Nexperia USA Inc. PDTA114YQAZ

Overview

PDTA114YQAZ from Nexperia is a 50 V, −100 mA PNP resistor-equipped transistor (RET) in a DFN1010D-3 (SOT1215) package, integrating 10 kΩ input bias resistor (R1) and 47 kΩ feedback resistor (R2). It functions as a single-chip digital switch for low-power logic interfacing, with −100 mV V_CE(sat) at −5 mA/−0.25 mA drive and AEC-Q101 qualification for automotive body electronics.

For engineers reviewing the PDTA114YQAZ datasheet, PDTA114YQAZ pinout, PDTA114YQAZ application, or PDTA114YQAZ equivalent, key selection criteria include its −6 V V_EB0, −40 V to +6 V input voltage range, 100× DC current gain at −5 mA, ultra-thin 0.37 mm profile, and AOI-compatible side-pads - all critical for space-constrained, high-reliability digital control nodes.

Technical Context

This RET integrates a PNP bipolar transistor with two monolithically embedded thin-film resistors: R1 (10 kΩ) connects base to input, and R2 (47 kΩ) connects base to emitter to enable self-biasing and eliminate external components. Its operation relies on controlled base current injection through R1, with R2 stabilizing the operating point against temperature drift and β variation.

The device operates in saturation switching mode with guaranteed −100 mV V_CE(sat) at I_C = −5 mA and I_B = −0.25 mA, and supports off-state input voltages from −0.7 V to −0.5 V - enabling robust noise immunity in 3.3 V and 5 V logic systems. Its 3 pF collector capacitance and 180 MHz f_T support fast edge transitions in digital signal routing.

FAQ

What is the maximum allowable input voltage for PDTA114YQAZ?

The absolute maximum input voltage (V_I) is −40 V to +6 V, as specified in Table 6. This range accommodates negative transients common in automotive 12 V systems and ensures safe operation with standard 3.3 V and 5 V logic families without external clamping diodes.

Can PDTA114YQAZ replace BC857 in existing designs?

Yes - as a drop-in replacement in most digital switching roles, provided the PCB layout accommodates the DFN1010D-3 footprint and the application requires sinking (not sourcing) current. Its integrated 10 kΩ/47 kΩ bias network eliminates two external resistors, simplifying layout and improving consistency.

Is thermal derating required for continuous operation at 100 mA?

At ambient temperatures above 25 °C, power derating applies: P_tot decreases linearly from 440 mW (4-layer PCB) with slope −3.5 mW/°C above 25 °C. At 100 mA and −100 mV V_CE(sat), power dissipation is 10 mW - well within safe limits even at 125 °C ambient.

Does PDTA114YQAZ support automatic optical inspection (AOI)?

Yes - its DFN1010D-3 package features side-wettable flanks (visible solderable side pads), enabling reliable AOI detection of solder joint quality without requiring X-ray inspection, which reduces manufacturing cost and improves first-pass yield.
