STS17NF3LL is a STMicroelectronics N-Channel 30V-0.0045Ω-17A SO-8 STripFET™ II MOSFET for DC-DC conversion. The typical RDS(on) is 0.0045Ω @ 10V, and the best trade-off between RDS(on) and Qg is at 4.5V.
The STS17NF3LL is an N‑channel power MOSFET designed for high‑efficiency DC‑DC converters in telecom and computer applications. It uses STMicroelectronics' "Single Feature Size™" strip‑based process, offering a good trade‑off between on‑resistance and gate charge.
Key specifications include a 30 V drain‑source rating, 17 A continuous drain current at 25 °C, 68 A pulsed current, typical on‑resistance of 0.0045 Ω, and a total gate charge of 26 nC. Thermal data show a maximum junction‑to‑ambient resistance of 47 °C/W and an operating temperature range of –55 °C to 175 °C. The device is supplied in an SO‑8 package.
