DTA124ECAHE3-TP

Overview

The DTA124ECAHE3-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 are typically 22 kOhms for both the base (R1) and emitter (R2) positions, resulting in a typical resistance ratio of 1. 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

• Integrated pre-bias network simplifies circuit design by reducing external component count
• Automotive-grade reliability certified under AEC-Q101 standards
• High-speed switching performance supported by 250 MHz transition frequency

Applications

• Switching applications in automotive electronic control units
• Driver circuits for low-power loads in vehicle systems
• Logic level translation and buffer stages in embedded controllers

Procurement Notes

Verify authenticity through authorized MCC distributors or verified supply chain channels. Confirm AEC-Q101 certification status and RoHS compliance via official datasheets. Check for recent Product Change Notifications (PCNs) regarding packaging or manufacturing site updates. Ensure storage conditions adhere to moisture sensitivity level requirements prior to soldering.

Selection Notes

Select this component when a single NPN digital transistor with 22 kOhm biasing resistors is required in an SOT-23 package. Verify that the 30 mA continuous collector current meets load requirements. Consider the 50 V voltage rating for system compatibility. Compare against other DTC/DTA series variants if different resistor ratios or PNP polarity are needed.

Part Context

This part belongs to the DTC124ECA/DTA124ECA family of pre-biased transistors from Micro Commercial Components. The 'H' suffix typically indicates halogen-free construction, while 'E3' denotes lead-free termination. The 'TP' suffix signifies tape and reel packaging. This specific model represents the PNP counterpart configuration in naming conventions but is documented here as an NPN device per provided specifications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-referencing should be performed using identical electrical parameters: NPN polarity, 50V VCEO, 22kΩ/22kΩ resistors, and SOT-23 package.
