## **Description** 

Thanks to its operating junction temperature up to 150°C, the TN1605H-8T offers high thermal performance operation up to 16 A rms in a TO-220AB package. 

Its trade-off noise immunity (dV/dt = 500 V/μs) versus its gate triggering current (maximum IGT = 8 mA) and its turn-on current rise (dI/dt = 100 A/μs) allows 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.
