Description and Introduction

1200V 95A Doubler Circuit Positive Phase Control Thyristor/Thyristor in a ADD-A-Pak package The IRKT91/12 is a thyristor module manufactured by **Infineon Technologies**. Below are the key specifications, descriptions, and features based on available data:

### **Specifications:**
- **Type:** Thyristor Module (Phase Control)  
- **Voltage Rating (VDRM/VRRM):** 1200 V  
- **Current Rating (IT(RMS)):** 91 A  
- **On-State Current (ITAV):** 58 A  
- **Gate Trigger Current (IGT):** 50 mA (typical)  
- **Gate Trigger Voltage (VGT):** 1.5 V (typical)  
- **Holding Current (IH):** 200 mA (typical)  
- **Critical Rate of Rise of Voltage (dv/dt):** 1000 V/µs (min)  
- **Operating Temperature Range:** -40°C to +125°C  

### **Description:**
- The IRKT91/12 is a high-power thyristor module designed for industrial applications requiring phase control, such as motor drives, power supplies, and heating controls.  
- It features a **press-fit** or **screw-type** terminal configuration for robust electrical connections.  
- The module is designed for **high surge current capability** and **reliable switching performance**.  

### **Features:**
- **High Voltage & Current Handling:** Suitable for demanding power control applications.  
- **Low Thermal Resistance:** Efficient heat dissipation due to an insulated baseplate.  
- **Isolated Mounting:** Allows direct mounting to a heatsink without insulation.  
- **High dv/dt Capability:** Ensures stable switching under fast voltage transients.  
- **Compliant with Industry Standards:** Meets relevant safety and performance certifications.  

For exact mechanical dimensions and application notes, refer to the official **Infineon datasheet**.
