DTC123JCAHE3-TP

Overview

The DTC123JCAHE3-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 compact SOT-323-3 surface-mount package. The device features a typical base resistor of 2.2 kOhms and an emitter resistor of 47 kOhms, resulting in a standard resistor ratio of 21. It supports a continuous collector current of 100 mA and offers a minimum DC current gain (hFE) of 80 at 10 mA and 5 V. The component is rated for a maximum power dissipation of 200 mW and operates within a temperature range up to +150°C.

Feature Summary

• Integrates NPN transistor with pre-biased resistors for simplified circuit design
• Utilizes SOT-323-3 surface-mount packaging for space-efficient board layout
• Provides high current gain capability suitable for switching applications

Applications

• General-purpose switching circuits
• Driver stages for logic interfaces
• Battery-powered portable devices requiring low component count

Procurement Notes

Verify the complete part number including the HE3 suffix to ensure compliance with specific environmental standards such as halogen-free requirements. Confirm that the SOT-323-3 footprint matches the target PCB design. Check official manufacturer documentation for any recent product change notices regarding assembly or material composition updates before finalizing procurement plans.

Selection Notes

Select this component when a single NPN digital transistor with a 2.2 kOhm base resistor is required. Ensure the application voltage does not exceed the specified limits and that the thermal management accommodates the 200 mW power dissipation rating. Compare against other variants in the DTC123 series if different resistance ratios or package types are needed for the specific design constraints.

Part Context

This part belongs to the DTC123JCA series of digital transistors from Micro Commercial Components. It is distinct from PNP counterparts like the DTA123JCA and other NPN variants with different resistor values. The HE3 designation indicates specific manufacturing attributes related to environmental compliance, distinguishing it from standard commercial grade parts without this suffix.

Replacement Considerations

Direct substitutes include other MCC parts within the same series with identical electrical characteristics but potentially different packaging or suffixes. Cross-manufacturer equivalents must match the NPN configuration, 100 mA current rating, and SOT-323-3 package dimensions.
