The through-hole leads provide mechanical strength for point-of-load regulators or modules that see vibration.","metaTitle":"STD5NK40Z-1 N-Channel MOSFET, 400V, 3A, TO-251","metaDescription":"STD5NK40Z-1 N-Channel 400V 3A MOSFET from STMicroelectronics SuperMESH series. 1.8 Ohm Rds(on) at 1.5A, 10V.
