ST TYN1225

Part points

• The TYN1225 is an electrical component known as a TRIAC, which stands for "Triode for Alternating Current." It is a high-voltage device commonly used in controlling AC power in various applications such as light dimming, motor speed control, and heating control systems. The TYN1225 chip specifically is designed to handle currents up to 25A and voltage ratings up to 600V.

• Features

  The TYN1225 is a silicon controlled rectifier (SCR) with a voltage rating of 1200 V and a current rating of 25 A. It has a low holding current for reliable operation, high surge current capability, and high noise immunity. It also features a glass-passivated junction to ensure high reliability and a planar structure for easy mounting.

• Pinout

  The TYN1225 is a 25A sensitive gate SCR transistor. It has three pins: anode (A), cathode (K), and gate (G). The anode is connected to the load, the cathode is at the ground potential, and the gate is used to trigger the SCR.

• Manufacturer

  The manufacturer of the TYN1225 is STMicroelectronics. It is a multinational electronics and semiconductor company headquartered in Switzerland. STMicroelectronics designs, develops, and manufactures a wide range of semiconductor products for various industries including automotive, industrial, personal electronics, telecommunications, and more.

• Application Field

  The TYN1225 is a silicon-controlled rectifier (SCR) primarily used in power control applications, such as in dimmer switches for lighting systems, AC voltage regulation, motor control, and in soft-start circuits for power tools and appliances. It is also employed in industrial heating, power supplies, and electric vehicle charging systems.

• Package

  The TYN1225 chip has a TO-220AB package type, through-hole form, and a standard size.
