Product details
Overview
PDTA114EE from NXP Semiconductors is a PNP resistor-equipped transistor (RET) in SOT416 (SC-75) package, designed for digital switching applications with built-in bias resistors R1 = 10 kΩ and R2 = 10 kΩ, −50 V VCEO, −100 mA IO, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTA114EE datasheet, PDTA114EE pinout, PDTA114EE application, or PDTA114EE equivalent, key selection considerations include its integrated base resistors, ultra-small footprint, automotive-grade reliability, and direct replacement suitability for BC857-series discrete PNP transistors in level-shifting and load-switching circuits.
Technical Context
The PDTA114EE integrates a PNP bipolar transistor with two monolithically embedded silicon resistors-R1 (base input resistor) and R2 (base-emitter feedback resistor)-enabling single-resistor drive logic interface without external bias components. Its fixed R2/R1 ratio of 1.0 ±0.2 ensures stable saturation behavior across temperature.
Designed for low-voltage digital control, it operates with VI(on) ≤ −1.8 V at IC = −10 mA and VI(off) ≥ −1.1 V at IC = −100 μA, supporting TTL and CMOS-compatible input thresholds while maintaining guaranteed turn-off under leakage conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive rail switching with margin. |
| IO | −100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 10 kΩ (7–13 kΩ) - Input bias resistor value; sets base current for predictable turn-on with standard microcontroller GPIOs. |
| R2/R1 | 1.0 (0.8–1.2) - Matched feedback ratio; ensures stable saturation and prevents thermal runaway during conduction. |
| 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 guarantees reliable forced-beta operation with integrated resistors. |
| fT | 180 MHz - Transition frequency of internal transistor; enables fast edge response in digital signal paths up to ~10 MHz. |
Pinout & Package
SOT416 (SC-75) is a 3-pin ultra-small surface-mount plastic package measuring 1.45 mm × 0.9 mm × 0.7 mm, optimized for high-density PCB layouts and reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | input (base) | Connected internally to R1; accepts logic-level drive signal directly from MCU or gate output. |
| 2 | GND (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 from load connected between VCC and pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 + R2 bias network | Eliminates two external resistors per switch, reducing BOM count and layout area in multi-channel digital interfaces. |
| AEC-Q101 qualification | Validated for automotive under-hood and cabin applications including engine control modules and body electronics. |
| Ultra-small SOT416 footprint | 0.9 mm × 1.45 mm body size enables placement in space-constrained modules such as ADAS sensors and infotainment controllers. |
| −100 mA continuous output | Supports direct driving of optocouplers, small solenoids, and LED strings without additional amplification stages. |
| VI(on)/VI(off) threshold separation | ≥0.7 V gap between on/off input voltages ensures noise immunity and robust switching in electrically noisy environments. |
Applications
| Automotive Body Control Module | Industrial PLC Digital Output |
|---|---|
Use Scenario: Controlling door lock actuators and interior lighting via microcontroller GPIOs in BCM units.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC114EE | NPN complement with identical R1/R2 values, package, and ratings; polarity reversal required in circuit design. | Used where active-high logic control or sink-type outputs are preferred over source-type configurations. | Select PDTC114EE when interfacing with open-collector drivers or when load must be connected to ground side. |
| BC857B,115 | Discrete PNP transistor without integrated resistors; requires external R1/R2 for biasing; larger SOT23 package. | Offers higher hFE (200–450) and wider VCEO (−45 V), but increases BOM count and layout complexity. | Choose BC857B,115 only if adjustable biasing, higher gain, or legacy compatibility outweighs space and cost benefits of RET integration. |
Compared with PDTC114EE, PDTA114EE provides source-type switching ideal for high-side load control, while BC857B,115 demands external biasing but allows fine-tuned gain and thermal derating flexibility in thermally demanding designs.

FAQ
What is the maximum operating temperature for PDTA114EE?
The PDTA114EE has a junction temperature limit of 150 °C and an ambient temperature range of −65 °C to +150 °C. Its thermal resistance Rth(j-a) is 830 K/W in free air on FR4 PCB, meaning power dissipation must be limited to maintain safe junction temperatures-e.g., ≤150 mW at Tamb = 25 °C. Derating curves in the datasheet guide thermal design for elevated ambient conditions.
Does PDTA114EE require external bias resistors?
No, PDTA114EE does not require external bias resistors. It integrates R1 = 10 kΩ (7–13 kΩ) and R2 = 10 kΩ (R2/R1 = 0.8–1.2) internally, enabling direct connection to logic-level inputs. This eliminates two passive components per channel, reduces PCB area, and improves manufacturing repeatability compared to discrete PNP transistors like BC857.
Is PDTA114EE compatible with reflow soldering processes?
Yes, PDTA114EE is qualified for reflow soldering only-wave soldering is not recommended. The SOT416 package uses standard 4 mm pitch, 8 mm tape-and-reel packaging (ordering code suffix -115), and its footprint complies with JEDEC J-STD-020 moisture sensitivity level 1. Reflow profile must follow NXP's specified temperature ramp rates and peak temperature limits to avoid package damage or solder joint voiding.
How does PDTA114EE compare to BC857 in digital switching applications?
PDTA114EE serves as a cost-saving, space-efficient alternative to BC857-series discrete PNP transistors in digital switching applications. Unlike BC857, PDTA114EE integrates matched bias resistors, eliminating external components and simplifying layout. It matches BC857's −50 V VCEO and −100 mA IO ratings while adding AEC-Q101 qualification and ultra-small SOT416 packaging.
What is the marking code for PDTA114EE on the package?
The marking code for PDTA114EE is "03", laser-etched on the top surface of the SOT416 package. This 2-character identifier is standardized across NXP's RET family and corresponds to the full type number per Table 5 in the datasheet. Marking is visible under 20× magnification and remains legible after standard reflow processing.
