Overview
The DTA123ECA-TP is a PNP digital transistor from Micro Commercial Components, housed in an SOT-23 package. It integrates thin-film bias resistors (R1 and R2) with a ratio of 1:1, where each resistor has a typical value of 2.2 kΩ. The device supports a supply voltage of -50 V and a continuous collector current of -100 mA. Key electrical parameters include a DC current gain (hFE) of 30 at VCE=-10V and IC=-20mA, and a collector-emitter saturation voltage of -0.25 V max. Power dissipation is rated at 200 mW, with an operating temperature range of -55°C to +150°C.
Feature Summary
- Built-in bias resistors enable inverter circuit configuration without external input resistors
- Thin-film resistors provide complete isolation for negative biasing and minimize parasitic effects
- Simplified design by requiring only on/off condition settings for operation
Applications
- Inverter circuits
- Switching applications
- Logic interface circuits
Procurement Notes
Verify the authenticity of the DTA123ECA-TP component through authorized MCC distributors or direct procurement channels. Counterfeit prevention measures are critical; ensure traceability and compliance with MCC quality standards. Confirm RoHS compliance and packaging specifications (Tape & Reel, 3Kpcs/Reel) against official datasheets before integration into production lines.
Selection Notes
Select the DTA123ECA-TP for PNP switching applications requiring integrated biasing in an SOT-23 footprint. Ensure the required collector current does not exceed -100 mA and the supply voltage remains within -50 V. Verify that the 2.2 kΩ internal resistance aligns with the target logic levels and drive requirements. Consider the -55°C to +150°C operating range for environmental suitability.
Part Context
The DTA123ECA-TP belongs to the DTA123 series of PNP digital transistors manufactured by Micro Commercial Components. This series is designed to simplify circuit design by replacing discrete biasing components with integrated thin-film resistors. The 'TP' suffix indicates Tape & Reel packaging, while the 'E' in the model number typically denotes specific electrical characteristics or pinout variations within the family.
Replacement Considerations
When substituting this component, verify compatibility with PNP polarity, SOT-23-3 package dimensions, and similar electrical ratings (-50V, -100mA). Check if alternative parts offer comparable bias resistor values (approx. 2.2kΩ) and hFE characteristics. Ensure the replacement meets the same thermal and safety certifications.
