The 20 mA maximum holding current means the SCR will stay latched once triggered as long as the load current stays above that threshold; below 20 mA the device turns off naturally at the next zero-crossing.","metaTitle":"STMicroelectronics TYN612MRG SCR, 12 A RMS, 600 V, TO-220-3","metaDescription":"Standard recovery SCR, 12 A RMS / 8 A average, 600 V off-state, 5 mA gate trigger.
