Product details
Overview
PDTA123JQC-Q from Nexperia is a 50 V, 100 mA PNP resistor-equipped transistor (RET) in a DFN1412D-3 (SOT8009) leadless SMD package with side-wettable flanks. It integrates 2.2 kΩ input bias resistor (R1) and 47 kΩ feedback resistor (R2), delivers hFE = 100 at IC = −5 mA, VCE(sat) ≤ −100 mV, and is AEC-Q101 qualified for automotive digital switching.
For engineers reviewing the PDTA123JQC-Q datasheet, PDTA123JQC-Q pinout, PDTA123JQC-Q application, or PDTA123JQC-Q equivalent, this RET simplifies load switching and IC input control by eliminating external base resistors while supporting AOI-compatible reflow assembly in space-constrained automotive and industrial PCBs.
Technical Context
This PNP RET uses an integrated bipolar junction transistor with on-chip R1–R2 resistor network configured for fixed-current biasing. Its input stage accepts logic-level signals (VI(on) = −1.1 to −0.75 V at IC = −5 mA), enabling direct interface with 3.3 V/5 V microcontrollers without level-shifting.
The device operates with open-base VCEO = −50 V and supports continuous IO = −100 mA output current. Thermal resistance Rth(j-a) is 278 K/W on 70 µm FR4 PCB, and its 0.48 mm profile enables ultra-thin board designs compliant with modern automotive ECU form factors.
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 capability; sufficient for driving LEDs, relays, and logic inputs. |
| R1 / R2 | 2.2 kΩ / 47 kΩ - Fixed internal bias network; eliminates two external resistors and reduces BOM count. |
| hFE | 100 (typ.) at VCE = −5 V, IC = −5 mA - Predictable DC gain ensures stable saturation under defined drive conditions. |
| VCE(sat) | ≤ −100 mV - Low saturation voltage minimizes power loss and heat generation in switching applications. |
| Package | DFN1412D-3 (SOT8009) - 1.4 × 1.2 × 0.48 mm leadless package with side-wettable flanks for automated optical solder-joint inspection. |
Pinout & Package
DFN1412D-3 (SOT8009) is a 3-terminal, leadless plastic package with 0.8 mm pitch, 1.4 mm × 1.2 mm body, and 0.48 mm height. Side-wettable flanks support reliable AOI-based solder-joint verification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Accepts logic-level control signal; internally connected to R1 top node and transistor base. |
| 2 | GND (emitter) | Emitter terminal tied to system ground; serves as common reference for input and output paths. |
| 3 | Output (collector) | Switched high-side output node; sinks current from load to emitter (GND) when active. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Qualified for automotive-grade reliability per stress test requirements; suitable for engine control, body electronics, and ADAS modules. |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray; improves manufacturing yield in high-volume SMT lines. |
| Ultra-low profile | 0.48 mm max height - allows placement beneath connectors or in stacked-board assemblies where Z-space is constrained. |
| Reduced component count | Integrates R1 and R2; replaces discrete PNP + two resistors, cutting pick-and-place cycles and PCB real estate by ≥3 parts. |
Applications
| Automotive Body Control Module | Industrial PLC Input Stage |
|---|---|
Use Scenario: Switching 12 V indicator LEDs and small solenoids in door modules and lighting controllers. IC Role / Device Role / Timing Role: High-side switch controlling current path from battery rail to grounded loads. Use Value: −100 mV VCE(sat) limits power dissipation to <10 mW at 100 mA, reducing thermal design burden in sealed enclosures. |
Use Scenario: Level-shifting and isolating 24 V field sensor signals into 3.3 V microcontroller GPIO pins. IC Role / Device Role / Timing Role: Digital input buffer providing galvanic separation and overvoltage protection via built-in resistor network. Use Value: VI(off) = −0.6 V ensures robust noise immunity against transients up to ±12 V on input line without external clamping. |
| Consumer Appliance Power Sequencing | Medical Diagnostic Equipment Interface |
Use Scenario: Enabling sequential power-up of subsystems (e.g., display backlight, motor driver, comms IC) in smart home hubs. IC Role / Device Role / Timing Role: Controlled enable switch activated by MCU GPIO to gate downstream 5 V/3.3 V rails. Use Value: R1/R2 ratio of 21 ensures predictable turn-on threshold and eliminates timing skew from discrete resistor tolerances. |
Use Scenario: Isolating low-power sensor excitation circuits from main controller in portable diagnostic devices. IC Role / Device Role / Timing Role: Precision current-source switch for driving resistive temperature sensors (RTDs) or strain gauges. Use Value: hFE = 100 with tight distribution ensures consistent current sourcing accuracy across production batches. |
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 |
|---|---|---|---|
| PDTC123JQC-Q | NPN complement with identical R1/R2 values (2.2 kΩ/47 kΩ), same package and AEC-Q101 rating. | Requires inverted logic drive and low-side switching topology instead of high-side. | Select when load is grounded and controller can sink current; preserves layout compatibility. |
| BC857B-Q | Discrete PNP transistor (no integrated resistors); requires external R1/R2; same SOT323 package but no side-wettable flanks. | Lacks AOI support and increases BOM count; higher assembly cost and footprint area. | Choose only if resistor values must be user-adjustable or if legacy SOT323 footprint reuse is mandatory. |
Compared with PDTC123JQC-Q, PDTA123JQC-Q enables high-side switching without logic inversion; compared with BC857B-Q, it reduces PCB area by 35% and eliminates two passives while enabling AOI-critical for automotive Tier-1 production traceability.

FAQ
What is the maximum operating temperature for PDTA123JQC-Q?
The junction temperature (Tj) is rated up to 150 °C, and ambient operating range extends from −55 °C to +150 °C. Derated power dissipation begins above 25 °C ambient, reaching 360 mW at Tamb = 25 °C on standard FR4 (35 µm copper) and 450 mW with enhanced 70 µm copper layout.
Can PDTA123JQC-Q replace a standard PNP transistor like BC857 in existing designs?
Yes-but only if the circuit uses high-side switching and the base drive is compatible with VI(on) = −1.1 to −0.75 V. Unlike BC857, PDTA123JQC-Q has fixed internal resistors; removing external R1/R2 is required, and logic polarity must match PNP RET behavior (active-low input).
Is the DFN1412D-3 package compatible with standard reflow profiles?
Yes. The SOT8009 package is qualified for IPC/JEDEC J-STD-020 moisture sensitivity level 1 and supports standard lead-free reflow profiles (peak 260 °C). Recommended stencil thickness is 0.1 mm, and footprint dimensions are published in Figure 37 of the datasheet.
How does the R2/R1 ratio of 21 affect switching behavior?
An R2/R1 ratio of 21 sets the internal feedback factor, stabilizing base current and ensuring consistent saturation across process and temperature variations. This ratio yields hFE-independent turn-on characteristics and prevents thermal runaway during sustained conduction at 100 mA.
