The NXP BT139 Series Triacs, specifically the BT139-800E and BT139-600E, are highly versatile and robust semiconductor devices designed for use in AC power control applications. These triacs allow for control of large power flows with milliampere-scale control currents, making them an ideal choice for a wide range of applications such as motor control, domestic lighting, heating, and static switching.

Key Features

• High Blocking Voltage: The BT139-800E is rated for a maximum repetitive peak off-state voltage (VDRM) of 800V, while the BT139-600E has a VDRM of 600V, making them suitable for mains voltage applications.
• High Surge Current: These triacs can handle high surge currents, providing robust performance in applications where inrush currents can be significant.
• Sensitive Gate: Both devices feature a sensitive gate that allows triggering by low-power gate drivers and microcontrollers, facilitating their use in digital control schemes.
• Quadrant Operation: They are capable of operation in all four quadrants, ensuring reliable triggering in both AC half-cycles.

Applications

• Motor Speed Controllers
• Domestic Lighting Dimmers
• Electric Heaters
• Small Home Appliances
• Industrial Process Control Equipment

Package and Mounting

Both the BT139-800E and BT139-600E are available in a TO-220AB package, which is widely used for medium power applications. The package is designed for through-hole mounting, which simplifies the assembly process and provides a robust mechanical and electrical connection.
