Product details

The STD95N04 is marked Obsolete by STMicroelectronics. Any requirement for this exact part must be filled through the surplus or broker channel.

Maximum on-resistance of 6.5 mΩ at 40 A, 10 V gate drive. That Rds(on) figure governs conduction loss in the power stage; at 40 A the dissipation is roughly 10 W before accounting for temperature derating. The 110 W package limit at the case gives thermal headroom, but the junction-to-ambient path in a DPAK footprint is the practical constraint — board copper area and airflow matter. Gate charge of 54 nC at 10 V defines the drive requirement. A gate driver capable of sourcing and sinking that charge in the target switching cycle is needed to keep switching losses in check.

Surface-mount DPAK (TO-252-3) with the standard 2-lead-plus-tab footprint.

Frequently asked questions

Is STD95N04 obsolete?

Yes. STMicroelectronics lists the STD95N04 as Obsolete. It is no longer manufactured and must be sourced through surplus or independent distribution channels.

What is the replacement for STD95N04?

ST has not published an official successor for the STD95N04. A functionally similar N-channel MOSFET in DPAK with a 40 V drain-source rating and comparable Rds(on) would need evaluation — gate charge, threshold voltage, and switching characteristics must be checked against the original design's timing and drive budget.

Does STD95N04 come in a TO-252 package?

Yes. The STD95N04 is supplied in a DPAK (TO-252-3) surface-mount package, with the supplier device package also listed as DPAK.
