Product details
Overview
PDTC124XQC-Q from Nexperia is a 50 V, 100 mA NPN resistor-equipped transistor (RET) in a DFN1412D-3 (SOT8009) leadless SMD package with side-wettable flanks. It integrates R1 = 22 kΩ and R2 = 47 kΩ bias resistors, delivers VCE(sat) ≤ 100 mV at IC = 10 mA / IB = 0.5 mA, and supports automotive-grade operation per AEC-Q101. It functions as a digital switch for IC input control and low-power load switching in space-constrained PCBs.
For engineers reviewing the PDTC124XQC-Q datasheet, PDTC124XQC-Q pinout, PDTC124XQC-Q application, or PDTC124XQC-Q equivalent, this part serves as a drop-in replacement for BC847-Q series transistors in digital logic interface circuits-offering reduced BOM count, AOI-compatible solder joints, and validated thermal performance up to 150 °C junction temperature.
Technical Context
This RET implements a monolithic NPN transistor with two integrated silicon-based thin-film resistors: R1 connected between base and input terminal, and R2 between base and emitter. The internal topology eliminates external bias components while maintaining predictable DC current gain (hFE = 80 min at VCE = 5 V, IC = 5 mA) and tight VI(on) = 1.1–2.0 V range under switching conditions.
Designed for automotive-compliant digital signal conditioning, it operates across −55 °C to +150 °C ambient, sustains 50 V collector-emitter breakdown voltage, and achieves 230 MHz transition frequency (fT)-enabling reliable use in high-speed logic-level translation and microcontroller GPIO interfacing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IO | 100 mA - Continuous output current rating; sufficient for driving LEDs, small relays, or logic inputs without external heatsinking. |
| R1 / R2 | 22 kΩ / 47 kΩ - Precisely trimmed on-die resistors that set base biasing; eliminate need for two external SMT resistors and reduce layout area by ~1.5 mm². |
| VCE(sat) | ≤100 mV @ IC=10 mA, IB=0.5 mA - Low saturation voltage minimizes power loss (≤1 mW) and ensures clean logic-low output during switching. |
| hFE | 80 min @ VCE=5 V, IC=5 mA - Guaranteed DC current gain ensures stable switching behavior even at elevated temperatures (Tj ≤ 150 °C). |
| fT | 230 MHz - Transition frequency confirms suitability for digital signals up to ~20 MHz edge rates without significant gain roll-off. |
| Package | DFN1412D-3 (SOT8009) - 1.4 × 1.2 × 0.48 mm ultra-small leadless package with side-wettable flanks for automated optical inspection of solder joints. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, leadless plastic package with 0.8 mm pitch, 0.5 mm max height, and side-wettable flanks for IPC-A-610 Class 2/3 solder joint verification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connects to control signal source; internal R1 pulls base toward this node for turn-on biasing. |
| 2 | GND (emitter) | Common reference and current return path; tied internally to emitter and R2 bottom node. |
| 3 | Output (collector) | Switched high-side output node; sinks load current when device is active; rated for 50 V standoff. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic R1 = 22 kΩ + R2 = 47 kΩ reduces component count by two resistors and eliminates matching tolerance errors. |
| AEC-Q101 qualification | Qualified for automotive applications including engine control modules and body electronics with full stress-test validation. |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder fillets on all three terminals-critical for zero-defect manufacturing in Tier-1 supply chains. |
| Low profile (0.48 mm) | Supports ultra-thin end equipment such as ADAS camera modules and compact infotainment displays where Z-height is constrained. |
| Thermal derating | Rated for 450 mW total power dissipation on 70 µm copper FR4 PCB; maintains functionality up to 125 °C ambient with linear derating above 25 °C. |

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 |
|---|---|---|---|
| PDTC143XQC-Q | R1 = 4.7 kΩ, R2 = 10 kΩ; higher base drive sensitivity but lower input impedance (5.7 kΩ vs 22 kΩ). | Better suited for low-voltage CMOS outputs (1.8 V logic); less tolerant of leakage-induced false triggering in noisy environments. | Select when driving from weak-sourcing MCU pins or when faster turn-on is required at expense of noise immunity. |
| BC847B-Q | Discrete NPN transistor without integrated resistors; requires external RB and RBE; hFE = 200–450 (vs 80 min for PDTC124XQC-Q). | Offers higher gain and lower VCE(sat) (65 mV) but increases BOM count, layout area, and assembly cost. | Choose only if maximum current efficiency is critical and board space/cost constraints allow two extra 0402 resistors. |
Compared with PDTC143XQC-Q, PDTC124XQC-Q provides superior noise immunity due to higher R1 value, while BC847B-Q trades integration for raw performance-making PDTC124XQC-Q optimal for cost-sensitive, high-reliability digital interface designs where footprint and testability are prioritized.

FAQ
What is the maximum operating temperature for PDTC124XQC-Q?
The PDTC124XQC-Q has a maximum junction temperature (Tj) of 150 °C and an ambient operating range of −55 °C to +150 °C. Its thermal resistance Rth(j-a) is 278 K/W on a 70 µm copper FR4 PCB, allowing continuous operation at 125 °C ambient when dissipating ≤220 mW-verified per AEC-Q101 thermal stress testing.
Can PDTC124XQC-Q replace BC847B-Q directly on PCB?
No direct footprint replacement is possible: PDTC124XQC-Q uses DFN1412D-3 (SOT8009), while BC847B-Q typically uses SOT23. However, functionally it replaces BC847B-Q + two bias resistors-requiring schematic update to remove external RB and RBE, and PCB redesign to accommodate the smaller 1.4 × 1.2 mm land pattern with side-wettable flanks.
How does the integrated R1/R2 affect input threshold voltage?
The 22 kΩ/47 kΩ resistor network sets VI(on) = 1.1–2.0 V and VI(off) = 0.3–0.5 V (typical), creating a well-defined Schmitt-like input window. This improves noise margin versus discrete biasing-especially in 12 V automotive environments-by rejecting transients below 0.5 V and ensuring turn-on only above 1.1 V.
Is PDTC124XQC-Q suitable for PWM-driven LED dimming?
Yes-its 100 mA IO rating, 100 mV VCE(sat), and 230 MHz fT support PWM frequencies up to 50 kHz with minimal switching loss. Thermal data shows 450 mW Ptot capability on standard FR4, enabling 100 mA LED drive at 50% duty cycle without derating-validated in Nexperia's lighting reference design AN11321.
