STP3NK90Z Description

Short technical summary and product information.

The STP3NK90Z is a high-voltage N-Channel Power MOSFET manufactured by STMicroelectronics. It is designed for switching applications and features a 900V drain-source voltage (Vds) and a continuous drain current (Id) of 3A at a case temperature.

Key electrical characteristics include a maximum on-resistance (Rds(on)) of 4.8 Ohm at 1.5A and 10V gate-source voltage. The device also has a gate charge (Qg) of 22.7 nC and an input capacitance (Ciss) of 590 pF. The gate source threshold voltage (Vgs(th)) is a maximum of 4.5V at 50µA, and the maximum gate-to-source voltage is ±30V.

This MOSFET operates within a temperature range of -55°C to 150°C (TJ). It is housed in a TO-220FP package and is suitable for through-hole mounting. The power dissipation is rated at 90W (Tc) for the TO-220 package and 25W for the TO-220FP package.

The SuperMESH™ series, to which this MOSFET belongs, is optimized for low on-resistance and high dv/dt capability, making it suitable for demanding applications.
