Product details
Overview
PDTA114EU from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) package, designed for digital switching applications with VCEO = −50 V, IO = −100 mA, and integrated bias resistors R1 = 10 kΩ and R2 = 10 kΩ. It replaces discrete base-resistor transistor configurations in automotive and industrial control circuits where space and BOM count are critical.
For engineers reviewing the PDTA114EU datasheet, PDTA114EU pinout, PDTA114EU application, or PDTA114EU equivalent, this device serves as a drop-in alternative to BC847-based digital switches-offering simplified drive logic, reduced PCB footprint, and guaranteed bias network matching under temperature variation.
Technical Context
This PNP RET integrates two precision silicon resistors (R1 = 10 kΩ ±30%, R2/R1 = 1.0 ±20%) directly into the emitter-grounded transistor die, eliminating external bias components. Its internal structure supports direct TTL/CMOS-level input drive without level-shifting circuitry.
The device operates with guaranteed VI(on) ≤ −1.8 V at IC = −10 mA and VI(off) ≥ −1.1 V at IC = −100 µA, enabling robust noise margin in noisy industrial environments. Thermal resistance Rth(j-a) = 625 K/W on FR4 ensures stable operation up to Tamb = 125 °C at derated power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with safety margin. |
| IO | −100 mA - Continuous output current capability; sufficient for driving LED indicators, small relays, and logic inputs. |
| R1 | 10 kΩ (7–13 kΩ) - Input bias resistor value; sets base current for predictable turn-on with standard logic high levels. |
| R2/R1 | 1.0 (0.8–1.2) - Feedback-to-input resistor ratio; ensures stable saturation and prevents latch-up during transient conditions. |
| VCE(sat) | ≤ −150 mV at IC = −10 mA, IB = −0.5 mA - Low saturation voltage minimizes power loss and heat generation in switching mode. |
| hFE | ≥30 at VCE = −5 V, IC = −5 mA - Minimum DC current gain ensures reliable switching even at elevated temperatures (−40 °C to +100 °C). |
| Ptot | 200 mW at Tamb ≤ 25 °C - Total power dissipation limit on standard FR4 PCB; defines thermal design boundary for continuous operation. |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 3-pin, 1.3 mm pitch, 2.0 mm × 1.25 mm × 0.95 mm body size, optimized for reflow soldering per IPC-7095.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level signals (0 V to −10 V); no external pull-down required. |
| 2 | Ground (emitter) | Common reference node for both bias resistors and transistor emitter; must be tied to system ground plane. |
| 3 | Output (collector) | Switched high-side load connection point; sinks current when active; compatible with open-collector interface standards. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Matched R1/R2 resistors fabricated monolithically with transistor die-ensures consistent turn-on/off thresholds across temperature and process variation. |
| Reduced component count | Eliminates two external resistors per switch channel-reducing BOM line items, PCB area, and assembly cost by ~0.02 USD/unit at volume. |
| Guaranteed saturation | VCE(sat) ≤ −150 mV at rated current confirms deep saturation-prevents partial conduction and thermal runaway in sustained switching. |
| Automotive-grade reliability | Qualified per AEC-Q101; operates over −65 °C to +150 °C ambient; supports under-hood and engine-control module deployments. |
| Standard marking | %03 code (site-dependent prefix + "03") enables automated optical inspection and traceability in high-speed SMT lines. |
Applications
| Automotive Interior Lighting Control | Industrial PLC Digital Output Module |
|---|---|

| Cost-Sensitive Consumer Appliance Interface | Smart Home Sensor Node Power Management |
|
Use Scenario: Enabling/disabling power to auxiliary sensors (e.g., humidity, motion) in HVAC controllers. IC Role / Device Role / Timing Role: Low-quiescent-load enable switch controlled by MCU sleep/wake state. Use Value: R2/R1 = 1.0 ratio provides symmetric input impedance-minimizing leakage-induced wake-up events during deep-sleep modes. |
Use Scenario: Controlling battery-fed peripheral modules (e.g., Zigbee radio, display backlight) in energy-harvesting nodes. IC Role / Device Role / Timing Role: Ultra-low-power load switch with <100 nA ICEO at 150 °C junction temperature. Use Value: ICEO ≤ −5 µA at Tj = 150 °C ensures <1 µA total standby current per channel-extending battery life beyond 5 years in intermittent-use applications. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC114EU | NPN complement with identical R1/R2 values and package; VCEO = +50 V, IO = +100 mA. | Requires inverted logic drive and low-side load placement; unsuitable for high-side switching topologies. | Select when load grounding is fixed and MCU outputs sink current-avoids level-shifting in NPN-compatible systems. |
| BC847B | Discrete PNP transistor only; no built-in resistors; hFE = 200–450; requires external RB and RBE. | Higher gain but uncontrolled bias network-requires layout tuning and suffers from gain spread across batches and temperature. | Choose only when precise analog amplification is needed; not recommended for digital switching due to inconsistent switching thresholds. |
Compared with PDTC114EU, PDTA114EU enables high-side switching without polarity inversion; compared with BC847B, it guarantees matched biasing and reduces layout sensitivity-making it optimal for production-grade digital I/O where test time and yield matter.

FAQ
What is the maximum operating temperature for PDTA114EU in continuous conduction?
The device supports continuous operation up to Tamb = 125 °C when mounted on an FR4 PCB with standard footprint and 35 µm copper, provided power dissipation remains within the derated curve shown in Figure 1. At 125 °C ambient, maximum allowable Ptot drops to approximately 75 mW to maintain Tj ≤ 150 °C.
Can PDTA114EU be used as a linear amplifier?
No-it is not characterized or specified for linear operation. The datasheet provides only digital switching parameters (VCE(sat), VI(on), VI(off)) and DC current gain at one operating point. No fT, noise figure, or linearity data is published, and the internal resistor network prevents stable biasing for analog gain stages.
Is the R1/R2 ratio temperature-stable?
Yes-the resistors are fabricated monolithically with the transistor die using the same process, resulting in matched TC (temperature coefficient) and drift behavior. Measured R2/R1 variation remains within ±20% across −65 °C to +150 °C, ensuring consistent switching thresholds over full industrial and automotive temperature ranges.
Does PDTA114EU require external decoupling when switching inductive loads?
Yes-a flyback diode (e.g., BAS216) must be placed across the load to clamp inductive kickback, as the device has no internal protection. VCEO = −50 V limits safe inductive energy storage; exceeding this rating risks avalanche failure. Layout should minimize loop inductance between collector, load, and diode.
