Description and Introduction

P-N-P-N SILICON REVERSE-BLOCKING TRIODE THYRISTORS The TIC126D 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):** 200V to 600V (depending on variant)  
- **Average On-State Current (IT(AV)):** 8A  
- **Non-Repetitive Peak On-State Current (ITSM):** 80A (for 8.3ms half-sine wave)  
- **Gate Trigger Current (IGT):** 5mA (max)  
- **Gate Trigger Voltage (VGT):** 0.8V (max)  
- **Holding Current (IH):** 5mA (max)  
- **Operating Temperature Range:** -40°C to +110°C  
- **Package:** TO-220AB (isolated tab)  

### **Description:**  
The TIC126D is a high-current SCR designed for power control applications, including motor controls, industrial switching, and AC power regulation. It features a sensitive gate for low-power triggering and is available in multiple voltage ratings.  

### **Features:**  
- High surge current capability  
- Electrically isolated mounting base (TO-220AB)  
- Low gate trigger requirements  
- Suitable for high-reliability industrial applications  

For exact voltage ratings and additional details, refer to the specific datasheet for the TIC126D variant.

Application Scenarios & Design Considerations

Alternative Part Number

  • 2N6397 --: TO-220 SCR with similar 12A current rating and 400V blocking voltage, widely available and a common cross for TIC126 series devices.
  • C106D --: Sensitive-gate SCR in TO-220 with 400V rating and comparable gate characteristics, suitable for many TIC126D applications.
  • BT151-500R --: Popular TO-220 SCR rated 12A and 500V, offering higher voltage margin and similar gate trigger behavior as a practical substitute.
  • MCR12DSN --: 12A/400V SCR in TO-220 package with similar gate characteristics, suitable as a functional replacement where the TIC126D is used.
