PDTC114EQBZ

Overview

The PDTC114EQBZ is an NPN Resistor-Equipped Transistor (RET) from Nexperia, housed in a DFN1110D-3 (SOT8015) leadless package with side-wettable flanks. It features built-in bias resistors R1 and R2, both nominally 10 kΩ. Key electrical parameters include a collector-emitter voltage of 50 V, a maximum output current of 100 mA, and a total power dissipation of 340 mW at 25 °C on a standard FR4 PCB. The device exhibits a transition frequency of 230 MHz and a DC current gain of at least 30 at 10 mA.

Feature Summary

• Integrates bias resistors to simplify circuit design and reduce component count
• Ultra-small footprint with low profile suitable for high-density layouts
• Side-wettable flanks facilitate Automatic Optical Inspection (AOI) of solder joints

Applications

• Digital applications
• Controlling IC inputs
• Switching loads

Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel or cut-tape configuration. Confirm the marking code corresponds to the intended revision level. Ensure the supplier provides traceability documentation consistent with Nexperia's quality standards. Check for any recent Product Change Notices affecting the SOT8015 package variant.

Selection Notes

Select this RET when space constraints preclude discrete transistor-resistor combinations. The 10 kΩ resistor ratio suits general digital switching where moderate base drive is sufficient. Compare thermal resistance values against the application's ambient temperature requirements to ensure junction temperatures remain within limits during continuous operation.

Part Context

This component belongs to the PDTC143/114/124/144EQB series, which shares the same DFN1110D-3 package but varies in internal resistor values. It serves as a compact alternative to traditional SOT323 or SOT23 packages, offering improved solder joint visibility due to its side-wettable flank design while maintaining similar electrical performance characteristics.

Replacement Considerations

Direct substitutes include other PDTC114 variants in different packages such as PDTC114YU (SOT323). Verify pin compatibility and thermal dissipation capabilities when replacing with devices from other manufacturers or different Nexperia families.
