Product details
Overview
PDTC123JQC-Q from Nexperia is a 50 V, 100 mA NPN resistor-equipped transistor (RET) in a DFN1412D-3 (SOT8009) leadless package with side-wettable flanks. It integrates R1 = 2.2 kΩ and R2 = 47 kΩ bias resistors, delivers hFE = 100 at IC = 10 mA, achieves VCE(sat) ≤ 100 mV at IC = 5 mA/IB = 0.25 mA, and is AEC-Q101 qualified for automotive digital switching applications.
For engineers reviewing the PDTC123JQC-Q datasheet, PDTC123JQC-Q pinout, PDTC123JQC-Q application, or PDTC123JQC-Q equivalent, this RET simplifies load switching and IC input control by eliminating external base resistors, reducing BOM count and PCB area in space-constrained automotive and industrial digital circuits.
Technical Context
This NPN RET uses an integrated bipolar junction transistor with two monolithically embedded silicon resistors: R1 connects base to input, R2 connects base to emitter. The 2.2 kΩ / 47 kΩ ratio sets a fixed current gain bias network optimized for digital on/off operation rather than linear amplification.
Designed for low-voltage logic-level drive (VI(on) = 0.75–1.1 V), it ensures reliable saturation with microampere-level input current (II1 = 90 µA typical), while maintaining VI(off) ≤ 0.6 V to guarantee cutoff under noise margin conditions - critical for robust digital interface behavior.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive rail switching with safety margin |
| IO | 100 mA - Continuous output current capability; sufficient for driving LEDs, small relays, or logic inputs |
| R1 / R2 | 2.2 kΩ / 47 kΩ - Fixed internal bias network; eliminates need for two external resistors and reduces layout complexity |
| hFE | 100 (typ.) at VCE = 5 V, IC = 10 mA - Confirmed DC current gain enabling predictable saturation with minimal base drive |
| VCE(sat) | ≤ 100 mV at IC = 5 mA, IB = 0.25 mA - Ultra-low saturation voltage minimizes power loss and self-heating in switching mode |
| AEC-Q101 | Qualified - Meets stress test requirements for discrete semiconductors in automotive environments (−40 °C to +150 °C) |
Pinout & Package
DFN1412D-3 (SOT8009) ultra-small leadless package: 1.4 mm × 1.2 mm × 0.48 mm body height, 0.8 mm pitch, side-wettable flanks for AOI-compatible solder joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | I (input) | Base connection via internal R1; accepts logic-level voltage directly without external pull-up or current-limiting resistor |
| 2 | GND (emitter) | Emitter tied to system ground; also connects to R2, forming internal voltage divider for stable biasing |
| 3 | O (output) | Collector output node; switches loads between VCC and this terminal; rated for 50 V and 100 mA continuous |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | Eliminates two external components, reducing PCB footprint and assembly cost in high-volume digital control designs |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints on bottom-terminated terminals - essential for automotive manufacturing traceability |
| Low profile (0.48 mm) | Supports ultra-thin end equipment such as ADAS sensors and compact infotainment modules where Z-height is constrained |
| Automotive qualification | AEC-Q101 compliance confirms reliability under thermal cycling, humidity, and mechanical shock conditions required for under-hood use |
Applications
| Automotive Body Control Module | Industrial PLC Input Interface |
|---|---|
Use Scenario: Switching 12 V indicator LEDs and small solenoids in door module PCBs. IC Role / Device Role / Timing Role: NPN switch controlling current path from battery rail to load; operates in saturated on/off state with <1 µs turn-on delay. Use Value: Reduces component count per channel by two resistors, cutting BOM cost and improving long-term reliability over discrete resistor-transistor combinations. |
Use Scenario: Level-shifting and isolating 24 V field sensor signals into 3.3 V microcontroller GPIOs. IC Role / Device Role / Timing Role: Digital input buffer providing galvanic separation and noise immunity; driven by open-collector sensor outputs. Use Value: Built-in resistor network ensures consistent threshold behavior across temperature (−40 °C to +125 °C), eliminating calibration drift in factory automation systems. |
| Consumer Appliance Control Board | Medical Diagnostic Device Logic Interface |
Use Scenario: Driving buzzer and status LED arrays in smart HVAC controllers. IC Role / Device Role / Timing Role: Low-side load switch activated by MCU GPIO; handles repetitive 100 ms on/off cycles without thermal derating. Use Value: 100 mV VCE(sat) limits power dissipation to <5 mW per channel, enabling dense placement on thermally restricted FR4 boards. |
Use Scenario: Enabling/disabling analog front-end signal paths in portable ultrasound units. IC Role / Device Role / Timing Role: Precision enable gate for analog switches; requires fast, clean transitions and minimal leakage (<180 µA IEBO). Use Value: Guaranteed VI(off) ≤ 0.6 V ensures sub-µA standby current, extending battery life in Class II medical devices with strict energy budgets. |
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 |
|---|---|---|---|
| PDTC123EKQC-Q | R1 = 2.2 kΩ, R2 = 47 kΩ, same package, but hFE = 300 (min) vs. 100 (typ) - higher gain variant | Better suited for low-drive microcontrollers (e.g., 1.8 V I/O) requiring lower input current | Select when driving from ultra-low-current sources; verify VI(on) compatibility at target VCC |
| BC847B-Q | Discrete NPN transistor (no built-in resistors); requires external R1/R2; same SOT323 package but larger footprint | Offers design flexibility for adjustable gain or analog operation, but increases BOM and layout effort | Choose only if variable bias or linear amplification is needed; otherwise RET offers superior integration |
Compared with PDTC123EKQC-Q, PDTC123JQC-Q provides tighter hFE control for deterministic digital switching, while BC847B-Q trades integration for configurability - making PDTC123JQC-Q optimal for cost-sensitive, high-reliability digital interface roles where fixed gain suffices.

FAQ
What is the maximum operating temperature for PDTC123JQC-Q?
The junction temperature limit is 150 °C, and the ambient operating range is −55 °C to +150 °C. Thermal resistance Rth(j-a) is 278 K/W on a 70 µm copper FR4 PCB, allowing ~360 mW power dissipation at 25 °C ambient before derating begins - sufficient for 100 mA switching at low VCE(sat).
Can PDTC123JQC-Q replace BC847B-Q without circuit modification?
No - PDTC123JQC-Q has integrated base resistors and is optimized for direct logic-level drive, whereas BC847B-Q requires external biasing. Replacing BC847B-Q with PDTC123JQC-Q eliminates two resistors but may require adjusting input voltage thresholds due to different VI(on)/VI(off) characteristics and fixed gain behavior.
Is PDTC123JQC-Q suitable for PWM dimming of LEDs?
Yes - its 100 mA rating, 100 mV VCE(sat), and 230 MHz fT support PWM frequencies up to several hundred kHz. However, thermal performance must be verified at target duty cycle and ambient temperature, as power dissipation scales with average current and VCE(sat).
Does the DFN1412D-3 package support reflow soldering with standard stencil thickness?
Yes - the recommended stencil thickness is 0.1 mm, and the footprint (1.4 mm × 1.2 mm pad, 0.8 mm pitch) is defined in Nexperia's SOT8009 reflow guidelines. Side-wettable flanks ensure solder fillet visibility for post-reflow AOI, meeting IPC-A-610 Class 2/3 requirements.
