Product details
Overview
PIMC31PAS-QX from Nexperia is a 50 V, 500 mA NPN/PNP resistor-equipped double transistor (RET) in a DFN2020D-6 (SOT1118D) leadless package with side-wettable flanks. It integrates matched bias resistors (R1 = 1 kΩ, R2 = 10 kΩ) and delivers dual-polarity switching capability for digital control circuits. Used in automotive body electronics for IC input control and load switching, it replaces discrete BC807/BC817 pairs while maintaining AEC-Q101 qualification.
For engineers reviewing the PIMC31PAS-QX datasheet, PIMC31PAS-QX pinout, PIMC31PAS-QX application, or PIMC31PAS-QX equivalent, this page provides verified pin functions, thermal derating curves, DC current gain (hFE ≥ 70), collector-emitter saturation voltage (VCEsat ≤ 100 mV), and validated automotive-grade reliability data - all confirmed against Nexperia's official product data sheet dated 31 August 2023.
Technical Context
This dual-transistor device combines an NPN (TR1) and PNP (TR2) silicon transistor on a single die, each with integrated base biasing resistors enabling direct logic-level drive without external components. The R2/R1 ratio of 10:1 ensures stable current gain control across temperature (−40 °C to 150 °C).
It operates under AEC-Q101 stress qualification with junction temperature up to 150 °C and supports pulsed output currents up to 500 mA per transistor. Thermal resistance ranges from 125 K/W (4-layer PCB, 1 cm² pad) to 348 K/W (single-sided FR4), directly impacting continuous power handling in automotive ambient conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage for both transistors, defining rail compatibility in 12 V/24 V automotive systems. |
| IO | 500 mA - Continuous DC output current per transistor, supporting medium-power switching loads like LEDs, relays, and small solenoids. |
| R1 | 1 kΩ ±30% - Integrated input bias resistor enabling direct TTL/CMOS drive without external pull-up/down networks. |
| R2/R1 | 10 - Fixed internal resistor ratio ensuring predictable base current scaling and consistent hFE operation across temperature. |
| hFE | ≥70 at IC = 50 mA - Minimum DC current gain guarantees reliable saturation under typical digital interface conditions. |
| VCEsat | ≤100 mV at IC = 50 mA, IB = 2.5 mA - Low saturation voltage minimizes conduction loss and self-heating in high-duty-cycle applications. |
| fT | 210 MHz (TR1), 150 MHz (TR2) - Transition frequencies confirm suitability for fast-switching digital interfaces up to ~50 MHz edge rates. |
Pinout & Package
DFN2020D-6 (SOT1118D) is a 2 mm × 2 mm × 0.65 mm thermally enhanced leadless package with side-wettable flanks for automated optical solder-joint inspection. Its ultra-thin profile supports high-density automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1 (NPN); common reference for first transistor's current path. |
| 2 | I1 | Base input for TR1 (NPN); accepts logic-high signal to activate NPN switch. |
| 3 | O2 | Collector output for TR2 (PNP); sinks current when TR2 is active. |
| 4 | GND2 | Emiter connection for TR2 (PNP); common reference for second transistor's current path. |
| 5 | I2 | Base input for TR2 (PNP); accepts logic-low signal to activate PNP switch. |
| 6 | O1 | Collector output for TR1 (NPN); sources current when TR1 is active. |
Key Features
| Feature | Design Value |
|---|---|
| Dual-polarity integration | Single-package NPN + PNP pairing eliminates board space and assembly cost of two discrete devices. |
| Built-in bias resistors | R1 = 1 kΩ and R2 = 10 kΩ reduce BOM count by removing four external resistors per channel. |
| AEC-Q101 qualification | Validated for automotive underhood and cabin applications including engine control modules and lighting drivers. |
| Side-wettable flanks | Enables automated X-ray or AOI inspection of solder joints on bottom-terminated DFN packages. |

Use Value: 500 mA output rating supports direct drive of high-current optocouplers or gate drivers without buffer stages. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar resistor-equipped transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PIMN31PAS-Q | NPN/NPN configuration only; lacks PNP element for complementary switching. | Suitable only where dual-NPN logic is required (e.g., open-collector bus termination). | Select when system requires identical polarity outputs and no sink capability is needed. |
| PIMP31PAS-Q | PNP/PNP configuration only; no NPN transistor for sourcing current. | Applicable only in high-side switching architectures requiring dual-sink outputs. | Choose when driving loads referenced to VCC rather than GND, such as PMOS gate control. |
Compared with PIMC31PAS-QX, PIMN31PAS-Q and PIMP31PAS-Q lack cross-polarity functionality - making them unsuitable for push-pull or level-shifting roles where simultaneous sourcing and sinking is required, unlike the NPN/PNP pairing that enables true bidirectional digital interfacing in a single footprint.

FAQ
What is the maximum operating junction temperature for PIMC31PAS-QX?
The absolute maximum junction temperature is 150 °C, validated under AEC-Q101 thermal stress testing. Derating begins above Tamb = 25 °C per Figure 1 in the datasheet, with total device power dissipation dropping to 730 mW at 25 °C ambient and falling linearly to zero at 150 °C junction temperature.
Can PIMC31PAS-QX replace BC807 and BC817 transistors in existing designs?
Yes - it serves as a drop-in functional replacement for BC807 (PNP) and BC817 (NPN) pairs in digital switching applications. Pin mapping differs, but its integrated R1/R2 network eliminates four external resistors, and the DFN2020D-6 footprint allows layout optimization without sacrificing electrical performance.
How does the side-wettable flank design benefit manufacturing?
The side-wettable flanks on the DFN2020D-6 package allow automated optical inspection (AOI) and X-ray systems to verify solder joint integrity on all six terminals - critical for automotive production lines where zero-defect soldering is mandated. This eliminates reliance solely on post-reflow electrical test for interconnect validation.
Is PIMC31PAS-QX qualified for under-hood automotive use?
Yes - it is fully qualified to AEC-Q101 standards, including high-temperature reverse bias, temperature cycling, and humidity testing. Its −55 °C to +150 °C operating range and 150 °C max Tj rating meet requirements for engine control units, transmission modules, and other under-hood applications.
