Product details
Overview
PDTA143XQB-QZ from Nexperia is a 50 V, 100 mA PNP resistor-equipped transistor (RET) in a leadless DFN1110D-3 (SOT8015) package with side-wettable flanks. It integrates 4.7 kΩ input and 10 kΩ feedback bias resistors, delivers −100 mV VCE(sat) at −10 mA/−0.5 mA drive, and is AEC-Q101 qualified for automotive load switching and IC input control.
For engineers reviewing the PDTA143XQB-QZ datasheet, PDTA143XQB-QZ pinout, PDTA143XQB-QZ application, or PDTA143XQB-QZ equivalent, this part serves as a space-optimized, AOI-compatible digital switch with built-in biasing-ideal for replacing BC857-Q series transistors in low-voltage logic interface and power rail control circuits.
Technical Context
This PNP RET uses an integrated bipolar junction transistor with two monolithically embedded resistors: R1 (4.7 kΩ) connects base to input, and R2 (10 kΩ) connects base to emitter, enabling single-resistor external drive and stable saturation under varying temperature conditions. Its −50 V VCEO rating supports robust operation in 24 V automotive subsystems.
The DFN1110D-3 package features side-wettable flanks for automated optical inspection of solder joints and achieves 0.5 mm profile height-critical for ultra-thin portable and ADAS module designs. Thermal resistance is 298 K/W on 70 µm FR4 PCB, supporting continuous 100 mA output with derating above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Withstands reverse collector-emitter voltage up to 50 V, suitable for 24 V automotive supply rails with transient margin. |
| IO | −100 mA: Continuous DC output current capability enables direct driving of small relays, LEDs, or logic inputs without external amplification. |
| R1 / R2 | 4.7 kΩ / 10 kΩ: Fixed internal bias network eliminates need for two external resistors, reducing BOM count and layout area by ~30% vs discrete solutions. |
| VCE(sat) | −100 mV @ −10 mA/−0.5 mA: Low saturation voltage minimizes power loss (≤1 mW at 10 mA), critical for battery-powered and thermally constrained applications. |
| hFE | 50 min @ −5 V/−10 mA: Guaranteed DC current gain ensures reliable turn-on across industrial temperature range (−40 °C to +125 °C). |
| Tj max | 150 °C: Maximum junction temperature supports operation in under-hood automotive environments with appropriate PCB copper area. |
Pinout & Package
DFN1110D-3 (SOT8015) is a 3-terminal, leadless, ultra-thin surface-mount package measuring 1.1 × 1.0 × 0.48 mm with side-wettable flanks for AOI-compliant reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Accepts TTL/CMOS-level logic signal; internally connected to R1 (4.7 kΩ) and R2 (10 kΩ) network for self-biasing. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; forms common reference for input and output paths in high-side switching configurations. |
| 3 | Output (collector) | Delivers switched current to load; polarity is PNP-current flows from emitter (pin 2) to collector (pin 3) when active. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Qualified per stress test standard for discrete semiconductors-enables use in automotive body electronics, lighting, and infotainment without additional reliability screening. |
| Side-wettable flanks | Enables 100% automated optical inspection of solder joint integrity on bottom terminals-reducing post-reflow defect escapes in high-volume SMT lines. |
| 0.5 mm package height | Ultra-low profile allows integration into space-constrained modules such as camera ECU housings and compact sensor nodes. |
| −7 V VEBO | Emitter-base breakdown voltage supports safe operation with negative-going transients on emitter-referenced inputs in mixed-signal systems. |
Applications
| Automotive Lighting Control | Industrial I/O Module |
|---|---|
|
Use Scenario: Switching 12 V LED strings in headlamp or interior lighting modules with PWM dimming. IC Role / Device Role / Timing Role: High-side PNP switch controlling current path from battery rail to LED cathode; operates in saturated mode for minimal conduction loss. Use Value: Built-in R1/R2 eliminates external bias components, reducing footprint by 0.5 mm² and enabling placement directly adjacent to LED drivers on dense PCBs. |
Use Scenario: Level-shifting and isolating PLC digital outputs to 24 V field devices. IC Role / Device Role / Timing Role: Digital interface buffer translating 3.3 V microcontroller GPIO to 24 V sink/sourcing capability with fast turn-off (<100 ns propagation delay). Use Value: −100 mV VCE(sat) ensures <1 mW dissipation at 10 mA, eliminating thermal derating concerns in fanless DIN-rail enclosures. |
| Consumer Power Management | Automotive Body Control Unit |
|
Use Scenario: Enabling/disabling USB-C port power delivery circuitry in portable docking stations. IC Role / Device Role / Timing Role: Load switch for 5 V VBUS line; driven by MCU GPIO with no external pull-up or current-limiting resistor required. Use Value: Single-pin input simplifies firmware control logic and reduces PCB routing complexity-no risk of floating base or unintended turn-on during reset. |
Use Scenario: Controlling window lift motor direction logic in door module ECUs. IC Role / Device Role / Timing Role: Signal conditioner for H-bridge enable lines; provides noise immunity and current gain for weak microcontroller outputs. Use Value: AEC-Q101 qualification and −50 V VCEO ensure robustness against load-dump transients (ISO 7637-2 Pulse 5a) without added TVS protection. |
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 |
|---|---|---|---|
| PDTC143XQB-Q | NPN complement with identical R1/R2 values (4.7 kΩ/10 kΩ), same DFN1110D-3 package, but opposite polarity and +50 V VCEO. | Suitable for low-side switching only; requires inverted logic drive and cannot replace PDTA143XQB-Q in high-side configurations. | Select when sinking current from grounded loads is preferred and board layout allows NPN orientation. |
| PDTA123JQB-Q | Same PNP RET architecture but with 2.2 kΩ/47 kΩ bias network, lower hFE (100 min), and −5 V VEBO instead of −7 V. | Better suited for 3.3 V logic interfaces where lower input threshold is needed; less tolerant of emitter-referenced negative transients. | Choose for cost-sensitive consumer applications with 3.3 V MCU outputs and no automotive qualification requirement. |
Compared with PDTC143XQB-Q and PDTA123JQB-Q, PDTA143XQB-Q offers higher VEBO and high-side switching capability-making it uniquely suitable for automotive 12 V/24 V rail control where polarity, transient immunity, and space constraints converge.

FAQ
What is the maximum allowable input voltage (VI) for PDTA143XQB-QZ?
The absolute maximum input voltage is −30 V to +7 V, as specified in Table 6. This range accommodates both negative transients (e.g., load dump coupling) and positive overvoltage events while maintaining safe bias network operation. Operation outside this range risks permanent damage to the integrated resistors or transistor junction.
Can PDTA143XQB-QZ be used in high-frequency switching applications?
No-it is optimized for DC and low-frequency digital switching (≤100 kHz). Its transition frequency (fT) is not characterized, and its internal resistor network introduces RC delays that limit edge rates. For PWM dimming above 1 kHz, verify VCE(sat) stability and thermal rise under actual duty cycle conditions.
How does the side-wettable flank design improve manufacturing yield?
The exposed copper on the package sidewalls enables automated optical inspection (AOI) to verify solder fillet formation and wetting quality-detecting voids, insufficient solder, or bridging that would otherwise require X-ray or ICT. This reduces field failure rates in high-volume automotive assembly without adding process steps.
Is the marking code 'D6' unique to PDTA143XQB-QZ?
Yes-per Table 5, 'D6' is the official top-side laser marking for PDTA143XQB-QZ. It distinguishes this variant from other members of the series (e.g., 'D2' for PDTA123JQB-Q), ensuring traceability during automated pick-and-place and post-solder verification.
