The PDTC115EM-QYL is an NPN Resistor-Equipped Transistor (RET) manufactured by Nexperia. It integrates a single NPN transistor with two built-in biasing resistors, R1 and R2, both specified at 100 kΩ. The device is housed in the SOT323 surface-mount plastic package. It features a maximum collector-emitter voltage of 50 V and a continuous collector current rating of 20 mA. The component is qualified to AEC-Q101 standards for automotive applications and supports a junction temperature up to 150 °C.
Verify the specific suffix 'QYL' against official Nexperia documentation to confirm it denotes the correct tape-and-reel packaging format and quality grade. Ensure the part number matches the exact AEC-Q101 qualification requirements for your target application environment.
Select this component when space-constrained designs require integrated base biasing. The 100 kΩ resistor values are suitable for standard logic interface applications. Confirm that the 20 mA current limit and 50 V voltage rating meet the circuit's operational demands.
This part belongs to the PDTC1xx series of NPN RETs. It serves as the complement to PNP variants like the PDTA115EU. The 'Q' designation indicates automotive qualification under AEC-Q101 standards, distinguishing it from standard commercial grade devices within the same electrical family.
Direct substitutes include other AEC-Q101 qualified NPN RETs in SOT323 packages with identical 100 kΩ/100 kΩ internal resistor configurations. Verify pinout compatibility and thermal characteristics before substitution.
