Overview
The DTA123JCAHE3-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. Key electrical specifications include a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. The device features a typical base resistor value of 2.2 kOhms and a standard resistor ratio of 21. DC current gain (hFE) is specified at a minimum of 80 when tested at 10 mA and 5 V. Power dissipation capability is rated at 200 mW, with a saturation voltage of 300 mV. The component supports operating temperatures up to +150 C and is AEC-Q101 qualified for automotive applications.
Feature Summary
- Integrates NPN transistor with pre-biased resistors for simplified circuit design
- AEC-Q101 qualified for automotive reliability standards
- Compact SOT-323-3 surface-mount packaging for space-constrained applications
Applications
- Automotive electronic control units requiring qualified discrete components
- General-purpose switching circuits in consumer electronics
- Interface driving applications in industrial control systems
Procurement Notes
Verify the complete part number including the HE3 suffix to ensure correct lead-free and halogen-free compliance status. Confirm that the SOT-323-3 package variant matches the footprint requirements of the target PCB design. Check for specific automotive grade certifications if the application demands AEC-Q101 validation beyond standard commercial ratings.
Selection Notes
Select this component when a single NPN digital transistor with integrated biasing is required in a small outline package. Ensure the 50 V collector-emitter voltage rating exceeds the maximum circuit voltage. Verify that the 2.2 kOhm base resistor value aligns with the drive source impedance and desired switching speed characteristics for the specific application load.
Part Context
This part belongs to the DTC123/DTA123 series of pre-biased transistors from MCC. The HE3 designation indicates a specific environmental compliant version within the product line. It serves as the NPN counterpart to PNP variants like the DTA123JCAHE3-TP, offering similar electrical performance but with opposite polarity characteristics for complementary circuit designs.
Replacement Considerations
Direct substitutes may include other NPN digital transistors in SOT-323 packages with matching 50V/100mA ratings and similar base resistance values. Verify pinout compatibility and thermal characteristics before substitution.
