80 V NexFET™ — low-loss switch for 48 V rails and high-current POL
The Texas Instruments CSD19502Q5B is an 80 V, 100 A N-channel NexFET™ power MOSFET in a VSON-CLIP (5x6) package. It targets high-efficiency DC-DC converters, synchronous rectification stages, and motor-drive half-bridges where conduction loss matters. The 4.1 mΩ typical on-resistance at 10 V gate drive keeps dissipation low at 19 A load current, and the 62 nC gate charge at 10 V lets a standard gate driver switch it fast without excessive drive losses.
Temperature range and package — field fit
Rated for junction temperatures from -55 °C to 150 °C, this part covers industrial and automotive under-hood environments (though it is not AEC-Q101 listed here). The VSON-CLIP (5x6) package uses a large bottom-side pad that must be soldered to a thermal land on the PCB — the datasheet layout recommendation for the copper area is the reference for your board stack-up. Surface-mount reflow is standard; the CLIP construction reduces package resistance and improves current spreading into the die.
Lifecycle and sourcing
The CSD19502Q5B carries an Active product status with ROHS3 compliance. It remains a current-production part suitable for new designs.
