Ultra‑Miniature SOT‑563 Package for High‑Density Switching and Level Shifting

MCC launches the BSS138KV, a compact 60V dual N‑channel MOSFET designed for modern electronics that demand more functionality in less space without compromising efficiency or reliability. This device integrates two independent 60V N‑channel MOSFETs with ESD protection into an ultra‑miniature SOT‑563 package.The space‑saving design significantly reduces component count and PCB footprint, making it ideal for portable, battery‑powered, and high‑density applications. 

Built on advanced trench LV MOSFET technology, the BSS138KV‑TP delivers low Rds(on) and low threshold voltage, minimizing conduction and switching losses for improved system efficiency even at low gate drive levels. Its dual configuration simplifies load switching, level shifting, and signal routing, enabling designers to optimize circuit architecture across multiple voltage domains. 

With integrated ESD‑protected gates and robust process technology, the device ensures long‑term reliability in harsh or noise‑prone environments. From consumer electronics and IoT devices to industrial automation and wearables, the BSS138KV‑TP offers a compact, efficient, and flexible solution for today’s space‑constrained designs.
