Product details

Package and mounting — DPAK for automated assembly

The DPAK (TO-252) footprint is a standard surface-mount package for medium-power MOSFETs, compatible with reflow soldering and pick-and-place lines. The tab is the drain terminal; PCB layout should allocate sufficient copper area for thermal dissipation — the device is rated for 90 W power dissipation at case temperature, so a thermal via pattern under the tab is recommended for continuous operation above 3 A. The supplier device package is listed as DPAK, and the base product number is STD6N95.

Lifecycle and sourcing

The STD6N95K5 carries an active product status — no last-time-buy or end-of-life notice is in effect. It can be specified into new designs with confidence.

Frequently asked questions

Is STD6N95K5 RoHS compliant?

Yes, the STD6N95K5 is ROHS3 compliant, meeting the latest EU restriction of hazardous substances directive for lead-free soldering.

What is the closest pin-compatible alternative to STD6N95K5 in this component family?

Within the same SuperMESH5™ family, the STD6N95K4 is a close variant. The key difference is the drain-to-source voltage rating — the K5 is rated at 950 V, while the K4 is typically rated at 900 V. Both share the same DPAK footprint and pinout, so the K4 can serve as a drop-in replacement where the voltage margin is acceptable, but verify the exact Vdss against your rail voltage before substituting.

Is STD6N95K5 equivalent to IRF840?

No, the IRF840 is a 500 V, 8 A MOSFET in a TO-220 through-hole package, while the STD6N95K5 is a 950 V, 9 A surface-mount DPAK device. They are not pin-compatible or electrically equivalent; the STD6N95K5 targets higher-voltage applications and a different assembly process.
