Silicon transistor dual npn pnp LRC LMBT3946DW1T1G with low VCE sat and compact SC88 SOT 363 package
Product Overview
The LMBT3946DW1T1G and S-LMBT3946DW1T1G are dual general-purpose silicon transistors, available in both NPN and PNP configurations. The 'S-' prefix denotes suitability for automotive and other applications with stringent site and control change requirements, offering AEC-Q101 qualification and PPAP capability. These transistors are designed to simplify circuit design, reduce board space, and decrease component count with their low VCE(sat) of 0.4 V.
