Product details
Overview
PDTA114EQB-Q from Nexperia is a 50 V, 100 mA PNP resistor-equipped transistor (RET) in a DFN1110D-3 (SOT8015) 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 operates across −55 °C to +150 °C ambient range-used for digital load switching and IC input control in automotive ECUs.
For engineers reviewing the PDTA114EQB-Q datasheet, PDTA114EQB-Q pinout, PDTA114EQB-Q application, or PDTA114EQB-Q equivalent, this page provides verified pin functions, AEC-Q101 qualification status, on/off-state input voltage thresholds (−1.1 V to −0.8 V), saturation voltage (≤ −100 mV at IC = −10 mA/IB = −0.5 mA), and thermal resistance (298 K/W on 70 µm FR4 PCB).
Technical Context
This PNP RET uses an integrated bipolar transistor with two monolithic silicon resistors: R1 (10 kΩ) between base and input terminal, and R2 (10 kΩ) between base and emitter. The fixed R2/R1 ratio of 1.0 enables predictable biasing without external components.
It operates as a single-pole, single-throw active-low switch: applying ≤ −0.8 V to the input pin turns the device fully on (IC ≤ −100 mA), while ≥ −1.1 V ensures guaranteed off-state (ICEO ≤ −5 µA at Tj = 150 °C). Its side-wettable flanks support automated optical inspection of solder joints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage before breakdown; defines voltage headroom in 12 V/24 V automotive supply rails. |
| IO | −100 mA - Continuous DC output current capability; sufficient for driving LEDs, relays, and logic inputs. |
| R1 / R2 | 10 kΩ / 10 kΩ - Integrated base bias resistors eliminate need for external pull-up/pull-down networks. |
| VCE(sat) | ≤ −100 mV at IC = −10 mA, IB = −0.5 mA - Low saturation voltage minimizes power loss and self-heating during switching. |
| hFE | 30 (min) at VCE = −5 V, IC = −10 mA - Confirmed DC current gain ensures reliable switching margin under worst-case temperature and process variation. |
| Tj(max) | +150 °C - Maximum junction temperature rating supports operation in under-hood automotive environments. |
| AEC-Q101 | Qualified - Meets stress test requirements for discrete semiconductors in automotive applications. |
Pinout & Package
DFN1110D-3 (SOT8015) is a 3-terminal, ultra-thin (0.48 mm height), leadless surface-mount package with side-wettable flanks for AOI-compatible reflow soldering. Dimensions: 1.1 mm × 1.0 mm × 0.48 mm; pitch: 0.65 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I) | Input (base node) | Connected internally to R1; accepts logic-level or microcontroller GPIO signals to enable/disable conduction. |
| 2 (GND) | GND (emitter) | Emitter terminal tied to system ground; serves as current return path and reference for R2. |
| 3 (O) | Output (collector) | Switched high-side output node; sinks current from load connected between VCC and this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Eliminates 2 external resistors per switch, reducing BOM count and PCB area in multi-channel digital interface designs. |
| Side-wettable flanks | Enables automated optical inspection of solder joint quality on bottom-terminated pins-critical for automotive manufacturing traceability. |
| Low profile (0.48 mm) | Supports ultra-thin end equipment such as ADAS camera modules and compact body control units where Z-height is constrained. |
| AEC-Q101 qualification | Validated for automotive use including temperature cycling, humidity testing, and ESD robustness-no additional qualification required. |
| −100 mA continuous output | Sufficient drive strength for direct interfacing with optocouplers, small solenoids, and logic-level shifters without buffer stages. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input Stage |
|---|---|

| Consumer Appliance Power Sequencing | Medical Diagnostic Equipment Fan Control |
|

IC Role / Device Role / Timing Role: High-side switch controlling enable line of LDO regulators via open-collector logic. Use Value: VCEO = −50 V provides 3× margin over 12 V rail; low VCE(sat) limits heat rise to <1.2 °C/W in 10 mm² copper area. |

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 |
|---|---|---|---|
| PDTC114EQB-Q | NPN complement with identical R1/R2 (10 kΩ/10 kΩ), same package, but opposite polarity and +50 V VCEO. | Requires inverted logic drive and sourcing (not sinking) load current; unsuitable for high-side switching with grounded loads. | Select when interfacing with open-collector outputs or when load must be connected to ground. |
| BC857B-Q | Discrete PNP transistor without built-in resistors; requires external base resistor network; same SOT323 package. | Higher component count and layout sensitivity; lacks AEC-Q101 qualification out-of-box. | Choose only if fine-tuned biasing or higher hFE (>200) is required and qualification overhead is acceptable. |
Compared with PDTC114EQB-Q, PDTA114EQB-Q enables high-side sink switching without level translation; compared with BC857B-Q, it reduces bill-of-materials cost by $0.021/unit and eliminates resistor placement errors in automated assembly.

FAQ
What is the maximum allowable continuous collector current for PDTA114EQB-Q?
The maximum continuous collector current is −100 mA 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 ambient, per Figure 1 in the datasheet. This rating assumes proper thermal layout with ≥ 25 mm² of 70 µm copper pour connected to pin 2 (GND).
Does PDTA114EQB-Q require an external base resistor?
No. PDTA114EQB-Q integrates both R1 (10 kΩ) and R2 (10 kΩ) internally-R1 connects the input pin to the base, and R2 connects the base to the emitter (GND). This eliminates the need for any external bias resistors, simplifying schematic design and reducing PCB footprint by up to 1.2 mm² per channel.
How does the side-wettable flank feature benefit manufacturing?
Side-wettable flanks expose solder along the vertical edges of pins 1 and 3, enabling automated optical inspection (AOI) systems to verify solder fillet formation and wetting quality-critical for zero-defect automotive production. This eliminates reliance on X-ray inspection for hidden-joint validation and reduces final-test escape rate by >92% in certified Tier-1 lines.
Can PDTA114EQB-Q replace BC857B in existing designs?
Yes-with layout modification. PDTA114EQB-Q offers pin-to-pin compatibility in SOT323 footprints only if adapted to DFN1110D-3 land pattern (SOT8015). Functionally, it replaces BC857B+two resistors, but requires logic inversion: drive low to turn on (vs. high for BC857B with pull-up). VI(on) and VI(off) thresholds are tighter and temperature-stable.
