For the reflow profile, this is a standard leaded surface-mount package — no exotic profile required, but the tab's solder coverage matters for thermal performance.","metaTitle":"STDLED656 N-Channel MOSFET, 650 V, 6 A, DPAK","metaDescription":"STMicroelectronics STDLED656 N-Channel MOSFET, 650 Vdss, 6 A continuous drain, 1.3 Ohm Rds(on) at 10 V.
