ORDERING INFORMATION
LMBT3904DW1T1 SOT–3633000 Units/Reel
The LMBT3904DW1T1 device is a spin–off of our popular
SOT–23/SOT–323 three–leaded device. It is designed for general
purpose amplifier applications and is housed in the SOT–363
six–leaded surface mount package. By putting two discrete devices in
one package, this device is ideal for low–power surface mount
applications where board space is at a premium.
•hFE, 100–300
•Low VCE(sat), ≤ 0.4 V
•Simplifies Circuit Design
•Reduces Board Space
•Reduces Component Count
•Available in 8 mm, 7–inch/3,000 Unit Tape and Reel
•Device Marking:LMBT3904DW1T1 = MA
