Overview
The PDTC144VU,115 is a single NPN resistor-equipped transistor (RET) manufactured by Nexperia USA Inc. It integrates an NPN bipolar junction transistor with built-in bias resistors in a compact SOT-323 (SC-70) surface-mount package. The device features a typical base input resistance (R1) of 47 kOhms and an emitter resistance (R2) of 22 kOhms. Key electrical ratings include a maximum collector-emitter voltage (VCEO) of 50 V and a continuous collector current (IC) of 100 mA. The component operates within a temperature range of -65 °C to +150 °C and has a maximum power dissipation of 200 mW.
Feature Summary
- Integrates NPN transistor with dual bias resistors to simplify circuit design
- Reduces printed circuit board space requirements through component consolidation
- Provides standardized biasing for general-purpose switching applications
Applications
- General purpose switching circuits
- Inverter and interface logic circuits
- Low-power digital driver stages
Procurement Notes
Verify the specific suffix '115' against official Nexperia documentation to confirm the reel packaging configuration and tape-and-reel specifications. Ensure the ordering code matches the required SOT-323 variant. Cross-reference the manufacturer part number with authorized distributor catalogs to validate RoHS compliance status and current production lifecycle stage before procurement.
Selection Notes
Select this component when a single NPN switch requires integrated base biasing without external discrete resistors. Compare the 47 kOhm R1 value against circuit drive requirements to ensure adequate base current. Verify that the SOT-323 thermal dissipation capability meets the application's power constraints. Confirm compatibility with standard surface-mount assembly processes.
Part Context
This part belongs to the Nexperia PDTCx44 series of PNP/NPN resistor-equipped transistors. These devices are designed to replace discrete transistor-resistor networks. The 'VU' designation indicates the specific pinout and resistor values for the SOT-323 package. This series is widely used in consumer electronics and industrial control boards where space efficiency is critical.
Replacement Considerations
Potential substitutes include other NPN RETs with similar 47k/22k resistor ratios in SOT-323 packages, such as the BC847-based equivalents from other manufacturers. Verify pinout compatibility and thermal characteristics before substitution.
