Overview
The DDTA123YCA-TP is a PNP digital transistor manufactured by Micro Commercial Components (MCC). It features an epitaxial planar die construction and includes built-in biasing resistors to simplify circuit design. The device operates with a supply voltage of -50 V, a maximum output current of -500 mA, and a power dissipation of 200 mW. Key electrical parameters include a typical input resistance (R1) of 2.2 kΩ, a transition frequency of 200 MHz, and a DC current gain of 56. It is housed in a SOT-23 package.
Feature Summary
- Integrates internal biasing resistors to eliminate the need for external components in inverter circuits.
- Utilizes epitaxial planar die construction for reliable performance.
- Complies with RoHS standards and meets UL 94 V-0 flammability ratings.
Applications
- Inverter circuits
- Switching applications
- Driver circuits
Procurement Notes
Verify authenticity by purchasing directly from MCC or authorized distributors to avoid counterfeit parts. Confirm that the ordering suffix indicates RoHS compliance. Ensure the component meets specific environmental requirements such as moisture sensitivity level 1 before integration into the final assembly process.
Selection Notes
Select this component for PNP switching applications requiring integrated biasing. Verify that the -50 V supply voltage and -500 mA output current meet system demands. Consider the SOT-23 package dimensions and thermal derating characteristics when designing the PCB layout and heat dissipation strategy.
Part Context
This part belongs to the DDTA123YCA series of pre-biased transistors. It is designed as a replacement for discrete resistor-transistor networks, reducing board space and assembly time. The 'TP' suffix denotes tape and reel packaging containing 3000 pieces per reel.
Replacement Considerations
Direct substitutes may include other PNP digital transistors with similar R1 values and SOT-23 packaging. Verify pinout compatibility and electrical limits before substitution.
