STL8N80K5

STL8N80K5 Description

The STL8N80K5 from STMicroelectronics is a high-performance N-channel MOSFET designed for demanding power applications. Built using SuperMESH5™ technology, it offers an impressive 800V drain-to-source voltage (Vdss) and a continuous drain current (Id) of 4.5A at 25°C (case temperature). With a low on-resistance (Rds(on)) of 950mΩ at 10V gate drive, this MOSFET ensures efficient power handling while minimizing conduction losses. The device is housed in a compact PowerFlat™ (5x6) surface-mount package, making it ideal for space-constrained designs.

STL8N80K5 Features

• High Voltage & Low Losses: Optimized for 800V applications with SuperMESH5™ technology, reducing switching losses and improving thermal performance.
• Fast Switching: Low gate charge (Qg) of 16.5nC and input capacitance (Ciss) of 450pF enable high-frequency operation.
• Robust Design: ±30V gate-source voltage (Vgs) tolerance enhances reliability in harsh environments.
• Efficient Thermal Management: 42W max power dissipation (Tc) ensures stable operation under high loads.
• Industry Compliance: ROHS3 compliant, REACH unaffected, and MSL1 (unlimited) rated for extended shelf life.
