Overview
The PDTC144ET-Q is an NPN Resistor-Equipped Transistor (RET) housed in a small SOT23 (TO-236AB) surface-mounted device plastic package. It features built-in bias resistors with R1 = 47 kΩ and R2 = 47 kΩ, providing a typical resistor ratio of 1. The device supports a collector-emitter voltage (VCEO) of 50 V and an output current capability of 100 mA. Qualified according to AEC-Q101, it operates within a junction temperature range of -65 °C to +150 °C and has a total power dissipation of 250 mW at 25 °C ambient temperature.
Feature Summary
- Built-in bias resistors simplify circuit design and reduce component count
- AEC-Q101 qualified for automotive applications
- SOT23 surface-mount package reduces pick and place costs
Applications
- Digital applications in automotive and industrial segments
- Cost-saving alternative for BC847-Q series in digital applications
- Controlling IC inputs
- Switching loads
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging details such as reel size or tape width. Confirm that the requested variant matches the required AEC-Q101 qualification status if intended for automotive use. Ensure compatibility with standard SOT23 footprints during procurement planning.
Selection Notes
Select this component when a compact NPN switching solution with integrated biasing is required. The built-in 47 kΩ input resistor simplifies drive circuits. Verify that the 50 V collector-emitter voltage rating meets the application's maximum operating voltage requirements. Consider the thermal resistance characteristics for high-temperature environments.
Part Context
This part belongs to Nexperia's family of resistor-equipped transistors designed to replace discrete resistor-transistor networks. The PDTC144ET-Q serves as the NPN complement to the PDTA144ET PNP variant. It is engineered to minimize board space and assembly complexity in digital logic and interface circuits.
Replacement Considerations
The PDTA144ET is the PNP complement within the same product family. For direct functional substitution in NPN configurations, verify pinout compatibility and electrical ratings against the original design specifications.
