Product details

900 V N-channel MOSFET for high-voltage switching

The STP6NK90Z is a 900 V N-channel MOSFET in a TO-220-3 through-hole package.

The input capacitance of 1350 pF at 25 V drain-source is typical for a 900 V device of this current class; the gate-drive circuit should be sized to deliver the peak current needed for the target switching frequency without excessive crossover loss.

Temperature range and thermal design

The maximum power dissipation is 140 W at case temperature Tc.

For BOM lines that require a second-source option, ST's own SuperMESH family includes several 900 V N-channel devices in TO-220 with similar Rds(on) and current ratings — the base product number STP6NK90 covers the series, and the Z suffix denotes the specific SuperMESH generation.

Frequently asked questions

Where can I buy STP6NK90Z?

Buyers need immediate sourcing information to complete a BOM line or order replacement parts.

What is the price of STP6NK90Z?

Pricing drives procurement decisions and budget planning.

Is STP6NK90Z obsolete or active?

Lifecycle status determines long-term availability and risk for designs.

What are the exact specifications of STP6NK90Z?

Engineers need to validate fit with their circuit requirements (voltage, current, Rds on).

What is the replacement or equivalent for STP6NK90Z?

If stock is low or part is unavailable, buyers need alternatives to avoid redesign.

Does STP6NK90Z come in a different package?

Package compatibility affects board layout and through-hole vs SMT assembly.
