Product details
Overview
PDTA143XU,115 from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) package, designed for digital switching applications with built-in bias resistors R1 = 4.7 kΩ and R2/R1 = 2.1 ratio. It delivers −100 mA output current, −50 V VCEO, and −100 mV VCEsat at IC = −10 mA/IB = −0.5 mA, enabling direct interface with microcontroller GPIOs in automotive and industrial control circuits.
For engineers reviewing the PDTA143XU,115 datasheet, PDTA143XU,115 pinout, PDTA143XU,115 application, or PDTA143XU,115 equivalent, key selection criteria include verified AEC-Q101 qualification, integrated resistor network eliminating external bias components, thermal resistance of 625 K/W, and compatibility with reflow-only assembly processes.
Technical Context
This PNP RET integrates two precision on-chip resistors (R1 = 4.7 kΩ, R2 = 10 kΩ) to form a fixed-current-biased switch, eliminating external base resistors and reducing PCB footprint. Its −50 V collector-emitter breakdown voltage and −100 mA continuous output rating support robust load switching in 5 V and 3.3 V logic domains.
The device operates across −65 °C to +150 °C ambient range with 150 °C maximum junction temperature, and features 3 pF collector capacitance and 180 MHz fT - enabling reliable performance in high-speed digital interface and level-shifting functions without oscillation risk.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage before breakdown; supports 24 V automotive supply rail derating. |
| IO | −100 mA: Continuous DC output current capability; sufficient for driving LEDs, relays, and small solenoids. |
| R1 | 4.7 kΩ ±28%: Input bias resistor value; sets base current for predictable turn-on with standard logic-high voltages. |
| R2/R1 | 2.1: Fixed internal resistor ratio; ensures stable saturation and prevents latch-up under varying temperature. |
| VCEsat | −100 mV max at IC = −10 mA/IB = −0.5 mA: Low saturation voltage minimizes power loss and self-heating during conduction. |
| Ptot | 200 mW at Tamb ≤ 25 °C: Total power dissipation limit; defines maximum usable current at elevated ambient temperatures. |
| Rth(j-a) | 625 K/W: Junction-to-ambient thermal resistance on FR4 PCB; enables thermal design for sustained −60 mA operation at 85 °C ambient. |
Pinout & Package
SOT323 (SC-70) surface-mount plastic package: 3-terminal, very small outline, 2.2 mm × 1.35 mm × 0.95 mm body, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level input to activate PNP switch; requires no external pull-up/down. |
| 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 this pin. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD22-A114. |
| Built-in R1/R2 bias network | Eliminates two external resistors, reducing BOM count, placement cost, and layout area by >30% vs discrete BJT + resistors. |
| Reflow-only soldering | Compatible exclusively with JEDEC J-STD-020-compliant reflow profiles; avoids wave soldering-induced mechanical stress. |
| −100 mA output capability | Supports direct drive of medium-power loads (e.g., 5 V LED strings, small signal relays) without external driver stage. |
| VI(on)/VI(off) thresholds | −1.5 V typical on-state input voltage and −0.9 V off-state threshold ensure clean logic-level interfacing with 3.3 V/5 V MCUs. |

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 |
|---|---|---|---|
| PDTC143XU,115 | NPN complement with identical R1/R2 values, package, and thermal specs; polarity reversal required in circuit layout. | Used where active-low logic control or NPN-compatible load topology (low-side switching) is preferred. | Select when existing design uses NPN RETs or requires sourcing current instead of sinking. |
| BC807-40,215 | Standard PNP BJT without integrated resistors; requires external R1/R2; higher VCEsat (−700 mV typ), lower hFE consistency. | Suitable only when board space allows extra passives and tighter gain tolerance is not required. | Choose only if legacy designs mandate discrete BJT footprint or cost sensitivity outweighs assembly savings. |
Compared with PDTC143XU,115, PDTA143XU,115 offers complementary PNP functionality with identical integration and thermal behavior; versus BC807-40,215, it reduces bill-of-materials count by two resistors and improves saturation voltage by 600 mV, directly lowering power loss in high-duty-cycle applications.

FAQ
What is the maximum operating temperature for PDTA143XU,115?
The PDTA143XU,115 has a maximum junction temperature of 150 °C and an ambient operating range of −65 °C to +150 °C. Its thermal resistance is 625 K/W on FR4 PCB, allowing sustained −60 mA operation at 85 °C ambient without exceeding Tj limit.
Can PDTA143XU,115 be used in place of BC857B?
Yes - PDTA143XU,115 is explicitly positioned as a cost-saving alternative to BC847/857 series in digital applications. It replaces BC857B plus two external bias resistors, offering identical SOT323 footprint, −50 V VCEO, and −100 mA IO, but with integrated R1/R2 and −100 mV VCEsat versus −700 mV for BC857B.
Is wave soldering supported for PDTA143XU,115?
No - reflow soldering is the only recommended method per Nexperia's datasheet. Wave soldering is not qualified and may cause mechanical damage or solder joint reliability issues due to the SOT323 package geometry and internal resistor structure.
What does the marking code *46 indicate on PDTA143XU,115?
The marking code *46 on the top of the SOT323 package identifies the PDTA143XU type; the asterisk denotes the manufacturing site code per Nexperia's internal traceability system, and '46' is the standardized device identifier for this RET variant.
