SOT-23-3L Digital Transistors | Built-in Bias Resistor

SOT-23-3L Series

SOT-23-3L Digital Transistors with Built-in Resistors for Signal Switching and Logic Driving

Product Description
Product Parameters

The SOT-23-3L digital transistor series integrates internal bias resistors to minimize external component count. Available in both PNP and NPN versions, these transistors offer configurations from standard (R2/R1 = 1) to high-ratio types (R2/R1= 21), making them suitable for logic interfacing, signal switching, and microcontroller port driving applications.

Microcontroller signal interface
Logic level translation
LED driving switches
Battery signal control
Auto reset and logic control
