概述

Description

STB45N65M5 is a high-voltage N-channel power MOSFET from STMicroelectronics (STB family). It’s designed for switching applications in power electronics (offline SMPS, PFC, motor drives, inverters).
Key points:
- Voltage/current: VDS around 650 V; continuous ID about ~45 A (depends on package and cooling).
- Technology: Trenched N-channel MOSFET with relatively low RDS(on) for a 650 V device; good switching performance.
- Drive and protection: Gate threshold typically 2–4 V; intended for gate drive around 10–12 V; avalanche ruggedness and robust SOA characteristics.
- Packages: Available in surface-mount options such as D²PAK (TO-263) and DPAK variants.
- Applications: Power supplies, motor drives, inverters, and other high-voltage switching circuits.
Note: For exact electrical parameters (RDS(on), Qg, SOA, thermal specs) and packaging, consult the latest ST datasheet.

Features

STB45N65M5 is an STMicroelectronics 650 V N-channel power MOSFET. Key features:
- 650 V blocking voltage
- 45 A continuous drain current
