Frequently Asked Questions
What is the RDS(on) and maximum drain current of CSD19535KTT?
The CSD19535KTT has a typical RDS(on) of 4.1mΩ at VGS=10V and a maximum continuous drain current (ID) of 35A at 25°C. This ultra-low on-resistance minimizes conduction losses, making it highly efficient for high-current power conversion stages.
What package does the CSD19535KTT come in and what are its dimensions?
The CSD19535KTT uses TI's SON 5x6mm (KTT) package with 8 pins. This compact, thermally enhanced package provides excellent heat dissipation with a low thermal resistance, enabling high power density designs in space-constrained applications.
What are typical applications for the CSD19535KTT MOSFET?
CSD19535KTT is designed for synchronous rectification, DC-DC converters (buck, boost, and half-bridge topologies), industrial motor drives, server power supplies, and 12V automotive power systems. Its combination of low RDS(on) and fast switching characteristics suits it for high-efficiency, high-frequency power stages.
Is the CSD19535KTT RoHS compliant and automotive qualified?
Yes, the CSD19535KTT is fully RoHS compliant and lead-free. Texas Instruments also offers AEC-Q101 qualification for this part, making it suitable for automotive-grade applications requiring high reliability under extended temperature and stress conditions.
What are good alternatives to the CSD19535KTT?
Compatible alternatives include the CSD19532Q5B (100V, 100A, QFN package, lower RDS(on)), the CSD19505KTT (80V, lower voltage variant in the same KTT package), and the Vishay SiR626ADP (100V N-Channel MOSFET in PowerPAK SO-8 package with similar RDS(on) characteristics).
