Schottky barrier ensrettere udfordrer konventionelle switching-dioder
Littelfuse annoncerer Schottky barrier ensrettere med ultralavt forward spændingsdrop, hvilket gør dem ideelle til brug i bl.a. højfrekvens switch-mode strømforsyninger og DC/DC konvertere.
Littelfuse, Inc., a global leader in circuit protection, has added a series of silicon Schottky devices designed for ultra-low forward voltage drop (VF) to its rapidly expanding power semiconductor portfolio.The new DST Series is well-suited for use in high-frequency applications such as switch-mode power supplies, as well as DC application such as solar panel bypass diode and polarity protection diodes, the DST Series Schottky Barrier Rectifier is designed to meet the requirements of commercial and industrial applications.
By delivering performance superior to conventional switching diodes, they offer high junction temperature capability, low leakage and ultra-low forward voltage drop. Their higher junction temperature capability and low leakage provide higher reliability in harsh, high-temperature environments.
- The DST Series’ ultra-low forward voltage drop performance is an important new addition to the growing Littelfuse power semiconductor device offering. I’m confident it will help us add depth to our power semiconductor portfolio and expand our applications and market coverage, says Corey Deyalsingh, director of power control semiconductors at Littelfuse.
DST Series Schottky Barrier Rectifiers offer these key benefits:
• Their ultra-low forward voltage drop (VF) reduces thermal and electrical conduction losses, thereby improving system efficiency.
• Because they provide fast switching, they can be used in very high frequency applications with minimal switching loss.
• Their high junction temperature capability ensures high reliability in high ambient temperatures or in applications with minimal cooling available.
DST Series Schottky Barrier Rectifiers are available in a variety of package types and sizes, including TO-263 (D2PAK), ITO-252 (DPAK), ITO-220AB, TO-220AB, TO-220AC, P600, PDFN5x6-8L, and TO 277B.
