Overview
The DTA123JUAHE3-TP is a PNP digital transistor from Micro Commercial Components, housed in an SOT-323 package. It integrates a single NPN transistor with internal biasing resistors R1 and R2. Key electrical parameters include a maximum supply voltage (VCC) of -50 V, a continuous collector current (IC) of -100 mA, and a power dissipation (PD) of 200 mW. The typical input resistance (R1) is 2.2 kOhms, with a resistance ratio (R2/R1) of 21. The DC current gain (hFE) is specified at a minimum of 80. Transition frequency (fT) reaches 250 MHz under specific test conditions.
Feature Summary
- AEC-Q101 qualified for automotive reliability standards
- Halogen-free 'Green' device compliant with RoHS directives
- Moisture Sensitivity Level 1 rating for robust handling
- Epoxy material meets UL 94 V-0 flammability rating
Applications
- Automotive electronic circuits requiring AEC-Q101 compliance
- General-purpose switching applications utilizing pre-biased resistor networks
- Low-voltage logic interface circuits for signal level translation
Procurement Notes
Verify component authenticity by purchasing exclusively from authorized Micro Commercial Components distributors or directly from the manufacturer. Unverified sources may result in counterfeit parts lacking traceability. Confirm that the ordering suffix HE3 indicates RoHS compliance and lead-free finish before finalizing procurement orders to ensure regulatory adherence.
Selection Notes
Select this component when a PNP digital transistor with integrated biasing is required in an SOT-323 footprint. Ensure the circuit design accommodates the -50 V supply voltage limit and 200 mW power dissipation constraints. Verify that the 2.2 kOhm input resistance aligns with the driving source capabilities and desired switching speeds for the intended application environment.
Part Context
This part belongs to the DTA123 series of pre-biased transistors manufactured by Micro Commercial Components. The HE3 suffix specifically denotes Halogen-free, Eco-friendly, and RoHS-compliant construction. It serves as a compact solution for replacing discrete resistor-transistor combinations in space-constrained printed circuit board layouts.
Replacement Considerations
Direct substitutes must match the PNP polarity, SOT-323 package, and -50 V / -100 mA ratings. Verify equivalent internal resistor values (R1=2.2k, R2=47k) and transition frequency characteristics to maintain circuit performance without redesign.
