STMicroelectronics TYN810 SCR

The TYN810 from STMicroelectronics is a robust and reliable silicon-controlled rectifier (SCR) designed to manage a wide range of AC loads in industrial applications. This SCR is a key component in circuits where high surge capability and high immunity to harsh environments are required. It is particularly suitable for applications such as phase control operations in converters, inrush current limiting circuits, and as a bypass switch in SMPS (Switched-Mode Power Supplies).

Key Features

• Voltage Capacity: The TYN810 is capable of withstanding voltages up to 800V, making it suitable for a variety of industrial applications.
• Current Rating: It has a current rating of 10A, ensuring it can handle significant power levels.
• High Surge Capability: This SCR can withstand surge currents, thus providing robust performance during short-term overloads.
• Gate Trigger Current: The device features a gate trigger current of 15mA to 25mA, which is the typical range required to switch the SCR from the off-state to the on-state.
• Low Holding Current: The holding current of the TYN810 is low, which helps prevent unwanted triggering due to noise or fluctuating power conditions.
• Thermal Resistance: The SCR has a junction to case thermal resistance of 1.2°C/W, contributing to its ability to manage heat efficiently.

Applications

• Motor control circuits
• Overvoltage crowbar protection
• Capacitive discharge ignitions
• Voltage regulation circuits
• Industrial power tools
• Home appliances
