The STMicroelectronics STD60NH03LT4 is an N-channel power MOSFET built on the STripFET™ III process, a generation tuned for low on-resistance per unit area. The DPAK (TO-252-3) surface-mount package keeps the footprint compact while the tab provides a thermal path to the board copper.
The drive voltage range is specified between 5 V and 10 V. Gate charge is 21 nC at 5 V. The maximum threshold voltage is 1 V at 250 µA drain current.
The date-code and lot traceability should be verified on any material sourced outside the authorized chain — the DPAK package marking and laser etch font are consistent across ST's production, so a mismatch is a red flag.
