP obsolete?

Knowing the lifecycle status drives sourcing decisions, inventory planning, and whether to seek alternatives.

Where can I buy STFW42N60M2-EP?

Even though obsolete, some distributors may have remaining stock; buyers need to quickly locate available units.

What is the datasheet for STFW42N60M2-EP?

Engineers require the datasheet to validate electrical characteristics, pinout, and thermal data for design or replacement.

What are the key specifications of STFW42N60M2-EP?

Quick access to Vgs, Rds(on), Id, and package details helps engineers assess fit without reading the full datasheet.

What is the equivalent to STFW42N60M2-EP?

Sourcing buyers and brokers search for cross-references to find alternative MOSFETs from other manufacturers that match the original specs.
