Maximum power dissipation is 40 W, and the Vce saturation is specified at 2 V maximum with a 500 µA base current driving 50 mA collector current — a useful figure for estimating conduction loss in a switching or linear application. The tab is the collector — the heatsink interface needs electrical isolation unless the entire assembly shares the collector potential. Supplied in Tube packaging, which is the standard for through-hole power devices and works well for manual insertion or low-volume assembly.","metaTitle":"STP03D200 NPN Darlington, 1200 V, 100 mA, TO-220","metaDescription":"STMicroelectronics STP03D200 NPN Darlington transistor, 1200 V Vce, 100 mA Ic, 40 W, TO-220-3.
