~~ea~~| |---|---| |**IT(RMS)**|80 A| |**VDRM/VRRM**|800 V| |**IGT**|50 mA| |**Tj**|150 °C| ## **Description** Available in through hole package TO-247, the TM8050H-8W is an 800 V SCR thyristor suitable for applications where high power switching (IT(RMS) = 80 A) and low power dissipation (VTM = 1.55 V at 160 A) are key features. These features make it ideal for motorbike voltage regulator, by-pass AC switch, controlled rectifier bridge, solid state relay, battery charger, welding equipment and motor driver applications. **DS11583** - **Rev 2** - **August 2019** For further information contact your local STMicroelectronics sales office. www.st.com **TM8050H-8W Characteristics** **1** ## **Characteristics** ## **Table 1.
