Description and Introduction

NPN Medium Power Transistor (Switching) **Part Number:** UMT2222A  
**Manufacturer:** ROHM  

### **Specifications:**  
- **Type:** NPN Bipolar Junction Transistor (BJT)  
- **Package:** SOT-323 (Miniature Surface Mount)  
- **Collector-Emitter Voltage (VCEO):** 30V  
- **Collector Current (IC):** 600mA  
- **Power Dissipation (PD):** 150mW  
- **DC Current Gain (hFE):** 100 to 400 (at IC = 10mA, VCE = 5V)  
- **Transition Frequency (fT):** 250MHz (Typical)  
- **Operating Temperature Range:** -55°C to +150°C  

### **Descriptions:**  
The UMT2222A is a high-speed switching NPN transistor designed for general-purpose amplification and switching applications. It is optimized for low-voltage, high-current operation in compact circuits.  

### **Features:**  
- High current gain (hFE) for improved efficiency  
- Low saturation voltage for reduced power loss  
- Compact SOT-323 package for space-constrained designs  
- Suitable for high-speed switching (e.g., driver circuits, signal amplification)  
- Lead-free and RoHS compliant  

This information is based solely on ROHM's specifications for the UMT2222A transistor.
