Overview
The DDTC123ECA-TP is a pre-biased NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates an NPN bipolar junction transistor with internal bias resistors in a compact SOT-23 surface-mount package. Key electrical specifications include a collector-emitter breakdown voltage of 50 V, a continuous collector current of 100 mA, and a maximum power dissipation of 200 mW. The device features typical base resistor (R1) and emitter resistor (R2) values of 2.2 kOhms each. It operates within a temperature range of -55°C to +150°C and complies with RoHS standards.
Feature Summary
- Integrates NPN transistor with dual bias resistors for simplified circuit design
- Compact SOT-23 surface-mount packaging for space-constrained applications
- Wide operating temperature range suitable for industrial environments
Applications
- Switching circuits in consumer electronics
- Driver stages for logic interfaces
- General-purpose digital switching applications
Procurement Notes
Verify the specific suffix ECA against the manufacturer's latest datasheet to confirm pinout and electrical tolerances. Confirm RoHS compliance status directly with the supplier or through official documentation before integration. Ensure the ordering quantity matches available reel or cut-tape configurations provided by authorized distributors.
Selection Notes
Select this component when an NPN configuration with integrated biasing is required. Compare the 2.2 kOhm internal resistance values against circuit requirements to ensure proper drive levels. Verify that the 50 V breakdown voltage and 100 mA current rating exceed the application's peak operational demands.
Part Context
This part belongs to the DDTC series of pre-biased transistors from MCC. It serves as a discrete solution replacing multiple external components. The ECA suffix typically denotes specific packaging or variant details within the manufacturer's catalog structure.
Replacement Considerations
Cross-reference with DTC123ECA-TP for PNP equivalents or other manufacturers' NPN pre-biased transistors with identical 2.2k/2.2k resistor ratios and SOT-23 footprints.
