Product details
Overview
PDTA124EQC from Nexperia is a 50 V, 100 mA PNP resistor-equipped transistor (RET) in a DFN1412D-3 (SOT8009) leadless SMD package with side-wettable flanks. It integrates 22 kΩ input and 22 kΩ base-emitter bias resistors, delivers −100 mA output current, exhibits −1.1 V to −0.8 V off-state input voltage, and achieves 60× minimum DC current gain at −5 V VCE and −5 mA IC. It serves as a compact, low-height (0.48 mm body height) digital switch for IC input control and load switching in space-constrained consumer and industrial PCBs.
For engineers reviewing the PDTA124EQC datasheet, PDTA124EQC pinout, PDTA124EQC application, or PDTA124EQC equivalent, this page provides verified electrical parameters, validated pin functions, confirmed thermal derating curves, real-world use cases in digital logic interfacing, and cross-reference alternatives with documented R1/R2 resistor and hFE differences.
Technical Context
This PNP RET integrates two precision-matched 22 kΩ resistors (R1 = R2) to form a built-in voltage divider that biases the internal transistor, eliminating external base resistors. Its design enables direct connection to CMOS/TTL logic outputs without additional components.
The device operates with open-base collector-emitter breakdown voltage of −50 V, supports −100 mA continuous output current, and maintains stable hFE ≥ 60 across −40 °C to +100 °C ambient range - enabling reliable on/off switching in digital interface circuits where predictable turn-on/off thresholds are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V: Maximum allowable collector-emitter voltage before breakdown; defines safe operating voltage headroom in high-side switching. |
| IO | −100 mA: Continuous output current capability; supports driving moderate loads such as LED indicators or small relays. |
| hFE | ≥ 60 at −5 V VCE, −5 mA IC: Minimum DC current gain ensures sufficient drive strength with low base current demand. |
| R1 / R2 | 22 kΩ / 22 kΩ: Matched integrated bias resistors eliminate external components and reduce BOM count in digital switching designs. |
| VI(off) | −1.1 V to −0.8 V: Input voltage threshold below which the device remains fully off; enables clean logic-level compatibility with 3.3 V/5 V systems. |
| Ptot | 450 mW (70 µm Cu PCB): Total power dissipation limit under standard mounting; determines thermal margin in compact layouts. |
| Tj | 150 °C maximum junction temperature: Sets upper thermal boundary for reliability in sealed or high-ambient environments. |
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 AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connects to external logic signal; internal R1 resistor routes current to base node for controlled turn-on. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; forms return path for load current and reference for input voltage thresholds. |
| 3 | Output (collector) | Switched high-side output node; sinks up to −100 mA when active, suitable for driving loads between VCC and collector. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Matched 22 kΩ R1 and R2 resistors enable resistor-free digital interface without external components. |
| Ultra-low profile | 0.48 mm body height minimizes Z-axis space usage in thin-profile portable and wearable electronics. |
| Side-wettable flanks | Facilitates automated optical inspection (AOI) of solder joints, improving manufacturing yield and quality traceability. |
| High hFE consistency | Minimum hFE ≥ 60 ensures predictable saturation behavior across temperature and production lots. |
| Logic-compatible thresholds | VI(on) ≤ −1.7 V and VI(off) ≥ −1.1 V guarantee robust switching with standard 3.3 V CMOS outputs. |
Applications
| LED Indicator Control | Digital Input Conditioning |
|---|---|
Use Scenario: Driving discrete status LEDs from microcontroller GPIO pins with limited sink current capability. IC Role / Device Role: High-side PNP switch sourcing current from VCC through LED to grounded cathode. Use Value: Eliminates need for external base resistor and pull-up, reducing component count by two per channel while maintaining <100 mA drive. |
Use Scenario: Converting noisy or floating digital signals into clean, rail-referenced inputs for FPGA or ASIC configuration pins. IC Role / Device Role: Level-shifting and noise-immune signal conditioning via guaranteed VI(off)/VI(on) hysteresis. Use Value: Built-in 22 kΩ resistors provide defined input impedance and prevent false triggering in electrically noisy industrial control panels. |
| Load Switching in Portable Devices | BC857 Series Replacement |
Use Scenario: Enabling/disabling peripheral modules (e.g., sensors, RF transceivers) in battery-powered wearables to minimize standby leakage. IC Role / Device Role: Low-leakage (≤ −180 nA ICEO) PNP switch controlling VCC supply path to downstream circuitry. Use Value: 0.48 mm profile and 1.4 × 1.2 mm footprint save board area versus SO-23 packages, critical in compact PCBs. |
Use Scenario: Drop-in replacement for BC857B in legacy digital logic circuits requiring identical pinout and biasing. IC Role / Device Role: Pin-compatible PNP transistor with integrated biasing, simplifying redesign of existing BC857-based schematics. Use Value: Reduces bill-of-materials by removing two external resistors per channel and lowers pick-and-place cost in high-volume assembly. |
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 |
|---|---|---|---|
| PDTA114EQC | R1 = R2 = 10 kΩ; hFE min = 30; higher input current requirement | Better suited for higher-speed switching due to lower R1, but less noise margin in weak-drive scenarios | Select when driving from low-impedance sources or requiring faster turn-on at expense of off-state immunity |
| PDTA144EQC | R1 = R2 = 47 kΩ; hFE min = 80; lower input current, higher gain | Optimized for ultra-low-power MCU GPIOs with limited drive strength; slower switching due to higher R1 | Choose for battery-critical applications where input current must stay below −105 μA and gain stability >80 is required |
Compared with PDTA114EQC and PDTA144EQC, PDTA124EQC offers balanced performance: its 22 kΩ resistors provide superior noise immunity over PDTA114EQC while maintaining faster response than PDTA144EQC, making it ideal for general-purpose digital interfacing where both robustness and speed matter.

FAQ
What is the maximum continuous collector current for PDTA124EQC?
The PDTA124EQC supports a maximum continuous output current of −100 mA under standard FR4 PCB conditions (70 µm copper, single-sided). This rating assumes ambient temperature ≤ 25 °C and derates linearly above that point, reaching zero at approximately +125 °C ambient based on the 450 mW total power dissipation limit.
Does PDTA124EQC require external base resistors?
No. PDTA124EQC integrates matched 22 kΩ R1 (input-to-base) and R2 (base-to-emitter) resistors, enabling direct connection to logic outputs without external bias components. This eliminates two passive parts per channel and reduces layout complexity in digital switching applications.
How does the DFN1412D-3 package support automated optical inspection?
The DFN1412D-3 (SOT8009) package features side-wettable flanks - exposed metal on the vertical edges of the terminals - allowing AOI systems to inspect solder fillet formation and wetting quality from the side, significantly improving defect detection rates compared to traditional bottom-only terminations.
Can PDTA124EQC replace BC857B in existing designs?
Yes - PDTA124EQC is a functional and pin-compatible upgrade to BC857B in digital switching roles. It retains the same SOT23-3 pinout (1=base, 2=emitter, 3=collector), adds integrated biasing, and improves board-area efficiency via its smaller DFN1412D-3 footprint. No schematic changes are needed beyond removing external base resistors.
