STL57N65M5-VB Product details
Back to previous pageProduct introduction：
** Are you designing a high-efficiency switching power supply but facing challenges with high-voltage losses and heat dissipation? Ordinary MOSFETs either lack sufficient voltage rating or have high on-resistance, making it difficult to control overall temperature rise. The VBsemi STL57N65M5-VB is designed for this – it integrates 650V withstand voltage, 20A current capability, and an on-resistance of only 160mΩ into a compact DFN8X8 package, combined with super-junction multi-epitaxial technology (SJ_Multi-EPI), allowing high-voltage, high-power designs to balance performance and reliability.**

Domain and module applications：
- **Switching Power Supplies/Adapters** – As a high-voltage main switch, effectively reduces conduction losses, improving overall efficiency.
- **PFC Power Factor Correction** – Utilizes the low Qg and low RDS(on) of the super-junction structure to improve current waveform and reduce EMI.
- **Electric Vehicle Chargers** – 650V withstand voltage combined with robust heat dissipation handles wide input voltage and harsh loads.
- **Photovoltaic Inverters** – Operates stably in high-voltage DC-DC boost or inverter bridges, improving system reliability.
- **Industrial Auxiliary Power Supplies** – Wide voltage range and low conduction losses, suitable for long-term continuous operation scenarios.
- **High-Voltage DC-DC Converters** – Replaces traditional high-voltage MOSFETs, reducing switching and conduction losses, allowing smaller heatsink sizes.
**One Sentence Summary:** The STL57N65M5-VB is not an ordinary power MOSFET; it is the "efficiency engine" and "reliability cornerstone" for your high-voltage power supply designs.
