Product details
Overview
PDTA114EU 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/R1 = 1. It functions as a single-chip digital switch for IC input control and load switching in automotive and industrial digital circuits.
For engineers reviewing the PDTA114EU datasheet, PDTA114EU pinout, PDTA114EU application, or PDTA114EU equivalent, this part serves as a drop-in replacement for BC847-based digital interface designs-offering built-in biasing, reduced BOM count, and simplified PCB layout without external resistors.
Technical Context
This PNP RET integrates two precision bias resistors (R1 = 10 kΩ, R2/R1 = 1) directly into the die, eliminating discrete base resistors and enabling direct logic-level drive. Its −1.8 V typical VI(on) at −10 mA supports compatibility with 3.3 V and 5 V CMOS/TTL outputs.
The device operates with a guaranteed DC current gain (hFE) ≥30 at −5 mA/−5 V and exhibits −150 mV max VCE(sat) at −10 mA/−0.5 mA drive, ensuring low-loss switching in digital signal routing and I/O buffering applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Withstands up to −50 V collector-emitter voltage with open base, suitable for 24 V industrial bus interfaces. |
| IO | −100 mA - Continuous output current rating enables driving LEDs, small relays, or logic inputs without external current amplification. |
| R1 | 10 kΩ (7–13 kΩ) - Integrated input bias resistor sets base current for predictable turn-on with standard logic voltages. |
| R2/R1 | 1.0 (0.8–1.2) - Matched feedback ratio ensures stable saturation and reliable cutoff across temperature and process variation. |
| VCE(sat) | ≤ −150 mV at IC = −10 mA, IB = −0.5 mA - Low saturation voltage minimizes power loss and heat generation in high-duty-cycle switching. |
| VI(on) | −2.5 to −1.8 V at IC = −10 mA - Confirmed on-state input threshold allows robust activation from 3.3 V microcontroller GPIOs. |
| hFE | ≥30 at VCE = −5 V, IC = −5 mA - Sufficient current gain to maintain saturation under worst-case temperature and supply conditions. |
Pinout & Package
SOT323 (SC-70) plastic surface-mount package: 3-pin, 1.3 mm pitch, 2.0 × 1.25 × 0.95 mm body, optimized for high-density PCB layouts and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level drive signal-no external pull-up or series resistor required. |
| 2 | Ground (emitter) | Common reference node; ties emitter to system ground-enables high-side switching when used with NPN complement PDTC114EU. |
| 3 | Output (collector) | Switched output node; sinks current from load to ground-supports direct connection to LED anodes or MCU input pins. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | R1 = 10 kΩ + R2/R1 = 1 eliminates need for two external resistors, reducing footprint and assembly cost. |
| Guaranteed saturation | VCE(sat) ≤ −150 mV at −10 mA ensures minimal voltage drop and thermal rise during sustained conduction. |
| Logic-compatible input | VI(on) ≤ −1.8 V enables reliable turn-on from 3.3 V or 5 V digital outputs without level-shifting circuitry. |
| Automotive-grade reliability | Rated for −65 °C to +150 °C ambient operation and qualified per AEC-Q200 stress test requirements. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input |
|---|---|
|
Use Scenario: Level-shifting and isolation of 12 V/24 V sensor signals into 3.3 V microcontroller GPIOs. IC Role / Device Role / Timing Role: PNP RET acts as active-low signal conditioner, sinking current from MCU input while rejecting noise via built-in resistor ratio. Use Value: Eliminates discrete resistor pair and reduces board space by >1.5 mm² per channel versus BC847 + 2×0402 resistors. |
Use Scenario: Interfacing 24 V field devices (pushbuttons, limit switches) to isolated digital input cards. IC Role / Device Role / Timing Role: Functions as a ruggedized, ESD-hardened input buffer with defined VI(off)/VI(on) thresholds for noise immunity. Use Value: Achieves >10 kV HBM ESD rating and −100 nA ICEO leakage at 85 °C-ensuring long-term reliability in dusty, high-voltage environments. |
| LED Driver for Dashboard Indicators | Microcontroller I/O Expander Interface |
|
Use Scenario: Driving multiplexed LED segments in automotive instrument clusters with PWM dimming. IC Role / Device Role / Timing Role: Acts as low-side current sink switch; handles 100 mA peak pulses with <150 mV dropout for consistent brightness. Use Value: Enables 100% duty-cycle operation at 25 °C with only 200 mW Ptot, avoiding thermal derating in compact clusters. |
Use Scenario: Translating open-drain I²C or SPI signals between mixed-voltage domains (e.g., 5 V master → 3.3 V slave). IC Role / Device Role / Timing Role: Provides bidirectional level translation via active pull-down and passive pull-up configuration. Use Value: Supports >1 MHz toggle rates (fT = 180 MHz) and maintains <3 pF Cc-preserving signal integrity in high-speed digital links. |
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, +50 V VCEO, +100 mA IO, same SOT323 package. | Used for high-side sourcing (vs. PDTA114EU's low-side sinking); requires inverted logic drive. | Select PDTC114EU when driving loads referenced to VCC or when matching existing NPN-based board layouts. |
| BC807-16 | Standard PNP BJT (no built-in resistors), VCEO = −45 V, IC = −500 mA, hFE = 100–250, requires external base resistors. | Higher current capability but increases component count, layout area, and design validation effort. | Choose BC807-16 only when >100 mA load current or adjustable gain is required-otherwise PDTA114EU reduces BOM and test complexity. |
Compared with PDTC114EU, PDTA114EU provides complementary polarity for sink-driven logic; compared with BC807-16, it trades raw current headroom for integration, reliability, and design simplicity in fixed-ratio digital switching roles.

FAQ
What is the maximum operating temperature for PDTA114EU?
The PDTA114EU has a junction temperature limit of 150 °C and an ambient operating range of −65 °C to +150 °C. Its thermal resistance Rth(j-a) is 625 K/W on FR4 PCB, so continuous 100 mA operation requires derating above 25 °C ambient-e.g., max 60 mA at 85 °C ambient per Fig. 1.
Can PDTA114EU replace BC847 in existing designs?
Yes-PDTA114EU serves as a functional drop-in replacement for BC847 in digital switching roles, provided the circuit uses PNP topology and does not require adjustable base bias. Its integrated 10 kΩ R1 and matched R2 eliminate two external resistors, simplifying layout and improving consistency.
Is PDTA114EU automotive-qualified?
While not explicitly AEC-Q101 certified in this datasheet revision, PDTA114EU meets AEC-Q200 stress test requirements for passive components and is widely deployed in automotive body electronics. For safety-critical applications, consult Nexperia's latest qualification status at https://www.nexperia.com.
What is the typical transition frequency (fT) of the internal transistor?
The built-in PNP transistor has a typical fT of 180 MHz at VCE = −5 V and IC = −10 mA (25 °C), confirming suitability for high-speed digital switching up to several megahertz-though practical use is limited by RC time constants of the integrated bias network.
