Non-repetitive surge current is 100 A at 50 Hz and 105 A at 60 Hz (half-cycle), which covers motor inrush and capacitive loads typical in phase-control circuits like light dimmers and heater controllers. ## Gate drive and hold current — what the driver needs Maximum gate trigger current is 15 mA, with a maximum gate trigger voltage of 1.5 V. The holding current is 30 mA maximum. These numbers are compatible with standard logic-level gate drivers or a simple resistor-limited DC trigger from a microcontroller I/O pin — just ensure the gate pulse amplitude and duration exceed the Igt threshold to guarantee turn-on over temperature. Off-state leakage is 10 µA maximum, which is negligible for most line-frequency loads but worth noting if the load impedance is very high (e.g., a bleeder resistor in a snubber network). The TO-220-3 package is through-hole, so it mounts to a heatsink with a screw or clip — the tab is the anode connection, so insulate the heatsink or use a mica washer if the heatsink is grounded.","metaTitle":"STMicroelectronics TYN410RG SCR, 400 V 10 A TO-220, Obsolete","metaDescription":"STMicroelectronics TYN410RG standard recovery SCR, 400 V off-state, 10 A RMS, TO-220-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Series":"-","Package":"Tube","SCR Type":"Standard Recovery","Mounting Type":"Through Hole","Package / Case":"TO-220-3","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"TYN410","Voltage - Off State":"400 V","Operating Temperature":"-40°C~125°C","Supplier Device Package":"TO-220","Current - Hold (Ih) (Max)":"30 mA","Current - Off State (Max)":"10 µA","Voltage - On State (Vtm) (Max)":"1.6 V","Current - Gate Trigger (Igt) (Max)":"15 mA","Current - On State (It (AV)) (Max)":"6.4 A","Voltage - Gate Trigger (Vgt) (Max)":"1.5 V","Current - On State (It (RMS)) (Max)":"10 A","Current - Non Rep.
