At full 2.5 A load, conduction loss hits about 19 W at 25 °C junction, which eats into the 45 W power dissipation budget — so the thermal design needs a decent heatsink on the TO-220 tab. ## Obsolete — sourcing the STP3LN62K3 today STMicroelectronics lists the STP3LN62K3 as obsolete.","metaTitle":"STP3LN62K3 N-Channel MOSFET, 620 V, 2.5 A, TO-220","metaDescription":"STP3LN62K3 N-Channel MOSFET, 620 Vdss, 2.5 A continuous drain, 3 Ohm Rds(on) at 10 V.
