Product details
Overview
PDTA143XE from Nexperia is a PNP resistor-equipped transistor (RET) in SOT416 (SC-75) surface-mount package, designed for digital switching applications with built-in bias resistors R1 = 4.7 kΩ and R2 = 10 kΩ, −50 V VCEO, −100 mA IO, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTA143XE datasheet, PDTA143XE pinout, PDTA143XE application, or PDTA143XE equivalent, key selection considerations include its integrated base resistors, ultra-small footprint, guaranteed −100 mA output current capability, and suitability as a cost-saving alternative to BC847/857 series in digital control circuits.
Technical Context
The PDTA143XE integrates a PNP bipolar transistor with two monolithically embedded silicon resistors: R1 (input bias resistor, 4.7 kΩ typ.) connected between base and input terminal, and R2 (base-emitter feedback resistor, 10 kΩ typ.) connected between base and emitter. This configuration eliminates external bias components and enables direct logic-level drive.
It operates as a single-polarity digital switch with defined on/off thresholds: VI(on) = −1.5 V (typ.) at IC = −20 mA and VI(off) = −0.9 V (typ.) at IC = −100 μA, ensuring robust noise immunity in automotive and industrial control environments.
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 - Guaranteed continuous output current; sufficient for driving LED indicators, small relays, or logic inputs. |
| R1 | 4.7 kΩ (3.3–6.1 kΩ) - Input bias resistor value; sets base current for predictable saturation under standard logic drive. |
| R2/R1 | 2.1 (1.7–2.6) - Feedback resistor ratio; ensures stable turn-off and prevents unintended conduction due to leakage. |
| VCE(sat) | −100 mV (max) at IC = −10 mA, IB = −0.5 mA - Low saturation voltage minimizes power loss and heating in high-duty-cycle switching. |
| hFE | 50 (min) at VCE = −5 V, IC = −10 mA - DC current gain ensures reliable saturation with minimal base drive overhead. |
| fT | 180 MHz (typ.) - Transition frequency of internal transistor; supports fast edge response in digital signal routing up to ~10 MHz. |
Pinout & Package
SOT416 (SC-75) ultra-small plastic surface-mounted package, 3-lead, body dimensions 1.45 × 0.9 × 0.7 mm (L × W × H), optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level input (e.g., MCU GPIO); no external pull-up required. |
| 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 to ground when active. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Eliminates need for two external resistors, reducing BOM count and layout area by ≥2 components per switch. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock per AEC standard. |
| Ultra-small SOT416 footprint | 0.9 mm width enables placement in space-constrained modules such as infotainment control boards or sensor nodes. |
| −100 mA output rating | Supports direct drive of typical automotive indicator LEDs (20 mA), small solenoids (≤50 mA), or CMOS/TTL inputs without buffer stages. |
| Low VCE(sat) | ≤−100 mV ensures <1 mW conduction loss at 10 mA, critical for thermally limited modules and battery-powered systems. |
Applications
| Automotive Interior Lighting Control | Industrial Digital Input Conditioning |
|---|---|
Use Scenario: Switching 12 V LED strips in door panels or dashboard backlighting using 3.3 V microcontroller outputs. IC Role / Device Role / Timing Role: PNP RET acts as a level-shifting, current-sinking switch enabling low-voltage logic to control higher-voltage loads.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC143XE | NPN complement with identical R1/R2 values and SOT416 package; requires inverted logic drive and low-side switching topology. | Used where load must be switched to ground instead of supply rail; not interchangeable without circuit redesign. | Select PDTC143XE only when NPN configuration aligns with existing board layout and control architecture. |
| BC857B,115 | Discrete PNP transistor without integrated resistors; requires external R1/R2; higher hFE (200–450) but no guaranteed VI(on)/VI(off) thresholds. | Suitable for analog amplification or precision biasing; lacks built-in noise immunity and standardized switching behavior. | Choose BC857B,115 only when design requires adjustable bias or higher gain, accepting added component count and layout complexity. |
Compared with PDTC143XE, the PDTA143XE provides high-side switching with native logic compatibility, while BC857B,115 offers greater flexibility at the cost of design effort and reduced noise margin-making PDTA143XE optimal for volume automotive and industrial digital control where predictability and miniaturization are prioritized.

FAQ
What is the maximum operating temperature for PDTA143XE?
The PDTA143XE 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 830 K/W in free air on FR4 PCB, meaning it can sustain full −100 mA load only at low ambient temperatures unless heatsinking or airflow is applied. Derating curves in the datasheet confirm safe operation up to +125 °C ambient at reduced current.
Is PDTA143XE pin-compatible with other SOT416 transistors like BC847?
No, PDTA143XE is not pin-compatible with BC847 series devices. While both use SOT416, BC847 is a discrete NPN transistor with emitter-collector-base pinout (1=E, 2=C, 3=B), whereas PDTA143XE is a PNP RET with input-GND-output pinout (1=IN, 2=GND, 3=OUT). Swapping them would cause functional failure and potential damage due to reversed polarity and internal resistor connections.
Does PDTA143XE require external base resistors?
No, PDTA143XE does not require external base resistors. It integrates R1 = 4.7 kΩ (input-to-base) and R2 = 10 kΩ (base-to-emitter) internally. These resistors enable direct connection to standard logic outputs (e.g., 3.3 V or 5 V MCU GPIO) without additional components-reducing bill-of-materials count and PCB area while ensuring consistent turn-on/turn-off behavior.
Can PDTA143XE be used in high-frequency switching applications?
The PDTA143XE's internal transistor has a typical fT of 180 MHz, but its switching speed is limited by RC time constants of the integrated resistors and package parasitics. It is characterized for digital switching up to ~10 MHz in typical applications. For >1 MHz PWM or high-speed data routing, verify rise/fall times (tr/tf) from the datasheet's transient characteristics and ensure layout minimizes stray capacitance at pin 3 (collector).
What marking code identifies PDTA143XE on the package?
The PDTA143XE is marked with the code "35" on its top surface. This 2-character laser marking is standardized per Nexperia's ordering information table and distinguishes it from other variants in the PDTA143X family (e.g., PDTA143XM is marked "DN", PDTA143XT is marked "*31"). The marking appears adjacent to the cathode band or orientation notch on the SOT416 body.
