DDTA113ZCA-TP

Overview

The DDTA113ZCA-TP is a single PNP digital transistor manufactured by Micro Commercial Components (MCC). It integrates an epitaxial planar silicon NPN transistor with built-in biasing resistors in a compact SOT-23-3L surface-mount package. The device features a typical base resistor of 1 kOhm and an emitter-base resistor of 10 kOhms, yielding a resistance ratio of 10. Key electrical specifications include a maximum collector current of -100 mA, a power dissipation of 200 mW, and a transition frequency of 250 MHz. The saturation voltage is specified at -300 mV under standard test conditions, with a minimum DC current gain of 33 at 5 mA.

Feature Summary

• Integrates a single PNP transistor with dual internal biasing resistors to reduce external component count.
• Utilizes an epitaxial planar die construction for reliable performance within a small footprint.
• Designed for surface-mount assembly using the standard SOT-23-3L package configuration.

Applications

• General-purpose switching circuits requiring simplified bias networks.
• Driver stages for logic interfaces and relay control applications.
• Low-power signal processing and amplification tasks.

Procurement Notes

Verify the specific suffix 'ZCA' against the manufacturer's datasheet to confirm the exact resistor values and polarity, as variations exist within the DDTA family. Ensure the ordering code matches the required SOT-23-3L package type. Confirm RoHS compliance status through official documentation prior to procurement.

Selection Notes

Select this component when a PNP digital transistor with a 1k/10k resistor network is required. Compare the 250 MHz transition frequency and -100 mA current rating against circuit demands. Verify that the SOT-23-3L thermal dissipation capabilities meet the application's power requirements.

Part Context

This part belongs to the DDTA series of pre-biased transistors from Micro Commercial Components. It serves as a complementary or alternative solution to other digital transistors, offering integrated biasing to simplify PCB layout. The ZCA suffix typically denotes specific resistor ratios and packaging details within the MCC product line.

Replacement Considerations

Cross-reference with DTC113ZCA-TP for NPN equivalents or DTA113ZUA-TP for similar PNP configurations. Verify pinout compatibility and electrical parameters such as Vceo and hFE before substitution.
