Product details
Overview
PDTC123JQB-Q from Nexperia is a 50 V, 100 mA NPN resistor-equipped transistor (RET) in a DFN1110D-3 (SOT8015) 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 PDTC123JQB-Q datasheet, PDTC123JQB-Q pinout, PDTC123JQB-Q application, or PDTC123JQB-Q equivalent, this part serves as a space-optimized, AOI-compatible replacement for BC847-Q series transistors in load switching and IC input control circuits where reduced component count and 0.5 mm profile are critical.
Technical Context
This RET implements an integrated NPN bipolar junction transistor with two monolithically embedded silicon resistors: R1 connects base to input terminal, R2 connects base to emitter. The internal topology eliminates external biasing components while maintaining predictable DC current gain (hFE = 100 typ.) and low saturation voltage under defined drive conditions.
Designed for digital switching, it operates with VI(on) = 0.75–1.1 V at IC = 5 mA and VI(off) = 0.5–0.6 V, enabling reliable logic-level interfacing. Its thermal resistance Rth(j-a) is 298 K/W on 70 µm FR4 PCB, supporting continuous 100 mA output within 150 °C junction limit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; defines safe operating range in switching circuits. |
| IO | 100 mA - Continuous output current capability; supports driving moderate loads like LEDs or small relays. |
| R1 / R2 | 2.2 kΩ / 47 kΩ - Pre-biased resistor values set base current and ensure stable turn-on without external components. |
| hFE | 100 (typ.) at VCE = 5 V, IC = 10 mA - Predictable DC current gain enables accurate load current estimation in design. |
| VCE(sat) | ≤100 mV at IC = 5 mA, IB = 0.25 mA - Low saturation voltage minimizes power loss and heat generation during conduction. |
| AEC-Q101 | Qualified - Meets automotive stress test requirements for reliability in under-hood and infotainment systems. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Applications
| Automotive Body Control Module | Industrial PLC Input Stage |
|---|---|
Use Scenario: Switching 12 V indicator LEDs and solenoid drivers in door modules and lighting controllers. IC Role / Device Role / Timing Role: NPN switch controlling current path from battery rail to load; operates in saturated on/off mode. Use Value: AEC-Q101 qualification ensures long-term reliability across -40 °C to +125 °C ambient, while low VCE(sat) reduces thermal load in sealed enclosures. |
Use Scenario: Level-shifting and isolating 24 V field signals into 3.3 V/5 V microcontroller GPIO inputs. IC Role / Device Role / Timing Role: Digital input buffer providing current-limited, noise-immune signal conditioning. Use Value: Built-in R1/R2 sets precise input threshold (VI(on)/VI(off)), eliminating calibration and reducing external component dependency. |
| Consumer Appliance UI Panel | Medical Diagnostic Equipment |
Use Scenario: Driving backlight segments and tactile feedback actuators in smart home control panels. IC Role / Device Role / Timing Role: Low-power load switch activated by MCU GPIO pins with minimal external circuitry. Use Value: 100 mA rating and 0.5 mm height enable compact, fanless designs; AOI-compatible package supports high-volume SMT assembly. |
Use Scenario: Isolating sensor excitation signals and relay control paths in portable diagnostic devices. IC Role / Device Role / Timing Role: Safe, low-leakage switching element for patient-connected subsystems requiring predictable off-state behavior. Use Value: ICEO ≤ 5 µA at 150 °C ensures minimal standby current drift over lifetime, supporting battery-operated operation. |
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 |
|---|---|---|---|
| PDTC143XQB-Q | R1 = 4.7 kΩ, R2 = 10 kΩ, hFE = 50, VI(on) = 1.5–2.5 V | Better suited for higher-VCC logic interfaces (e.g., 5 V CMOS), lower gain requires stronger drive. | Select when interfacing with 5 V microcontrollers and lower base current is acceptable. |
| BC847B-Q | Discrete NPN BJT (no built-in resistors), hFE = 200–450, requires external bias network. | Offers higher gain and flexibility but increases component count and layout complexity. | Choose when precise gain tuning or variable biasing is required beyond fixed RET configurations. |
Compared with PDTC143XQB-Q, PDTC123JQB-Q provides higher hFE and tighter VI(on) for 3.3 V logic, while BC847B-Q trades integration for design flexibility-making PDTC123JQB-Q optimal for cost-sensitive, space-constrained digital switching where AEC-Q101 compliance is mandatory.

FAQ
What is the maximum continuous collector current for PDTC123JQB-Q?
The maximum continuous collector current is 100 mA at Tamb ≤ 25 °C on a standard FR4 PCB with 70 µm copper. Derating applies above 25 °C per Figure 1: at 85 °C ambient, maximum sustainable current drops to approximately 65 mA due to thermal limits.
Can PDTC123JQB-Q replace BC847B-Q directly in existing designs?
No direct drop-in replacement: PDTC123JQB-Q integrates base resistors and uses a 3-pin DFN package, whereas BC847B-Q is a 3-pin SOT23 discrete BJT requiring external biasing. Layout and schematic changes are needed to remove external resistors and adapt footprint.
Is the DFN1110D-3 package compatible with standard reflow profiles?
Yes-the SOT8015 package is qualified for JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles. Recommended stencil thickness is 0.1 mm, and solder land pattern matches IPC-7351B density level 'N' for reliable wetting of side-wettable flanks.
What is the typical off-state input voltage (VI(off)) and why does it matter?
VI(off) is 0.5–0.6 V at VCE = 5 V and IC = 100 µA. This parameter defines the maximum input voltage at which the device remains reliably off-critical for noise immunity in industrial environments where signal lines may experience coupling or leakage currents.
