Overview
The PDTC144EK,115 is an NPN resistor-equipped transistor from the PDTC144E series manufactured by NXP USA Inc. It integrates two bias resistors, R1 and R2, both with a typical value of 47 kΩ, into a single SC-59 (SOT346) package. The device supports a maximum collector-emitter voltage (VCEO) of -50 V and a DC output current (IO) of -100 mA. Key electrical characteristics include a DC current gain (hFE) of at least 80 at IC = 5 mA, a collector-emitter saturation voltage (VCEsat) of 150 mV at IC = 10 mA, and a thermal resistance (Rth(j-a)) of 500 K/W in free air. The component is designed for general-purpose switching and amplification applications.
Feature Summary
- Integrates built-in bias resistors to simplify circuit design
- Reduces component count and board space requirements
- Eliminates external resistor placement costs
Applications
- General purpose switching and amplification
- Inverter and interface circuits
- Circuit driver applications
Procurement Notes
Verify the specific ordering suffix
Selection Notes
Select the PDTC144EK variant when the SC-59 (SOT346) surface-mount package is required for the design. Ensure the application operates within the specified -50 V collector-emitter voltage and -100 mA DC output current limits. Consider the 500 K/W thermal resistance for heat dissipation calculations under standard mounting conditions. Verify that the integrated 47 kΩ bias resistors meet the circuit's input impedance requirements.
Part Context
The PDTC144EK belongs to the PDTC144E series of NPN resistor-equipped transistors produced by Philips Semiconductors, now NXP. This series consolidates discrete transistors and biasing resistors into compact packages such as SC-75, SC-89, SC-59, and SC-101. The PDTC144EK specifically utilizes the SOT346 outline, providing a standardized solution for replacing multiple discrete components in low-power switching and logic interface designs.
Replacement Considerations
The PNP complement PDTA144EK serves as the counterpart for complementary circuit designs. Other packages in the PDTC144E series, such as PDTC144EE (SC-75) or PDTC144EM (SC-101), offer identical electrical performance but require different footprint layouts.
