Housed in a TO-220-3 through-hole package, it suits designs where a soldered, board-mounted thyristor is preferred over a press-fit or surface-mount alternative. ## Gate drive and latching margins Maximum gate trigger current is 25 mA with a 1.5 V gate trigger voltage — a standard logic-level or small-signal transistor can drive the gate directly without a separate driver stage. The 45 mA maximum holding current means the SCR stays latched once triggered until the load current drops below that threshold; in a resistive load, the supply must be interrupted or commutated to turn off. ## Surge rating and thermal headroom Non-repetitive surge current is 80 A at 50 Hz and 84 A at 60 Hz — this covers capacitor inrush or short-duration fault events without exceeding the junction's thermal capacity. RoHS3 compliant (2011/65/EU plus amendment 2015/863), which covers the European regulatory requirement for lead-free and restricted-substance content.","metaTitle":"STMicroelectronics TYN058RG SCR, 50 V 8 A, TO-220","metaDescription":"STMicroelectronics TYN058RG standard-recovery SCR. 50 V off-state, 8 A RMS on-state, 84 A surge.
