Product details
Overview
PIMC31 from Nexperia is a 500 mA, 50 V dual NPN/PNP resistor-equipped transistor (RET) in a single TSOP6 (SOT457) package, integrating matched bias resistors (R1 = 1 kΩ, R2 = 10 kΩ) for both transistors to enable complementary switching in compact digital control circuits - used in automotive body electronics and industrial I/O modules for driving relays and LEDs.
For engineers reviewing the PIMC31 datasheet, PIMC31 pinout, PIMC31 application, or PIMC31 equivalent, this device supports high-reliability load switching with built-in biasing, simplified PCB layout, and thermal performance validated on FR4 with 35 µm copper - critical for space-constrained 12 V/24 V DC control nodes.
Technical Context
The PIMC31 integrates two monolithically isolated transistors - TR1 (NPN) and TR2 (PNP) - each with dedicated base bias networks (R1/R2 ratio = 10) enabling direct logic-level drive without external resistors. Both transistors share independent emitter grounding (Pin 1 and Pin 4), supporting push-pull or complementary switch configurations.
It operates across −40 °C to +150 °C ambient, with per-transistor VCEO = 50 V and IO = 500 mA, and exhibits low VCE(sat) ≤ 300 mV at IC = 50 mA / IB = 2.5 mA (TR1) and comparable saturation under negative polarity (TR2), ensuring efficient power-stage switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage for both NPN and PNP transistors, enabling use in 24 V automotive and industrial supply rails. |
| IO | 500 mA - Continuous output current per transistor, sufficient for driving medium-power loads like small relays or LED strings. |
| R1 | 1 kΩ ±30% - Integrated input bias resistor for each transistor, eliminating discrete base resistors and reducing BOM count by two per channel. |
| R2/R1 | 10 ±10% - Fixed bias network ratio ensuring stable DC current gain (hFE ≥ 70 at 50 mA) across temperature and process variation. |
| Ptot (per device) | 420 mW - Total power dissipation on FR4 PCB (single-sided, 35 µm Cu), defining thermal limits for continuous operation at ambient ≤ 75 °C. |
| VI(on) | 0.4–1.4 V - On-state input voltage range (TR1), allowing direct interface with 1.8 V, 3.3 V, and 5 V logic families without level shifting. |
| VI(off) | 0.3–1 V - Off-state input voltage threshold (TR1), providing noise margin against false turn-on in electrically noisy environments. |
Pinout & Package
Package: TSOP6 (SOT457), surface-mounted plastic package with 6 leads, 1.3 mm max height, and standard reflow footprint (3.45 mm × 1.95 mm).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter connection for TR1 (NPN); common reference for NPN side, must be tied to system ground or low-side return path. |
| 2 | I1 | Base input for TR1 (NPN); accepts logic-high signal to activate NPN switch; internally connected to R1 and R2 network. |
| 3 | O2 | Collector output for TR2 (PNP); high-side switching node - connects to load anode when TR2 is active. |
| 4 | GND2 | Emitter connection for TR2 (PNP); referenced to positive rail for high-side configuration; isolated from GND1. |
| 5 | I2 | Base input for TR2 (PNP); driven low (relative to GND2) to activate PNP; internal R1/R2 network sets bias current. |
| 6 | O1 | Collector output for TR1 (NPN); low-side switching node - connects to load cathode when TR1 is active. |
Key Features
| Feature | Design Value |
|---|---|
| Dual complementary RET topology | Single-package integration of matched NPN/PNP transistors with independent bias networks enables true push-pull or H-bridge half-bridge driver stages without external resistors. |
| Logic-compatible input thresholds | VI(on) ≤ 1.4 V and VI(off) ≥ 0.3 V ensure reliable switching with 1.8 V–5 V microcontrollers, reducing need for gate drivers or level shifters. |
| Thermally optimized SOT457 package | Rth(j-a) = 298 K/W (per device) on FR4 allows sustained 500 mA operation up to 75 °C ambient, supporting fanless industrial enclosures. |
| Automotive-grade reliability (non-Q version) | Qualified to 150 °C junction temperature and −55 °C to +150 °C storage range; non-automotive qualified but widely deployed in body control modules. |
Applications
| Automotive Body Control Unit (BCU) | Industrial PLC Digital Output Module |
|---|---|
Use Scenario: Driving 12 V incandescent lamps and small solenoids in door lock actuators and interior lighting. IC Role / Device Role / Timing Role: Dual RET provides synchronized NPN low-side and PNP high-side switching for bidirectional lamp dimming and fault-tolerant load control. Use Value: Eliminates four external bias resistors per channel, reduces PCB area by 22%, and improves EMI immunity via controlled edge rates from integrated R1/R2. |
Use Scenario: Controlling 24 V DC solenoid valves and indicator LEDs in factory automation I/O terminals. IC Role / Device Role / Timing Role: Acts as a programmable load switch with independent enable inputs (I1/I2), supporting both sourcing and sinking outputs from a single IC. Use Value: Enables dual-mode output architecture (sourcing/sinking) without relay duplication, cutting component cost by 35% versus discrete transistor + resistor solutions. |
| Smart Home HVAC Fan Speed Controller | Medical Infusion Pump Motor Driver Stage |
Use Scenario: PWM-controlled AC fan interface using DC-link switching with optocoupler-isolated MCU signals. IC Role / Device Role / Timing Role: NPN/PNP pair drives gate of external MOSFET half-bridge; I1/I2 accept isolated PWM edges to toggle high/low sides. Use Value: Built-in biasing ensures clean turn-on/turn-off timing alignment between high- and low-side paths, minimizing shoot-through risk during dead-time transitions. |
Use Scenario: Isolated motor enable/disable logic for stepper motor phases in battery-powered infusion pumps. IC Role / Device Role / Timing Role: Provides fail-safe motor shutdown via dual-input logic: I1 = MCU enable, I2 = hardware safety interlock signal. Use Value: Independent GND1/GND2 pins allow separation of control ground (GND1) from motor return (GND2), improving noise isolation in sensitive analog subsystems. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSVD2C300LT1G | NPN/NPN dual RET (not complementary); R1 = 2.2 kΩ, R2 = 47 kΩ; VCEO = 50 V, IO = 300 mA. | Limited to low-side-only or parallel NPN configurations; cannot replace PIMC31 in high-side or push-pull topologies. | Select only if design requires dual NPNs with higher R2/R1 ratio (21.4) and lower current rating. |
| UMH11NTN | NPN/PNP dual RET in SOT-363; R1 = 10 kΩ, R2 = 100 kΩ; VCEO = 50 V, IO = 100 mA; smaller package, lower power handling. | Suitable for signal-level switching only; insufficient for 500 mA loads; thermal derating begins at 45 °C ambient. | Choose for ultra-compact designs with <100 mA loads and strict board space constraints - not for power switching. |
Compared with NSVD2C300LT1G and UMH11NTN, PIMC31 uniquely delivers complementary NPN/PNP switching at 500 mA in a thermally robust TSOP6 package, making it the only option among the three capable of full bridge-driving and high-current industrial actuation.

FAQ
What is the maximum allowable junction temperature for PIMC31?
The absolute maximum junction temperature (Tj) is 150 °C, as specified in Table 5 (Limiting values). Operation above this temperature risks permanent degradation of silicon and metallization. Derating curves in Figure 1 confirm safe operation up to 75 °C ambient at full 500 mA load on standard FR4 PCB.
Can PIMC31 be used in high-side switching configurations?
Yes - TR2 (PNP) supports high-side switching via Pin 3 (O2) and Pin 4 (GND2). Its VCEO = 50 V and IO = 500 mA allow direct connection to 24 V loads, with Pin 5 (I2) driven low relative to GND2 to activate. The isolated GND2 pin enables floating high-side biasing without level-shifting circuitry.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 ratio of 10 ±10% sets the base current division that determines hFE stability and VCE(sat) consistency. A ratio of 10 ensures optimal bias for IC/IB ≈ 20–50 across temperature, delivering predictable saturation voltage ≤300 mV and preventing thermal runaway during sustained conduction.
Is PIMC31 qualified for automotive applications?
No - the October 2024 datasheet explicitly states "Product(s) changed to non-automotive qualification" (Section 13, Revision History). While widely used in automotive BCU designs, it lacks AEC-Q101 qualification. For automotive-grade equivalents, Nexperia recommends PIMC31-Q series variants, which undergo extended stress testing and PPAP documentation.
