Product details
Overview
PDTC123YQB-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, featuring integrated R1 = 2.2 kΩ and R2 = 10 kΩ bias resistors. It serves as a single-chip digital switch for IC input control and load switching in space-constrained automotive and industrial PCBs.
For engineers reviewing the PDTC123YQB-Q datasheet, PDTC123YQB-Q pinout, PDTC123YQB-Q application, or PDTC123YQB-Q equivalent, this part offers AEC-Q101 qualification, AOI-compatible solder joints, and direct replacement capability for BC847-based digital interface circuits requiring reduced BOM count and simplified drive logic.
Technical Context
This RET integrates an NPN transistor with two monolithic thin-film resistors: R1 (2.2 kΩ) connected between input and base, and R2 (10 kΩ) from base to emitter, enabling single-resistor drive and eliminating external bias networks. Its 0.5 mm profile and side-wettable flanks support automated optical inspection and high-density reflow assembly.
The device delivers guaranteed hFE ≥ 35 at IC = 5 mA and VCE = 5 V, with VCEsat ≤ 150 mV at IC = 10 mA/IB = 0.5 mA, and operates across −55 °C to +150 °C ambient. It meets AEC-Q101 stress test requirements for automotive discrete semiconductors, including HTGB, HTRB, and temperature cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IO | 100 mA - Continuous output current rating; supports driving LED indicators, small relays, or logic inputs. |
| R1 | 2.2 kΩ - Input bias resistor value; sets base current for predictable turn-on with standard CMOS/TTL logic levels. |
| R2/R1 ratio | 4.5 (typ) - Ensures stable saturation and low leakage by fixing base-emitter feedback proportion. |
| VCEsat | ≤150 mV at IC = 10 mA - Low saturation voltage minimizes power loss and heat generation in switching mode. |
| fT | 230 MHz - Transition frequency of internal transistor; supports fast digital switching up to ~10 MHz edge rates. |
| Package | DFN1110D-3 (SOT8015) - 1.1 mm × 1.0 mm × 0.48 mm ultra-thin leadless package with side-wettable flanks for AOI. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connects to driving logic; current flows through R1 into base node for transistor activation. |
| 2 | Ground (emitter) | Common reference terminal; ties emitter to system ground and provides return path for R2. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode or relay coil) referenced to VCC. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated R1 + R2 bias network | Eliminates two external resistors, reducing PCB area and pick-and-place steps in high-volume SMT lines. |
| AEC-Q101 qualified | Validated for automotive underhood and cabin applications per stress test standards including HTGB and HTRB. |
| Side-wettable flanks | Enables automated optical inspection of solder fillets without X-ray, improving process yield and traceability. |
| 0.5 mm max height | Supports ultra-low-profile designs such as camera modules, ADAS sensors, and compact ECUs where Z-height is constrained. |

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 |
|---|---|---|---|
| BC847B,115 | Discrete NPN transistor without built-in resistors; requires external RB and RBE network. | Higher BOM count and layout complexity; not AOI-optimized or AEC-Q101 qualified. | Select when fine-tuned biasing or higher hFE variability tolerance is required. |
| PDTA123YQB-Q | PNP complement with identical R1/R2 values and DFN1110D-3 package; VECO = 50 V, IO = −100 mA. | Used for high-side switching or inverted logic interfaces; shares footprint and thermal profile. | Select for complementary push-pull output stages or dual-rail digital interface designs. |
Compared with BC847B,115, PDTC123YQB-Q reduces design effort and improves manufacturability via integrated biasing and AOI support; compared with PDTA123YQB-Q, it provides NPN polarity for low-side switching with identical thermal and mechanical behavior.

FAQ
What is the maximum operating temperature for PDTC123YQB-Q?
The junction temperature limit is 150 °C, and the ambient operating range is −55 °C to +150 °C. Derated power dissipation must be observed per Figure 1 in the datasheet: at 100 °C ambient, Ptot drops to ~250 mW on standard FR4 with 35 μm copper.
Can PDTC123YQB-Q replace BC847 in existing designs?
Yes, as a drop-in functional replacement in digital switching roles-provided the circuit uses standard TTL/CMOS logic drive and does not require adjustable bias. The integrated R1/R2 network eliminates two external resistors, but layout must accommodate the DFN1110D-3 footprint and side-wettable flanks.
Is PDTC123YQB-Q suitable for high-frequency switching?
Its fT is 230 MHz, supporting clean digital edges up to ~10 MHz. However, it is optimized for DC–1 MHz switching-not RF amplification. For >10 MHz PWM, verify VCEsat stability and switching losses using the transient thermal impedance curves in Figures 2 and 3.
Does PDTC123YQB-Q require special PCB layout considerations?
Yes: use the exact SOT8015 footprint from Figure 12, including 0.65 mm pitch, 0.34 mm pad width, and 0.1 mm stencil thickness. Thermal relief on Pin 2 (GND) is critical-minimum 0.44 mm² copper area recommended per datasheet Section 13 for 420 mW dissipation.
