DTC124XM-TP

Overview

The DTC124XM-TP is an NPN pre-biased digital transistor manufactured by Micro Commercial Components. It integrates a single base resistor (R1) of 22 kOhms within a compact SOT-723 surface-mount package. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Key electrical characteristics include a transition frequency of 200 MHz, a DC current gain (hFE) minimum of 68 at 5 mA and 5 V, and a maximum power dissipation of 100 mW. The saturation voltage is specified at 300 mV under standard test conditions.

Feature Summary

• Integrates a single 22 kOhm base resistor for simplified circuit design
• Provides high-speed switching capability with a 200 MHz transition frequency
• Delivers reliable performance in a compact SOT-723 surface-mount footprint

Applications

• General-purpose switching applications
• Driver circuits for logic interfaces
• Signal level shifting between different voltage domains

Procurement Notes

Verify the specific datasheet revision when sourcing, as manufacturing parameters may evolve. Confirm that the SOT-723 package dimensions align with your PCB layout constraints. Ensure compatibility with your assembly process regarding moisture sensitivity levels. Cross-reference the manufacturer part number to avoid confusion with similar series components from other vendors.

Selection Notes

Select this component when a single-resistor NPN configuration is required for space-constrained designs. The 22 kOhm base resistance offers a balanced trade-off between drive current requirements and input impedance. Consider the 100 mA current rating to ensure adequate headroom for load requirements without exceeding thermal limits in the small package.

Part Context

This component belongs to the DTC124 series of pre-biased transistors from Micro Commercial Components. The series provides integrated biasing solutions to reduce external component count. The XM suffix denotes the specific SOT-723 package variant, distinguishing it from other package options like SOT-23 or SOT-523 available within the same functional family.

Replacement Considerations

Direct substitutes include the DTC124XE-TP (SOT-523 package) and DTC124XCA-TP (SOT-23 package), which share identical electrical specifications but differ in physical footprint. Verify pinout compatibility and thermal performance when substituting across different package types.
