Description and Introduction

SILICON BIDIRECTIONAL TRIODE THYRISTOR The TIC226D is a TRIAC (Triode for Alternating Current) manufactured by Texas Instruments (TI). Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Voltage Rating (VDRM/VRRM):** 400V  
- **Current Rating (IT(RMS)):** 8A  
- **Gate Trigger Current (IGT):** 5mA (typical)  
- **Gate Trigger Voltage (VGT):** 1.5V (typical)  
- **On-State Voltage (VTM):** 1.7V (typical at 8A)  
- **Holding Current (IH):** 5mA (typical)  
- **Non-Repetitive Surge Current (ITSM):** 80A (for one half-cycle at 60Hz)  
- **Critical Rate of Rise of Off-State Voltage (dv/dt):** 50V/µs (minimum)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-220AB (isolated tab)  

### **Description:**  
The TIC226D is a high-current TRIAC designed for AC power control applications. It is suitable for switching and phase control in resistive and inductive loads, such as heaters, motors, and lighting systems.  

### **Features:**  
- **High Current Capability:** Supports up to 8A RMS load current.  
- **High Voltage Rating:** 400V blocking voltage for reliable operation in AC mains applications.  
- **Low Gate Trigger Current:** Ensures compatibility with low-power control circuits.  
- **Isolated Tab:** The TO-220AB package has an isolated tab for simplified heatsink mounting.  
- **Snubberless Operation:** Robust dv/dt capability for improved noise immunity.  
- **Sensitive Gate:** Allows for easy triggering with low gate current.  

This information is strictly based on the manufacturer's datasheet and specifications.

Application Scenarios & Design Considerations

SILICON BIDIRECTIONAL TRIODE THYRISTOR

Alternative Part Number

  • 2N6075A --: Sensitive-gate triac in TO-225 package with 400V/4A ratings similar to the TIC226D, widely available and a common drop-in for general AC switching.
  • MAC228A6 --: 400V, 8A triac in TO-220 with comparable gate sensitivity, suitable replacement for the TIC226D in phase-control and load-switching applications.
  • Q4006L4 --: 400V, 6A logic-level triac in TO-220, offers similar current and voltage capability with a different series naming for easy identification.
  • Q4008L4 --: 400V 8A sensitive-gate triac in TO-220, directly replaces the TIC226D in most AC switching circuits with similar gate trigger current.
  • BTA08-400B --: 8A 400V standard triac in TO-220 with isolated tab option, widely available and electrically compatible with TIC226D applications.
  • MAC228A8 --: 8A 400V sensitive-gate triac in TO-220, similar gate characteristics and voltage rating, suitable drop-in for TIC226D.
  • Q4006DH4 --: 400V 6A sensitive-gate triac in TO-220, directly interchangeable with TIC226D for most AC switching applications.
  • BT136-600E --: 600V 4A sensitive-gate triac in TO-220, higher voltage margin and widely available, suitable replacement for low-power triac circuits.
  • MAC97A8 --: 600V 0.8A sensitive-gate triac in TO-92, lower current but usable in light-load gate-trigger circuits where TIC226D is over-specified.
