概要

Description

DDTC114ECA-7-F is a digital transistor (NPN) with built-in base bias resistors. It belongs to the DTC family and is designed to be driven directly from a microcontroller or logic IC without needing an external base resistor.
Key points:
- Configuration: 3-pin device (emitter, base with internal resistor, collector).
- Function: acts as a small-signal switch; loads are driven via the collector side, with the base current limited by the internal resistor.
- Benefits: simplifies designs, reduces component count, and provides a clean MCU interface (logic-level input, safer base current).
- Packaging: typically SOT-23 or similar; the -F suffix usually indicates Pb-free, tape-and-reel packaging (variant details may vary by supplier).
- Applications: LED driving, small relays or motors, optocoupler interfacing, and other low-current switching tasks.
Notes:
- Exact base current, maximum collector current, and voltage ratings vary by variant. Check the manufacturer’s datasheet for Rin, Ic max, Vce, switching speed, and recommended operating conditions.

Features

Here are the typical features of DDTC114ECA-7-F (Dual Digital Transistor with built-in resistors):
- Dual NPN digital transistors with built-in base resistors
- Two independent channels
- No external base resistor required; drives directly from logic signals (TTL/CMOS compatible)
- Each channel can sink up to about 50 mA (per-device rating; check datasheet for exact per-channel Ic)
- Vceo (max) up to about 60 V (range depends on variant)
- Low input current and fast switching; high current gain
- Wide operating temperature range (approx. -40 to 125 C)
- Surface-mount package (lead-free, RoHS compliant)
- Package option suitable for reel/tape manufacturing
Note: exact electrical values (Ic per channel, Vceo, etc.) can vary by variant. Please consult the official datasheet for precise specifications for the -7-F revision.

Package

SC-74A 6-pin SOT-23 style package (6-pin).

Pinout

Pin count: 3 pins (SOT-23-3 package).
Function: NPN digital transistor with an integrated base resistor (DTC family). It provides limited base current from a logic input, suitable for directly driving a load as a low-side switch (emitter to ground, collector to the load, load to supply).

Manufacturer

- Manufacturer: ROHM Semiconductor (ROHM Co., Ltd.)
- Company type: A Japanese multinational electronics company that designs and manufactures semiconductors and electronic components (diodes, transistors, ICs, power devices, etc.) sold worldwide.

Application

DDTC114ECA-7-F is a digital transistor (NPN) with a built-in base resistor/current-limiting. Applications: direct drive from microcontrollers; LED indicators; driving small relays/solenoids; input stages for optocouplers; and general-purpose switching in consumer, automotive, and industrial electronics.
