Description and Introduction

NPN Silicon Switching Transistor with... The SMBT3904 is a general-purpose NPN bipolar junction transistor (BJT) manufactured by Infineon Technologies. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Transistor Type:** NPN  
- **Maximum Collector-Emitter Voltage (VCE):** 40V  
- **Maximum Collector-Base Voltage (VCB):** 60V  
- **Maximum Emitter-Base Voltage (VEB):** 6V  
- **Continuous Collector Current (IC):** 200mA  
- **Total Power Dissipation (Ptot):** 350mW  
- **DC Current Gain (hFE):** 100 to 300 (at IC = 10mA, VCE = 1V)  
- **Transition Frequency (fT):** 300MHz  
- **Operating Temperature Range:** -55°C to +150°C  

### **Description:**
The SMBT3904 is a small-signal transistor designed for switching and amplification applications. It is housed in a SOT-23 surface-mount package, making it suitable for compact PCB designs.  

### **Features:**
- High current gain (hFE)  
- Low saturation voltage  
- Fast switching speed  
- RoHS compliant  
- Suitable for general-purpose amplification and switching circuits  

This information is based on Infineon's datasheet for the SMBT3904.
