Overview
The DTA124ECA-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates bias resistors within a single SOT-23 package to simplify circuit design. Key electrical specifications include a maximum collector-emitter voltage of -50V and a continuous collector current of -100mA. The device features an internal base resistor (R1) of 22kΩ and an emitter-base resistor (R2) of 22kΩ, resulting in a resistance ratio of 1.0. It operates with a transition frequency of 250MHz and a DC current gain of 56. Power dissipation is rated at 200mW, with a storage temperature range from -55°C to 150°C.
Feature Summary
- Built-in thin-film bias resistors enable inverter circuit configuration without external input resistors.
- Resistors provide complete isolation to allow negative biasing of the input and eliminate parasitic effects.
- Halogen-free "Green" device compliant with RoHS standards.
Applications
- Inverter circuits
- Driver circuits for relays and solenoids
- Switching applications
Procurement Notes
Verify authenticity through authorized MCC distributors or direct purchase to avoid counterfeit components. Confirm the specific ordering suffix matches the required packaging format. Ensure compliance with project-specific environmental regulations regarding halogen content and lead-free finish requirements before finalizing procurement decisions.
Selection Notes
Select this component when a compact PNP switching solution with integrated biasing is required. The SOT-23 package suits space-constrained surface-mount designs. Verify that the -50V voltage rating and -100mA current capacity align with the target load requirements. Consider the 22kΩ internal resistance values for appropriate base drive calculations.
