Product details
Overview
PDTB114EQAZ from Nexperia is a PNP resistor-equipped transistor (RET) in a DFN1010D-3 (SOT1215) package, designed for digital switching applications with −50 V VCEO, −500 mA IO, and integrated 10 kΩ/10 kΩ bias resistors. It serves as a compact, AEC-Q101-qualified load switch or IC input controller in space-constrained automotive and industrial PCBs.
For engineers reviewing the PDTB114EQAZ datasheet, PDTB114EQAZ pinout, PDTB114EQAZ application, or PDTB114EQAZ equivalent, this device offers verified DC current gain (hFE = 70 min at −50 mA), low −100 mV VCE(sat), and AOI-compatible side-pads - critical for high-reliability digital interface design and component count reduction.
Technical Context
This PNP RET integrates two matched 10 kΩ bias resistors (R1 = R2 = 10 kΩ ±30%) to simplify base drive circuitry and eliminate external components. Its internal transistor delivers hFE ≥70 at −50 mA collector current and −5 V VCE, with VCE(sat) ≤ −100 mV under IC/IB = 20 conditions.
The DFN1010D-3 package features visible, solderable side pads and a 0.37 mm profile, enabling automated optical inspection and thermal performance up to 940 mW on 4-layer FR4 with 1 cm² collector pad. It operates across −55 °C to +150 °C ambient and meets AEC-Q101 stress qualification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage with open base; enables use in 24 V automotive supply rails with margin. |
| IO | −500 mA: Continuous output current capability; supports driving moderate loads like LED strings or small relays. |
| R1 / R2 | 10 kΩ / 10 kΩ: Matched internal bias resistors reduce BOM count and improve consistency vs. discrete resistor + transistor solutions. |
| hFE | ≥70 at −50 mA: Sufficient DC gain for reliable saturation with low base drive current in digital logic interfacing. |
| VCE(sat) | ≤ −100 mV at −50 mA / −2.5 mA: Minimizes conduction loss and self-heating during active switching. |
| Package | DFN1010D-3 (SOT1215): 1.1 × 1.0 × 0.37 mm ultra-thin leadless package with side-wettable flanks for AOI and robust reflow yield. |
Pinout & Package
DFN1010D-3 (SOT1215) is a 3-terminal, leadless surface-mount package with visible side pads for automated optical inspection and enhanced thermal dissipation. Dimensions: 1.1 mm × 1.0 mm × 0.37 mm body height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connects to control signal; internal R1 routes current to base node for turn-on. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; provides return path for load current. |
| 3 & 4 | Output (collector) | Dual-collector terminals (pins 3 and 4) share same node; increase current handling and thermal spreading. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22 standards. |
| ±10% R2/R1 tolerance | Ensures predictable base current ratio and consistent switching thresholds across production lots. |
| 0.37 mm package height | Enables ultra-thin end equipment such as wearables and slim automotive modules without compromising thermal performance. |
| Side-wettable flanks | Supports automated optical inspection of solder joints, improving manufacturing defect detection rate. |
| Reduced component count | Replaces discrete PNP transistor + two bias resistors, lowering PCB area, assembly cost, and test complexity. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input Stage |

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 |
|---|---|---|---|
| PDTB114EQA | Same electrical specs and package; Z suffix denotes tape-and-reel packaging per AEC-Q101 requirements. | No functional difference; identical use in automotive and industrial designs requiring traceable sourcing. | Select PDTB114EQAZ when full AEC-Q101 compliance documentation and lot traceability are required. |
| BC807-40 | Discrete PNP transistor without built-in resistors; requires two external 10 kΩ resistors for equivalent biasing. | Higher BOM count and larger footprint; less suitable for AOI and high-density layouts. | Choose only if legacy design reuse or resistor value customization is mandatory. |
Compared with PDTB114EQA, the Z-suffix variant adds full automotive traceability and packaging compliance; versus BC807-40, it reduces PCB area by >40%, eliminates resistor placement risk, and guarantees R1/R2 matching within ±10%.

FAQ
What is the maximum continuous collector current for PDTB114EQAZ?
The maximum continuous output current (IO) is −500 mA, specified under standard thermal conditions (FR4 PCB, 4-layer copper, 1 cm² collector pad). Derating applies above +25 °C ambient per the power derating curve in the datasheet, with Ptot dropping to 525 mW at +75 °C.
How does the R1/R2 resistor ratio affect switching behavior?
The R2/R1 ratio is tightly controlled at 0.9–1.1 (±10%), ensuring consistent base current division and predictable VI(on)/VI(off) thresholds. This guarantees reliable turn-on at −2.2 V and turn-off below −1.5 V, minimizing ambiguity in digital logic interfacing.
Can PDTB114EQAZ be used in place of BC807-40 without circuit modification?
No direct substitution is possible without redesign: BC807-40 lacks internal resistors and requires external 10 kΩ base resistors. Using PDTB114EQAZ eliminates those resistors but changes the input node impedance and may require adjusting upstream drive strength to maintain VI(on) compliance.
Is the DFN1010D-3 package compatible with standard reflow profiles?
Yes - the DFN1010D-3 package is qualified for standard lead-free reflow (J-STD-020), with peak temperature up to 260 °C. The side-wettable flanks and thermal characteristics (Rth(j-sp) = 40 K/W) support high-yield soldering using recommended footprint dimensions from Figure 34 of the datasheet.
