Description and Introduction

Tech Electronics LTD - Dual General Purpose Transistors The MBT3904DW is a dual NPN bipolar junction transistor (BJT) manufactured by Taiwan Semiconductor (TAIWAN). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Type:** Dual NPN BJT  
- **Package:** SOT-363 (SC-88)  
- **Collector-Base Voltage (VCB):** 40V  
- **Collector-Emitter Voltage (VCE):** 40V  
- **Emitter-Base Voltage (VEB):** 5V  
- **Collector Current (IC):** 200mA (per transistor)  
- **Total Power Dissipation (Ptot):** 200mW  
- **DC Current Gain (hFE):** 100-300 (at IC = 10mA, VCE = 1V)  
- **Transition Frequency (fT):** 250MHz (typical)  
- **Operating Temperature Range:** -55°C to +150°C  

### **Descriptions:**  
- The MBT3904DW consists of two independent NPN transistors in a single SOT-363 package.  
- Designed for general-purpose amplification and switching applications.  
- Suitable for high-speed switching due to its high transition frequency.  

### **Features:**  
- **Dual NPN configuration** in a compact package.  
- **High current gain (hFE)** for efficient amplification.  
- **Low saturation voltage** for improved switching performance.  
- **High transition frequency (fT)** for fast switching applications.  
- **Small form factor (SOT-363)** suitable for space-constrained designs.  

This information is based on the manufacturer's datasheet for the MBT3904DW.

Application Scenarios & Design Considerations

Alternative Part Number

  • MMDT3904 --: Dual NPN 3904 transistor in SOT-363, same pinout and electrical characteristics as the original dual 3904 device.
  • PMP3904 --: Matched dual NPN 3904 pair in SOT-363 package, directly interchangeable for switching and amplifier applications.
  • UMT3904 --: Dual NPN 3904 transistor in SOT-363, comparable Vceo and current ratings, suitable drop-in replacement.
  • BC847BS --: Dual NPN transistor in SOT-363 with comparable 45V/100mA ratings, a common European equivalent often used where MBT3904DW is specified.
  • PMBT3904 --: Single NPN 40V/200mA transistor in SOT-23; use two devices if the dual package is not essential, offering a well-established and low-cost alternative.
