Frequently Asked Questions
What is the maximum drain-source voltage and drain current of the STD4N80K5?
The STD4N80K5 has a minimum drain-source breakdown voltage of 800V and a maximum continuous drain current of 3A. The maximum drain-source on-resistance is 2.5 ohms, with a typical value of 2.1 ohms, making it suitable for high-voltage, low-to-moderate current power applications.
What technology does the STD4N80K5 use and why does it matter?
The STD4N80K5 uses STMicroelectronics MDmesh K5 superjunction technology, which significantly reduces both on-resistance and gate charge compared to standard MOSFETs. This results in lower conduction and switching losses, improving the efficiency of power converters operating at higher frequencies.
What package does the STD4N80K5 come in?
The STD4N80K5 is housed in a DPAK (TO-252) surface-mount package with the case connection tied to the drain, allowing the device tab to be soldered directly to a PCB copper area for effective thermal management without an external heatsink in many applications.
What is the avalanche energy rating of the STD4N80K5?
The STD4N80K5 has an avalanche energy rating (Eas) of 74.5mJ, indicating its ability to absorb energy during unclamped inductive switching events. This robust avalanche capability improves the reliability and ruggedness of the device in real-world power supply circuits.
What are typical applications for the STD4N80K5?
Typical applications include offline flyback and LLC resonant switch-mode power supplies, industrial power converters, energy-efficient AC-DC adapters, LED lighting drivers, and solar microinverters. The 800V rating and MDmesh K5 technology make it well-suited for designs connected directly to AC mains input stages.
