PDTC114YM-QYL

Overview

The PDTC114YM-QYL is an NPN resistor-equipped transistor (RET) from Nexperia, designed for digital applications. It features a built-in base resistor of 10 kOhms and an open emitter connection. The device supports a maximum collector-emitter voltage of 50 V and a continuous collector current of 100 mA. Key electrical parameters include a DC current gain (hFE) of at least 100 at 5 mA and 5 V, with a saturation voltage of 100 mV max at 250 µA base and 5 mA collector current. It operates within a junction temperature range of -55°C to +150°C and is housed in an SOT363 package.

Feature Summary

• Integrated base resistor simplifies circuit design by reducing component count
• Qualified for automotive applications under AEC-Q101 standards
• High breakdown voltage capability ensures reliable operation in demanding environments

Applications

• Digital logic interface circuits
• Switching loads in automotive systems
• Controlling IC inputs

Procurement Notes

Verify the specific suffix YM-QYL against official Nexperia documentation to confirm the exact package type and automotive qualification status. Ensure compatibility with existing PCB footprints, particularly regarding the SOT363 outline dimensions. Confirm RoHS compliance and lead-free status through the manufacturer's latest datasheet or certification documents before finalizing procurement.

Selection Notes

Select this component when a compact NPN solution with integrated biasing is required for space-constrained designs. The AEC-Q101 qualification makes it suitable for automotive electronics where reliability is critical. Compare the 10 kOhm internal resistance against other RET variants to ensure proper base drive current requirements are met for the intended switching speed and load conditions.

Part Context

This part belongs to Nexperia's PDTC114 series of pre-biased transistors. The QYL suffix typically denotes automotive grade qualification and a specific surface-mount package variant, distinguishing it from standard commercial versions like the PDTC114YU. It serves as a direct replacement for discrete resistor-transistor networks in digital switching applications.

Replacement Considerations

Direct substitutes include other PDTC114 series variants with matching R1 values, such as PDTC114YU or PDTC114ET, provided the package footprint is compatible. Verify that alternative parts meet the same AEC-Q101 requirements if used in automotive contexts. Check pinout configurations to ensure interchangeability without PCB redesign.
