The STP95N2LH5 is an N-Channel MOSFET from STMicroelectronics' STripFET™ V series, housed in a through-hole TO-220-3 package. The device is designed for low-voltage, high-current switching applications such as DC-DC converters, load switches, and motor-drive output stages, where conduction loss and thermal performance are critical.
The 13.4 nC typical gate charge at 5 V means the gate-drive energy per switching cycle is low, keeping driver losses in check even at moderate frequencies. The drive voltage range of 5 V to 10 V allows use with both 5 V logic-level gate signals and standard 10 V gate drives, but the Rds(on) at 5 V will be higher than the 4.9 mOhm figure quoted at 10 V — check the typical output characteristics in the datasheet to size the heatsink for the actual gate voltage in your design.
