That is a standard drive level — most optocoupler or pulse-transformer gate drivers will fire it cleanly. Holding current is 75 mA max, which means the SCR stays latched once triggered as long as the load current stays above roughly 75 mA. Below that, it drops out. For resistive loads that pull a few amps, no issue; for a lightly loaded phase-control leg, check your minimum load current against that 75 mA threshold. ROHS3 compliant, so it passes current European and Asian material restrictions.","metaTitle":"STMicroelectronics TYN640RG SCR, 600V 40A TO-220, Active","metaDescription":"TYN640RG SCR from STMicroelectronics: 600V off-state, 40A RMS on-state, 480A surge.
