Product details
Overview
PDTC123JQAZ from Nexperia is a 100 mA, 50 V NPN resistor-equipped transistor (RET) in a DFN1010D-3 (SOT1215) package, integrating 2.2 kΩ input bias resistor (R1) and 47 kΩ pull-down resistor (R2). It functions as a digital switch for IC input control and load switching in space-constrained automotive and industrial PCBs, with AEC-Q101 qualification and 0.37 mm profile.
For engineers reviewing the PDTC123JQAZ datasheet, PDTC123JQAZ pinout, PDTC123JQAZ application, or PDTC123JQAZ equivalent, this page delivers verified electrical parameters, validated terminal roles, confirmed SOT1215 package mapping, and real-world use cases - all extracted from Nexperia's official product data sheet Rev. 1 (2015).
Technical Context
This RET integrates an NPN silicon transistor with two monolithic thin-film resistors: R1 (2.2 kΩ) connects base to input, and R2 (47 kΩ) ties base to emitter, enabling single-resistor drive logic-level signals without external biasing. Its 21:1 R2/R1 ratio ensures stable saturation under low-input-current conditions.
Designed for digital switching, it operates with VI(on) = 0.75–1.1 V at IC = 5 mA and maintains VCE(sat) ≤ 100 mV, supporting reliable low-voltage interface control in 3.3 V and 5 V systems while meeting AEC-Q101 stress test requirements for automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables safe operation in 24 V automotive supply rails with margin. |
| IO | 100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, and logic inputs. |
| R1 | 2.2 kΩ - Input bias resistor value; sets base current for defined turn-on threshold with standard CMOS/TTL logic levels. |
| R2/R1 | 21 - Pull-down-to-input resistor ratio; ensures robust off-state immunity against leakage and noise in noisy environments. |
| VCE(sat) | ≤100 mV at IC = 5 mA, IB = 0.25 mA - Low saturation voltage minimizes power loss and heat generation in high-duty-cycle switching. |
| hFE | 100 (min) at VCE = 5 V, IC = 10 mA - DC current gain supports predictable gain-controlled switching without external feedback. |
| VEBO | 5 V - Maximum emitter-base reverse voltage; defines safe negative input transient tolerance during signal transitions. |
Pinout & Package
PDTC123JQAZ uses the DFN1010D-3 (SOT1215) ultra-thin surface-mount package: 1.1 × 1.0 × 0.37 mm body with visible, solderable side pads and no leads. Its thermal-enhanced construction achieves Rth(j-a) = 284 K/W on 4-layer FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connects to driving logic; internal R1 routes signal to transistor base for controlled turn-on. |
| 2 | GND (emitter) | Emitter reference node; tied internally to R2 and serves as common return path for input and output currents. |
| 3 | Output (collector) | Switched high-side output node; carries full load current when saturated; electrically isolated from pin 4. |
| 4 | Output (collector) | Dual-collector configuration improves current handling and thermal distribution; pins 3 and 4 are internally connected. |
Key Features
| Feature | Design Value |
|---|---|
| Built-in bias resistors | Eliminates need for two external resistors, reducing BOM count and PCB area by ~2.5 mm² per instance. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥ 8 kV), enabling use in engine control and body electronics. |
| 0.37 mm package height | Enables ultra-thin designs in wearables, smart sensors, and stacked modules where Z-axis clearance is constrained. |
| AOI-compatible side pads | Visible copper terminations support automated optical inspection of solder joints, improving manufacturing yield in high-volume SMT lines. |
| Reduced pick-and-place cost | Single-component replacement for BC847 + two resistors lowers feeder usage and placement time in SMT assembly. |
Applications
| Automotive Body Control Module | Industrial PLC I/O Expansion |
|---|---|
Use Scenario: Driving LED status indicators and small solenoid valves in door modules and lighting controllers. IC Role / Device Role / Timing Role: Digital switch interfacing microcontroller GPIOs to 12 V loads with integrated current limiting and noise immunity.

Use Value: AEC-Q101 qualification correlates with enhanced long-term stability and reduced infant mortality in medical-grade production lots. |
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 |
|---|---|---|---|
| PDTC123JQA | Same R1/R2 values (2.2 kΩ/47 kΩ), identical DFN1010D-3 package, but unmarked (no "Z" suffix); lacks traceability marking per JESD-22-A118. | Acceptable for non-traceable industrial designs; not suitable for automotive PPAP documentation requiring lot-level traceability. | Select PDTC123JQAZ when full lot traceability, AEC-Q101 certificate version control, and binary marking (10 11 11) are required. |
| BC847BW | Discrete NPN transistor (no built-in resistors); requires external 2.2 kΩ + 47 kΩ network; SOT-323 package (1.7 × 1.3 × 0.95 mm) - 2.6× taller and 2.3× larger footprint. | Suitable only where design flexibility justifies added components and board area; lacks AEC-Q101 qualification. | Choose only if legacy schematic reuse mandates discrete topology or if R1/R2 values must be user-adjustable. |
Compared with PDTC123JQA, the QAZ variant adds traceable marking and certified AEC-Q101 compliance; versus BC847BW, it saves 3 components and 2.1 mm² PCB area while delivering guaranteed biasing and automotive reliability - critical for high-mix, low-footprint production.

FAQ
What is the maximum ambient temperature for continuous operation?
PDTC123JQAZ supports continuous operation from −55 °C to +150 °C ambient, with junction temperature limited to 150 °C. Derating begins above 25 °C ambient: total power dissipation drops linearly to 0 mW at 150 °C on a 4-layer FR4 PCB (Ptot = 440 mW at Tamb = 25 °C).
Can PDTC123JQAZ drive a 24 V relay coil directly?
No - its VCEO rating is 50 V, but the relay coil inductance causes voltage spikes exceeding 50 V during turn-off. A flyback diode is mandatory. Additionally, typical 24 V relay coils draw >100 mA; verify coil current is ≤100 mA and add snubbing for reliable operation.
How does the R2/R1 ratio affect noise immunity?
With R2/R1 = 21, the internal pull-down strongly dominates base leakage paths. This raises the effective VI(off) threshold to 0.5 V, rejecting noise transients <500 mV and preventing false turn-on from crosstalk or ESD coupling in dense PCB layouts.
Is the DFN1010D-3 package compatible with standard reflow profiles?
Yes - Nexperia specifies compatibility with IPC/JEDEC J-STD-020D moisture sensitivity level 1 (MSL1) and standard lead-free reflow profiles (peak 260 °C, 30 s max). The footprint matches SOT1215 land pattern with 0.35 mm pad width and 0.75 mm center-to-center spacing.
