Overview

Description

The STW42N65M5 is a 650V, 42A N-channel MOSFET from STMicroelectronics, designed for high-efficiency power applications. Key features include:
- Low On-Resistance (RDS(on)): 42mΩ (max) at 10V, reducing conduction losses.
- Fast Switching: Optimized for high-frequency operations like SMPS, motor drives, and inverters.
- Avalanche-Rugged: Enhanced reliability under harsh conditions.
- Low Gate Charge (Qg): Improves switching efficiency.
Packaged in TO-247, it suits industrial and automotive systems requiring high power density. Its low thermal resistance ensures effective heat dissipation.
Ideal for:
- Switch-mode power supplies (SMPS).
- Solar inverters.
- Motor control.
For detailed specs, refer to the datasheet.
