The NXP BT134-800E is a passivated, sensitive gate triac in a plastic package intended for use in general purpose bidirectional switching and phase control applications. This triac, which is part of the BT134 series, is designed to interface directly with low power drivers like microcontrollers. With its sensitive gate, the BT134-800E can be driven by low current gate signals, making it a versatile choice for a wide range of applications.

Key Features

• Blocking Voltage: Capable of blocking voltages up to 800V, making it suitable for use in circuits with high AC line voltages.
• On-State Current: It can handle an RMS on-state current of up to 4 A, which is adequate for controlling moderately sized loads.
• Sensitive Gate: The sensitive gate allows triggering by microcontrollers’ logic level outputs or other low-power gate drive circuits.
• Package: Enclosed in a compact D-Pak (TO-252) plastic package, it is designed for surface mount applications, providing space-saving benefits.

Applications

The BT134-800E is suitable for a variety of applications, including:

• Motor control circuits
• Domestic lighting and heating
• Small home appliances
• Industrial process control devices
• Static switching relays
