Technical Specifications

The RU1E002SP typically has a drain-source voltage (Vds) rating of -12V. The gate-source voltage (Vgs) is typically ±8V. The continuous drain current (Id) is typically -2A. The on-resistance (Rds(on)) is typically around 0.1 ohms (100 milliohms) at Vgs = -4.5V. The gate threshold voltage (Vgs(th)) is typically around -1.0V. It is available in a small SOT-23 package or similar. Consult the Rohm Semiconductor datasheet for detailed specifications and application notes, including thermal considerations and safe operating area.

Careful consideration should be given to the gate drive circuitry to ensure proper and efficient switching. Also, proper heat sinking may be necessary depending on the operating conditions to maintain the MOSFET within its safe operating temperature range.
