PN4391/4392/4393/MMBF4391/4392/4393 are N-channel switch devices, used for low level analog switching, sample and hold circuits and chopper stabalized amplifiers.
The Fairchild PN4391, PN4392, PN4393 (and their MMBF variants) are N‑Channel switches intended for low‑level analog switching, sample‑and‑hold circuits, and chopper‑stabilized amplifiers. The datasheet provides absolute maximum ratings, thermal characteristics, and detailed electrical parameters such as drain‑gate voltage, gate‑source voltage, and on‑state resistance.
Packaging information includes TO‑92 and SOT‑23 tape‑and‑reel options, with dimensions, reel capacities, and labeling details for bulk shipping. The document also contains trademark notices and product status definitions.
