Product details
Overview
PDTC143ZQB-Q from Nexperia is a 50 V, 100 mA NPN resistor-equipped transistor (RET) in a DFN1110D-3 (SOT8015) leadless package with side-wettable flanks. It integrates 4.7 kΩ input bias resistor (R1) and 47 kΩ feedback resistor (R2), enabling direct logic-level switching without external base resistors. Designed for digital load control and IC input interfacing in space-constrained automotive and industrial PCBs.
For engineers reviewing the PDTC143ZQB-Q datasheet, PDTC143ZQB-Q pinout, PDTC143ZQB-Q application, or PDTC143ZQB-Q equivalent, this device serves as a drop-in replacement for BC847-Q series transistors in digital switching circuits where board area, solder joint inspection, and AEC-Q101 compliance are critical.
Technical Context
This RET implements a monolithic NPN transistor with two integrated silicon-based thin-film resistors-R1 connected between base and input terminal, R2 between base and emitter-forming a fixed-current bias network. The internal transistor exhibits hFE ≥ 100 at IC = 10 mA, VCE = 5 V, and VCE(sat) ≤ 100 mV under same conditions.
The DFN1110D-3 package features 0.65 mm pitch, 1.1 × 1.0 × 0.48 mm body dimensions, and side-wettable flanks to support automated optical inspection (AOI) of solder joints. Thermal resistance Rth(j-a) is 298 K/W on 70 µm FR4 copper, enabling stable operation up to Tj = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V and 36 V rail switching with margin. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, and logic inputs. |
| R1 / R2 | 4.7 kΩ / 47 kΩ - Fixed internal bias network eliminates need for external base resistors and reduces BOM count. |
| VCE(sat) | ≤ 100 mV at IC = 10 mA, IB = 0.5 mA - Low saturation voltage minimizes power loss and self-heating during switching. |
| hFE | ≥ 100 at VCE = 5 V, IC = 10 mA - Predictable DC gain enables reliable digital on/off behavior without gain variation compensation. |
| Tj(max) | 150 °C - Junction temperature limit qualified per AEC-Q101; ensures reliability in under-hood automotive environments. |
| Package | DFN1110D-3 (SOT8015) - 0.48 mm height, side-wettable flanks, and 0.65 mm pitch enable high-density routing and AOI-compatible assembly. |
Pinout & Package
DFN1110D-3 (SOT8015) is an ultra-thin, leadless surface-mount package measuring 1.1 mm × 1.0 mm × 0.48 mm with three terminals and side-wettable flanks for solder joint inspection. Its low profile (0.5 mm max height) suits slim consumer and automotive modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connects to logic signal source; internal R1 routes current into base node for transistor turn-on. |
| 2 | GND (emitter) | Emitter tied to system ground; internal R2 connects base to this terminal, forming feedback path for stable biasing. |
| 3 | Output (collector) | Switched high-side output node; sinks load current when transistor is saturated; rated for 50 V and 100 mA continuous. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Eliminates two external components per switch channel, reducing layout area and pick-and-place steps. |
| AEC-Q101 qualification | Qualified for automotive applications including body control modules and sensor interface circuits. |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, improving manufacturing yield verification. |
| Low package height (0.48 mm) | Supports ultra-thin end equipment such as infotainment displays and compact ECUs where Z-height is constrained. |
| Logic-level compatible input | VI(on) = 0.9–1.3 V at IC = 5 mA enables direct drive from 1.8 V, 3.3 V, and 5 V microcontrollers without level shifting. |
Applications
| LED Driver Circuit | Microcontroller GPIO Expander |
|---|---|
Use Scenario: Driving 20 mA indicator LEDs from MCU GPIO pins with limited drive strength. IC Role / Device Role / Timing Role: Acts as a low-side switch that translates weak GPIO signals into robust current-sinking paths. Use Value: Eliminates need for discrete base resistor and saves 0.5 mm² PCB area per LED channel while ensuring consistent brightness across temperature. |
Use Scenario: Extending digital I/O count in space-limited industrial controllers using parallel transistor arrays. IC Role / Device Role / Timing Role: Functions as a buffered digital output stage, isolating MCU pins from relay coils and optocoupler inputs. Use Value: Reduces component count by 2× per channel versus discrete BJT + resistor solution, accelerating assembly and lowering test complexity. |
| Automotive Door Module | USB-C Port Power Switch |
Use Scenario: Controlling window motor enable lines and mirror position sensor interfaces in AEC-Q101-compliant door modules. IC Role / Device Role / Timing Role: Provides fail-safe digital switching with defined off-state leakage (<170 µA) and thermal derating up to 125 °C ambient. Use Value: Meets automotive transient immunity requirements without additional protection circuitry due to built-in resistor network stability. |
Use Scenario: Enabling/disabling VBUS power paths in USB-C receptacles based on CC logic detection. IC Role / Device Role / Timing Role: Serves as a compact, low-RDS(on)-equivalent switch with fast turn-on (<100 ns typical propagation delay). Use Value: Achieves <100 mV dropout at 100 mA while occupying only 1.1 mm² footprint-critical for multi-port dongles with tight thermal budgets. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PDTC143XQB-Q | R1 = 4.7 kΩ, R2 = 10 kΩ → lower R2/R1 ratio (2.13) yields higher base current and faster turn-on but higher input power. | Better suited for high-speed digital switching (>1 MHz) where reduced propagation delay outweighs input power penalty. | Select when driving capacitive loads or requiring ton < 35 ns; avoid if input voltage swing is limited to 1.8 V. |
| BC847B-Q | Discrete NPN BJT without integrated resistors; requires external 10 kΩ base resistor and occupies larger SOT23 footprint. | Offers higher hFE (200–450) and wider VCEO margin (65 V), but increases BOM count and layout complexity. | Choose when precise gain control or higher voltage tolerance is required; not recommended for AOI-dependent production lines. |
Compared with PDTC143XQB-Q, PDTC143ZQB-Q provides higher R2 for improved noise immunity in noisy automotive environments; compared with BC847B-Q, it trades discrete flexibility for guaranteed bias stability and 40% smaller footprint.

FAQ
What is the maximum allowable input voltage (VI) for PDTC143ZQB-Q?
The absolute maximum input voltage is +30 V with VE = 0 V, as specified in Table 6. However, for reliable operation in digital logic interfaces, the recommended VI(on) range is 0.9 V to 1.3 V at IC = 5 mA, and VI(off) must remain below 0.5 V to ensure full cutoff. Exceeding +30 V risks permanent damage to the internal R1 resistor network.
Can PDTC143ZQB-Q be used in linear amplifier configurations?
No-it is optimized exclusively for digital switching operation. Its integrated R1/R2 network fixes the base bias point, preventing adjustable quiescent current setting. The datasheet specifies no linearity parameters (e.g., THD, fT stability over bias), and hFE variation across IC is not characterized for analog use. Use discrete transistors like BC847B-Q for amplification.
How does the side-wettable flank design impact reflow soldering?
The side-wettable flanks extend the copper terminations vertically along the package edges, allowing solder paste to wick upward during reflow and form visible fillets. This enables standard AOI systems to inspect solder joint integrity without X-ray, improving first-pass yield in high-volume automotive assembly lines using the recommended stencil thickness of 0.1 mm and land pattern from Figure 37.
Is thermal derating required when operating above 25 °C ambient?
Yes-total power dissipation must be derated linearly above 25 °C. At 70 °C ambient, Ptot drops to ~280 mW (based on 298 K/W Rth(j-a) on 70 µm FR4). Derating follows the curve in Figure 1: for every 1 °C rise above 25 °C, Ptot decreases by 2.8 mW. Operation beyond 125 °C ambient requires forced convection or PCB copper thermal spreading.
