The PDTC123YM-QYL is an NPN Resistor-Equipped Transistor (RET) from Nexperia, designed for digital switching applications. It integrates a single base resistor (R1) of 47 kΩ within the device. The component features a maximum collector-emitter voltage (VCEO) of 50 V and supports a continuous collector current (Ic) of 100 mA. It operates with a power dissipation rating of 200 mW and includes built-in resistors to simplify circuit design. The transistor is housed in a compact SOT363 surface-mount package, suitable for automated assembly processes.
Verify the specific suffix QYL against official Nexperia documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the SOT363 package. Confirm RoHS compliance status through the manufacturer's latest product change notifications before finalizing procurement orders.
Select this component when a pre-biased NPN transistor with a 47 kΩ base resistor is required. It serves as a direct replacement for discrete BJT and resistor combinations in space-constrained designs. Consider the 50 V breakdown voltage and 100 mA current limits to ensure adequate headroom for the target application's electrical requirements.
This part belongs to the PDTC123 series of NPN resistor-equipped transistors. The family offers various base resistance values and packaging options. The QYL suffix indicates specific manufacturing and packaging details defined by Nexperia for this particular variant within the broader RET portfolio.
Direct substitutes include other PDTC123 variants with matching 47 kΩ base resistance and compatible packages. Verify pinout compatibility and electrical ratings against alternatives such as PDTC123YM or similar Nexperia RETs before implementation.
