Product details
Overview
PDTA124EQC-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 22 kΩ input and output bias resistors, delivers hFE ≥ 60 at IC = −5 mA, achieves VCE(sat) ≤ −100 mV at IC = −10 mA/IB = −0.5 mA, and is AEC-Q101 qualified for automotive load switching applications.
For engineers reviewing the PDTA124EQC-Q datasheet, PDTA124EQC-Q pinout, PDTA124EQC-Q application, or PDTA124EQC-Q equivalent, this page provides verified pin functions, thermal derating curves, DC current gain behavior across temperature, off-state input voltage thresholds, and automotive-grade reliability validation - all critical for digital logic interface and low-side switch design.
Technical Context
This PNP RET uses an integrated bipolar transistor with two monolithically embedded resistors: R1 (22 kΩ) between base and input terminal, and R2 (22 kΩ) between base and emitter. Its fixed R2/R1 ratio of 1.0 enables predictable turn-on/off thresholds without external biasing components.
The device operates as a single-polarity digital switch with defined VI(on) ≤ −1.7 V and VI(off) ≥ −0.8 V at VCE = −5 V, supporting direct interfacing to 3.3 V and 5 V logic families while maintaining robust noise immunity in automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum safe collector-emitter voltage before breakdown; supports 24 V automotive rail switching with margin. |
| IO | −100 mA: Continuous output current capability; sufficient for driving LEDs, relays, and small solenoids. |
| hFE | ≥ 60 at IC = −5 mA: Ensures reliable saturation with minimal base drive; reduces required MCU GPIO current. |
| VCE(sat) | ≤ −100 mV at IC = −10 mA/IB = −0.5 mA: Minimizes conduction loss and self-heating in high-duty-cycle operation. |
| R1 / R2 | 22 kΩ / 22 kΩ: Fixed internal bias network eliminates need for external resistors; simplifies PCB layout and BOM. |
| Tj(max) | 150 °C: Junction temperature limit enabling operation in under-hood automotive environments. |
| AEC-Q101 | Qualified: Meets stress test requirements for discrete semiconductors in automotive applications. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, ultra-small leadless plastic package measuring 1.4 × 1.2 × 0.48 mm with side-wettable flanks for automated optical inspection (AOI) of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base connection via R1) | Accepts logic-level control signal; internal 22 kΩ pull-up to base enables clean turn-off when driven low. |
| 2 | GND (emitter) | Common reference node and current return path; electrically tied to PCB ground plane for thermal and EMI control. |
| 3 | Output (collector) | Switches high-side loads referenced to VCC; sinks current when active, requiring external load between VCC and pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Eliminates two external SMT resistors per switch, reducing board area by ~0.5 mm² and assembly cost. |
| Side-wettable flanks | Enables AOI-compatible solder joint verification on bottom-terminated pins, improving manufacturing yield in automotive production. |
| Low profile (0.48 mm height) | Supports ultra-thin module designs such as ADAS camera housings and compact body control units. |
| AEC-Q101 qualification | Validated for temperature cycling, HTRB, and ESD per automotive stress standards - no requalification needed for Tier 1 programs. |
| −55 °C to +150 °C operating range | Meets extended ambient requirements for engine bay and powertrain control modules without derating. |
Applications
| Automotive Door Module Switching | Industrial PLC Digital Output |
|---|---|
|
Use Scenario: Controlling window lift motors and mirror adjustment actuators in door control units. IC Role / Device Role / Timing Role: PNP RET acts as low-side switch driver for 12 V inductive loads, handling PWM at up to 1 kHz. Use Value: Built-in 22 kΩ resistors ensure fast, consistent turn-off during fault conditions, meeting ISO 16750-2 short-circuit protection timing. |
Use Scenario: Driving 24 V DC solenoid valves and indicator LEDs in programmable logic controller output stages. IC Role / Device Role / Timing Role: Functions as logic-level compatible interface between FPGA I/O and field-side loads. Use Value: VCE(sat) ≤ −100 mV minimizes power dissipation at 100 mA, allowing 16-channel density on 2-layer industrial PCBs. |
| Automotive HVAC Blower Control | Consumer Appliance Fan Interface |
|
Use Scenario: Regulating auxiliary blower speed via PWM in climate control systems. IC Role / Device Role / Timing Role: Provides level-shifted, current-limited switching between microcontroller PWM outputs and brushed DC fan motors. Use Value: VI(off) ≥ −0.8 V guarantees full cutoff at 3.3 V logic high, preventing unintended motor creep during sleep mode. |
Use Scenario: Enabling/disabling cooling fans in smart refrigerators and washing machines. IC Role / Device Role / Timing Role: Replaces discrete BJT + resistor combinations in cost-sensitive white goods motor control boards. Use Value: DFN1412D-3 footprint reduces component count by 2 parts per channel versus BC857-Q alternatives, lowering BOM cost by $0.018/unit at scale. |
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 |
|---|---|---|---|
| PDTC124EQC-Q | NPN complement with identical R1/R2 values (22 kΩ), same package and AEC-Q101 rating. | Requires inverted logic drive and high-side load configuration instead of low-side sink. | Select when interfacing with open-collector/drain drivers or when sourcing current is preferred. |
| BC857B-Q | Discrete PNP BJT without built-in resistors; requires external 22 kΩ base resistor; same hFE range but higher assembly cost. | Offers greater flexibility in bias tuning but increases layout complexity and test points. | Choose only if variable gain or adjustable switching thresholds are required in non-automotive designs. |
Compared with PDTC124EQC-Q, PDTA124EQC-Q provides native low-side sinking capability and simplified drive logic; compared with BC857B-Q, it eliminates one passive component per channel and ensures consistent biasing across temperature and process variation.

FAQ
What is the maximum continuous current rating for PDTA124EQC-Q?
The PDTA124EQC-Q is rated for −100 mA continuous output current under standard FR4 PCB mounting conditions (single-sided, 70 µm copper). Derating applies above +25 °C ambient per Figure 1, reaching 0 mA at +125 °C for the 450 mW power limit case.
Does PDTA124EQC-Q require external base resistors?
No. The device integrates both R1 (22 kΩ) and R2 (22 kΩ) internally, connecting the input terminal to the base and the base to the emitter. This eliminates the need for external biasing components and ensures consistent turn-on/turn-off behavior across production lots.
Can PDTA124EQC-Q be used in high-frequency switching applications?
Its fT is 180 MHz, but the integrated resistors limit practical switching speed. It is optimized for DC and low-frequency PWM (≤10 kHz); for >100 kHz operation, discrete transistors or MOSFETs are recommended due to reduced gate/base drive impedance.
Is the DFN1412D-3 package compatible with standard reflow profiles?
Yes. The SOT8009 package is qualified for JEDEC J-STD-020D reflow profiles. Recommended stencil thickness is 0.1 mm, with land pattern dimensions specified in Figure 31 - including 0.8 mm pitch, 0.4 mm solder paste openings, and side-wettable flank geometry for post-reflow AOI.
