概述

Description

PDTC124ET-QR is a digital NPN transistor with a built-in base resistor, in a small SOT-23 package with Tape & Reel (QR) packaging. It lets you drive loads directly from a logic output without an external base resistor.
Key points:
- 3-pin device: base (input), emitter, collector (output to load).
- Built-in base resistor provides defined base current from the driving logic.
- Ideal for interfacing microcontrollers to LEDs, relays, optocouplers, and small loads.
- Benefits: fewer parts, consistent switching, simpler interface, better protection for the driving MCU.
- Packaging: SOT-23, -QR denotes tape-and-reel.
Usage notes:
- Connect input to MCU logic output; emitter to ground; load between Vcc and collector.
- Ensure the load current and voltage stay within the device’s Ic and Vce ratings (see datasheet for exact limits).
For exact electrical specs and pinout, consult the PDTC124ET-QR datasheet from the manufacturer.

Features

Concise features of PDTC124ET-QR:
- NPN digital transistor with built-in base resistor (no external base resistor needed)
- Direct-drive from logic/microcontroller inputs (TTL/CMOS compatible)
- Open-collector style output suitable for sinking loads
- Reduces component count and PCB footprint; simplified BOM
- Suitable for switching modest loads (LEDs, small transistors, relays)
- Fast switching for digital applications
- Pb-free / RoHS compliant
- Packaging: Tape & Reel (QR) for automated assembly and handling
Note: For exact electrical ratings (Vce, Ic, base resistance, switching speeds, etc.), please refer to the datasheet.

Package

PDTC124ET-QR uses a 3-pin SOT-23 surface-mount package. The -QR suffix indicates Tape & Reel (reel-packaged) packaging for automated handling.

Pinout

3 pins. It is an NPN digital transistor with a built-in base resistor. Pin 1 = Base (input, current-limited by internal resistor), Pin 2 = Emitter, Pin 3 = Collector (output). It sinks load current when the input is high and requires no external base resistor. The “-QR” suffix indicates tape & reel packaging.

Manufacturer

Manufacturer: Toshiba (Toshiba Electronic Devices & Storage Corporation).
What kind of company: A Japanese multinational electronics company that designs and manufactures semiconductors, storage devices, and other electronic components for various industries.

Application
