Its trade-off noise immunity (dV/dt = 1000 V/μs) versus its gate triggering current (IGT = 15 mA) and its turn-on current rise (dI/dt = 200 A/μs) allow to design robust and compact control circuit in AC/DC converters for inrush current limiting circuits and industrial drives, such as overvoltage crowbar protection, motor control circuits and power tools. **DS14781** - **Rev 1** - **September 2024** For further information contact your local STMicroelectronics sales office. www.st.com **TN4015H-8T Characteristics** **1 Characteristics** **Table 1.
