STMicroelectronics TYN058 Thyristor

The TYN058 from STMicroelectronics is a robust and reliable silicon-controlled rectifier (SCR) designed to manage medium power. This thyristor is well-suited for applications requiring phase control in AC loads, overvoltage crowbar protection, motor control circuits, and inrush current limiting circuits. It is a versatile component that can be used in a variety of industries including lighting, motor drive, and power supply systems.

With a high surge capability, the TYN058 is capable of handling peak currents with ease, making it an excellent choice for applications that experience occasional short-term overloads. Its on-state RMS current is rated at 8A, which allows it to handle significant steady-state power levels. The device can withstand a maximum repetitive peak reverse voltage of 600V, which ensures it can be used in many different circuit configurations without risk of breakdown.

The TYN058 features a gate trigger current of 15mA, which means it can be triggered into conduction with a relatively small current, making it compatible with a wide range of control circuits and easy to interface with microcontrollers and other logic devices. Additionally, the holding current of the device is low, ensuring that once the current drops below a certain level, the device will turn off automatically, helping to prevent unwanted power dissipation.

Designed with practicality in mind, the TYN058 comes in a TO-220AB package, which is a widely used and easily mountable form factor. This package provides good thermal and mechanical characteristics, allowing the SCR to operate reliably even under harsh conditions. The device also features high immunity to dV/dt, which ensures stable operation during rapid voltage changes that are commonly found in industrial environments.

Overall, the TYN058 is a high-performance SCR that offers a combination of high surge capability, easy gate triggering, and robust thermal properties. Its reliability and versatility make it an excellent choice for designers and engineers looking to create efficient and durable power control systems.
