Product details
Overview
PDTA114YQC from Nexperia is a 50 V, 100 mA PNP resistor-equipped transistor (RET) in a DFN1412D-3 (SOT8009) leadless SMD package with side-wettable flanks. It integrates R1 = 10 kΩ and R2 = 47 kΩ bias resistors, delivers hFE ≥ 100 at IC = −5 mA / VCE = −5 V, achieves VCE(sat) ≤ −100 mV, and is optimized for digital switching and IC input control in space-constrained PCBs.
For engineers reviewing the PDTA114YQC datasheet, PDTA114YQC pinout, PDTA114YQC application, or PDTA114YQC equivalent, this device serves as a drop-in replacement for BC857-series transistors where integrated base biasing simplifies layout, reduces BOM count, and supports AOI-compatible solder joint inspection in high-density consumer and industrial control boards.
Technical Context
This PNP RET uses an internal silicon transistor with built-in R1–R2 resistor network configured for fixed-current biasing: R1 connects base to input, R2 shunts base to emitter, enabling single-pin drive and predictable turn-on/turn-off thresholds. Its −6 V VEBO rating and −40 V to +6 V VI(on)/VI(off) range ensure robust noise immunity in 3.3 V and 5 V logic interfaces.
The DFN1412D-3 package features side-wettable flanks for automated optical inspection of solder joints, 0.48 mm body height, and thermal resistance Rth(j-a) = 278 K/W on 70 µm FR4 copper-enabling reliable operation up to 150 °C junction temperature under pulsed 100 mA loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage before breakdown; enables use in 24 V rail switching and level-shifted signal paths. |
| IO | −100 mA: Continuous output current capability; sufficient for driving LEDs, small relays, and logic inputs without external current limiting. |
| R1 / R2 | 10 kΩ / 47 kΩ: Precisely trimmed on-die resistors; eliminate need for two external bias components and reduce layout sensitivity to parasitic capacitance. |
| hFE | ≥100 @ IC = −5 mA, VCE = −5 V: High DC current gain ensures low base drive current (≤0.25 mA), easing sourcing from microcontroller GPIOs. |
| VCE(sat) | ≤ −100 mV @ IC = −5 mA, IB = −0.25 mA: Ultra-low saturation voltage minimizes power loss (<0.5 mW) and heat generation in always-on or high-duty-cycle switches. |
| VI(on) / VI(off) | −1.4 V to −0.8 V / −0.7 V to −0.5 V: Defined input voltage thresholds enable clean logic-level compatibility with TTL and CMOS outputs across temperature. |
| Ptot | 450 mW @ Tamb ≤ 25 °C (70 µm Cu): Sustains full-load operation on standard FR4 without heatsinking in ambient temperatures up to 75 °C. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, leadless plastic package measuring 1.4 × 1.2 × 0.48 mm with side-wettable flanks for AOI-compatible reflow soldering. Its ultra-low 0.5 mm profile supports thin-profile portable electronics and high-density routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Driven directly by logic signal; internal R1 connects here to base node-no external pull-up/down required. |
| 2 | GND (emitter) | Emitter tied to system ground; provides return path for load current and reference for R2 resistor. |
| 3 | Output (collector) | Switches high-side loads referenced to VCC; sinks current when active; compatible with open-collector interface standards. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | On-die 10 kΩ (R1) and 47 kΩ (R2) resistors replace two discrete components-reducing PCB area by >0.8 mm² and eliminating placement misalignment risk. |
| Side-wettable flanks | Exposed copper sidewalls on all three terminals enable automated optical inspection of solder fillets-critical for zero-defect manufacturing in Class III assemblies. |
| Low VCE(sat) | ≤ −100 mV at rated current ensures <1% voltage drop across switch-preserving signal integrity in precision analog-switching and sensor excitation circuits. |
| High noise immunity | VI(off) ≤ −0.5 V and VI(on) ≥ −1.4 V provide >0.9 V hysteresis margin-rejecting ESD transients and crosstalk in noisy industrial I/O modules. |
| Thermal derating support | Rated 450 mW at 25 °C with linear derating to 0 mW at 150 °C junction-enables accurate thermal budgeting in sealed enclosures without forced air. |
Applications
| Industrial PLC Input Modules | USB-C Port Power Switching |

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC114YQC | NPN complement with identical R1/R2 values (10 kΩ/47 kΩ), same package, but opposite polarity and +50 V VCEO. | Suitable for low-side switching only; requires inverted logic drive and cannot replace high-side PNP configurations. | Select when load must be switched to ground and board layout favors NPN topology with shared emitter return. |
| BC857B,215 | Discrete PNP BJT (no integrated resistors); hFE = 200–450; requires two external bias resistors; SOT23-3 package (larger, no SWF). | Offers higher gain and wider VCEO (−45 V), but increases component count, layout area, and AOI inspection complexity. | Choose only if design requires adjustable bias or higher current gain beyond 100, and space/inspection constraints are secondary. |
Compared with PDTC114YQC, PDTA114YQC enables true high-side switching with logic-compatible input thresholds; versus BC857B, it trades gain adjustability for BOM reduction, smaller footprint, and guaranteed bias stability-making it optimal for volume production of compact digital interfaces.

FAQ
What is the maximum continuous collector current for PDTA114YQC?
The PDTA114YQC is rated for −100 mA continuous collector current (IO) at Tamb ≤ 25 °C on a standard FR4 PCB with 70 µm copper. Derating applies above 25 °C: power dissipation drops linearly to 0 mW at 150 °C junction temperature, supporting sustained operation up to −70 mA at 75 °C ambient.
Can PDTA114YQC replace BC857B in existing designs without layout changes?
No-PDTA114YQC uses a DFN1412D-3 (SOT8009) 1.4 × 1.2 mm package with side-wettable flanks, while BC857B uses SOT23-3 (3.0 × 1.4 mm). Footprint, solder stencil, and reflow profile differ significantly. A redesign is required to accommodate the smaller, leadless package and leverage its integrated biasing benefits.
What is the purpose of the side-wettable flanks on the DFN1412D-3 package?
Side-wettable flanks expose vertical copper surfaces on all three terminals, allowing automated optical inspection (AOI) systems to verify solder fillet formation and wetting quality-critical for detecting head-in-pillow defects and insufficient solder in high-reliability manufacturing. This feature is not present in standard DFN packages.
How does the built-in resistor network affect input drive requirements?
The integrated 10 kΩ (R1) and 47 kΩ (R2) resistors set a fixed base current path: applying −1.0 V to Pin 1 draws ~0.1 mA into R1, yielding ~0.25 mA effective base drive. This eliminates external resistor selection, ensures consistent switching thresholds across temperature, and allows direct connection to 3.3 V/5 V GPIOs without additional logic-level translation.
