DTC124ECAHE3-TP

Overview

The DTC124ECAHE3-TP is a single NPN digital transistor manufactured by Micro Commercial Components (MCC). It integrates an NPN bipolar junction transistor with internal biasing resistors in a surface-mount SOT-23 package. The device features a collector-emitter breakdown voltage of 50 V and a continuous collector current rating of 30 mA, with a peak DC collector current capability of 100 mA. Internal resistor values include a base resistor (R1) of 22 kOhms and an emitter resistor (R2) of 22 kOhms. Key electrical parameters include a minimum DC current gain (hFE) of 56 at 5 mA and 5 V, a transition frequency of 250 MHz, and a maximum power dissipation of 200 mW. The component operates within a temperature range of -55°C to +150°C and holds AEC-Q101 automotive qualification.

Feature Summary

• Integrates NPN BJT with dual internal biasing resistors for simplified circuit design
• Automotive-grade reliability certified under the AEC-Q101 standard
• High-frequency performance suitable for switching applications up to 250 MHz
• Compact SOT-23 surface-mount packaging for space-constrained layouts

Applications

• General-purpose switching circuits in automotive electronics
• Driver stages for low-power loads requiring pre-biasing
• Logic level translation and interface buffering
• Battery management system control logic

Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to ensure correct packaging configuration. Confirm that the AEC-Q101 qualification status aligns with the intended application requirements. Cross-reference the datasheet revision history to validate compliance with current environmental standards such as RoHS and REACH before finalizing procurement specifications.

Selection Notes

Select this component when a single NPN digital transistor with equal base and emitter resistance ratios is required. Ensure the operating voltage does not exceed the 50 V collector-emitter limit. Verify that the load current remains within the 30 mA continuous or 100 mA peak ratings. Consider the SOT-23 thermal characteristics for power dissipation limits in the target enclosure environment.

Part Context

This part belongs to the DTC124 series of pre-biased transistors from MCC. It shares the same internal resistor network topology as other variants but is distinguished by its specific NPN polarity and SOT-23 package form factor. The HE3 suffix typically indicates lead-free and halogen-free construction compliant with international environmental directives.

Replacement Considerations

Direct functional substitutes may include other NPN digital transistors with identical 22k/22k resistor ratios and 50V ratings, such as the DTC124EUA-TP in a different package or equivalent parts from other manufacturers like ROHM or onsemi, provided pinout compatibility and electrical limits are verified.
