Product details
Overview
PDTA123JQC 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 2.2 kΩ input bias resistor (R1) and 47 kΩ feedback resistor (R2), delivers hFE = 100 at IC = −5 mA / VCE = −5 V, achieves VCE(sat) ≤ −100 mV, and is used for digital switching of IC inputs and low-power loads in space-constrained consumer and industrial PCBs.
For engineers reviewing the PDTA123JQC datasheet, PDTA123JQC pinout, PDTA123JQC application, or PDTA123JQC equivalent, this page provides verified electrical parameters, validated pin functions, confirmed thermal derating curves, real-world switching use cases, and cross-referenced alternatives for discrete logic-level PNP switching in high-density layouts.
Technical Context
This RET implements a monolithic PNP bipolar transistor with two integrated on-die resistors: R1 connects base to input terminal, R2 connects base to emitter, enabling single-pin control without external bias components. Its fixed R2/R1 ratio of 21 ensures stable saturation under varying drive conditions.
Designed for digital interface applications, it operates with VI(on) = −0.75 V (typ.) at IC = −5 mA and VI(off) = −0.6 V (min.) at VCE = −5 V, supporting clean TTL/CMOS-compatible switching while maintaining <100 nA ICEO leakage up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 3.3 V–24 V rail-switching applications. |
| IO | −100 mA - Continuous output current capability; supports driving LEDs, small relays, or logic inputs without external current limiting. |
| hFE | 100 (typ.) at VCE = −5 V, IC = −5 mA - Confirmed DC current gain ensuring reliable saturation with low base drive current. |
| VCE(sat) | ≤ −100 mV - Low saturation voltage minimizes power loss and heat generation during active switching. |
| R1 / R2 | 2.2 kΩ / 47 kΩ - Precisely trimmed internal resistors eliminate need for external bias network and reduce BOM count by one component. |
| Tj(max) | 150 °C - Maximum junction temperature rating allows operation in thermally demanding environments without derating below 100 mA. |
| Package | DFN1412D-3 (SOT8009) - 1.4 × 1.2 × 0.48 mm ultra-small leadless package with side-wettable flanks for AOI-compatible reflow soldering. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, leadless plastic package with 0.8 mm pitch, 0.48 mm body height, and side-wettable flanks for automated optical inspection of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connects to external control signal; internally tied to R1 top node and R2 top node - sole logic input point. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference for both R1 and R2; carries full load current. |
| 3 | Output (collector) | Switched output node; sinks current from load connected between VCC and pin 3; electrically isolated from bias network. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | Monolithic 2.2 kΩ + 47 kΩ resistor pair eliminates external base resistors and reduces layout area by ≥1.5 mm². |
| Low-profile packaging | 0.48 mm max height enables use in ultra-thin devices such as wearables and slim IoT sensors where Z-axis clearance is constrained. |
| Side-wettable flanks | Exposed copper sidewalls on all three terminals support automated optical inspection (AOI) of solder fillets without X-ray. |
| Thermal robustness | Rth(j-a) = 278 K/W on 70 µm FR4 PCB enables 100 mA continuous operation at ambient up to 85 °C without heatsinking. |
Applications
| LED Indicator Control | Digital Input Conditioning |
|---|---|
Use Scenario: Driving status LEDs from 3.3 V microcontroller GPIO pins with current limiting handled internally. IC Role / Device Role: Single-transistor current sink replacing discrete BJT + two-resistor solution. Use Value: Reduces footprint by 40% and eliminates resistor placement error risk while maintaining 5 mA LED current accuracy within ±8%. |
Use Scenario: Level-shifting and noise-immune conditioning of push-button or switch signals into FPGA or MCU interrupt inputs. IC Role / Device Role: Digital interface buffer with built-in pull-up via R2, eliminating external 10 kΩ resistor. Use Value: Ensures VI(off) ≤ −0.6 V guarantees solid logic-low recognition even with 100 mV of EMI-induced noise on the line. |
| Low-Power Load Switching | BC857 Drop-in Replacement |
Use Scenario: Enabling/disabling 5 V sensor modules or small solenoids (<100 mA) using 1.8 V or 3.3 V logic control. IC Role / Device Role: High-side switch controller with integrated bias, configured as low-side sink in most implementations. Use Value: Achieves VCE(sat) ≤ −100 mV at IC = −50 mA, limiting power dissipation to <5 mW and avoiding thermal throttling. |
Use Scenario: Direct replacement for BC857B in existing designs seeking reduced component count and improved manufacturability. IC Role / Device Role: Pin-compatible functional substitute offering identical VCEO, IC, and hFE specs in smaller DFN package. Use Value: Maintains legacy circuit behavior while reducing PCB area by 65% and enabling AOI-based assembly verification. |
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 |
|---|---|---|---|
| PDTC123JQC | NPN counterpart with same R1/R2 values (2.2 kΩ/47 kΩ), VCEO = 50 V, IC = 100 mA, but opposite polarity and complementary pinout (input = pin 1, collector = pin 2). | Requires circuit inversion: suitable only where NPN sinking is acceptable instead of PNP sourcing/sinking topology. | Select when redesign permits NPN logic interface and board layout allows pinout reassignment. |
| PDTA143XQC | Same package and RET architecture but with R1 = 4.7 kΩ / R2 = 10 kΩ, resulting in lower R2/R1 ratio (2.13) and higher hFE sensitivity to base drive variation. | Better suited for high-gain, low-drive scenarios (e.g., weak GPIOs); less tolerant of input voltage drift than PDTA123JQC's 21:1 ratio. | Prefer when driving from low-current sources (<100 µA) or when tighter VI(on)/VI(off) margins are required. |
Compared with PDTC123JQC, PDTA123JQC provides native PNP logic compatibility without signal inversion; compared with PDTA143XQC, its 21× R2/R1 ratio delivers superior noise immunity and consistent saturation across wider input voltage ranges.

FAQ
What is the maximum continuous collector current for PDTA123JQC?
The maximum continuous collector current is −100 mA at Tamb ≤ 25 °C on a standard FR4 PCB with 70 µm copper. Derating begins above 25 °C per Figure 1, reaching ~60 mA at 85 °C ambient. This rating assumes proper thermal land pattern per Figure 37 and no localized hot spots.
Does PDTA123JQC require an external pull-up resistor for digital input applications?
No. The internal 47 kΩ resistor (R2) connects base to emitter (pin 2/GND), forming a built-in pull-down that ensures defined off-state behavior. When used as a digital input conditioner, no external pull-up is needed-the device inherently pulls the input low when inactive and switches high only when driven.
Can PDTA123JQC be used in place of a standard BC857 transistor?
Yes-as a functional drop-in replacement in most digital switching roles. It matches BC857B's VCEO (−50 V), IC (−100 mA), and hFE (100–250), but integrates bias resistors and uses a smaller DFN package. Layout adaptation is required due to different pinout and footprint.
What is the significance of side-wettable flanks in the SOT8009 package?
Side-wettable flanks expose copper on the vertical edges of all three terminals, allowing automated optical inspection (AOI) systems to verify solder joint formation and wetting quality without X-ray imaging. This improves first-pass yield and reduces post-reflow rework in high-volume SMT lines.
