Overview
The ADA123JUQ-7 is a dual PNP pre-biased digital transistor manufactured by Diodes Incorporated. It integrates two PNP transistors with built-in biasing resistors in a compact SOT-363 surface-mount package. The device features a collector-emitter voltage (VCEO) of 50 V and a continuous collector current of 100 mA, with a power dissipation rating of 270 mW. Typical internal resistor values are 2.2 kΩ for the base resistor (R1) and 47 kΩ for the emitter-base resistor (R2). It operates within a temperature range of -55°C to +150°C and includes an hFE minimum of 80.
Feature Summary
- Dual PNP configuration with integrated biasing resistors simplifies circuit design by eliminating external components.
- Compact SOT-363 package provides space-efficient mounting for high-density applications.
- High thermal stability supports operation across a wide industrial temperature range.
Applications
- Interface circuits requiring signal inversion or buffering.
- Driver stages for low-power loads and logic level translation.
- Switching applications in consumer electronics and industrial control systems.
Procurement Notes
Verify component authenticity through authorized Diodes Incorporated distributors. Confirm RoHS compliance and AEC-Q101 qualification status if automotive reliability is required. Ensure storage conditions adhere to moisture sensitivity levels specified in the datasheet to prevent package damage during soldering processes.
Selection Notes
Select this component when a dual PNP solution with fixed bias ratios is needed. Compare R1/R2 values against target input impedance requirements. Verify that the 50 V breakdown voltage exceeds peak circuit voltages. Consider the SOT-363 footprint constraints relative to available PCB real estate.
Part Context
This part belongs to the ADA123 series of pre-biased transistors from Diodes Incorporated. It serves as a complementary counterpart to NPN variants like the ADT123 series. The series is designed to replace discrete resistor-transistor networks, reducing board space and assembly complexity in modern electronic designs.
Replacement Considerations
Direct substitutes include other dual PNP digital transistors in SOT-363 packages with matching 50V ratings and similar resistor values. Verify pinout compatibility and thermal characteristics before substitution.
