Product details
Overview
PIMC31-Q from Nexperia is a dual-channel resistor-equipped transistor (RET) integrating one NPN and one PNP silicon transistor with built-in bias resistors (R1 = 1 kΩ, R2 = 10 kΩ) in a single TSOP6 (SOT457) package. It delivers 500 mA output current per channel, supports ±50 V collector-emitter voltage, and is AEC-Q101 qualified for automotive load switching applications requiring compact, reliable discrete control.
For engineers reviewing the PIMC31-Q datasheet, PIMC31-Q pinout, PIMC31-Q application, or PIMC31-Q equivalent, this device serves as a space- and BOM-optimized solution for bidirectional DC load control-especially where simplified base-drive design, reduced component count, and automotive-grade reliability are critical selection criteria.
Technical Context
The PIMC31-Q integrates two independent RETs: TR1 (NPN) and TR2 (PNP), each with dedicated input (base), output (collector), and emitter (GND) terminals. Its internal resistor network (R1 = 1 kΩ, R2/R1 = 10) enables direct logic-level drive without external biasing components.
It operates across −40 °C to +150 °C ambient temperature, supports 500 mA continuous output per transistor, and features low VCEsat (≤300 mV at IC = 50 mA, IB = 2.5 mA) and defined VI(on)/VI(off) thresholds (0.4–1.4 V on-state, 0.3–1 V off-state) for robust digital interface compatibility.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum safe collector-emitter voltage for both NPN and PNP transistors under open-base conditions. |
| IO | 500 mA - Continuous DC output current capability per channel, enabling direct driving of medium-power loads (e.g., relays, LEDs, small solenoids). |
| R1 | 1 kΩ (0.7–1.3 kΩ) - Input bias resistor value defining base current path for logic-compatible turn-on. |
| R2/R1 | 10 (9–11) - Fixed resistor ratio ensuring stable current gain and predictable saturation behavior across temperature. |
| hFE | 70 min - Minimum DC current gain at VCE = 5 V, IC = 50 mA, enabling reliable switching with modest base drive. |
| VCEsat | ≤300 mV - Low saturation voltage minimizes power loss and heat generation during conduction. |
| VI(on) | 0.4–1.4 V - Validated on-state input voltage range compatible with 1.8 V, 3.3 V, and 5 V logic families. |
Pinout & Package
Package: TSOP6 (SOT457), surface-mounted plastic package with 6 leads, 1.7 mm × 2.5 mm footprint, and 0.65 mm lead pitch. Designed for reflow and wave soldering per IPC-7351B standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for TR1 (NPN); common reference for first channel. |
| 2 | I1 | Base input for TR1 (NPN); driven through internal R1–R2 network. |
| 3 | O2 | Collector output for TR2 (PNP); high-side switching node. |
| 4 | GND2 | Emiter connection for TR2 (PNP); common reference for second channel. |
| 5 | I2 | Base input for TR2 (PNP); driven through internal R1–R2 network. |
| 6 | O1 | Collector output for TR1 (NPN); low-side switching node. |
Key Features
| Feature | Design Value |

| AEC-Q101 qualification | Validated for automotive applications including engine control modules, body electronics, and lighting systems per stress test requirements. |
| Logic-level compatible inputs | VI(on) ≤1.4 V and VI(off) ≥0.3 V enable direct interfacing with microcontrollers and ASICs without level-shifting circuitry. |
| Thermal derating support | Per-device Ptot = 420 mW at Tamb ≤25 °C with Rth(j-a) = 298 K/W, supporting sustained operation in confined automotive enclosures. |
| Low saturation voltage | VCEsat ≤300 mV ensures <150 mW conduction loss at 500 mA, minimizing thermal stress in high-duty-cycle switching. |
Applications
| Automotive Body Control Module | Industrial PLC Output Stage |
|---|---|
Use Scenario: Controlling door lock actuators, mirror heaters, and interior lighting via MCU GPIO pins. IC Role / Device Role / Timing Role: Dual-channel load switch providing isolated high- and low-side drive for bidirectional actuator control. Use Value: Eliminates need for separate NPN and PNP drivers and four external bias resistors, cutting BOM cost by ~$0.08/unit and layout area by 2.2 mm². | Use Scenario: Driving 24 V DC solenoid valves and indicator LEDs in factory automation I/O modules. IC Role / Device Role / Timing Role: Discrete-level interface between industrial controller outputs and field devices requiring galvanically separated switching paths. Use Value: Enables 500 mA per channel switching at <300 mV saturation drop, reducing thermal load versus standard BJTs and avoiding MOSFET gate-drive complexity. |
| Automotive HVAC Blower Control | Smart Home Power Management |
Use Scenario: PWM-controlled fan speed regulation using MCU-driven low-side (TR1) and high-side (TR2) switching. IC Role / Device Role / Timing Role: Bidirectional DC switching element supporting complementary drive topology for efficient motor commutation. Use Value: Built-in R1/R2 ratio ensures consistent turn-on/turn-off timing across temperature, improving PWM fidelity and reducing EMI vs. discrete resistor networks. | Use Scenario: Managing USB-C PD accessory power rails and status LEDs in smart hubs and docking stations. IC Role / Device Role / Timing Role: Compact logic-level load switch for 5 V/3.3 V system rail control and fault-isolated LED signaling. Use Value: AEC-Q101 qualification provides extended lifetime and failure-rate predictability beyond consumer-grade alternatives, supporting 10-year product warranties. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual RET switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSVD5112MUTAG | Single-channel NPN RET (500 mA, 50 V); no integrated PNP section. | Requires external PNP or complementary driver for bidirectional control. | Select when only unidirectional switching is needed and board space allows two separate RETs. |
| UMX23T1G | PNP+NPN pair with R1 = 2.2 kΩ, R2 = 47 kΩ (R2/R1 ≈ 21.4); lower hFE (min 56). | Higher input resistance increases noise immunity but reduces drive strength at low VCC. | Prefer for 3.3 V logic systems where higher VI(on) margin is required, but verify saturation performance at 500 mA. |
Compared with NSVD5112MUTAG and UMX23T1G, the PIMC31-Q uniquely integrates matched NPN/PNP RETs with identical R1/R2 values and AEC-Q101 qualification in one package-enabling true bidirectional switching without layout compromise or thermal mismatch between channels.

FAQ
What is the maximum operating junction temperature for PIMC31-Q?
The absolute maximum junction temperature (Tj) is 150 °C, as specified in the Limiting Values table. Derating begins above Tamb = 25 °C, with per-device total power dissipation dropping to zero at Tamb = 175 °C per the published derating curve. Thermal resistance from junction to ambient is 298 K/W on FR4 PCB.
Can PIMC31-Q be used in 12 V automotive battery-sensing circuits?
Yes-its VCEO rating of 50 V exceeds typical automotive battery transient spikes (up to 40 V), and its VI(off) threshold (≥0.3 V) ensures reliable cutoff during cold-crank conditions (down to −40 °C). The device is explicitly qualified per AEC-Q101 for such environments.
Does PIMC31-Q support PWM switching at frequencies above 10 kHz?
Yes-TR1 (NPN) and TR2 (PNP) exhibit typical collector capacitance of 7 pF and 11 pF respectively, enabling clean switching up to 100 kHz in resistive loads. For inductive loads, external flyback diodes are required; rise/fall times are not specified but VCEsat and hFE data confirm suitability for standard MCU PWM rates.
How does the R2/R1 ratio affect switching behavior?
The fixed R2/R1 ratio of 10 defines the internal base current division, stabilizing hFE-dependent saturation and ensuring consistent VI(on)/VI(off) thresholds across temperature. This eliminates variability seen with discrete resistor networks and guarantees predictable turn-on delay and conduction loss within datasheet limits.
