STP20NM50FP Description

The STP20NM50FP from STMicroelectronics is an N-channel 550V power MOSFET designed for high-voltage switching applications. Part of the MDmesh™ series, it leverages advanced Metal Oxide (MOSFET) technology to deliver low on-state resistance (250mΩ @ 10A, 10V) and high efficiency. With a continuous drain current (Id) of 20A (Tc) and a power dissipation of 45W (Tc), it balances performance and thermal management. The device features a TO220FP package for through-hole mounting, ensuring robust mechanical and thermal stability.

STP20NM50FP Features

• High Voltage Rating: 550V Vdss for demanding industrial and power applications.
• Low Gate Charge (Qg): 56nC @ 10V minimizes switching losses, improving efficiency.
• Fast Switching: Optimized input capacitance (Ciss: 1480pF @ 25V) for reduced transition times.
• Enhanced Thermal Performance: TO220FP package with improved heat dissipation.
• Wide Drive Voltage Range: Vgs(max) ±30V with a threshold (Vgs(th)) of 5V @ 250µA, ensuring compatibility with various drivers.
• Reliability: ROHS3 compliant, REACH unaffected, and MSL 1 (Unlimited) for long-term durability.
