With a maximum gate trigger current of just 200 µA and gate trigger voltage of 800 mV, this part is designed for direct drive from low-power logic or microcontroller I/O without an intermediate driver stage. ## Parametric highlights for the BOM line The 4 A RMS (2.5 A average) on-state rating suits loads like small solenoids, relays, or incandescent lamps where the RMS current stays under the limit and the 30 A / 33 A non-repetitive surge (50/60 Hz) handles inrush on cold starts. Maximum on-state voltage is 1.6 V at rated current, and the holding current is 5 mA max — low enough to stay latched with light loads but high enough to avoid nuisance turn-off from leakage.","metaTitle":"STMicroelectronics TS420-600H SCR, 600V 4A, Sensitive Gate","metaDescription":"STMicroelectronics TS420-600H SCR, 600V off-state, 4A RMS, sensitive gate (200 µA trigger).
