STMicroelectronics Launches 100V Trench Schottky Rectifier Diodes Tailored for Power Conversion Applications
STMicroelectronics Unveils High-Efficiency 100V Trench Schottky Rectifier Diodes for Power Converters
STMicroelectronics, a leading innovator in semiconductor solutions, has introduced a new generation of 100V trench Schottky rectifier diodes designed to significantly improve efficiency in power converters operating at high switching frequencies.
Unlocking New Levels of Power Density
The trend towards higher switching frequencies in power converters is driven by technologies like wide-bandgap semiconductors, which offer minimal switching losses. This allows engineers to achieve groundbreaking power density in their designs. However, conventional planar diodes, including silicon Schottky devices, used as rectifiers exhibit increased energy losses at high frequencies, hindering overall conversion efficiency.
ST's Trench Schottky Diodes: Efficiency Redefined
STMicroelectronics' new trench Schottky diodes address this challenge head-on, providing superior forward voltage and reverse-recovery characteristics. These advancements translate to significantly reduced rectifier losses and enable designers to achieve higher power density while maintaining excellent efficiency. Compared to conventional planar diodes, ST's trench Schottky diodes offer a remarkable 50-100mV improvement in forward voltage depending on current and temperature conditions. In some cases, simply switching to these new diodes can yield a notable efficiency gain of 0.5%.
Diverse Options for Flexible Design Integration
The new family of trench Schottky diodes encompasses 28 variants, catering to a wide range of design requirements. This comprehensive offering features:
- Eight Current Ratings: Providing flexibility for various applications, with options ranging from 1A to 15A.
- Multiple Surface-Mount Packages: Including DPAK, SOD123 Flat, SOD128 Flat, SMB Flat, and PSMC (TO227A) packages, ensuring compatibility with diverse PCB layouts.
- Industrial and Automotive Grades: Offering solutions for a broad spectrum of applications, from industrial to automotive environments.
Ideal Applications Across Industries
The industrial-grade variants are perfectly suited for applications such as:
- Miniature switched-mode power supplies
- Auxiliary power supplies in telecom equipment
- Server power supplies
- Smart metering equipment
Automotive-grade devices are ideal for space-constrained applications, including:
- LED lighting systems
- Reverse-polarity protection circuits
- Low-voltage DC/DC converters
These automotive-grade diodes are AEC-Q101 qualified, manufactured in facilities certified for Production Part Approval Process (PPAP), and boast a wide operating temperature range of -40°C to 175°C.
A Complete Solution for Switched-Mode Power Supplies
When combined with ST's comprehensive portfolio of flyback and buck-boost converters, such as the VIPer controllers and HVLED001A offline LED driver, the 100V trench Schottky rectifiers provide a complete bill of materials (BOM) solution for high-efficiency switched-mode power supplies.
Design Support and Robust Manufacturing
ST's commitment to design support extends to their eDesign Suite Rectifier Diodes Simulator. This user-friendly tool empowers engineers to effortlessly:
- Select the most appropriate diode for their specific requirements based on current rating and footprint.
- Simulate waveforms to predict circuit behavior.
- Estimate power efficiency for informed design decisions.
For additional peace of mind, all ST's trench Schottky diodes undergo a rigorous 100% avalanche test during production, guaranteeing exceptional device robustness and system reliability.
