STP11NK40Z Description

The STP11NK40Z from STMicroelectronics is an N-channel Power MOSFET designed for high-voltage switching applications. Built on SuperMESH™ technology, it offers a robust 400V drain-to-source voltage (Vdss) rating and a continuous drain current (Id) of 9A at 25°C (case temperature). With a low on-resistance (Rds(on)) of 550mΩ at 10V gate drive, it ensures efficient power handling while minimizing conduction losses. The device is housed in a TO-220AB package, making it suitable for through-hole mounting in demanding industrial and consumer electronics applications.

STP11NK40Z Features

• High Voltage Rating: 400V Vdss for reliable operation in high-voltage circuits.
• Low Gate Charge (Qg): 32nC at 10V ensures fast switching and reduced drive losses.
• Low Input Capacitance (Ciss): 930pF at 25V enhances high-frequency performance.
• SuperMESH™ Technology: Delivers superior Rds(on) vs. gate charge trade-off, improving efficiency.
• Wide Gate-Source Voltage Range: ±30V Vgs(max) for flexible drive compatibility.
• Thermal Performance: 110W max power dissipation (Tc) ensures reliability under high loads.
• Compliance: ROHS3 and REACH compliant, with MSL 1 (unlimited) moisture sensitivity for easy handling.

STP11NK40Z Applications

• Switched-Mode Power Supplies (SMPS): Ideal for AC-DC converters, PFC stages, and offline power supplies due to its high voltage and low Rds(on).
• Motor Control: Suitable for inverters and H-bridge circuits in industrial motor drives.
• Lighting Systems: Efficiently drives LED drivers and electronic ballasts.
• Consumer Electronics: Used in TV power supplies, adapters, and battery chargers.
• Industrial Automation: Reliable performance in relay replacements and solenoid drivers.
