In an era of evolving supply chains, engineers globally are seeking reliable, high-quality alternatives to established high-voltage MOSFETs. If you are considering the STP23N80K5 from STMicroelectronics, meet the strategic upgrade: VBsemi's VBM18R15S.
This is not just a pin-to-pin replacement. The VBM18R15S delivers robust performance with the advantages of a modern, diversified supply source.
Beyond Direct Replacement: Enhanced Application Suitability
While the STP23N80K5 is a proven 800V, 16A N-channel MOSFET with an RDS(on) of 280mΩ, the VBM18R15S is engineered for demanding high-voltage scenarios. Sharing the same 800V drain-source voltage rating and industry-standard TO-220 package, it offers optimized characteristics:
Superior Voltage Ruggedness: Both MOSFETs are rated for 800V, making them suitable for offline power supplies. The VBM18R15S maintains this critical threshold, ensuring reliable operation in universal mains applications.
Balanced Performance for Switching: With a continuous drain current of 15A, it aligns closely with the 16A rating of the STP23N80K5, providing ample current capability for primary-side switching. The gate threshold voltage is compatible, ensuring easy drive with standard controllers.
Advanced Technology Platform: Utilizing a SJ_Multi-EPI structure, the VBM18R15S is designed for high efficiency and low switching losses, which is crucial for high-frequency operation.
Where It Delivers Value: Key Applications
The VBM18R15S excels in applications requiring high voltage and reliability:
Switch-Mode Power Supplies (SMPS): Ideal as the primary switch in AC-DC converters, power adapters, and server PSUs, its 800V rating handles voltage spikes with margin.
Lighting Solutions: Perfect for driving LED stages in high-power industrial and commercial lighting systems.
Industrial Motor Drives & Inverters: Provides a reliable switching solution for auxiliary power stages in motor control and renewable energy systems.
