Overview
The PDTC114YK,115 is a single NPN digital transistor manufactured by Nexperia USA Inc. under the NXP brand portfolio. It integrates an NPN bipolar junction transistor with built-in bias resistors in a compact SOT-323 surface-mount package. The device features a collector-emitter breakdown voltage of 50 V and a maximum continuous collector current of 100 mA. Internal resistor values are specified as R1 (base) at 10 kOhms and R2 (emitter) at 47 kOhms. Key electrical parameters include a DC current gain (hFE) of 100 at 5 mA/5 V, a saturation voltage of 100 mV at 250 µA base current, and a transition frequency of 230 MHz. Power dissipation is rated at 200 mW.
Feature Summary
- Integrates NPN transistor with fixed bias resistors to simplify circuit design
- Provides high switching speed suitable for digital logic applications
- Offers low saturation voltage for efficient power handling
Applications
- General-purpose switching in digital logic circuits
- Driver stages for small-signal loads
- Level shifting interfaces between microcontrollers and peripherals
Procurement Notes
Verify the specific suffix '115' against official Nexperia documentation to confirm tape-and-reel packaging specifications. Ensure the component source is traced directly to Nexperia or authorized distributors to avoid counterfeit parts. Cross-reference the part number with the latest datasheet revision to confirm RoHS compliance status and pinout configuration before procurement.
Selection Notes
Select this component when a compact NPN switch with integrated biasing is required. The 10 kOhm base resistor and 47 kOhm emitter resistor define the input impedance and drive requirements. Compare the 230 MHz transition frequency against system clock speeds to ensure adequate performance margins for the intended switching application.
Part Context
This component belongs to the PDTC114 series of Resistor-Equipped Transistors (RETs). It shares the same internal schematic and electrical characteristics as the PDTC114YU variant, differing primarily in packaging or manufacturing lot codes. The series is designed to replace discrete resistor-transistor networks, reducing board space and assembly complexity.
Replacement Considerations
The PDTC114YU,115 is a confirmed equivalent part with identical pinout and electrical specifications. Verify that any alternative substitute maintains the 10 kOhm/47 kOhm resistor ratio and SOT-323 footprint compatibility.
