Thyristors - TRIACs offer many useful advantages when it comes to controlling electrical currents. The T1250H-6T is a type of TRIAC that is used for various applications, such as motor speed control, lamp dimming, and other AC switching applications.

The T1250H-6T is a trigger gate ideal for applications that require a high gate current rating. It features a high surge current capability as well as a high load current rating, making it well-suited for AC load switching applications. The T1250H-6T is designed to require only a minimal external gate current to begin and sustain conduction. It is an inherently bidirectional device and can be used in both AC and DC switching applications.

Application Field of T1250H-6T
The T1250H-6T is primarily used for motor speed control and lamp dimming purposes in AC applications. This device offers excellent efficiency and low switching losses for motor speed and lamp dimming applications. It is also used for various applications such as AC load switching, over-voltage protection, and solenoid control.

Due to its wide range of characteristics, the T1250H-6T is used in many consumer applications, such as dimmer switches, electric ovens, and induction motors. It can also be used in special applications such as auto-layer-control and heat PWM systems, as well as in industrial applications like speed management and lighting systems.

Working Principle of T1250H-6T
The T1250H-6T operates on the principle of four-layer AC solid-state switches or TRIACs. The device consists of two main regions; the main part is referred to as the “Anode-gate region” and the other the “cathode-gate region”. To begin the conduction, the gate current needs to be applied to TRIAC. When current flows through the Anode-gate region, it can induce a current flow in the cathode-gate region, thus allowing the T1250H-6T to switch on. The current in the cathode-gate region also removes any traps that prevent the TRIAC from turning off.

The T1250H-6T has an on-state voltage drop of 46 V and an on-state current of up to 30 Amp. It can handle a maximum peak current of up to 220 Amp. The maximum gate current for a TRIAC is typically in the range of 20-30 mA. This is because if the gate current becomes too high, it can destroy the gate and damage the TRIAC.

The T1250H-6T is a double-sided TRIAC and can be used as both an AC switch and a DC switch. It is designed to let very little current flow during the OFF state and has a very low leakage current when the TRIAC is in the OFF state. The T1250H-6T can be used in a variety of applications such as motor speed control, lamp dimming, and other AC switching applications. It offers fast switching times, excellent thermal performance, and good reliability.

The T1250H-6T is a reliable and efficient device for AC and DC applications. It is commonly used in consumer, industrial and special applications and requires minimal external gate current for switching. It is capable of handling high surge currents and has low on-state voltage drop, offering excellent efficiency and low switching losses for various applications. The device is also designed for safety and reliability, making it a great choice for many different applications.
