Product details
Overview
PDTA114EU-QF from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) package, rated for −50 V VCEO, −100 mA output current, with integrated R1 = 10 kΩ and R2 = 10 kΩ bias resistors; used as a digital switch for IC input control and load switching in automotive ECUs and industrial sensor interfaces.
For engineers reviewing the PDTA114EU-QF datasheet, PDTA114EU-QF pinout, PDTA114EU-QF application, or PDTA114EU-QF equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal derating behavior, and direct substitution guidance for BC847-Q series replacements in high-reliability digital switching designs.
Technical Context
This RET integrates a PNP bipolar transistor with two precision on-die resistors: R1 connects base to input, R2 shunts base to emitter, enabling single-resistor drive logic-level interfacing. It operates with guaranteed −50 V collector-emitter breakdown and −100 mA continuous output under ambient temperatures from −65 °C to +150 °C.
The device exhibits typical hFE ≥ 30 at −5 V VCE and −5 mA IC, −150 mV VCE(sat) at −10 mA IC/−0.5 mA IB, and VI(on) = −2.5 V to −1.8 V, supporting robust turn-on across automotive temperature ranges (−40 °C to +125 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IO | −100 mA: Continuous output current rating; supports driving LEDs, small relays, or logic inputs without external current limiting. |
| R1 | 10 kΩ ±30%: Input bias resistor value; sets base current for predictable switching thresholds with standard CMOS/TTL logic outputs. |
| R2/R1 | 1.0 ±20%: Ratio ensures stable saturation and fast turn-off by providing emitter-base shunt path; eliminates need for external pull-down. |
| VCE(sat) | −150 mV max at −10 mA/−0.5 mA: Low saturation voltage minimizes power loss and heat generation in high-duty-cycle switching. |
| hFE | ≥30 at −5 V, −5 mA: DC current gain sufficient for reliable digital on/off operation without gain-dependent timing variation. |
| Tj max | +150 °C: Maximum junction temperature; validated for under-hood automotive environments per AEC-Q101 stress testing. |
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, FR4 PCB compatible with reflow and wave soldering footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level signals directly-no external base resistor required. |
| 2 | Ground (emitter) | Emitter terminal tied to system ground; serves as common reference for input and output paths. |
| 3 | Output (collector) | Switched high-side output node; sinks current when active, suitable for low-side load switching configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | R1 = 10 kΩ + R2 = 10 kΩ eliminates discrete resistors, reducing BOM count and PCB area by ≥2 components per switch node. |
| AEC-Q101 qualification | Qualified for automotive applications including engine control, body electronics, and ADAS sensors per stress test requirements. |
| Low VCE(sat) | ≤ −150 mV ensures <15 mW conduction loss at 100 mA, critical for thermally constrained modules and extended-life reliability. |
| Wide operating temperature | −65 °C to +150 °C ambient range supports deployment in under-hood, battery management, and industrial motor control systems. |
| SC-70 footprint compatibility | Standardized 2.0 mm × 1.25 mm outline enables drop-in replacement of PDTC114EU (NPN complement) and BC847-Q variants. |
Applications
| Automotive Body Control Module | Industrial Sensor Interface |
|---|---|
Use Scenario: Switching 12 V indicator LEDs and solenoid drivers in door modules and lighting controllers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847B-Q | Discrete PNP BJT without integrated resistors; requires external RB for biasing. | Higher BOM count and layout complexity; less suitable for space-constrained automotive modules. | Select when fine-tuned base current control or higher hFE variability tolerance is needed. |
| PDTC114EU | NPN complement with identical R1/R2 values and SOT323 package; opposite polarity switching behavior. | Used where active-high (source) switching is preferred instead of active-low (sink) configuration. | Select for complementary NPN functionality in dual-rail or push-pull output stages. |
Compared with BC847B-Q and PDTC114EU, PDTA114EU-QF offers plug-and-play digital switching with zero external bias components, reduced PCB area, and guaranteed AEC-Q101 qualification-making it optimal for high-volume automotive and industrial control nodes where reliability and assembly efficiency are prioritized.

FAQ
Is PDTA114EU-QF pin-compatible with BC847B-Q?
No-PDTA114EU-QF has three terminals (input, ground, output) in SOT323 with internal resistor topology, whereas BC847B-Q is a standard 3-lead PNP BJT (base, collector, emitter) without integrated resistors. Pin assignments differ: Pin 1 is input (not base), Pin 2 is emitter (ground), Pin 3 is collector (output). Direct physical replacement requires PCB redesign.
What is the maximum allowable input voltage at Pin 1?
The absolute maximum input voltage at Pin 1 (I) is −40 V to +10 V, per Table 5 limiting values. For reliable operation in digital logic interfaces, VI(on) ranges from −2.5 V to −1.8 V and VI(off) from −1.1 V to −0.8 V at 25 °C, ensuring clean switching with standard 3.3 V or 5 V CMOS outputs.
Does PDTA114EU-QF support PWM switching?
Yes-its −150 mV VCE(sat) and typical fT of 180 MHz (for the internal transistor) enable reliable PWM operation up to several hundred kHz in low-duty-cycle loads like LED dimming or fan speed control, provided thermal limits (Ptot ≤ 200 mW at 25 °C, derated above) are observed.
How does the R2/R1 ratio affect switching performance?
An R2/R1 ratio of 1.0 ±0.2 ensures consistent turn-off behavior by providing a defined base-emitter shunt path, reducing storage time and improving switching speed. This ratio stabilizes the effective βforced during saturation and prevents latch-up in noisy environments-critical for automotive reset and diagnostic circuits.
