Overview
The PDTA144WK,115 is a PNP resistor-equipped transistor from the PDTA144W series manufactured by Nexperia. It integrates bias resistors R1 (47 kΩ) and R2 (22 kΩ) to simplify circuit design. The device operates in an SOT346 (SC-59) plastic surface-mounted package with three leads. Key electrical parameters include a collector-emitter voltage of -50 V, a DC output current of -100 mA, and a total power dissipation of 250 mW at 25 °C ambient temperature. The junction temperature maximum is 150 °C.
Feature Summary
- Integrates built-in bias resistors to reduce component count and simplify circuit design.
- Reduces pick and place costs during manufacturing assembly.
Applications
- General purpose switching and amplification
- Inverter and interface circuits
- Circuit driver
Procurement Notes
Verify the ordering suffix '115' against the manufacturer's official documentation to confirm the specific reel or tape configuration associated with this part number. Ensure the source document explicitly links this suffix to the SOT346 package variant. Confirm that the datasheet status remains as 'Product data sheet' for production specifications before finalizing procurement plans.
Selection Notes
Select the PDTA144WK when a compact PNP transistor solution with integrated biasing is required for space-constrained designs. The SOT346 package offers a small footprint suitable for surface-mount applications. Verify that the 47 kΩ input resistor and 22 kΩ emitter resistor values align with the specific base drive requirements of the target application circuit.
Part Context
This component belongs to the PDTA144W series of PNP resistor-equipped transistors. The series includes various package options such as SOT23, SOT323, and SOT883. The PDTA144WK specifically utilizes the SOT346 (SC-59) package format. The product line is designed to replace discrete resistor-transistor networks in general-purpose switching applications.
Replacement Considerations
Check for direct pin-compatible alternatives within the same series, such as PDTA144WT or PDTA144WU, if different package footprints are acceptable. Verify that any substitute maintains the same R1 and R2 resistance values and PNP polarity to ensure circuit functionality remains unchanged.
