Description and Introduction

N-CHANNEL 500V The STD4NK50Z is a N-channel 500V, 4A Zener-protected SuperMESH™ Power MOSFET manufactured by STMicroelectronics.  

### **Specifications:**  
- **Drain-Source Voltage (VDSS):** 500V  
- **Continuous Drain Current (ID):** 4A  
- **Pulsed Drain Current (IDM):** 16A  
- **Power Dissipation (Ptot):** 50W  
- **Gate-Source Voltage (VGS):** ±30V  
- **On-Resistance (RDS(on)):** 1.5Ω (max) at VGS = 10V  
- **Input Capacitance (Ciss):** 450pF (typ)  
- **Output Capacitance (Coss):** 45pF (typ)  
- **Reverse Transfer Capacitance (Crss):** 8pF (typ)  
- **Turn-On Delay Time (td(on)):** 10ns (typ)  
- **Turn-Off Delay Time (td(off)):** 55ns (typ)  
- **Zener Diode Clamping Voltage:** 15V (typ)  

### **Description:**  
The STD4NK50Z is designed for high-voltage, high-speed switching applications. It features ST's SuperMESH™ technology, which reduces on-resistance and improves switching performance. The built-in Zener diode protects the gate against overvoltage.  

### **Features:**  
- **Zener-protected gate** for enhanced reliability  
- **Low gate charge** for fast switching  
- **Low on-resistance** for reduced conduction losses  
- **100% avalanche tested** for ruggedness  
- **Optimized for high-efficiency applications**  

### **Package:**  
- **TO-252 (DPAK)** surface-mount package  

This MOSFET is suitable for power supplies, lighting, motor control, and other high-voltage switching applications.
