DTC123EUA-TP

Overview

The DTC123EUA-TP is a single NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates pre-biased resistors within 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 typical base resistor (R1) and emitter resistor (R2) value of 2.2 kOhms each. DC current gain (hFE) is specified at a minimum of 20 under test conditions of 20 mA collector current and 5 V collector-emitter voltage. Saturation voltage is limited to 300 mV at 500 µA base current and 10 mA collector current. Power dissipation is rated at 200 mW, with an operating temperature range from -55°C to +150°C.

Feature Summary

• Integrates dual biasing resistors to simplify circuit design and reduce component count.
• Optimized for high-speed switching applications with a 250 MHz transition frequency.
• Designed for compact surface-mount assembly in space-constrained environments.

Applications

• General-purpose switching circuits requiring minimal external components.
• Driver stages for logic interfaces and signal level translation.
• Power management control circuits in portable electronic devices.

Procurement Notes

Verify the specific suffix 'TP' against the manufacturer's datasheet to confirm compliance with RoHS3 directives and halogen-free status. Confirm that the SOT-323 package dimensions match the target PCB footprint requirements. Ensure that the 200 mW power dissipation rating aligns with the thermal constraints of the intended application environment.

Selection Notes

Select this component when a single NPN digital transistor with 2.2 kOhm biasing resistors is required. Compare the 50 V breakdown voltage and 100 mA current limits against circuit demands. Consider the 250 MHz frequency response for high-speed switching needs. Verify compatibility with standard SMT reflow processes given the small outline package.

Part Context

This part belongs to the DTC123 series of pre-biased transistors from MCC. It shares the same internal resistor configuration as other variants but differs in packaging or qualification standards. The SOT-323 form factor distinguishes it from larger packages like SOT-23 while offering similar electrical characteristics for compact designs.

Replacement Considerations

Cross-reference with other manufacturers offering NPN digital transistors in SOT-323 packages with identical 2.2 kOhm resistor values. Verify pinout compatibility and ensure equivalent voltage and current ratings are met before substitution.
