UMF9N is a dual transistor power management chip launched by ROHM, with a UMT6 package that is compatible with the EIAJ SC-88 standard. The chip is manufactured using Si single crystal planar technology, with wide input and output voltage range and low power consumption. It is suitable for various power management circuits.
The UMF9N dual transistor integrates the 2SC5585 and 2SK3019 devices in a single UMT6 package, offering a power‑switching solution that reduces mounting cost and board area. The datasheet provides detailed absolute maximum ratings, electrical characteristics, and typical performance curves for design reference.
Key sections include packaging specifications, absolute maximum ratings, electrical parameters such as collector‑base voltage, collector‑emitter voltage, hFE, and on‑state resistance, as well as characteristic curves for current gain, saturation voltage, and switching behavior.
