It comes in a TO-251-3 (IPAK) through-hole package, suited for compact PCB mounting where a tab-heatsink interface is available. Typical applications include AC motor speed controls, lighting dimmers, inrush current limiters, and general-purpose AC switching in industrial and appliance power stages. The -40°C to 110°C operating range covers most indoor and outdoor telecom enclosures, though it stops short of full automotive under-hood temperature. ## Package and mounting — TO-251 IPAK The TO-251 (IPAK) package has three short leads and a metal tab that is electrically common with the middle pin (anode). The tab is designed for soldering to a PCB copper pad or for a small clip-on heatsink. Through-hole mounting keeps it mechanically robust in high-vibration environments like motor drives or pumps. The 100 µA maximum off-state leakage at 400 V is typical for a standard-recovery SCR in this voltage class; no fast-recovery or soft-recovery characteristics are specified. No end-of-life notification or last-time-buy window is on record.","metaTitle":"TN22-1500H SCR, 400V 2A RMS, TO-251 IPAK, Active","metaDescription":"Standard recovery SCR rated 400 V off-state, 2 A RMS, 1.5 mA Igt.
