The 200 µA max gate trigger current lets a low-power microcontroller GPIO or a simple transistor switch fire it directly — no separate driver stage needed for most loads. Housed in the IPAK (TO-251AA) through-hole package with short leads, it mounts into a compact footprint on the board and handles the thermal load of a 5 A average conduction without a heatsink in moderate ambient conditions. ## Current, surge, and temperature envelope Rated 8 A RMS continuous on-state current and 5 A average — the RMS figure governs the resistive heating in the die, so a 5 A DC load or an 8 A half-wave rectified load both stay within the SOA. Non-repetitive surge capability is 70 A at 50 Hz and 73 A at 60 Hz, covering inrush from capacitive or incandescent loads on power-up. Operating temperature spans -40°C to 125°C, which covers industrial enclosures and outdoor equipment. The 5 mA max holding current means the SCR latches reliably once triggered and does not drop out on light loads. ## Gate drive and leakage Gate trigger voltage is 800 mV max, compatible with 3.3 V logic levels through a current-limiting resistor. Off-state leakage is 5 µA max at rated voltage — negligible in most circuits, but worth noting if the load is a high-impedance sensor that sees the leakage as a bias current. On-state voltage drop is 1.6 V max at rated current — this sets the conduction loss. At 5 A average, dissipation is roughly 8 W; a small clip-on heatsink keeps the junction below 125°C in still air.","metaTitle":"ST TS820-600H SCR, 600V 8A IPAK Sensitive Gate","metaDescription":"STMicroelectronics TS820-600H sensitive-gate SCR, 600V off-state, 8A RMS, IPAK through-hole.
