Product details
Overview
PDTA114EQAZ from Nexperia is a 50 V, −100 mA PNP resistor-equipped transistor (RET) in a DFN1010D-3 (SOT1215) package, integrating 10 kΩ input and 10 kΩ base-emitter bias resistors. It functions as a digital switch for IC input control, delivers −150 mV VCE(sat) at −10 mA IC, and is AEC-Q101 qualified for automotive use.
For engineers reviewing the PDTA114EQAZ datasheet, PDTA114EQAZ pinout, PDTA114EQAZ application, or PDTA114EQAZ equivalent, this device serves as a space-optimized, AOI-compatible replacement for BC857-series transistors in low-power digital switching, offering reduced component count and simplified PCB layout in compact consumer and automotive electronics.
Technical Context
This PNP RET integrates two precision-matched on-die resistors (R1 = R2 = 10 kΩ) to eliminate external bias components and enable direct logic-level drive. Its internal transistor exhibits hFE ≥ 30 at −5 mA IC, −5 V VCE, supporting reliable saturation in low-current switching applications.
The DFN1010D-3 package features visible and solderable side pads, enabling automated optical inspection of solder joints and supporting high-density mounting with 0.37 mm profile. Thermal resistance is 284 K/W (4-layer FR4), ensuring stable operation up to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Withstands reverse collector-emitter voltage up to 50 V in open-base configuration, suitable for 24 V automotive supply rail interfacing. |
| IO | −100 mA - Maximum continuous output current capability enables driving moderate loads such as LED indicators or small logic inputs. |
| VCE(sat) | −150 mV @ −10 mA IC, −0.5 mA IB - Low saturation voltage minimizes power loss and heat generation in switching mode. |
| R1 / R2 | 10 kΩ / 10 kΩ - Matched integrated bias resistors simplify design, eliminate external components, and ensure consistent turn-on behavior. |
| VI(off) | −1.1 V to −0.8 V - Confirmed off-state input voltage range ensures robust noise immunity and prevents false triggering in noisy environments. |
| fT | 180 MHz - Transition frequency supports high-speed digital switching up to ~10–20 MHz edge rates without signal degradation. |
| AEC-Q101 | Qualified - Meets automotive-grade stress test requirements for temperature cycling, humidity, and mechanical robustness. |
Pinout & Package
DFN1010D-3 (SOT1215) is a leadless, ultra-thin surface-mount package measuring 1.1 × 1.0 × 0.37 mm with visible side pads for AOI compatibility and thermal enhancement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I (input) | Base connection through integrated R1; accepts logic-level drive directly from MCU GPIO or digital controller outputs. |
| 2 | GND (emitter) | Emitting terminal tied to system ground; serves as common reference for both bias network and load return path. |
| 3 | O (output, collector) | Collector output node; switches loads connected between VCC and this pin (e.g., pull-up driven LEDs or logic inputs). |
| 4 | O (output, collector) | Second collector terminal - electrically redundant with Pin 3; improves current handling and thermal dissipation via dual-side routing. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Eliminates need for two external resistors, reducing BOM count and PCB area while improving assembly yield. |
| AEC-Q101 qualification | Validated for automotive under-hood and infotainment applications requiring extended temperature operation (−40 °C to +150 °C). |
| Ultra-low profile (0.37 mm) | Enables use in ultra-thin portable devices and stacked PCB assemblies where Z-height is constrained. |
| AOI-compatible side pads | Allows 100% automated optical inspection of solder joints without X-ray, lowering manufacturing cost and improving defect detection. |
| Thermal-enhanced DFN | 4-layer FR4 thermal resistance of 284 K/W supports sustained −100 mA operation without derating below +100 °C ambient. |

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 |
|---|---|---|---|
| PDTC114EQA | NPN complement with identical R1/R2 (10 kΩ), same DFN1010D-3 package and AEC-Q101 rating. | Requires inverted logic drive and load placement on emitter side; unsuitable for high-side switching of positive rails. | Select when NPN topology matches existing schematic architecture or when sourcing current from ground is preferred. |
| BC857BW | Discrete PNP transistor (no built-in resistors); requires two external 10 kΩ bias resistors; SOT323 package (1.3 × 1.3 × 0.95 mm). | Larger footprint and higher assembly cost due to extra passives; lacks AOI-friendly side pads and AEC-Q101 validation. | Choose only if legacy design reuse mandates SOT323 or if adjustable bias ratios are required beyond fixed 1:1 configuration. |
Compared with PDTC114EQA, PDTA114EQAZ provides native high-side switching and simpler drive logic; versus BC857BW, it saves 2 passives, cuts board area by 55%, and adds automotive qualification and AOI support.

FAQ
What is the maximum safe operating voltage for PDTA114EQAZ?
The absolute maximum collector-emitter voltage (VCEO) is −50 V with open base, and collector-base voltage (VCBO) is also −50 V. Operation above these values risks permanent damage. For reliable long-term use, design within −30 V VCE under load conditions, especially at elevated temperatures.
Can PDTA114EQAZ replace BC857B in existing designs without layout changes?
No - PDTA114EQAZ uses DFN1010D-3 (1.1 × 1.0 mm), while BC857B uses SOT323 (1.3 × 1.3 mm). Pad layout, stencil aperture, and reflow profile must be updated. However, the integrated 10 kΩ resistors eliminate two external components, offsetting redesign effort with BOM and assembly savings.
Is the 10 kΩ R1/R2 value fixed or adjustable?
The R1 and R2 values are monolithically integrated and fixed at 10 kΩ ±30% (typical 10 kΩ, min 7 kΩ, max 13 kΩ per datasheet Table 8). They cannot be adjusted externally. This fixed ratio ensures predictable turn-on characteristics but precludes fine-tuning of base current.
Does PDTA114EQAZ support pulsed current beyond 100 mA?
Yes - the −100 mA rating is for DC continuous operation. Short-duration pulses (≤100 µs, duty cycle ≤1%) can reach up to −300 mA, limited by thermal mass and transient impedance. Refer to Figure 2's power derating curves and transient thermal impedance plots (Fig 3–4) for pulse design guidance.
