Nexperia USA Inc. PDTA114EQC-QZ

Overview

PDTA114EQC-Q from Nexperia is a 50 V, 100 mA PNP resistor-equipped transistor (RET) in a DFN1412D-3 (SOT8009) leadless package with side-wettable flanks. It integrates 10 kΩ input and 10 kΩ emitter-base bias resistors, delivers −100 mA output current, exhibits −50 V collector-emitter breakdown voltage, and is AEC-Q101 qualified for automotive digital switching applications such as IC input control and load switching.

For engineers reviewing the PDTA114EQC-Q datasheet, PDTA114EQC-Q pinout, PDTA114EQC-Q application, or PDTA114EQC-Q equivalent, this part serves as a space-optimized, AOI-compatible replacement for BC857-Q series transistors in cost-sensitive, high-reliability digital logic interfaces requiring simplified biasing and reduced component count.

Technical Context

This PNP RET integrates two monolithic silicon resistors-R1 = 10 kΩ between base and input terminal, R2 = 10 kΩ between base and emitter-to eliminate external bias components. Its internal transistor operates with DC current gain (h_FE) ≥30 at −10 mA collector current and −5 V V_CE, enabling robust digital on/off switching without external base drive circuitry.

The device features low saturation voltage (V_CE(sat) ≤ −100 mV at I_C = −10 mA, I_B = −0.5 mA), off-state input voltage (V_I(off)) of −1.1 V to −0.8 V, and on-state input voltage (V_I(on)) of −2.5 V to −1.8 V, supporting direct interfacing with 3.3 V and 5 V logic families while maintaining noise immunity and stable turn-off behavior.

FAQ

What is the maximum ambient temperature for continuous operation?

The PDTA114EQC-Q supports continuous operation from −55 °C to +150 °C ambient temperature, with junction temperature limited to 150 °C. Derated power dissipation applies above 25 °C ambient - for example, total power drops to 360 mW at 70 °C ambient on standard FR4 PCB with 35 µm copper.

Can this part replace a standard BC857B in an existing design?

Yes, but with schematic modification: PDTA114EQC-Q integrates 10 kΩ base resistors and uses a three-terminal RET configuration (input/base, GND/emitter, output/collector), whereas BC857B is a two-terminal discrete PNP requiring external base bias. Layout changes and logic polarity verification are necessary for drop-in substitution.

Is the DFN1412D-3 package compatible with standard reflow profiles?

Yes - the DFN1412D-3 (SOT8009) package is qualified for lead-free reflow soldering per JEDEC J-STD-020. Recommended stencil thickness is 0.1 mm, and the footprint matches IPC-7351B density level 'N'. Side-wettable flanks enable post-reflow AOI verification of solder joint integrity.

What is the typical transition frequency (f_T) of the internal transistor?

The internal PNP transistor has a typical transition frequency f_T of 180 MHz at V_CE = −5 V, I_C = −10 mA, and f = 100 MHz. This value reflects the intrinsic high-frequency capability of the bare die, though the RET configuration is optimized for DC/digital switching-not RF amplification.
