STMicroelectronics Reveals New Family of 100V Trench Schottky Rectifier Diodes for Increased Efficiency and Power Density
STMicroelectronics has introduced 100V trench Schottky rectifier diodes that boost efficiency in power converters operated at high switching frequencies.
意法半導體推出了 100V 溝槽肖特基整流二極管 這提高了在高開關頻率下運行的功率轉換器的效率。
Raising power-converter operating frequency, encouraged by the minimal switching losses of technologies like wide-bandgap semiconductors, allows designers to set new benchmarks in power density. However, at elevated frequencies, the energy losses in conventional planar diodes, including silicon Schottky devices, used as rectifiers become a significant factor limiting conversion efficiency.
在寬帶隙半導體等技術的最小開關損耗的鼓勵下，提高功率轉換器的工作頻率使設計人員能夠在功率密度方面設定新的基準。但是，在較高的頻率下，包括用作整流器的硅肖特基器件在內的傳統平面二極管的能量損失成爲限制轉換效率的重要因素。
ST's trench Schottky diodes significantly reduce the rectifier losses, with superior forward-voltage and reverse-recovery characteristics that enable increased power density with high efficiency. The forward voltage is 50-100mV better than in comparable planar diodes, depending on current and temperature conditions. Simply changing to these devices can increase the efficiency by 0.5%.
意法半導體的溝槽肖特基二極管 顯著降低整流器損耗，具有卓越的正向電壓和反向恢復特性，可提高功率密度，提高效率。正向電壓比同類平面二極管好 50-100mV，具體取決於電流和溫度條件。只需更換這些設備即可將效率提高0.5％。
There are 28 variants in the new family, with eight current ratings from 1A to 15A, multiple surface-mount packages, in industrial and automotive grades. The industrial-grade parts target applications such as miniature switched-mode power supplies and auxiliary power supplies for telecom, server, and smart-metering equipment. In automotive, typical uses include space-constrained applications such as LED lighting, reverse-polarity protection, and low-voltage DC/DC converters. The parts are AEC-Q101 qualified, manufactured in PPAP-capable facilities, and specified from -40°C to 175°C.
有 新家族有 28 個變體，具有從 1A 到 15A 的八個額定電流，工業和汽車等級的多種表面貼裝封裝。工業級部件的目標應用包括微型開關模式電源和電信、服務器和智能計量設備的輔助電源。在汽車領域，典型用途包括空間受限的應用，例如 LED 照明、反極性保護和低電壓 DC/DC 轉換器。這些部件符合 AEC-Q101 標準，在支持 PPAP 的設施中製造，規定溫度範圍爲 -40°C 至 175°C。
When combined with ST's flyback and buck-boost converters, such as the VIPer controllers and HVLED001A offline LED driver, the 100V trench Schottky rectifiers fulfil the active-components bill of materials for switched-mode power supplies. All are supported in ST's eDesign Suite Rectifier Diodes Simulator, which helps to select the rating and footprint, simulate waveforms, and estimate power efficiency.

The diodes are 100% avalanche tested in production to ensure device robustness and system reliability. They are available in DPAK as well as SOD123 Flat, SOD128 Flat, SMB Flat, and PSMC (TO227A) surface-mount packages.

All devices are in production now. Budgetary pricing starts at $0.107 for the 1A STPST1H100ZF in SMD123 Flat.
所有設備現已投入生產。SMD123 Flat 中的 1A STPST1H100ZF 的預算起價爲0.107美元。
