DTA123EUA-TP

Overview

The DTA123EUA-TP is a single PNP pre-biased digital transistor manufactured by Micro Commercial Components (MCC). It integrates a BJT with internal biasing resistors R1 and R2, both rated at 2.2 kOhms, housed in an SOT-323 surface-mount package. Key electrical specifications include a maximum collector-emitter voltage of 50 V, a continuous collector current of 100 mA, and a transition frequency of 250 MHz. The device features a maximum power dissipation of 200 mW, a minimum DC current gain (hFE) of 20 at 20 mA and 5 V, and a maximum saturation voltage of 300 mV at 500 µA base current and 10 mA collector current.

Feature Summary

• Integrates a PNP bipolar junction transistor with dual internal biasing resistors to simplify circuit design.
• Utilizes an SOT-323 surface-mount package for compact board space efficiency.
• Provides high-speed switching capabilities supported by a 250 MHz transition frequency.

Applications

• General-purpose switching applications requiring pre-biased logic interfaces.
• Driver circuits for low-current loads such as LEDs or relays.
• Level shifting between different logic voltage domains in portable electronics.

Procurement Notes

Verify the specific suffix 'EUA' against the manufacturer's latest datasheet to confirm pinout compatibility and resistor values. Ensure that the ordering information matches the required packaging format, such as cut tape or reel, as indicated on the distributor listing. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a PNP configuration with 2.2 kOhm biasing resistors is required for interface buffering. Compare the 50 V breakdown voltage and 100 mA current rating against load requirements. Consider the SOT-323 footprint constraints and thermal dissipation limits of 200 mW during initial circuit planning.

Part Context

This part belongs to the DTA series of pre-biased transistors from MCC, designed to replace discrete resistor-transistor networks. It serves as a direct functional equivalent to industry-standard parts like the ON Semiconductor DTA123EUA, offering similar electrical characteristics within the same SOT-323 form factor for cross-vendor flexibility.

Replacement Considerations

Publicly confirmed substitute part numbers are not explicitly listed in the provided source material. Engineers should verify compatibility with generic equivalents such as the DTA123EUA from other manufacturers based on matching pinouts and electrical parameters.
