Frequently Asked Questions
What is the STL45N65M5 and what are its voltage and current ratings?
The STL45N65M5 is an N-channel Power MOSFET from STMicroelectronics using MDmesh M5 technology, rated for a 650V minimum drain-source breakdown voltage and a maximum drain current of 22.5A. With a typical on-resistance of 75 mΩ and a maximum of 86 mΩ, it delivers excellent conduction performance for high-voltage power conversion applications.
What makes the MDmesh M5 technology in the STL45N65M5 advantageous?
The MDmesh M5 technology in the STL45N65M5 is STMicroelectronics' advanced superjunction MOSFET process that achieves a superior balance between on-resistance and gate charge. This results in a low figure of merit (Ron × Qg), reducing both conduction and switching losses simultaneously. The 7 pF maximum feedback capacitance (Crss) also minimizes Miller effect and supports operation at high switching frequencies in resonant and PWM converters.
What is the avalanche energy rating of the STL45N65M5 and why does it matter?
The STL45N65M5 has an avalanche energy rating (Eas) of 810 mJ, which indicates its ability to absorb energy during unclamped inductive switching events without damage. This high avalanche ruggedness is important in hard-switched power supply topologies where voltage spikes from leakage inductance can momentarily exceed the device breakdown voltage, ensuring reliable operation in real-world power conversion environments.
What package does the STL45N65M5 use and how does it aid thermal management?
The STL45N65M5 is housed in a PowerFLAT 8x8 HV package with the case connected to the drain terminal. This surface-mount package features a large exposed copper pad on the bottom that enables direct thermal contact with the PCB, significantly improving heat dissipation compared to traditional leaded packages. The compact 8x8 mm footprint supports high power density designs in adapters, inverters, and industrial power modules.
What are typical applications for the STL45N65M5?
The STL45N65M5 is commonly used in AC-DC power supplies, PFC boost converters, LLC resonant half-bridge and full-bridge topologies, and industrial motor drives. Its 650V rating makes it compatible with universal mains input (85V to 265V AC) power conversion, and the MDmesh M5 technology's high efficiency is particularly valued in server PSUs, telecom rectifiers, solar micro-inverters, and EV on-board charging systems.
