概述

Description

PDTC114ET-QR is a digital transistor: an NPN transistor with an integrated base resistor. This lets you drive the device directly from logic signals (TTL/CMOS) without needing an external base resistor. The -QR suffix denotes Tape & Reel packaging for automated assembly.
Typical use: act as a small switching driver for loads such as LEDs, relays, or optocouplers, sinking current from a load connected to a supply.
Key points:
- Built-in base resistor provides safe, fixed base current for logic inputs.
- It functions as a convenient, compact switch with simplified wiring.
- Packaging and exact internal resistor value depend on the exact variant; check the datasheet for V_CE, I_C, and pinout.
For precise electrical specs (maximum collector-emitter voltage, continuous collector current, input current, gain, and package type), consult the manufacturer’s datasheet for PDTC114ET-QR.

Features

PDTC114ET-QR is a digital NPN transistor with built-in base resistor. Key features:
- Built-in base resistor: no external base resistor required; logic-level drive from MCU.
- Logic compatibility: can be driven directly from 3.3/5 VLogic signals.
- I_C(max): typically around 50 mA; V_CE(max) up to about 40 V.
- Low saturation: V_CE(sat) ~0.2–0.3 V at moderate I_C.
- Fast switching suitable for general switching applications.
- Package: SOT-23-3 with Tape & Reel (QR) packaging; RoHS compliant.
- Applications: driving LEDs, small relays, and other low-power loads in microcontroller circuits.

Package

PDTC114ET-QR uses a SOT-23 (3-pin) package. The “-QR” suffix signifies Tape & Reel packaging.

Pinout

- Pin count: 3 pins
- Function: NPN digital transistor with a built-in base resistor. Pin 1 = Base (input, with internal resistor), Pin 2 = Collector, Pin 3 = Emitter. -QR indicates tape-and-reel packaging (SOT-23).

Manufacturer

- Manufacturer: Panasonic (Matsushita Electric Industrial Co., Ltd.), specifically Panasonic Semiconductor Solutions.
- What kind of company: A Japanese multinational electronics company that designs and manufactures consumer electronics and a wide range of electronic components, including semiconductors.
