20 V, 285 mA, N−Channel with ESD
Protection, SOT−723
Features
LNTK3043NT5G
•
•
•
•
•
Enables High Density PCB Manufacturing
44% Smaller Footprint than SC−89 and 38% Thinner than SC−89
Low Voltage Drive Makes this Device Ideal for Portable Equipment
Low Threshold Levels, V
GS(TH)
< 1.3 V
Low Profile (< 0.5 mm) Allows It to Fit Easily into Extremely Thin
Environments such as Portable Electronics
•
Operated at Standard Logic Level Gate Drive, Facilitating Future
Migration to Lower Levels Using the Same Basic Topology
•
These are Pb−Free Devices
