Description and Introduction

Dual N-Channel 30-V (D-S) MOSFET The SI4922DY is a dual N-channel MOSFET manufactured by Siliconix (a subsidiary of Vishay). Here are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Drain-Source Voltage (VDSS):** 30V  
- **Gate-Source Voltage (VGSS):** ±20V  
- **Drain Current (ID):** 5.3A (per channel)  
- **Power Dissipation (PD):** 2W (per channel)  
- **On-Resistance (RDS(on)):** 0.035Ω (max at VGS = 10V)  
- **Gate Charge (Qg):** 13nC (typical)  
- **Threshold Voltage (VGS(th)):** 1V to 2.5V  
- **Package:** SOIC-8  

### **Description:**  
The SI4922DY is a dual N-channel MOSFET designed for high-efficiency power management applications. It is commonly used in DC-DC converters, motor control, and load switching circuits.  

### **Features:**  
- Low on-resistance for reduced conduction losses  
- Fast switching performance  
- Dual N-channel configuration in a compact SOIC-8 package  
- Suitable for high-frequency applications  
- Lead-free and RoHS compliant  

This information is based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

Dual N-Channel 30-V (D-S) MOSFET

Alternative Part Number

  • FDS6680A --: N-channel MOSFET in SO-8 with comparable RDS(on) and voltage rating, widely available and pin-compatible.
  • IRF7413 --: SO-8 N-channel MOSFET with similar current and voltage ratings, suitable drop-in replacement for switching applications.
  • AO4406 --: SO-8 N-channel MOSFET offering comparable on-resistance and current capability at lower cost.
  • NTMS4920N --: SO-8 N-channel MOSFET offering comparable on-resistance and current capability, good second-source option.
