Product details
Overview
PDTA123JQAZ from Nexperia is a 50 V, −100 mA PNP resistor-equipped transistor (RET) in a DFN1010D-3 (SOT1215) package, integrating 2.2 kΩ input bias resistor (R1) and 47 kΩ feedback resistor (R2). It functions as a digital switch with built-in biasing for direct GPIO-level control, delivers −100 mV VCE(sat) at −5 mA/−0.25 mA, and is AEC-Q101 qualified for automotive body electronics.
For engineers reviewing the PDTA123JQAZ datasheet, PDTA123JQAZ pinout, PDTA123JQAZ application, or PDTA123JQAZ equivalent, this device serves as a space-optimized, solder-joint-inspectable replacement for discrete BJT + resistor networks in low-power digital interface and load switching circuits where board area, assembly cost, and reliability under thermal cycling are critical.
Technical Context
This PNP RET integrates a silicon transistor with two monolithically embedded thin-film resistors: R1 (2.2 kΩ) connects base to input, and R2 (47 kΩ) connects base to emitter to enable self-biasing and stable turn-off. Its −5 V VEBO rating and −180 µA IEBO support robust noise immunity in 3.3 V logic environments.
The device operates with a DC current gain (hFE) of 100 at −5 V VCE and −10 mA IC, achieves −100 mV saturation voltage under defined drive conditions, and maintains functionality across −55 °C to +150 °C ambient, meeting automotive-grade thermal and lifetime requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Withstands reverse collector-emitter voltage up to 50 V in open-base switching configurations. |
| IO | −100 mA - Continuous output current capability supports driving small relays, LEDs, or logic inputs without external current limiting. |
| R1 / R2 | 2.2 kΩ / 47 kΩ - Fixed internal bias network eliminates external resistors, reducing BOM count and PCB footprint by ~2.5 mm². |
| VCE(sat) | −100 mV @ −5 mA IC, −0.25 mA IB - Low saturation voltage minimizes power loss and heat generation in high-duty-cycle switching. |
| VEBO | −5 V - Emitter-base breakdown voltage enables safe operation with 3.3 V microcontroller outputs without clamping diodes. |
| Package | DFN1010D-3 (SOT1215) - 1.1 × 1.0 × 0.37 mm ultra-thin leadless package with side-wettable flanks for AOI-compatible reflow soldering. |

Pinout & Package
DFN1010D-3 (SOT1215) is a 3-terminal, leadless, thermally enhanced ultra-thin plastic package with visible and solderable side pads. Dimensions: 1.1 mm × 1.0 mm × 0.37 mm height; body thickness 0.245–0.275 mm; pad pitch 0.4 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connects to microcontroller GPIO or logic signal; internally tied to R1 (2.2 kΩ) to base node. |

| 3 & 4 | Output (collector) | Dual-collector terminals (pins 3 and 4) share same internal node, doubling current-handling margin and improving thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Eliminates need for two external resistors, reducing layout complexity and enabling 0.65 mm² total footprint (including pads). |

Applications
| Automotive Interior Lighting Control | Industrial Sensor Interface |
|---|---|
|
Use Scenario: Switching 12 V LED strips in door panels and footwells using 3.3 V MCU GPIO. IC Role / Device Role / Timing Role: Acts as level-shifting, current-sinking switch with integrated bias; no external components required for reliable on/off control.

IC Role / Device Role / Timing Role: Functions as a low-leakage, fast-turning-on power gate driven directly by ARM Cortex-M0+ reset signal. Use Value: VI(on) = −0.75 V (typ) ensures clean turn-on at 3.3 V logic levels; −180 µA IEBO prevents false triggering from ESD transients. |
Use Scenario: Interfacing 1.8 V FPGA I/O banks with 3.3 V peripheral sensors in portable ultrasound units. IC Role / Device Role / Timing Role: Serves as unidirectional logic-level translator with defined hFE = 100 for predictable propagation delay (<100 ns). Use Value: Cc = 3 pF and fT = 180 MHz ensure minimal signal distortion and adequate bandwidth for 10 Mbps digital control signals. |
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 |
|---|---|---|---|
| PDTC123JQA | NPN complement with identical R1/R2 values (2.2 kΩ/47 kΩ), same package, but opposite polarity and +100 mA IO. | Requires inverted logic drive and positive-side switching topology; unsuitable for emitter-grounded loads. | Select when sourcing current from VCC is preferred, e.g., driving high-side LED anodes or pull-up networks. |
| BC857B,215 | Discrete PNP BJT (no built-in resistors); requires external 2.2 kΩ/47 kΩ bias network; SOT23-3 package (2.9 × 1.3 × 1.0 mm). | Higher board area (+1.8 mm²), additional placement step, no AOI-friendly side pads, non-AEC-Q101 rated. | Choose only if legacy design reuse or parametric fine-tuning (e.g., custom R1/R2 values) is required; not recommended for new automotive designs. |
Compared with PDTC123JQA, PDTA123JQAZ enables emitter-grounded switching without logic inversion; compared with BC857B,215, it reduces component count by two resistors and cuts PCB area by >60%, while adding AEC-Q101 qualification and AOI support.

FAQ
What is the maximum continuous collector current for PDTA123JQAZ?
The maximum continuous output current (IO) is −100 mA, verified under standard FR4 PCB conditions with 4-layer copper. Derating applies above +25 °C ambient: power dissipation drops linearly to zero at +150 °C junction temperature, with Rth(j-a) = 284 K/W on 4-layer boards.
Can PDTA123JQAZ be used with 1.8 V logic inputs?
No - its VI(on) minimum is −0.75 V (typical) at −5 mA IC, and VI(off) maximum is −0.5 V, meaning reliable turn-on requires ≥2.2 V negative input swing relative to emitter. It is optimized for 3.3 V and 5 V systems, not sub-2.5 V logic families.
How does the dual-collector configuration (pins 3 and 4) affect layout?
Pins 3 and 4 are internally shorted collector terminals; both must be connected to the same net. This doubles copper area for current handling and improves thermal conduction to the PCB, but requires symmetric solder paste deposition and equal trace width to avoid current imbalance during transient events.
Is the marking code "11 00 01" unique to PDTA123JQAZ?
Yes - per Nexperia's binary marking scheme for SOT1215, "11 00 01" uniquely identifies PDTA123JQAZ among the PDTA143X/123J/143Z/114YQA series. The first two bits "11" denote the product family, "00" selects the R1/R2 ratio group, and "01" specifies the 2.2 kΩ/47 kΩ variant.
