Product details
Overview
PDTA143EU,115 from Nexperia is a PNP resistor-equipped transistor (RET) in SOT323 (SC-70) surface-mount package, designed for digital switching applications with built-in bias resistors R1 = 4.7 kΩ and R2 = 4.7 kΩ, −50 V VCEO rating, −100 mA output current capability, and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTA143EU,115 datasheet, PDTA143EU,115 pinout, PDTA143EU,115 application, or PDTA143EU,115 equivalent, key selection criteria include its integrated base resistors, thermal resistance of 625 K/W, off-state input voltage of −1.1 V (typ), on-state input voltage of −1.9 V (typ), and suitability as a cost-saving alternative to BC857-series transistors in space-constrained digital control circuits.
Technical Context
This PNP RET integrates two precision bias resistors (R1 = 4.7 kΩ, R2/R1 = 1.0 typ) directly into the die, eliminating external base resistors and reducing PCB footprint. Its internal transistor exhibits hFE ≥30 at IC = −10 mA and VCE = −5 V, with fT = 180 MHz (typ) enabling stable operation in high-speed digital switching up to ~10 MHz edge rates.
The device operates across −65 °C to +150 °C ambient, with VI(off) ≤ −0.5 V and VI(on) ≥ −2.5 V defining robust logic-level compatibility. Thermal derating begins at Tamb > 25 °C, with Ptot = 200 mW at 25 °C and full derating to zero at 150 °C per the 625 K/W Rth(j-a) value.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage under open-base conditions; supports 24 V automotive rail switching with margin. |
| IO | −100 mA - Continuous DC output current capability; sufficient for driving LED indicators, small relays, or logic inputs. |
| R1 | 4.7 kΩ (typ) - Integrated input bias resistor; enables direct connection to 3.3 V/5 V logic without external components. |
| VI(on) | −1.9 V (typ) - Minimum base input voltage required to saturate the transistor; ensures reliable turn-on with standard CMOS/TTL outputs. |
| VCEsat | −150 mV (max) - Collector-emitter saturation voltage at IC = −10 mA / IB = −0.5 mA; minimizes power loss and heating during conduction. |
| Rth(j-a) | 625 K/W - Junction-to-ambient thermal resistance on FR4 PCB; determines temperature rise under load (e.g., +125 °C rise at 200 mW). |
| fT | 180 MHz (typ) - Transition frequency of the internal transistor; supports fast digital switching with <5 ns propagation delay in typical configurations. |
Pinout & Package
PDTA143EU,115 is housed in a SOT323 (SC-70) plastic surface-mounted package measuring 2.2 mm × 1.35 mm × 1.15 mm, optimized for high-density PCB layouts and reflow soldering only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1 and R2; accepts logic-level drive signal; no external base resistor needed. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference for input and output paths. |
| 3 | Output (collector) | Switched output node; sinks current from load connected between VCC and pin 3; compatible with open-collector logic interfaces. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | R1 = 4.7 kΩ, R2 = 4.7 kΩ - Eliminates two external resistors, reducing BOM count and placement cost in digital interface circuits. |
| AEC-Q101 qualification | Qualified for automotive applications - Validated for temperature cycling, humidity, and mechanical stress per AEC standard; suitable for engine control, body electronics, and ADAS modules. |
| Ultra-small footprint | SOT323 package (2.2 × 1.35 mm) - Enables routing in tight spaces such as portable infotainment units and compact sensor nodes. |
| Low VI(off) | −1.1 V (typ) - Ensures firm cutoff when driven by low-voltage logic (e.g., 1.8 V I/O), preventing leakage-induced false triggering. |
| High-speed switching | fT = 180 MHz (typ) - Supports clean digital edges in microcontroller GPIO expansion, level translation, and pulse-width modulation (PWM) dimming circuits. |
Applications
| Automotive Body Control Module | Industrial PLC Input Interface |
|---|---|
Use Scenario: Switching 12 V indicator LEDs and solenoid drivers in door module PCBs. IC Role / Device Role / Timing Role: PNP RET acts as a grounded-emitter high-side switch controlled by MCU GPIO. Use Value: Built-in R1/R2 eliminates discrete resistor placement, reducing assembly cost and improving reliability over temperature in under-hood environments. |

IC Role / Device Role / Timing Role: Load switch controlling VDD supply to peripheral ICs during sleep/wake cycles. Use Value: −150 mV VCEsat minimizes dropout voltage, preserving battery life; SOT323 footprint saves critical board area. |
Use Scenario: Isolating patient-connected analog front-end circuitry from digital control logic in portable monitors.

Equivalent & Alternatives
The following parts are listed as comparable options for similar PNP digital switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC143EU,115 | NPN complement with identical R1/R2 values, SOT323 package, and matching thermal specs. | Requires inverted logic drive and sourcing (not sinking) load current; used where active-high control is preferred. | Select when circuit topology demands NPN configuration or when pairing with PDTA143EU in complementary driver stages. |
| BC857BW,115 | Standard PNP BJT without integrated resistors; requires external R1/R2; same SOT323 package and −50 V/−100 mA ratings. | Higher component count and layout complexity; less immune to ESD-induced latch-up due to lack of built-in base protection. | Choose only if precise bias tuning is required or legacy designs mandate discrete resistor networks for calibration. |
Compared with PDTC143EU,115, PDTA143EU,115 provides native PNP logic-level switching with lower design overhead; versus BC857BW,115, it reduces bill-of-materials and improves production yield but trades off fine bias adjustability.

FAQ
What is the maximum allowable continuous power dissipation for PDTA143EU,115 at 70 °C ambient?
At Tamb = 70 °C, PDTA143EU,115 has a derated Ptot of 120 mW, calculated using its 625 K/W thermal resistance and 150 °C max junction temperature. This allows sustained −60 mA output current at −2 V VCEsat without exceeding Tj limit, verified per Figure 1 power derating curve.
Can PDTA143EU,115 be used with 1.8 V logic controllers?
Yes - its VI(on) = −1.9 V (typ) and VI(off) = −1.1 V (typ) ensure reliable turn-on and turn-off when driven by 1.8 V CMOS outputs with appropriate pull-up/pull-down context. The integrated R1/R2 network maintains stable biasing even at reduced VCC, confirmed in Table 8 characteristics.
Is wave soldering recommended for PDTA143EU,115?
No - Nexperia explicitly states reflow soldering is the only recommended method. Wave soldering is not qualified for this device; thermal stress from wave profiles risks delamination or parametric shift, as noted in Section 11 and Figure 21 footprint notes.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 1.0 (typ) sets the internal feedback path to stabilize base current and improve saturation consistency across temperature. This ratio ensures predictable hFE-dependent gain control and reduces sensitivity to transistor β variation, as characterized in Figure 6 and Table 8.
