Description and Introduction

P-N-P-N SILICON REVERSE-BLOCKING TRIODE THYRISTORS The TIC126N is a silicon-controlled rectifier (SCR) manufactured by Texas Instruments (TI). Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Type:** Silicon-Controlled Rectifier (SCR)  
- **Repetitive Peak Off-State Voltage (VDRM):** 400V  
- **Repetitive Peak Reverse Voltage (VRRM):** 400V  
- **RMS On-State Current (IT(RMS)):** 12A  
- **Average On-State Current (IT(AV)):** 8A  
- **Non-Repetitive Surge Current (ITSM):** 120A (for 8.3ms half-sine wave)  
- **Gate Trigger Current (IGT):** 5mA (max)  
- **Gate Trigger Voltage (VGT):** 1.5V (max)  
- **Holding Current (IH):** 5mA (max)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-220 (isolated tab)  

### **Descriptions:**  
- The TIC126N is a high-current SCR designed for power control applications.  
- It is suitable for AC switching, motor control, and industrial power systems.  
- The device features a sensitive gate for low-triggering requirements.  

### **Features:**  
- **High Surge Current Capability:** Supports high inrush current conditions.  
- **Isolated Tab:** Allows for easier heat sinking and electrical isolation.  
- **Sensitive Gate:** Low gate trigger current and voltage requirements.  
- **Reliable Switching:** Robust construction for industrial applications.  

This information is strictly based on the manufacturer's datasheet for the TIC126N SCR.

Alternative Part Number

  • 2N6397 --: SCR with similar 12A current rating and 400V voltage class, widely available and commonly used as a substitute in power control circuits.
  • C106M --: Sensitive-gate SCR rated 4A/600V, suitable for lower-current applications where the TIC126N is used for switching and phase control.
  • BT151-500R --: 12A SCR in TO-220 package with 500V rating, offering comparable gate characteristics and a different series naming for easy distinction.
  • 2N6403G --: SCR rated 800V/16A in TO-220, similar current and voltage class to the TIC126N, widely available and pin-compatible.
  • S4016R --: 16A SCR in TO-220 package with comparable gate sensitivity and blocking voltage, suitable drop-in replacement for switching applications.
  • BT151-800R --: 800V/12A SCR in TO-220, close electrical match with similar gate trigger characteristics and package footprint.
