T835T-8FP

Thyristors - TRIACs

T835T-8FP is a Thyristors - TRIACs device designed to provide solutions in power control applications. It is a six-pin bi-directional triode AC power switch. This device has a wide range of voltage ratings and current ratings in order to offer various options for different applications.

The main electrical characteristics of the T835T-8FP include high control current, with a minimum value of 10mA; an operating temperature range from -40 to +125°C; and a peak repetitive off-state voltage range up to 800V.

The main features of the T835T-8FP are:

• Compact design;
• High blocking voltage;
• Low control current;
• Low firing angles;
• Low leakage current;
• Low standby power dissipation;
• High thermal and electrical stability.

T835T-8FP is mainly used in motor control applications, such as temperature and speed control in industrial processes. It can also be used in domestic applications, such as dimmer control of light bulbs, heating and cooling systems, etc.

The working principle of T835T-8FP is straightforward and consists of controlling the passage of electric current through the main terminals of the device. It has two sets of control terminals: one for positive gate control and another for negative gate control. The positive gate control is used to allow current to flow from the positive main terminal to the negative main terminal, and vice versa for the negative gate control.

The control current of the T835T-8FP is measured as the gate current, which is the amount of current required to activate the device and allow current between the main terminals. The T835T-8FP has a high control current of 10mA, which is the minimum control current needed to open and close the device.

T835T-8FP also has a variable firing angle range which allows for precise power control and precise operation of the device. The variable firing angle is controlled by the amount of gate current passing through the control terminals.

The T835T-8FP is also designed to prevent a phenomenon called “false triggering”, where the device unexpectedly switches into conduction mode, allowing current through the main terminals regardless of the gate current. This is prevented by establishing maximum and minimum control current thresholds, beyond which the device will not open or close.

Thus, the T835T-8FP is a valuable tool for power control applications as it has a wide range of voltage ratings, high control current, and reliable performance. With its features, this device is suitable for a wide range of AC power applications.
