Overview
The PDTC144WU,115 is an NPN resistor-equipped transistor (RET) manufactured by Nexperia. It integrates a single NPN transistor with built-in bias resistors R1 and R2 in a SOT323 (SC-70) surface-mount package. The device features a collector-emitter voltage (VCEO) of 50 V and a continuous DC output current (IO) of 100 mA. Typical internal resistance values are 47 kΩ for R1 and 22 kΩ for R2. Total power dissipation is rated at 200 mW at 25 °C ambient temperature. The junction temperature maximum is 150 °C, with an operating ambient range from -65 °C to +150 °C.
Feature Summary
- Integrates NPN transistor with built-in bias resistors to simplify circuit design
- Reduces component count and pick-and-place costs
- Small SOT323 (SC-70) plastic surface-mounted package
Applications
- General purpose switching and amplification
- Inverter and interface circuits
- Circuit driver
Procurement Notes
Verify the specific ordering suffix against official Nexperia documentation to confirm manufacturing origin and compliance status. Confirm that the SOT323 package variant matches the required footprint for PCB layout. Ensure thermal management aligns with the 200 mW total power dissipation limit under expected operating conditions.
Selection Notes
Select this component when a compact NPN solution with integrated biasing is required. The fixed 47 kΩ input resistor and 22 kΩ emitter resistor define the biasing characteristics. Verify that the 100 mA current rating and 50 V voltage limits accommodate the target application's electrical requirements without exceeding absolute maximum ratings.
Part Context
This part belongs to the PDTC144W series of NPN resistor-equipped transistors. The 'W' indicates the series family, while 'U' specifies the SOT323 (SC-70) package. The ',115' suffix denotes the specific tape and reel packaging configuration provided by Nexperia.
Replacement Considerations
The PDTA144WU is the PNP complement within the same series. Other packages in the PDTC144W series include SOT23 (PDTC144WT) and SOT883 (PDTC144WM), which share identical electrical characteristics but require different footprints.
