Description and Introduction

4A TRIACS Here are the factual details about part **T435-800B** from the manufacturer **ST**:

### **Manufacturer Specifications**:
- **Manufacturer**: STMicroelectronics (ST)
- **Part Number**: T435-800B
- **Type**: Triac (Bidirectional Thyristor)
- **Voltage Rating (VDRM)**: 800V
- **Current Rating (IT(RMS))**: 4A
- **Gate Trigger Current (IGT)**: Typically 5mA
- **On-State Voltage (VTM)**: Typically 1.7V
- **Critical Rate of Rise of Off-State Voltage (dv/dt)**: ≥50V/µs
- **Operating Temperature Range**: -40°C to +125°C
- **Package**: TO-220AB (isolated tab)

### **Descriptions**:
- The **T435-800B** is a **4A, 800V** triac designed for AC switching applications.
- It is suitable for general-purpose AC load control in appliances, lighting, and motor control.
- The device features **high noise immunity** and **low gate trigger current** for reliable switching.

### **Features**:
- **High Voltage Capability**: 800V blocking voltage.
- **Sensitive Gate**: Low gate trigger current (5mA typical).
- **Isolated Package**: TO-220AB with an isolated tab for easier heatsink mounting.
- **High Commutation (dv/dt)**: Ensures reliable switching in inductive loads.
- **Planar Passivated**: Provides robustness and long-term reliability.

For exact electrical characteristics, refer to the official **ST datasheet** for the T435-800B.
