PDTC114YE,115

Overview

The PDTC114YE,115 is a single NPN pre-biased digital transistor manufactured by Nexperia USA Inc. It integrates an NPN silicon transistor with two internal bias resistors in a compact SOT-323 (SC-70) surface-mount package. The device features a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Internal resistance values are typically 10 kOhms for the base resistor (R1) and 47 kOhms for the emitter resistor (R2). 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 250 µA base and 5 mA collector currents, and a transition frequency of 230 MHz. Maximum power dissipation is rated at 200 mW.

Feature Summary

• Integrates NPN transistor with built-in bias resistors to simplify circuit design
• Eliminates external input resistors for inverter configuration
• Thin-film resistors provide isolation and minimize parasitic effects

Applications

• General-purpose switching applications
• Inverter circuits requiring minimal external components
• Low-voltage logic interface buffering

Procurement Notes

Verify the manufacturer designation as Nexperia USA Inc., resulting from the separation of NXP's semiconductor division. Confirm the specific ordering code PDTC114YE,115 corresponds to the SOT-323 package variant. Ensure compliance with RoHS3 standards and AEC-Q101 qualification requirements if applicable to the target environment. Cross-reference datasheet revisions for any changes in mechanical dimensions or electrical limits.

Selection Notes

Select this component when space-constrained designs require a single NPN switch with integrated biasing. The SOT-323 package offers a small footprint suitable for dense PCB layouts. Verify that the 10 kOhm base resistance aligns with the driving source impedance and required switching speed. Consider the 200 mW power dissipation limit relative to ambient temperature derating curves for thermal management.

Part Context

This part belongs to the PDTC114 series of Resistor-Equipped Transistors (RETs). It is functionally similar to other NPN pre-biased transistors like the PDTC114YU but differs in packaging. The 'YE' suffix typically denotes the SOT-323 package format, distinguishing it from other variants such as SC-76 or SOD882. It serves as a drop-in replacement for discrete resistor-transistor networks in standard logic applications.

Replacement Considerations

Publicly confirmed substitute part numbers include PDTC114YU,115 and PDTA114YU,115 (PNP counterpart). Other compatible RETs from different manufacturers may be considered if pinout and electrical specifications match exactly.
