TOPT12-800C0,127

Thyristors - TRIACs

A Triac, also known as a Thyristor, is a three-terminal semiconductor device which is used in power switching circuits. Triacs are well suited for applications in which high-speed switching is required, such as phase control circuits, motor speed controls, light dimming and relay switching. At its most basic, a Triac functions as an on/off switch, allowing current to flow in either direction through the device when it is turned “on”.

TOPT12-800C0,127 Application Field and Working Principle

The TOPT12-800C0,127 is a Triac from Tyco Electronics which is designed for applications requiring high-speed switching and the ability to withstand high-voltage, moderate current conditions. It is widely used in phase control circuits, light dimmers, motor speed controls, relay switching and other applications requiring high-speed switching or light dimming control. The TOPT12-800C0,127 is typically used to turn “on” and “off” electrical power in circuits. It functions as an “on/off” switch, allowing current to flow in either direction through the device when it is turned “on”. When the Triac is turned “off”, it blocks the flow of current in either direction.

The TOPT12-800C0,127 Triac has a trigger voltage of 600V and a trigger current of 500mA. It is rated for a peak repetitive off-state voltage of 800V, with a surge current rating of 200A. It is designed with a maximum blocking voltage of 800V, with a maximum on-state current of 12A. The Triac is also designed with a minimum operating temperature of -40°C and a maximum operating temperature of 125°C. The device has a maximum junction temperature of 150°C.

The TOPT12-800C0,127 Triac is a bidirectional device that has three main characteristics; blocking, triggering and conduction. Blocking mode is the Triac’s off state, in which it blocks current flow in both direction when its terminals are forward biased. Triggered mode is the Triac’s on state in which current flows in either direction when its terminals are forward biased. The amount of current that can flow through the device is limited by its conduction rating. The device’s gate terminal can be used to control the on/off switching and to control the device’s conduction. The gate terminal of the device can be triggered using a logic voltage or a pulse generated by an associated control circuit.

In summary, the TOPT12-800C0,127 Triac from Tyco Electronics is a three-terminal semiconductor device which is designed for applications requiring high-speed switching and the ability to withstand high-voltage and moderate current conditions.
