BT131 TO-92 TRIAC

The BT131 is TRIAC with 1 A maximum terminal current. The gate threshold voltage of the BT131 is also very less so can be driven by digital circuits.

Since TRIACs are bi-directional switching devices they are commonly used for switching AC applications. To switch off control of an AC load that consumes less than 3A with a digital device like a microcontroller or microprocessor then BT131 is the best choice.

Pin Configuration:

• Main Terminal 1 (Pin 1) : Connected to Phase or neutral of AC mains
• Main Terminal 2 (Pin 2) : Connected to Phase or neutral of AC mains
• Gate (Pin 3) : Used to trigger the SCR.

Features:-

• It has a highly sensitive gate
• It is suitable for uses in mains appliance control
• BT131 is a 1 amp which can be used as like switch for your home electric appliance which is of 1.5 V operated We can use it to control the switch of your fan, led light.

Limitation:-

• Commutation is not required in AC switching circuits because the TRIAC will not latch on the state since the AC voltage reaches zero for every half cycle.

Applications:-

• AC Light dimmers
• Strode lights
• AC motor speed control
• Noise coupling circuits
• Controlling AC loads using MCU/MPU
• Ac/DC Power control
• Light dimmers
• Washing machines
• Motor control
• Hand tools
