STP4N150-CN is a 1500 V, 3 A N-channel TO-220C MOSFET intended for high-voltage adapter, charger, and standby SMPS switching applications.

Best for

  • High-voltage offline switching stages
  • Adapters and chargers
  • SMPS standby power

Avoid if

  • Low-loss high-current switching designs
  • Applications requiring verified automotive qualification
  • Designs without adequate high-voltage transient margin

Check before use

  • Confirm drain-source transient voltage remains below the 1500 V rating.
  • Calculate conduction loss using the maximum 8.2 Ω RDS(on) specification.
  • Validate heatsinking against the application case temperature and duty cycle.
  • Confirm availability and lifecycle status with the intended supplier.
