Housed in a TO-92-3 through-hole package (TO-226AA), it suits wave-solder or hand-assembly on single-sided boards. The 5 mA max holding current keeps the SCR latched under light loads typical of relay coils, solenoid valves, or small incandescent lamps. With a 1.95 V max on-state voltage at 800 mA RMS, conduction loss runs about 1.6 W — the TO-92 package dissipates that in free air at 25°C ambient; at 125°C junction limit the current must be derated. The 8 A non-repetitive surge capability (60 Hz, one cycle) handles capacitive inrush or cold-filament loads without exceeding the die's surge rating. Off-state leakage is 10 µA max at rated voltage — negligible in most circuits. ## Active production, ROHS3 compliant — sourcing posture ROHS3 compliance (2011/65/EU + 2015/863) covers all six original substances plus the four phthalates. Supplied in Bag packaging — loose units, not tape-and-reel. That signals a low-volume or prototyping inventory profile. For production quantities, confirm the packaging preference (tube or ammo pack) at quote time.","metaTitle":"ST P0102DA 1AA3 SCR, 400V 800mA Sensitive Gate TO-92","metaDescription":"STMicroelectronics P0102DA 1AA3 Sensitive Gate SCR, 400V off-state, 800mA RMS, 200µA gate trigger.
