Overview
The PDTC124EU is an NPN Resistor-Equipped Transistor (RET) housed in a SOT323 (SC-70) surface-mount package. It integrates bias resistors R1 and R2, both nominally 22 kΩ with a ratio of 1. The device supports a collector-emitter voltage (VCEO) of 50 V and a continuous output current of 100 mA. Key electrical characteristics include a DC current gain (hFE) minimum of 60 at 5 mA, a transition frequency (fT) of 230 MHz, and a total power dissipation of 200 mW at 25 °C ambient temperature. Operating temperatures range from -65 °C to +150 °C.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design and reduce component count.
- Provides high breakdown voltage capability for robust digital switching applications.
- Offers cost-saving alternative to discrete transistor configurations.
Applications
- Digital applications in industrial segments
- Controlling IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel size or tape width. Confirm RoHS compliance status and ensure the selected variant matches the required lead-free specifications for your assembly process before finalizing procurement orders.
Selection Notes
Select this component when a compact NPN solution with integrated base biasing is required. Ensure the application voltage does not exceed the 50 V collector-emitter rating. Verify that the 22 kΩ input resistor value aligns with the driving source impedance and desired logic threshold levels for the target digital interface.
Part Context
This part belongs to Nexperia's NPN Resistor-Equipped Transistor family, designed to replace multiple discrete components. The PDTC124EU serves as the NPN counterpart to the PDTA124EU PNP complement. It is distinct from automotive-qualified variants, which carry specific -Q suffixes and undergo different qualification standards.
Replacement Considerations
Direct functional substitutes within the same package include other NPN RETs with similar 22 kΩ bias ratios, such as the BC847 series equivalents if discrete resistance values are acceptable. For automotive replacements, consider Nexperia parts with AEC-Q101 qualification.
