• Provides high switching speed with a transition frequency of 180 MHz.
• Offers robust thermal performance with a maximum operating temperature of +150 °C.

Applications

• Switching applications in consumer electronics
• Logic level interface circuits
• Driver stages for relays or LEDs

Procurement Notes

Verify the specific suffix '115' corresponds to the standard tape-and-reel packaging configuration required for automated assembly processes. Confirm that the SOT-323 footprint matches the target PCB layout dimensions. Ensure compatibility with RoHS 3 directives if applicable to the end product regulations. Cross-reference the manufacturer part number against distributor catalogs to confirm availability and lead times prior to finalizing procurement orders.

Selection Notes

Select this component when a compact PNP solution with built-in biasing is required to minimize external passive components. The SOT-323 package is suitable for space-constrained designs. Consider the 50 V voltage rating and 100 mA current limit to ensure adequate headroom for the intended load. The integrated resistor values should be evaluated against the driving source impedance to guarantee proper saturation and cutoff characteristics.

Part Context

This part belongs to Nexperia's PDTA114 series of Resistor-Equipped Transistors (RETs). These devices combine a single PNP BJT with internal resistors to replace multiple discrete components. The series is designed for general-purpose switching and amplification tasks where simplified schematics and reduced assembly costs are prioritized over customizable external resistance values.

Replacement Considerations

Direct substitutes within the same family include PDTA114EU,115 and PDTA114YU variants. Verify pinout compatibility and identical electrical ratings before substitution. Alternative packages such as SC-70 may require mechanical redesign. Always consult official datasheets to confirm parameter equivalence for critical application requirements.
