- **Collector-Base Voltage (VCBO):** -40V  
- **Collector-Emitter Voltage (VCEO):** -30V  
- **Emitter-Base Voltage (VEBO):** -5V  
- **Collector Current (IC):** -600mA  
- **Power Dissipation (PD):** 625mW  
- **DC Current Gain (hFE):** 120-250 (at IC = -150mA, VCE = -1V)  
- **Transition Frequency (fT):** 250MHz (typical)  
- **Operating Temperature Range:** -55°C to +150°C  

### **Description:**  
The KSR2202 is a general-purpose PNP transistor designed for amplification and switching applications. It is housed in a **TO-92** package, making it suitable for compact circuit designs.  

### **Features:**  
- High current gain (hFE)  
- Low saturation voltage  
- Fast switching speed  
- Reliable performance in amplification circuits  

This transistor is commonly used in audio amplifiers, signal processing, and low-power switching applications.  

(Note: Always refer to the official datasheet for precise details before implementation.)
