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 = R2 = 10 kΩ. It replaces discrete base-resistor transistor configurations in load switching, IC input control, and automotive/industrial digital logic interfaces.
For engineers reviewing the PDTA114EU datasheet, PDTA114EU pinout, PDTA114EU application, or PDTA114EU equivalent, this part serves as a drop-in cost-optimized alternative to BC847-based driver stages-offering simplified layout, reduced BOM count, and guaranteed bias ratio stability across temperature.
Technical Context
The PDTA114EU integrates a PNP bipolar transistor with two monolithically embedded silicon resistors: R1 (base-input resistor) and R2 (base-emitter feedback resistor), forming a single-input, grounded-emitter switch topology. Its fixed R2/R1 ratio of 1.0 ±0.2 ensures consistent turn-on threshold and saturation behavior.
It operates with VI(on) = −2.5 to −1.8 V at IC = −10 mA and achieves VCE(sat) ≤ −150 mV under same conditions. The device supports ambient temperatures from −65 °C to +150 °C and delivers fT = 180 MHz for the internal transistor core.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum collector-emitter voltage before breakdown; enables use in 36 V automotive supply rails with margin. |
| IO | −100 mA - Continuous output current rating; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 10 kΩ (7–13 kΩ range) - Input bias resistor sets base current; eliminates external component in standard TTL/CMOS interface designs. |
| R2/R1 | 1.0 ±0.2 - Fixed feedback ratio stabilizes DC operating point and improves noise immunity vs. discrete resistor networks. |
| VCE(sat) | ≤ −150 mV @ IC = −10 mA, IB = −0.5 mA - Low saturation voltage minimizes power loss and heating in high-duty-cycle switching. |
| hFE | ≥30 @ VCE = −5 V, IC = −5 mA - Guaranteed minimum current gain ensures reliable switching even at elevated junction temperatures. |
| fT | 180 MHz - Transition frequency of internal transistor; supports fast edge rates in digital signal routing up to ~10 MHz. |
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 height. Optimized for reflow soldering on FR4 PCBs with standard footprint per Figure 11.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Single logic-level input node connected internally to R1; accepts −0.8 V to −2.5 V for reliable on/off control. |
| 2 | GND (emitter) | Emitter tied directly to ground reference; provides common return path and simplifies PCB routing. |
| 3 | Output (collector) | Switched high-side output node; sinks current from load connected between VCC and pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic R1 = 10 kΩ and R2 = 10 kΩ eliminate two external resistors and reduce placement error risk. |
| Guaranteed R2/R1 matching | Ratio tolerance ±20% ensures predictable VI(on)/VI(off) thresholds across production lots and temperature. |
| Low thermal resistance | Rth(j-a) = 625 K/W on FR4 PCB enables operation up to 125 °C ambient without derating at 50 mA load. |
| Automotive-grade reliability | Qualified per AEC-Q200 stress tests; suitable for non-safety-critical automotive modules including body control units. |

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 |
|---|---|---|---|
| PDTC114EU | NPN complement with identical R1/R2 values and package; VCEO = +50 V, IO = +100 mA. | Used where active-low sourcing (vs. active-high sinking) is required; incompatible with high-side switching topologies. | Select when interfacing with open-drain outputs or when load must be connected to ground side. |
| BC847B | Discrete NPN transistor without integrated resistors; requires two external bias resistors; hFE = 200–450 (higher gain but uncontrolled bias). | Offers higher current gain and wider VCEO margin (+45 V), but increases BOM count and layout sensitivity to parasitic coupling. | Prefer only when precise analog amplification or variable bias tuning is needed; not recommended for digital switching cost optimization. |
Compared with PDTC114EU, PDTA114EU provides complementary high-side switching capability with matched thermal and electrical specs; versus BC847B, it trades gain flexibility for BOM reduction, layout simplicity, and guaranteed bias stability-critical for volume-manufactured digital interfaces.

FAQ
What is the maximum continuous current the PDTA114EU can switch reliably?
The PDTA114EU is rated for −100 mA continuous output current (IO) at Tamb ≤ 25 °C. Derating applies above 25 °C per the power curve in Figure 1: at 85 °C ambient, maximum sustainable current drops to approximately −60 mA due to Ptot = 200 mW limit and Rth(j-a) = 625 K/W thermal resistance on FR4 PCB.
Can PDTA114EU be used in place of a standard PNP transistor like BC807 without redesign?
No-PDTA114EU has a fixed three-terminal configuration (input, ground, output) with internal resistors, unlike BC807's bare-base-emitter-collector structure. Direct substitution requires removing external base resistors and verifying logic polarity compatibility, as PDTA114EU sinks current from VCC to ground rather than sourcing it.
Does PDTA114EU meet automotive qualification standards?
The PDTA114EU is not AEC-Q100 qualified, but it is AEC-Q200 qualified as a passive component (resistor-equipped transistor). It is approved for non-safety-critical automotive applications such as interior lighting, HVAC controls, and infotainment peripherals-provided system-level validation confirms compliance with ISO 16750 environmental stress requirements.
How does the R2/R1 ratio affect switching performance?
The R2/R1 ratio of 1.0 ±0.2 determines the internal feedback level that stabilizes the base-emitter voltage during conduction. A ratio near unity ensures VI(on) remains tightly bounded between −2.5 V and −1.8 V, reducing sensitivity to supply ripple and improving noise margin in noisy industrial environments.
