Description and Introduction

1200V 140A Doubler Circuit Positive Phase Control Thyristor/Thyristor in a INT-A-Pak package The IRKT142-12 is a thyristor module manufactured by **Infineon Technologies**. Below are the key specifications, descriptions, and features based on the available knowledge base:

### **Specifications:**
- **Type:** Thyristor/Diode Module  
- **Voltage Rating (VDRM/VRRM):** 1200 V  
- **Current Rating (IT(RMS)/ITAV):** 142 A  
- **Maximum Surge Current (ITSM):** 2200 A (for 10 ms)  
- **Gate Trigger Current (IGT):** 150 mA (max)  
- **Gate Trigger Voltage (VGT):** 1.5 V (max)  
- **On-State Voltage Drop (VTM):** 1.55 V (typical at rated current)  
- **Critical Rate of Rise of Off-State Voltage (dv/dt):** 1000 V/µs  
- **Operating Junction Temperature (Tj):** -40°C to +125°C  

### **Description:**
- The **IRKT142-12** is a high-power thyristor module designed for industrial applications requiring robust switching capabilities.  
- It features a **press-fit** or **screw-type** terminal design for secure connections.  
- The module is commonly used in **AC motor controls, power supplies, and industrial inverters**.  

### **Features:**
- **High Surge Current Capability** – Supports short-term overload conditions.  
- **Low Thermal Resistance** – Efficient heat dissipation due to an insulated base plate.  
- **Isolated Mounting Base** – Allows direct mounting to a heatsink without insulation.  
- **High dv/dt and di/dt Ratings** – Ensures reliable switching performance.  
- **UL Recognized** – Compliant with safety standards for industrial use.
