概述
Description
PDTC114ET-QR is a digital transistor: an NPN transistor with an integrated base resistor, packaged in RoHS-compliant SOT-23 with tape-and-reel labeling (-QR). It lets a microcontroller drive a load (LEDs, small relays, etc.) directly from logic without needing an external base resistor. The internal base resistor limits base current, so the input pin can be driven from typical 3–5 V logic while the transistor switches the load in a common-emitter configuration. It is useful for simple interfacing, reducing parts count and simplifying protection in low-power switching applications. Exact electrical specs (I_C, V_CE, base-resistor value, switching speed) vary by variant; consult the PDTC114ET-QR datasheet for precise numbers, pinout, and packaging details.
