Overview
The PDTA124ET,235 is a PNP Resistor-Equipped Transistor (RET) housed in an SOT23 surface-mounted package. It integrates a single transistor with built-in bias resistors R1 and R2, both nominally 22 kΩ. The device supports a collector-emitter voltage of -50 V and a continuous output current of -100 mA. Total power dissipation is rated at 250 mW at 25 °C ambient temperature. The junction temperature range extends from -65 °C to +150 °C. This component is qualified under the AEC-Q101 standard for automotive applications.
Feature Summary
- Integrates built-in bias resistors to reduce component count and simplify circuit design.
- Provides a cost-saving alternative to discrete BC847/857 series transistors in digital applications.
- Qualified for automotive use according to AEC-Q101 standards.
Applications
- Digital applications in automotive segments
- Control of IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm packaging details such as tape width and reel quantity. Ensure the requested part number matches the exact package type required for the PCB footprint. Confirm RoHS compliance status through the manufacturer's latest product data sheet before finalizing procurement orders.
Selection Notes
Select this component when a compact PNP switching solution with integrated base biasing is required. The SOT23 package offers a small form factor suitable for space-constrained designs. Verify that the 22 kΩ internal resistor values align with the target logic levels and drive requirements of the connected control signals.
Part Context
This part belongs to the PDTA124E series of PNP resistor-equipped transistors. Other variants in this family include the PDTA124EE in SOT416, PDTA124EM in SOT883, and PDTA124EU in SOT323 packages. All variants share identical electrical characteristics but differ in physical dimensions and thermal performance profiles.
Replacement Considerations
PDTC124ET is the NPN complement within the same RET family. For direct functional replacement in existing circuits, verify polarity requirements and ensure the substitute maintains compatible voltage and current ratings.
