Description and Introduction

NPN Epitaxial Silicon Transistor The KSD401 is a thermal protector manufactured by FAIRCHILD. Below are the factual specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** Thermal protector (bimetal disc thermostat)  
- **Rated Voltage:** 250V AC  
- **Rated Current:** 10A  
- **Temperature Range:** Typically operates within a range of -20°C to +150°C (exact trip/reset temperatures may vary by model)  
- **Contact Type:** Normally Closed (NC) or Normally Open (NO) depending on variant  
- **Termination:** Quick connect or solder terminals  
- **Housing Material:** Flame-retardant plastic  

### **Descriptions:**  
- The KSD401 is a snap-action thermal switch designed to automatically open or close an electrical circuit in response to temperature changes.  
- It is commonly used in appliances such as electric kettles, rice cookers, and other heating devices for over-temperature protection.  
- The device resets automatically when the temperature drops below the set threshold (for auto-reset models).  

### **Features:**  
- **Bimetal Disc Technology:** Ensures reliable switching based on temperature changes.  
- **High Current Rating:** Capable of handling up to 10A at 250V AC.  
- **Compact Design:** Small form factor for easy integration into various applications.  
- **Fast Response:** Quick reaction to temperature fluctuations for safety.  
- **Durable Construction:** Flame-retardant housing enhances safety in high-temperature environments.  

For exact trip/reset temperatures and other model-specific details, refer to the official FAIRCHILD datasheet.
