Product details
Overview
PDTA123YQB-Q from Nexperia is a 50 V, 100 mA PNP resistor-equipped transistor (RET) in a DFN1110D-3 (SOT8015) leadless package with side-wettable flanks. It integrates R1 = 2.2 kΩ and R2 = 10 kΩ bias resistors, functions as a digital switch for IC input control or load switching, and is AEC-Q101 qualified for automotive use.
For engineers reviewing the PDTA123YQB-Q datasheet, PDTA123YQB-Q pinout, PDTA123YQB-Q application, or PDTA123YQB-Q equivalent, this part serves as a space- and cost-optimized replacement for BC847-series discrete transistors in low-power digital logic interfacing and automotive body electronics where simplified BOM and AOI-compatible solder joints are required.
Technical Context
This PNP RET uses an integrated dual-resistor network (R1 to base, R2 from base to emitter) to provide fixed-current biasing, eliminating external base resistors. Its open-base VCEO = −50 V and IO = −100 mA rating support robust switching in 12 V/24 V automotive domains.
The DFN1110D-3 package enables ultra-low profile mounting (0.48 mm height) and supports Automatic Optical Inspection via side-wettable flanks. Thermal resistance Rth(j-a) is 298 K/W on 70 μm copper FR4, enabling stable operation up to Tj = 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum collector-emitter voltage before breakdown; supports 24 V automotive rail with margin. |
| IO | −100 mA - Continuous output current capability; sufficient for driving LED indicators or small relays. |
| R1 | 2.2 kΩ - Integrated input bias resistor; sets base current without external component. |
| R2/R1 ratio | 4.5 - Fixed internal feedback ratio; ensures stable saturation and predictable turn-off behavior. |
| VCE(sat) | −150 mV @ IC = −10 mA, IB = −0.5 mA - Low saturation voltage minimizes power loss in switching mode. |
| hFE | 35 @ VCE = −5 V, IC = −5 mA - DC current gain optimized for digital on/off operation, not linear amplification. |
| fT | 180 MHz - Transition frequency of internal transistor; ensures fast edge response in digital switching. |
Pinout & Package
Package: DFN1110D-3 (SOT8015), 1.1 mm × 1.0 mm × 0.48 mm body, side-wettable flanks, 0.65 mm pitch, leadless surface-mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts TTL/CMOS logic-level drive directly. |
| 2 | Ground (emitter) | Emitter terminal tied to system ground; provides return path for load current. |
| 3 | Output (collector) | Switched high-side output node; connects to load (e.g., LED anode or relay coil). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias network | R1 = 2.2 kΩ + R2 = 10 kΩ eliminates two external resistors and reduces PCB footprint by >30%. |
| AEC-Q101 qualification | Qualified per stress test standard for discrete semiconductors; validated for under-hood automotive environments. |
| Side-wettable flanks | Enables reliable Automated Optical Inspection (AOI) of solder joints without X-ray, improving manufacturing yield. |
| Ultra-thin profile | 0.48 mm max height supports ultra-slim modules in space-constrained infotainment and ADAS ECUs. |
Applications
| Automotive Interior Lighting | Body Control Module Inputs |
|---|---|
|
Use Scenario: Driving LED map lights and door courtesy lamps in 12 V vehicle systems. IC Role / Device Role / Timing Role: PNP switch controlling current path from battery rail to LED cathode. Use Value: −150 mV VCE(sat) limits power dissipation to <1.5 mW at 10 mA, enabling thermally stable operation without heatsinking. |
Use Scenario: Level-shifting and debouncing push-button signals into microcontroller GPIOs. IC Role / Device Role / Timing Role: Digital buffer isolating noisy mechanical switch inputs from sensitive MCU pins. Use Value: Built-in R1/R2 network ensures consistent turn-on threshold (VI(on) = −1.15 V typ.) across temperature (−40 °C to +100 °C). |
| Smart Sensor Interface | Industrial PLC Input Stage |
|
Use Scenario: Interfacing Hall-effect or reed-switch sensors to 3.3 V logic in automotive seat position modules. IC Role / Device Role / Timing Role: Signal conditioner converting open-collector sensor outputs to clean CMOS-compatible levels. Use Value: VI(off) = −0.75 V ensures reliable turn-off even with leakage currents up to −100 nA at VCB = −50 V. |
Use Scenario: Isolating 24 V industrial field inputs to 5 V logic in programmable logic controller (PLC) input cards. IC Role / Device Role / Timing Role: High-voltage tolerant digital switch providing galvanic separation between field and logic domains. Use Value: VCEO = −50 V and Tamb = −55 °C to +150 °C rating ensure reliability in harsh factory-floor environments. |
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 |
|---|---|---|---|
| PDTC123YQB-Q | NPN complement with identical R1/R2 values and package; VCEO = +50 V, IO = +100 mA. | Used for low-side switching; requires inverted logic drive and different load connection topology. | Select when sinking current (e.g., driving N-channel MOSFET gate or grounding sensor output). |
| BC847B,115 | Discrete PNP BJT without integrated resistors; hFE = 200–450; requires two external base resistors. | Offers higher gain and wider VCE linear range but increases BOM count and layout area. | Choose only if precise analog biasing or adjustable gain is required; not recommended for simple on/off logic. |
Compared with PDTC123YQB-Q, this part enables high-side switching with direct logic compatibility, while BC847B adds design flexibility at the cost of component count and assembly complexity-making PDTA123YQB-Q optimal for cost- and space-sensitive digital interface applications.

FAQ
What is the maximum ambient temperature for continuous operation?
The PDTA123YQB-Q is rated for continuous operation from −55 °C to +150 °C ambient temperature. At full 100 mA load, derating begins above +25 °C per the power derating curve: on 70 μm FR4, total power dissipation drops to 340 mW at +75 °C and 0 mW at +150 °C.
Can this device replace a standard BC847 in existing designs?
Yes-PDTA123YQB-Q is a drop-in functional replacement for BC847-series PNP transistors in digital switching applications. Its integrated R1/R2 network eliminates two external resistors, maintains identical pinout compatibility in SOT23 footprints (with adapter layout), and delivers matching VCE(sat) and switching speed.
Is the DFN1110D-3 package compatible with standard reflow profiles?
Yes-the DFN1110D-3 package is qualified for JEDEC J-STD-020D-compliant lead-free reflow. Recommended stencil thickness is 0.1 mm; solder paste volume targets 0.34 mm² per pad. Side-wettable flanks enable post-reflow AOI verification without X-ray inspection.
Does the R2/R1 ratio affect switching speed or noise immunity?
Yes-the fixed R2/R1 = 4.5 ratio enhances noise immunity by providing strong base-emitter feedback during turn-off, reducing susceptibility to EMI-induced false triggering. It also stabilizes switching time: ton and toff remain within ±15% over −40 °C to +100 °C due to matched resistor TC.
