Overview
The DDTA124XUA-7 is a PNP pre-biased small signal surface mount transistor from Diodes Incorporated, housed in an SOT-323 package. It features built-in biasing resistors with nominal values of R1 = 22 kΩ and R2 = 47 kΩ. The device supports a maximum supply voltage of -50 V and a continuous collector current of -100 mA. Power dissipation is rated at 200 mW, with an operating temperature range spanning from -55°C to +150°C. The component utilizes epitaxial planar die construction and complies with RoHS standards.
Feature Summary
- Integrates two distinct biasing resistors (R1≠R2) within the package to simplify circuit design.
- Utilizes epitaxial planar die construction for reliable performance.
- Manufactured using lead-free plating and compliant molding compounds.
Applications
- General-purpose switching applications
- Driver circuits for logic interfaces
- Inverter circuits
Procurement Notes
Verify the specific ordering suffix against official documentation, as variations exist between standard and automotive-grade versions. Confirm availability status directly with the manufacturer or authorized distributors, as production lifecycles may change. Ensure compliance with environmental regulations relevant to the target market before procurement.
Selection Notes
Select this component when a PNP configuration with unequal biasing resistors is required. Verify that the 22 kΩ input resistor and 47 kΩ emitter resistor values align with the specific drive requirements. Ensure the SOT-323 package dimensions fit the available PCB space and thermal constraints.
Part Context
This part belongs to the DDTA (R1≠R2 Series) UA family, which offers various combinations of internal resistors. The DDTA124XUA variant specifically provides the 22 kΩ/47 kΩ ratio. Complemental NPN types are available under the DDTC series designation for designs requiring matched polarity pairs.
Replacement Considerations
Direct substitutes include DDTA124XUA-7-F. Other compatible options within the same series include DDTA123YUA and DDTA123JUA, provided their respective resistor ratios meet the circuit requirements.
