Product details
Overview
PDTA124XQC-Q from Nexperia is a 50 V, 100 mA PNP resistor-equipped transistor (RET) in a DFN1412D-3 (SOT8009) leadless package with side-wettable flanks. It integrates R1 = 22 kΩ and R2 = 47 kΩ bias resistors, delivers hFE = 80 at IC = −5 mA / VCE = −5 V, achieves VCEsat ≤ −100 mV at IC = −10 mA / IB = −0.5 mA, and is AEC-Q101 qualified for automotive digital switching applications.
For engineers reviewing the PDTA124XQC-Q datasheet, PDTA124XQC-Q pinout, PDTA124XQC-Q application, or PDTA124XQC-Q equivalent, this RET simplifies load switching and IC input control by eliminating external base resistors while supporting AOI-compatible reflow assembly in ultra-compact space-constrained designs.
Technical Context
This PNP RET uses an integrated bipolar transistor with two monolithically embedded silicon resistors: R1 connects base to input terminal, R2 connects base to emitter. The fixed R2/R1 ratio of 2.13 enables predictable saturation behavior across temperature (−40 °C to +150 °C) without external tuning.
Its DFN1412D-3 package features 0.8 mm pitch, 1.4 × 1.2 × 0.48 mm body, and side-wettable flanks for automated optical inspection of solder joints - critical for automotive PCB assembly traceability and reliability validation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum collector-emitter voltage before breakdown; supports robust operation in 24 V automotive supply rails with margin. |
| IO | −100 mA: Continuous DC output current capability; sufficient for driving LEDs, small relays, or logic inputs. |
| R1 | 22 kΩ: Input bias resistor value; sets base current for defined turn-on threshold and power efficiency. |
| R2/R1 | 2.13: Fixed internal resistor ratio; ensures stable saturation and prevents latch-up under varying temperature conditions. |
| hFE | 80 at IC = −5 mA / VCE = −5 V: DC current gain enabling low-input-current switching with predictable gain stability. |
| VCEsat | ≤ −100 mV at IC = −10 mA / IB = −0.5 mA: Low saturation voltage minimizes conduction loss and self-heating in high-duty-cycle operation. |
| VI(on) | −2.0 to −1.1 V at IC = −2 mA / VCE = −0.3 V: Validated on-state input voltage range ensuring reliable activation across process and temperature variation. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, leadless, ultra-small surface-mount package with 0.8 mm pitch, 1.4 × 1.2 × 0.48 mm body dimensions, and side-wettable flanks for AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connects to control signal; current flows through R1 into base node to enable transistor conduction. |
| 2 | GND (emitter) | Emitter reference terminal; tied to system ground; provides return path for load current and R2 connection. |
| 3 | Output (collector) | Switched output node; sinks up to 100 mA from connected load to emitter (ground) when active. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 and R2 bias network | Eliminates two external resistors per switch, reducing BOM count and PCB real estate in multi-channel digital interfaces. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock per JEDEC standards. |
| Side-wettable flanks | Enables automated optical inspection of solder fillets on all three terminals - essential for zero-defect automotive manufacturing. |
| Low profile (0.48 mm height) | Supports ultra-thin module designs such as ADAS sensors and infotainment front panels where Z-height is constrained. |
Applications
| Automotive Door Module Control | Industrial PLC Digital Input Conditioning |
|---|---|
Use Scenario: Switching window lift motor drivers and mirror position actuators in door control units. IC Role / Device Role: PNP RET acts as level-shifted, current-limited interface between 3.3 V microcontroller GPIO and 12 V/24 V loads. Use Value: Built-in R1/R2 eliminates discrete resistor placement errors and reduces assembly steps in high-volume automotive harness modules. |
Use Scenario: Converting 24 V industrial field signals to 5 V logic levels for FPGA or MCU input capture. IC Role / Device Role: Acts as a ruggedized, current-limited input buffer protecting downstream logic from transients and overvoltage. Use Value: −50 V VCEO rating and AEC-Q101 qualification ensure long-term reliability in noisy factory environments with ESD and surge exposure. |
| Consumer Appliance Power Sequencing | Medical Diagnostic Equipment Signal Isolation |
Use Scenario: Enabling sequential power-up of display backlight, sensor array, and communication subsystems in smart ovens. IC Role / Device Role: Functions as a low-power, thermally efficient load switch controlling 10–50 mA auxiliary rails. Use Value: ≤ −100 mV VCEsat minimizes self-heating during continuous operation, extending thermal margin in sealed enclosures. |
Use Scenario: Isolating analog sensor excitation lines from digital control logic in portable ultrasound probes. IC Role / Device Role: Provides galvanic separation via open-collector switching while maintaining precise timing alignment. Use Value: 180 MHz fT and low Cc (≤3 pF) preserve signal integrity for fast-switching diagnostic pulses without added propagation delay. |
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 |
|---|---|---|---|
| PDTC124XQC-Q | NPN complement with identical R1/R2 values (22 kΩ / 47 kΩ), same package, but opposite polarity and VCEO = +50 V. | Used where sink-switching (NPN) is required instead of source-switching (PNP); not interchangeable without circuit redesign. | Select PDTC124XQC-Q only when load must be connected to VCC and switched to ground. |
| BC857B-Q | Discrete PNP transistor without built-in resistors; requires two external base resistors; same SOT323 package but no side-wettable flanks. | Lacks AOI support and increases component count; suitable only for non-automotive cost-sensitive designs with manual inspection. | Choose BC857B-Q only if resistor values must be user-adjustable or footprint compatibility with legacy SOT323 layouts is mandatory. |
Compared with PDTC124XQC-Q, PDTA124XQC-Q provides source-switching topology and automotive-grade AOI readiness; compared with BC857B-Q, it reduces bill-of-materials and improves manufacturability at the cost of fixed bias configuration.

FAQ
What is the maximum ambient temperature for continuous operation of PDTA124XQC-Q?
The device supports continuous operation from −55 °C to +150 °C ambient temperature. Its junction temperature limit is 150 °C, and thermal resistance Rth(j-a) is 278 K/W on a 70 µm copper FR4 PCB - enabling reliable use in under-hood automotive locations with proper board layout.
Can PDTA124XQC-Q replace BC857B in existing designs without modification?
No. PDTA124XQC-Q integrates R1 = 22 kΩ and R2 = 47 kΩ, fixing the base bias network. Replacing BC857B requires removing external resistors and verifying that the resulting drive strength, switching speed, and saturation voltage meet system requirements - layout and firmware timing may need adjustment.
Is the DFN1412D-3 package compatible with standard reflow profiles?
Yes. The DFN1412D-3 (SOT8009) package is qualified for IPC/JEDEC J-STD-020D reflow profiles. Recommended stencil thickness is 0.1 mm, and the side-wettable flanks support post-reflow AOI - no special process changes are needed beyond standard lead-free reflow settings.
What does the marking code '6F' indicate on PDTA124XQC-Q?
The top-side marking '6F' is the unique identifier for PDTA124XQC-Q per Nexperia's ordering matrix. It distinguishes this variant from other members of the series (e.g., '8F' for PDTA143XQC-Q) and corresponds directly to R1 = 22 kΩ / R2 = 47 kΩ configuration in the DFN1412D-3 package.
