DDTC113ZCA-TP

Overview

The DDTC113ZCA-TP is an NPN digital transistor manufactured by Micro Commercial Components (MCC) in a SOT-23 package. It features built-in biasing resistors with R1 at 1 kΩ and a resistance ratio of 10. Key electrical specifications include a maximum collector current of 500 mA, power dissipation of 250 mW, and a transition frequency of 250 MHz. The device supports a supply voltage up to 50 V and operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Epitaxial planar die construction for reliable performance
• Integrated biasing resistors simplify circuit design
• Halogen-free 'Green' device compliant with environmental standards
• Moisture sensitivity level 1 for robust handling

Applications

• General-purpose switching applications
• Driver circuits for relays and solenoids
• Logic level translation interfaces

Procurement Notes

Verify the authenticity of the DDTC113ZCA-TP component by purchasing exclusively from Micro Commercial Components or their authorized distributors. Counterfeit parts pose significant risks; unauthorized sources do not provide warranty coverage. Ensure the ordering suffix matches the required packaging configuration before finalizing procurement orders.

Selection Notes

Select this component when a high-current NPN digital transistor is required, specifically noting its 500 mA collector current capability which exceeds standard 100 mA variants. Confirm that the SOT-23 footprint aligns with the PCB layout constraints. Verify that the internal resistor values meet the specific drive requirements of the target logic interface.

Part Context

This part belongs to the DTC113 series of pre-biased transistors from MCC. While similar to the DTC113ZCA-TP, the DDTC113ZCA variant offers higher current ratings. It serves as a compact solution for replacing discrete resistor-transistor networks in space-constrained designs requiring efficient signal buffering.

Replacement Considerations

Direct substitutes include the DTC113ZCA-TP for lower current needs. Cross-reference pinouts carefully when replacing with other manufacturers' SOT-23 digital transistors to ensure compatibility with the IN, GND, and OUT terminal assignments.
