Description and Introduction

N-CHANNEL 400V 0.49 OHM 9A TO-220/TO-220FP/D2PAK ZENER-PROTECTED SUPERMESH POWER MOSFET The STB11NK40ZT4 is an N-channel Power MOSFET manufactured by STMicroelectronics.  

### **Specifications:**  
- **Voltage Rating (VDSS):** 400V  
- **Current Rating (ID):** 11A (at 25°C)  
- **RDS(on) (Max):** 0.45Ω (at VGS = 10V)  
- **Gate-Source Voltage (VGS):** ±30V  
- **Power Dissipation (PD):** 45W  
- **Package:** TO-263 (D2PAK)  

### **Descriptions:**  
- Designed for high-efficiency switching applications.  
- Low gate charge and low on-resistance for reduced conduction losses.  
- Suitable for power supplies, motor control, and lighting applications.  

### **Features:**  
- **Fast Switching:** Optimized for high-speed performance.  
- **Avalanche Rugged:** High energy capability.  
- **Low Threshold Voltage (VGS(th)):** Ensures compatibility with low-voltage drive circuits.  
- **100% Avalanche Tested:** Ensures reliability in harsh conditions.  

This MOSFET is commonly used in industrial and consumer electronics requiring high-voltage switching.

Application Scenarios & Design Considerations

N-CHANNEL 400V 0.49 OHM 9A TO-220/TO-220FP/D2PAK ZENER-PROTECTED SUPERMESH POWER MOSFET

Alternative Part Number

  • IRF740PBF --: 400V N-channel MOSFET in TO-220 with comparable RDS(on) and current rating, widely available and a common substitute for 400V switching applications.
  • FQP9N40 --: 400V N-channel MOSFET rated around 9A, similar voltage and current class, suitable drop-in for many 400V switching designs.
  • 2SK3569 --: 400V N-channel power MOSFET with comparable ratings, usable as an alternative where gate charge and package constraints allow.
