PDTA114YK,115

Overview

The PDTA114YK,115 is a PNP digital transistor manufactured by NXP USA Inc., belonging to the PDTC/PDTA series of Resistor-Equipped Transistors (RETs). It integrates a single PNP bipolar junction transistor with two built-in biasing resistors in a compact SOT-323 surface-mount package. The device features a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Key electrical parameters include a DC current gain (hFE) of at least 100 at 5 mA and 5 V, a saturation voltage of 100 mV at 5 mA collector current, and a transition frequency of 230 MHz. The internal resistor network consists of a base resistor (R1) of 10 kOhms and an emitter resistor (R2) of 47 kOhms.

Feature Summary

• Integrates a PNP transistor with dual biasing resistors to reduce component count and PCB space.
• Provides high-speed switching capabilities suitable for logic interface applications.
• Ensures consistent performance through integrated resistor matching within the RET architecture.

Applications

• Logic level translation between different voltage domains.
• Driver circuits for low-current loads such as LEDs or relays.
• Pull-up or pull-down implementations in digital logic interfaces.

Procurement Notes

Verify the specific suffix 'YK' against official Nexperia/NXP documentation to confirm exact resistor values and tape-and-reel specifications. Ensure compatibility with RoHS3 standards if required by the target assembly process. Confirm that the SOT-323 package dimensions align with the designated footprint on the printed circuit board layout prior to procurement.

Selection Notes

Select this component when a PNP configuration with specific 10k/47k biasing ratios is required for space-constrained designs. Compare the 230 MHz transition frequency against application speed requirements. Evaluate the 100 mA collector current limit against load demands. Consider the SOT-323 thermal dissipation characteristics relative to ambient operating conditions and power derating curves provided in the datasheet.

Part Context

This part belongs to the PDTA/PDTC family of Resistor-Equipped Transistors from NXP Semiconductors. These devices are designed to simplify circuit design by replacing discrete transistors and multiple resistors with a single surface-mount component. The family offers various configurations including NPN and PNP types with different resistor values and packaging options like SOT-323 and SC-70.

Replacement Considerations

Direct pin-compatible substitutes may include other PNP digital transistors in SOT-323 packages with similar 50V ratings and 100mA current capacity. Verify equivalent internal resistor values (R1=10k, R2=47k) and hFE characteristics. Cross-reference with Nexperia's official replacement guide for validated alternatives.
