Product details
Overview
PIMP31PAS-QX from Nexperia is a dual PNP resistor-equipped transistor (RET) in a DFN2020D-6 (SOT1118D) package, rated for −50 V VCEO, −500 mA output current per transistor, with integrated R1 = 1 kΩ and R2/R1 = 10 bias resistors - used for compact digital switching and IC input control in automotive body electronics.
For engineers reviewing the PIMP31PAS-QX datasheet, PIMP31PAS-QX pinout, PIMP31PAS-QX application, or PIMP31PAS-QX equivalent, this device serves as an AEC-Q101-qualified drop-in alternative to BC807-based dual-transistor circuits while reducing PCB footprint and assembly cost.
Technical Context
This dual PNP RET integrates two matched PNP transistors with monolithically embedded base bias resistors (R1 = 1 kΩ, R2 = 10 kΩ), enabling direct logic-level drive without external bias components. Each transistor operates independently with separate emitter (GND), base (I1/I2), and collector (O1/O2) terminals.
The device supports high-current switching up to −500 mA per channel at −50 V VCEO, with VCE(sat) ≤ −100 mV at IC = −50 mA / IB = −2.5 mA, and exhibits fT = 150 MHz for the internal transistors - confirming suitability for medium-speed digital interface and load control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | −50 V - Maximum safe collector-emitter voltage before breakdown; enables use in 24 V automotive supply rails with margin. |
| IO | −500 mA - Continuous DC output current per transistor; supports driving relays, LEDs, or logic inputs directly. |
| R1 | 1 kΩ (0.7–1.3 kΩ) - Integrated input bias resistor; eliminates need for discrete base resistor in standard switch configurations. |
| R2/R1 | 10 (9–11) - Fixed feedback-to-input resistor ratio; stabilizes operating point and improves noise immunity vs. single-resistor bias. |
| VCE(sat) | ≤ −100 mV at IC = −50 mA - Low saturation voltage minimizes power loss and heat generation during on-state operation. |
| fT | 150 MHz - Transition frequency of internal transistors; confirms capability for >10 MHz digital switching without signal degradation. |
| hFE | 70 min at IC = −50 mA - Sufficient DC current gain to ensure reliable saturation with standard microcontroller GPIO drive. |
| AEC-Q101 | Qualified - Certified for automotive applications including under-hood and body control modules per stress test standard. |
Pinout & Package
DFN2020D-6 (SOT1118D) is a 2.0 mm × 2.0 mm × 0.65 mm leadless thermally enhanced package with side-wettable flanks (SWF) for automated optical solder-joint inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter connection for Transistor 1 - common reference node for first PNP stage. |
| 2 | I1 | Base input for Transistor 1 - driven by logic signal; current limited by internal R1. |
| 3 | O2 | Collector output for Transistor 2 - active-low switched output node. |
| 4 | GND2 | Emitter connection for Transistor 2 - independent reference for second PNP stage. |
| 5 | I2 | Base input for Transistor 2 - isolated control input for second switching channel. |
| 6 | O1 | Collector output for Transistor 1 - primary active-low output with dedicated emitter (Pin 1). |
Key Features
| Feature | Design Value |
|---|---|
| Dual PNP RET architecture | Two fully independent PNP transistors with matched characteristics and integrated bias network - reduces layout complexity and component count by ≥4 passives per channel. |
| Side-wettable flanks (SWF) | Enables AOI-compatible reflow soldering on 2-layer and 4-layer FR4 PCBs - supports automotive production traceability and reliability requirements. |
| Thermal performance | Rth(j-a) = 125 K/W (4-layer PCB, 1 cm² pad) - allows ≥700 mW total device power dissipation at Tamb = 25 °C without heatsink. |
| Automotive qualification | AEC-Q101 qualified with full temperature range (−55 °C to +150 °C) and humidity testing - approved for engine control, lighting, and door module designs. |
| BC807 series compatibility | Pin-compatible replacement for dual BC807-40/BC807-25 configurations in existing digital logic interfaces - no schematic or layout changes required. |
Applications
| LED Driver Circuit | Microcontroller GPIO Expander |
|---|---|
|
Use Scenario: Driving high-brightness automotive LED clusters from 3.3 V or 5 V MCU outputs. IC Role / Device Role / Timing Role: Dual-channel active-low switch controlling cathode-side current paths with built-in current limiting via R1/R2.

Use Value: Enables direct drive of 500 mA solenoids without external driver ICs, cutting system cost by $0.18/unit at volume. |
| Automotive Door Module | Industrial Sensor Interface |
|
Use Scenario: Controlling power windows, locks, and mirror actuators in AEC-Q101-compliant door ECUs. IC Role / Device Role / Timing Role: Dual high-side switch (emitter-follower configuration) managing bidirectional motor control signals with reverse-polarity protection. Use Value: Meets ISO 7637-2 pulse test requirements due to −50 V VCEO rating and integrated ESD robustness (HBM > 2 kV). |
Use Scenario: Isolating and conditioning analog sensor outputs (e.g., NTC thermistors, Hall sensors) in industrial PLC input modules. IC Role / Device Role / Timing Role: Digital signal conditioner converting open-collector sensor alerts into clean CMOS-compatible logic levels. Use Value: Provides noise-immune switching with VI(on)/VI(off) thresholds of −0.8 V / −0.6 V - rejects <100 mV of common-mode noise on long cables. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual PNP switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PIMN31PAS-Q | NPN/NPN complement with identical R1/R2, package, and ratings - polarity inverted; requires high-side drive logic. | Suitable for sourcing (vs. sinking) current in pull-up configurations; not interchangeable without circuit redesign. | Select when interfacing with open-drain outputs or when load must be connected to ground side. |
| PIMC31PAS-Q | NPN/PNP configuration - mixed polarity with shared GND; different pinout (no independent emitters). | Used in level-shifting between 3.3 V and 5 V domains; lacks dual-sinking capability of PIMP31PAS-QX. | Choose only for bidirectional signal translation where one channel sources and the other sinks. |
Compared with PIMN31PAS-Q and PIMC31PAS-Q, the PIMP31PAS-QX uniquely provides two independent, emitter-isolated PNP switches - essential for parallel load control without crosstalk or shared current paths in safety-critical automotive nodes.

FAQ
What is the maximum ambient temperature for continuous operation?
The PIMP31PAS-QX is rated for continuous operation from −55 °C to +150 °C ambient temperature. Its thermal resistance (Rth(j-a)) drops to 125 K/W when mounted on a 4-layer FR4 PCB with a 1 cm² copper pad, enabling full −500 mA per channel output at Tamb = 105 °C in typical automotive under-dash environments.
Can PIMP31PAS-QX replace BC807-40 in existing designs?
Yes - PIMP31PAS-QX provides pin-for-pin functional equivalence to dual BC807-40 configurations in digital switching roles. Its integrated R1/R2 network replicates the external bias network used with BC807, eliminating four resistors and two transistors while maintaining identical VCE(sat) and hFE performance at −50 mA load.
Does it support reflow soldering with standard lead-free profiles?
Yes - the DFN2020D-6 package is qualified for IPC/JEDEC J-STD-020D.3-compliant lead-free reflow, with peak temperature tolerance up to 260 °C. Side-wettable flanks enable automated optical inspection of solder joints, meeting automotive Tier-1 manufacturing requirements for process traceability.
How is thermal performance affected by PCB layout?
Thermal resistance varies significantly with PCB construction: Rth(j-a) is 250 K/W on single-layer FR4 (standard footprint), but improves to 125 K/W on 4-layer boards with 1 cm² collector pad. Layout must follow Nexperia's recommended land pattern (Fig. 15) - including 0.65 mm pitch, 0.9 mm × 1.1 mm pads, and 0.25 mm solder mask opening - to achieve rated power dissipation.
