- Motor control circuits  
- Load switching  

For exact values (e.g., RDS(on) at specific VGS), refer to the official **STM datasheet**.

Application Scenarios & Design Considerations

N-CHANNEL 30V

Alternative Part Number

  • IRLML6344TRPBF --: N-channel logic-level MOSFET in SOT-23 with comparable 30V rating and low on-resistance, suitable drop-in replacement for low-side switching.
  • FDS6690A --: 30V N-channel MOSFET in SO-8 with similar current capability and low RDS(on), widely available alternative for power switching applications.
  • AO3400A --: 30V logic-level N-channel MOSFET in SOT-23, low gate threshold and low RDS(on), good fit for similar load-switch and DC-DC use.
  • FDS4935A --: P-channel MOSFET in SO-8 with comparable voltage and current ratings, widely available and pin-compatible for many switching applications.
  • SI4435DY --: P-channel MOSFET in SO-8 with similar RDS(on) and voltage rating, a common drop-in alternative for load switch and power management designs.
  • IRF7416 --: P-channel MOSFET in SO-8 rated at -30V with low on-resistance, suitable replacement when layout and gate drive conditions match.
