Description and Introduction

Si-Epitaxial PlanarTransistors The BC546 is a general-purpose NPN bipolar junction transistor (BJT) commonly used in amplification and switching applications. Below are its key specifications:

1. **Manufacturer**: Multiple manufacturers produce the BC546, including ON Semiconductor, Fairchild Semiconductor, and STMicroelectronics.  

2. **Polarity**: NPN  
3. **Package**: TO-92  
4. **Collector-Emitter Voltage (VCEO)**: 65V  
5. **Collector-Base Voltage (VCBO)**: 80V  
6. **Emitter-Base Voltage (VEBO)**: 6V  
7. **Continuous Collector Current (IC)**: 100mA  
8. **Total Power Dissipation (Ptot)**: 500mW  
9. **DC Current Gain (hFE)**: Typically 110–800 (varies by suffix: A, B, or C)  
10. **Transition Frequency (fT)**: ~300MHz  
11. **Operating Temperature Range**: -55°C to +150°C  

The BC546 is available in different gain groupings:  
- **BC546A**: hFE = 110–220  
- **BC546B**: hFE = 200–450  
- **BC546C**: hFE = 420–800  

These specifications may vary slightly depending on the manufacturer. Always refer to the datasheet for precise details.
