Product details
Overview
PDTA143XQAZ from Nexperia is a 50 V, −100 mA PNP resistor-equipped transistor (RET) in a DFN1010D-3 (SOT1215) package, integrating 4.7 kΩ input bias resistor (R1) and 10 kΩ feedback resistor (R2). It functions as a single-chip digital switch for low-power logic-level interfacing, with −100 mV VCE(sat) at −10 mA/−0.5 mA drive and AEC-Q101 qualification for automotive use.
For engineers reviewing the PDTA143XQAZ datasheet, PDTA143XQAZ pinout, PDTA143XQAZ application, or PDTA143XQAZ equivalent, this part serves as a space-optimized, AOI-compatible replacement for BC857-type discrete BJT + resistor networks in digital I/O buffering, microcontroller GPIO load switching, and level translation circuits requiring <100 mA sink capability.
Technical Context
This PNP RET integrates a silicon bipolar transistor with two monolithically embedded thin-film resistors-R1 connected between base and input terminal, R2 between base and emitter-enabling direct TTL/CMOS logic-level drive without external bias components. Its internal topology eliminates base current calculation and reduces PCB footprint by >50% versus discrete solutions.
The device operates with guaranteed −50 V VCEO and −50 V VCBO, supports −7 V VEB0, and delivers hFE ≥50 at −10 mA collector current and −5 V VCE. Thermal resistance is 284 K/W on 4-layer FR4, enabling stable operation up to +150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage under open-base conditions; enables use in 24 V automotive supply rails with margin. |
| IO | −100 mA - Continuous DC output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| VCE(sat) | −100 mV @ −10 mA/−0.5 mA - Low saturation voltage minimizes power loss and heat generation in switching applications. |
| R1 / R2 | 4.7 kΩ / 10 kΩ - Pre-laser-trimmed internal bias network simplifies design and ensures consistent turn-on behavior across temperature. |
| Package | DFN1010D-3 (SOT1215) - 1.1 × 1.0 × 0.37 mm ultra-thin leadless package with solderable side pads for AOI-compatible assembly. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive discrete semiconductors; suitable for under-hood and infotainment modules. |
| fT | 180 MHz - Transition frequency of the embedded transistor; supports fast digital switching up to ~10–20 MHz edge rates. |
Pinout & Package
DFN1010D-3 (SOT1215) is a 3-terminal, leadless surface-mount package with visible and solderable side pads, body dimensions 1.1 × 1.0 × 0.37 mm, and thermal-enhanced construction for improved power dissipation on 4-layer PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (I) | Input (base node) | Logic-level input terminal; connects internally to R1; accepts −30 V to +7 V per absolute max ratings. |
| 2 (GND) | GND (emitter) | Emitter reference terminal; tied to system ground; forms return path for output current. |
| 3 (O) | Output (collector) | Current-sink output terminal; connects to load; rated for −100 mA continuous and −50 V blocking. |
| 4 (O) | Output (collector) | Dual-collector configuration improves current handling and thermal distribution; electrically parallel to Pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic 4.7 kΩ (R1) and 10 kΩ (R2) resistors eliminate external components and reduce BOM count by one transistor + two resistors. |
| Ultra-low profile | 0.37 mm max height enables use in space-constrained portable and automotive modules where Z-height is critical. |
| AOI compatibility | Visible side pads allow automated optical inspection of solder joints-reducing post-reflow defect escapes in high-volume SMT lines. |
| Reduced pick-and-place cost | Single-component placement replaces three-part assembly (transistor + two resistors), lowering placement time and feeder usage. |
| Automotive qualification | AEC-Q101 qualification confirms reliability under temperature cycling, humidity, and mechanical stress required for automotive ECUs. |
Applications
| Microcontroller GPIO Interface | LED Driver Circuit |
|---|---|
|
Use Scenario: Driving 5 V logic outputs from MCU pins with limited sink current capability (e.g., 4 mA). IC Role / Device Role / Timing Role: PNP RET acts as an active-low level shifter and current amplifier, sinking up to −100 mA while maintaining logic compatibility. Use Value: Eliminates need for external base resistor and pull-up; reduces layout area by 60% vs. discrete BC857 + 10 kΩ + 47 kΩ solution. |
Use Scenario: Controlling indicator LEDs in automotive instrument clusters with 12 V supply and PWM dimming. IC Role / Device Role / Timing Role: Acts as a low-loss current sink switch; handles PWM frequencies up to 20 kHz without saturation delay. Use Value: −100 mV VCE(sat) limits power dissipation to <1 mW at 10 mA, enabling direct routing on thin copper layers without heatsinking. |
| Logic-Level Translation | Small Relay Driver |
|
Use Scenario: Interfacing 3.3 V FPGA I/O to 5 V peripheral logic with bidirectional signal conditioning. IC Role / Device Role / Timing Role: Functions as unidirectional level translator in active-low configuration, ensuring clean 0 V / 5 V transitions. Use Value: VI(on) = −1.5 V typical ensures reliable turn-on from 3.3 V logic; VI(off) = −0.6 V prevents false triggering from noise. |
Use Scenario: Driving 5 V, 40 mA coil relays in industrial control panels using 3.3 V microcontroller outputs. IC Role / Device Role / Timing Role: Provides robust current gain and saturation margin to guarantee relay closure across temperature and voltage variation. Use Value: hFE ≥50 at −10 mA ensures >20× overdrive margin; AEC-Q101 rating supports operation in harsh cabinet environments. |
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 |
|---|---|---|---|
| PDTC143XQA | NPN complement with identical R1/R2 values (4.7 kΩ/10 kΩ); VCEO = +50 V, IO = +100 mA. | Requires high-side sourcing instead of low-side sinking; incompatible with existing PNP-based schematics. | Select only when redesigning for NPN logic polarity or sourcing loads. |
| BC857B,115 | Discrete PNP BJT (no integrated resistors); requires external 4.7 kΩ and 10 kΩ bias network; larger SOT23-3 package. | Higher component count and layout area; lacks AOI-friendly side pads and AEC-Q101 certification. | Choose only if legacy compatibility or higher VEB0 (>−7 V) is required. |
Compared with PDTC143XQA, PDTA143XQAZ provides native low-side sink functionality and automotive qualification; compared with BC857B,115, it reduces bill-of-materials, improves manufacturability, and guarantees bias ratio stability across temperature and process variation.

FAQ
What is the maximum allowable input voltage at the I terminal?
The absolute maximum input voltage (VI) for PDTA143XQAZ is −30 V to +7 V, as specified in Table 6. This range accommodates transient spikes in automotive environments and ensures safe operation when driven directly from 3.3 V or 5 V logic families without clamping diodes.
Can PDTA143XQAZ be used in linear amplification mode?
No-PDTA143XQAZ is optimized for digital switching, not analog amplification. Its built-in resistor network fixes bias conditions, and hFE is only specified at −10 mA IC; no small-signal parameters (e.g., gm, rπ) are characterized for linear operation.
How does the dual-collector configuration (Pins 3 and 4) affect PCB layout?
Pins 3 and 4 are internally shorted collector terminals. Layout must connect both pads to the same net-typically the load return path-to distribute current and thermal stress. The symmetric pad arrangement supports balanced solder wetting and reduces thermal gradient-induced warpage.
Is reflow profile different for DFN1010D-3 versus standard SOT23 packages?
Yes-DFN1010D-3 requires tighter thermal control due to its low mass and side-wettable leads. Nexperia recommends peak reflow temperature ≤260 °C with ≤30 s above 220 °C, and full preheat to minimize thermal shock. Footprint dimensions and solder paste volume must follow Figure 32 in the datasheet.
