Overview
The DTA124E is a PNP Silicon Surface Mount Transistor with a monolithic bias resistor network, designed to replace discrete devices and external resistor bias networks. It integrates a single transistor with two resistors: a series base resistor (R1) and a base-emitter resistor (R2). Key electrical parameters include a collector current of -0.1 A, a collector-emitter voltage of -50 V, and a power dissipation of 0.15 W. The device features an input resistance R1 of 22 kΩ and an emitter-base resistance R2 of 22 kΩ. It operates within a storage temperature range of -55°C to 150°C and has a minimum DC current gain (hFE) of 56.
Feature Summary
- Integrates a PNP transistor with monolithic bias resistors to simplify circuit design and reduce board space.
- Eliminates the need for external input resistors, allowing easy configuration of inverter circuits by setting only on/off conditions.
- Available in surface mount packages such as SOT-416 (EMT3) and SOT-723 (VMT3), suitable for wave or reflow soldering.
Applications
- Inverter circuits
- Interface applications
- Driver circuits
Procurement Notes
Verify the specific suffix (e.g., EE3, EMHZG, EKA) to confirm the package type and automotive qualification status. The base part number DTA124E may refer to multiple variants; ensure the selected variant matches the required packaging and reliability standards for the target application.
Selection Notes
Select the appropriate package code based on board space constraints and soldering process requirements. Confirm whether automotive grade certification (AEC-Q101) is necessary, as this applies only to specific suffixes like EMHZG. Ensure the 22 kΩ resistor values align with the intended biasing requirements for the digital switching application.
Part Context
The DTA124E belongs to the Bias Resistor Transistor (BRT) family from onsemi. These devices are engineered to consolidate discrete components into a single surface-mount package, enhancing reliability and reducing assembly complexity. The product line includes complementary NPN types and various resistor configurations to support diverse digital logic and switching needs.
Replacement Considerations
Complementary NPN types are available in the DTC124E series. Other manufacturers offer equivalent BRTs, but pinout and resistor tolerance variations must be verified before substitution.
