Gate trigger current is 15 mA max, which means a standard MOC30xx or similar optocoupler can fire it directly — no intermediate driver stage needed. ## 4 A RMS continuous — thermal budget in a TO-220 The 4 A RMS (2.5 A average) on-state rating is the continuous load ceiling. In a TO-220 package, the junction-to-case thermal resistance sets the practical limit: at 4 A RMS with a 1.8 V Vtm drop, conduction losses run about 7.2 W. That needs a heatsink with a thermal resistance below 10 °C/W to keep Tj under 125 °C at a 25 °C ambient. The non-repetitive surge rating of 63 A at 50 Hz (60 A at 60 Hz) covers capacitive inrush or short-duration overloads — the die absorbs that energy for one cycle without failing. ## Active production — no LTB scramble needed No end-of-life notice, no last-time-buy deadline to track. The ROHS3 compliance means it ships without any of the six restricted substances plus the four phthalates, so it passes EU material declarations without a waiver.","metaTitle":"STMicroelectronics TYN804RG SCR, 800 V 4 A, TO-220-3","metaDescription":"STMicroelectronics TYN804RG standard recovery SCR. 800 V off-state, 4 A RMS, 15 mA gate trigger.
