PDTA114EQCZ

Overview

The PDTA114EQCZ is a PNP Resistor-Equipped Transistor (RET) from Nexperia, housed in an ultra-small DFN1412D-3 (SOT8009) leadless package with side-wettable flanks. It features built-in bias resistors of 10 kΩ each for R1 and R2. The device supports a collector-emitter voltage (VCEO) of -50 V and a continuous output current (IO) of -100 mA. Key electrical characteristics include a DC current gain (hFE) minimum of 30 at IC = -10 mA and VCE = -5 V, a transition frequency (fT) typical value of 180 MHz, and a collector-emitter saturation voltage (VCEsat) maximum of -100 mV at IC = -10 mA. The junction-to-ambient thermal resistance is 348 K/W in free air.

Feature Summary

• Integrates dual 10 kΩ bias resistors to simplify circuit design and reduce component count.
• Utilizes a low-profile DFN1412D-3 package with side-wettable flanks suitable for Automatic Optical Inspection (AOI).
• Provides high-speed switching capability with a typical transition frequency of 180 MHz.

Applications

• Digital logic applications requiring signal inversion or buffering.
• Cost-effective replacement for BC857 series transistors in digital circuits.
• Direct interfacing and controlling of IC inputs.
• Low-power load switching operations.

Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel quantity and packaging variant. Confirm that the DFN1412D-3 footprint aligns with the target PCB stencil design, particularly regarding the side-wettable flank soldering requirements. Ensure compliance with RoHS directives and check for any specific automotive qualification status if intended for such environments.

Selection Notes

Select this component when space constraints necessitate a leadless package smaller than SOT23. The 10 kΩ internal resistor values are optimal for standard TTL/CMOS logic levels. Consider the 0.5 mm height profile for thin-form-factor designs. Verify that the -50 V rating meets the system's voltage headroom requirements and that the thermal dissipation capabilities are sufficient for the expected duty cycle.

Part Context

This part belongs to the PDTA143/114/124/144EQC series, which shares the same SOT8009 package but varies in internal resistor values. The PDTA114EQC specifically offers symmetric 10 kΩ resistors, distinguishing it from the PDTA143 (4.7 kΩ) and PDTA144 (47 kΩ) variants within the same family.

Replacement Considerations

PDTC114EQC is the NPN complement within the same series. For direct pin-compatible replacements with different resistor values, consider PDTA143EQC or PDTA144EQC. Legacy SOT23 packages like PDTA114TT offer similar functionality but with larger physical dimensions.
