Product details
Overview
PDTA143ZQAZ from Nexperia is a 50 V, −100 mA PNP resistor-equipped transistor (RET) in a DFN1010D-3 (SOT1215) package, integrating R1 = 4.7 kΩ and R2 = 47 kΩ bias resistors. It functions as a single-chip digital switch for low-power logic-level interfacing, with −100 mV VCE(sat) at −5 mA/−0.25 mA drive and AEC-Q101 qualification for automotive body electronics.
For engineers reviewing the PDTA143ZQAZ datasheet, PDTA143ZQAZ pinout, PDTA143ZQAZ application, or PDTA143ZQAZ equivalent, this device serves as a space-optimized, AOI-compatible replacement for discrete base-resistor + BJT solutions in 3.3 V/5 V microcontroller I/O buffering, LED load switching, and level translation where compactness and reduced assembly cost are critical.
Technical Context
This PNP RET integrates two precision thin-film resistors (R1 = 4.7 kΩ, R2 = 47 kΩ) directly on-die to form a fixed-current-bias network, eliminating external components while maintaining predictable turn-on/off thresholds. Its −0.6 V to −0.5 V VI(off) ensures robust noise immunity in noisy automotive environments.
The DFN1010D-3 package delivers 0.37 mm profile height and solderable side pads for high-yield reflow, supporting automated optical inspection of solder joints. Thermal resistance is 284 K/W on 4-layer FR4 PCBs, enabling sustained −100 mA operation within junction temperature limits up to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| IO | −100 mA - Sustains continuous switching of medium-current loads like indicator LEDs or small relays. |
| VCE(sat) | −100 mV @ −5 mA/−0.25 mA - Minimizes conduction loss and self-heating in battery-powered systems. |
| R1 / R2 | 4.7 kΩ / 47 kΩ - Sets precise base current ratio for stable digital switching across temperature. |
| VI(on)/VI(off) | −1.3 V / −0.6 V (typ) - Enables clean logic-level recognition with 3.3 V CMOS outputs without pull-up. |
| fT | 180 MHz - Supports fast edge rates in signal routing applications up to ~10 MHz switching. |
| AEC-Q101 | Qualified - Validated for automotive under-hood and cabin modules per stress test requirements. |
Pinout & Package
DFN1010D-3 (SOT1215) is a leadless, ultra-thin (0.37 mm), 3-terminal surface-mount package with visible and solderable side pads; dimensions 1.05 × 1.15 × 0.37 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Accepts logic-level control signal; internal R1 connects here to emitter for current limiting. |
| 2 | GND (emitter) | Common reference node; ties internally to both resistor network and transistor emitter terminal. |
| 3 & 4 | Output (collector) | Dual-collector terminals reduce bond-wire inductance and improve current sharing at −100 mA. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Eliminates two external resistors, reducing BOM count and PCB area by >1.2 mm² vs discrete solution. |
| AEC-Q101 qualification | Validated for automotive ambient temperatures (−40 °C to +150 °C) and mechanical shock/vibration. |
| Low-profile DFN package | 0.37 mm height enables use in ultra-thin consumer wearables and space-constrained ADAS modules. |
| AOI-compatible side pads | Enables 100% automated optical inspection of solder joints without X-ray, improving manufacturing yield. |
| Reduced pick-and-place cost | Single-component placement replaces two parts (transistor + resistor pair), cutting placement time by ~30%. |
Applications
| Automotive Interior Lighting | Industrial Sensor Interface |
|---|---|

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 |
|---|---|---|---|
| PDTC143ZQA | NPN complement with same R1/R2 values; requires inverted logic drive and emitter-follower configuration. | Suitable only where load is connected to VCC (high-side switching), not ground-referenced loads. | Select when circuit topology mandates NPN-based sourcing rather than PNP sinking. |
| BC857B,215 | Discrete PNP BJT without integrated resistors; requires two external 4.7 kΩ/47 kΩ resistors. | Higher component count and larger footprint; lacks AEC-Q101 qualification and AOI compatibility. | Choose only if legacy design reuse or parametric fine-tuning (e.g., custom R1/R2) is required. |
Compared with PDTC143ZQA, PDTA143ZQAZ provides direct ground-referenced switching without logic inversion; compared with BC857B,215, it reduces layout area by 40% and eliminates resistor tolerance stack-up in production.

FAQ
What is the maximum continuous collector current for PDTA143ZQAZ?
The absolute maximum continuous collector current is −100 mA, verified under conditions of Tamb ≤ 25 °C on a 4-layer FR4 PCB. Derating applies above 25 °C per the published power derating curve; at 85 °C ambient, max sustainable current drops to approximately −65 mA to maintain Tj ≤ 150 °C.
Can PDTA143ZQAZ replace BC857 in existing designs?
Yes, as a drop-in functional replacement in most digital switching roles, provided the circuit uses emitter-grounded (low-side) configuration. The integrated 4.7 kΩ/47 kΩ bias network eliminates two external resistors, but VI(on) and VI(off) thresholds differ slightly-verify logic-high/low margins with your driver's VOH/VOL.
Is the DFN1010D-3 package compatible with standard reflow profiles?
Yes-the DFN1010D-3 package is qualified for JEDEC J-STD-020D reflow profiles. Recommended peak temperature is 260 °C for ≤ 30 seconds; solder land pattern matches IPC-7351B density level A, with 0.4 mm pad width and 0.75 mm center-to-center spacing per manufacturer footprint guidelines.
Does PDTA143ZQAZ support bidirectional signal routing?
No-it is a unidirectional PNP switch optimized for DC-controlled current sinking. Its structure lacks symmetrical terminal characteristics or specified reverse breakdown beyond VEBO = −5 V; it is not rated or characterized for AC signal coupling or bidirectional data transmission.
