T1901N80TOHXPSA1

Overview

The T1901N80TOHXPSA1 is a high-power Silicon SCR module manufactured by Infineon Technologies, designed for demanding industrial applications. It features an 8 kV rated repetitive off-state voltage (VDRM) and supports a non-repetitive on-state peak current of 45 kA. The device operates within a junction temperature range of -40°C to +125°C and utilizes a press-fit installation style in the T-15035K package. Key electrical parameters include a maximum holding current of 350 mA, a gate trigger voltage of 2.5 V, and a gate trigger current of 350 mA. The module exhibits a maximum off-state leakage current of 500 mA at VDRM and has a rated continuous current of 2.8 A.
