STMicroelectronics Thyristor SCR 800 V 8 A TO-220 Package TYN812RG

STMicroelectronics TYN812RG is a Silicon Controlled Rectifier (SCR) thyristor specifically engineered for electronic power switching with robust electrical characteristics. This device is rated for a repetitive peak reverse voltage of 800 V and an average on-state current of 8 A, ideal for moderate power applications requiring efficient control and protection.

The TYN812RG comes in a TO-220 package with a three-pin interface that supports through-hole mounting on printed circuit boards. It features a maximum surge current rating of 145 A, making it capable of handling brief high current conditions safely without damage.

The thyristor operates reliably across a wide temperature range from -40°C up to 125°C, ensuring performance stability under diverse environmental conditions. The maximum gate trigger current of 15 mA allows for sensitive activation while maintaining a maximum holding current of 30 mA to prevent unintended turn-off.

With a peak on-state voltage drop of 1.6 V, the device exhibits low conduction losses, making it energy efficient in high-frequency switching scenarios. The TYN812RG is not specifically designed to meet automotive standards and does not carry any particular certifications.

This thyristor is suitable for use in industrial power supplies, motor controls, heating controls, and other power electronic circuits requiring reliable SCR switches with TO-220 packaging.

Key technical features of the TYN812RG include its SCR construction, through-hole mount type, and 3-pin configuration optimized for easy integration into power control systems. Repetitive Peak Reverse Voltage of 800 V for high-voltage resilience.

Surge Current Rating of 145 A supporting transient overcurrent conditions. Maximum Gate Trigger Current of 15 mA facilitating sensitive conduction control. Operating temperature range from -40°C to 125°C for robust thermal performance.

Peak On-State Voltage of 1.6 V to reduce power dissipation. Package Type TO-220 with 3 pins for simplified mounting.
