Description and Introduction

4A TRIACS The part **T405-600B** is manufactured by **STMicroelectronics (ST)**.  

### **Specifications:**  
- **Type:** Triac (bidirectional thyristor)  
- **Voltage Rating:** 600V  
- **Current Rating:** 4A (RMS)  
- **Gate Trigger Current (I_GT):** 5mA (typical)  
- **On-State Voltage (V_T):** 1.7V (typical)  
- **Holding Current (I_H):** 5mA (typical)  
- **Critical Rate of Rise of Off-State Voltage (dv/dt):** 50V/µs (minimum)  
- **Isolation Voltage:** 2500V RMS  
- **Package:** TO-220AB (isolated tab)  

### **Descriptions:**  
The **T405-600B** is a **4A, 600V** triac designed for general-purpose AC switching applications. It is suitable for controlling resistive or inductive loads in appliances, lighting, and motor control circuits.  

### **Features:**  
- **High Commutation Capability**  
- **Low Gate Trigger Current**  
- **Isolated Package (TO-220AB)** for easier mounting  
- **Snubberless Design** (resistant to voltage spikes)  
- **Suitable for 50/60Hz AC mains applications**  
- **RoHS Compliant**  

This triac is commonly used in dimmers, relays, and solid-state switching circuits.
