Product details
Overview
PDTA124EQB-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 two 22 kΩ bias resistors (R1 = R2), delivers hFE ≥ 60 at IC = −5 mA, achieves VCE(sat) ≤ −100 mV at IC = −10 mA/IB = −0.5 mA, and is AEC-Q101 qualified for automotive load switching and IC input control.
For engineers reviewing the PDTA124EQB-Q datasheet, PDTA124EQB-Q pinout, PDTA124EQB-Q application, or PDTA124EQB-Q equivalent, this device serves as a space-optimized, AOI-compatible digital switch with built-in base biasing-reducing external component count and simplifying PCB layout in cost-sensitive, high-reliability embedded systems.
Technical Context
This PNP RET uses an integrated dual-resistor network (R1 = R2 = 22 kΩ) to provide fixed-current base biasing, eliminating discrete base resistors and enabling direct logic-level drive from 3.3 V or 5 V microcontrollers. Its ultra-thin 0.48 mm profile and side-wettable flanks support automated optical inspection and high-density reflow assembly.
The device operates across −55 °C to +150 °C ambient, maintains VCEO = −50 V and IO = −100 mA absolute maximum ratings, and exhibits low VCE(sat) and well-defined VI(on)/VI(off) thresholds-ensuring predictable turn-on/turn-off behavior in digital interface and load-control circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage under open-base condition; enables use in 24 V automotive and industrial supply rails. |
| IO | −100 mA - Continuous DC output current capability; sufficient for driving LEDs, relays, small solenoids, or logic inputs. |
| hFE | ≥60 at VCE = −5 V, IC = −5 mA - Guaranteed current gain ensures reliable saturation with minimal base drive current. |
| VCE(sat) | ≤ −100 mV at IC = −10 mA, IB = −0.5 mA - Low saturation voltage minimizes power loss and heat generation in switching applications. |
| R1 / R2 | 22 kΩ / 22 kΩ - Matched internal bias resistors simplify design, eliminate external components, and ensure consistent switching thresholds. |
| Package | DFN1110D-3 (SOT8015) - 1.1 × 1.0 × 0.48 mm leadless package with side-wettable flanks for AOI-compatible solder joint inspection. |
| AEC-Q101 | Qualified - Meets stress test requirements for automotive discrete semiconductors; suitable for under-hood and body-control modules. |
Pinout & Package
DFN1110D-3 (SOT8015) is a 3-terminal, leadless, ultra-thin surface-mount package with side-wettable flanks for automated optical inspection. Dimensions: 1.1 mm × 1.0 mm × 0.48 mm; pitch: 0.65 mm; body height: 0.48 mm; wettable flank height: 0.20 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Input (base) | Connected internally to R1; accepts logic-level control signal; defines turn-on threshold via resistor divider network. |

| 3 | Output (collector) | Switched high-side output node; sinks load current when active; connects to positive rail via external load. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated bias resistors | R1 = R2 = 22 kΩ - Eliminates need for two external SMT resistors, reducing BOM count and placement cost. |
| Ultra-low profile | 0.48 mm max height - Enables use in slim-profile consumer and automotive modules where Z-height is constrained. |
| Side-wettable flanks | 0.20 mm flank height - Supports automated optical inspection of solder joints without X-ray, improving manufacturing yield. |
| AEC-Q101 qualification | Qualified per stress test standard - Validated for automotive temperature, humidity, and lifetime reliability requirements. |
| 100 mA output rating | Rated continuous IO = −100 mA - Supports direct drive of medium-current loads such as status LEDs, small relays, and logic buffers. |
Applications
| Automotive Body Control | Industrial Sensor Interface |
|---|---|
|
Use Scenario: Controlling door lock actuators and interior lighting in vehicle body control modules (BCM). IC Role / Device Role / Timing Role: High-side PNP switch that interfaces MCU GPIOs to 12 V loads, providing level-shifted, current-limited drive.

IC Role / Device Role / Timing Role: Digital buffer and level translator between 5 V sensor logic and 3.3 V microcontroller inputs. Use Value: Predictable VI(on)/VI(off) thresholds (−1.1 V to −0.8 V) ensure clean logic transitions; low VCE(sat) minimizes voltage drop in signal path. |
| Consumer Power Management | Medical Diagnostic Equipment |
|
Use Scenario: Enabling/disabling auxiliary power rails in portable ultrasound or patient monitor subsystems. IC Role / Device Role / Timing Role: Load switch for controlled power sequencing of peripheral ICs during startup and shutdown. Use Value: 100 mA rating supports multiple low-power peripherals; DFN1110D-3 footprint saves board space in compact handheld enclosures. |
Use Scenario: Driving LED indicators and buzzer alerts in FDA-cleared diagnostic devices requiring long-term reliability. IC Role / Device Role / Timing Role: Fail-safe indicator driver with defined off-state leakage (≤ −180 µA at Tj = 150 °C). Use Value: Low ICEO ensures no false triggering during standby; AEC-Q101 qualification correlates with extended MTBF in safety-critical applications. |
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 |
|---|---|---|---|
| PDTC124EQB-Q | NPN complement with identical R1/R2 = 22 kΩ, same package, but opposite polarity and VCEO = +50 V. | Used where low-side switching or sink configuration is preferred over high-side PNP sourcing. | Select when load must be connected between VCC and collector (NPN sink), rather than between emitter and ground (PNP source). |
| BC857B-Q | Discrete PNP transistor (no built-in resistors); requires external base biasing; hFE = 200–450; same SOT323 package. | Offers higher gain and lower VCE(sat), but increases component count and layout complexity. | Choose when precise gain control or minimal saturation voltage is critical, and additional resistors can be accommodated. |
Compared with PDTC124EQB-Q, PDTA124EQB-Q provides high-side sourcing capability ideal for grounded-load configurations; versus BC857B-Q, it trades off some gain and VCE(sat) for reduced BOM, smaller footprint, and simplified layout-making it optimal for cost- and space-constrained digital switching.

FAQ
What is the maximum operating temperature for PDTA124EQB-Q?
The PDTA124EQB-Q has a specified junction temperature limit of 150 °C and an ambient operating range of −55 °C to +150 °C. Its thermal resistance Rth(j-a) is 298 K/W on a 70 µm copper FR4 PCB, enabling reliable operation in under-hood automotive environments when properly heatsinked or spaced.
Can PDTA124EQB-Q be used with 3.3 V logic controllers?
Yes. The device's VI(on) is −1.7 V typical at IC = −5 mA, meaning it fully saturates when driven by a 3.3 V GPIO pulled low through a series resistor or directly-provided the controller can sink ≥0.23 mA (per test conditions). Its VI(off) of −1.1 V ensures robust noise margin against false turn-on.
How does the DFN1110D-3 package support automated optical inspection?
The DFN1110D-3 package features side-wettable flanks with 0.20 mm vertical height, allowing solder paste to wick up the sidewall during reflow. This creates a visible fillet detectable by standard AOI systems-eliminating the need for costly X-ray inspection while ensuring solder joint integrity in high-volume manufacturing.
Is there a recommended PCB footprint for PDTA124EQB-Q?
Yes. Nexperia specifies a reflow footprint with 0.65 mm pad pitch, 0.34 mm pad width, 0.88 mm pad length, and 0.1 mm stencil thickness. The land pattern includes solder mask-defined pads and 0.22 mm solder resist dams to prevent bridging-details are provided in Figure 31 of the official datasheet (Rev. 1, 2021).
