Description and Introduction

1200V 45A Doubler Circuit Positive Phase Control Thyristor/Diode in a ADD-A-Pak package The IRKH41/12 is a thyristor module manufactured by **IR (International Rectifier)**. Below are the factual specifications, descriptions, and features based on available knowledge:

### **Specifications:**  
- **Type:** Thyristor/SCR Module  
- **Voltage Rating (VDRM/VRRM):** 1200V  
- **Current Rating (IT(RMS)):** 41A  
- **Gate Trigger Current (IGT):** Typically 50mA  
- **Gate Trigger Voltage (VGT):** Typically 1.5V  
- **On-State Voltage Drop (VTM):** ~1.7V (typical at rated current)  
- **Critical Rate of Rise of Off-State Voltage (dv/dt):** 1000V/µs (min)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Mounting:** Module (chassis or heatsink mounting)  

### **Description:**  
The IRKH41/12 is a high-power thyristor module designed for industrial applications requiring reliable switching in AC power control, motor drives, and soft starters. It is part of IR's **KH series** of thyristor modules, known for robust construction and high surge current capability.

### **Features:**  
- **High Voltage & Current Handling:** Suitable for medium-power applications.  
- **Isolated Base:** Electrically isolated for simplified heatsink mounting.  
- **Low Thermal Resistance:** Efficient heat dissipation.  
- **High Surge Current Capability:** Withstands short-term overloads.  
- **Reliable Switching Performance:** Optimized for AC power control.  

These details are based on standard IRKH series specifications. For exact datasheet parameters, refer to the official IR documentation.
