Product details
Overview
PIMC31F from Nexperia is a 500 mA, 50 V dual NPN/PNP resistor-equipped transistor (RET) in a 6-pin TSOP6 (SOT457) package, integrating matched bias resistors (R1 = 1 kΩ, R2 = 10 kΩ) for both transistors to enable direct logic-level switching without external base resistors. It serves as a compact, dual-polarity load switch in automotive and industrial digital control circuits, supporting bidirectional current handling with VCEO = 50 V and IO = 500 mA per transistor.
For engineers reviewing the PIMC31F datasheet, PIMC31F pinout, PIMC31F application, or PIMC31F equivalent, this device is selected for space-constrained, low-component-count switching designs requiring verified dual-NPN/PNP functionality, built-in resistor ratios (R2/R1 = 10), and thermal performance validated on FR4 PCBs with Rth(j-a) = 298 K/W per device.
Technical Context
The PIMC31F integrates two monolithically fabricated transistors - TR1 (NPN) and TR2 (PNP) - sharing no internal connection except common ground terminals (Pin 1 and Pin 4). Each includes dedicated input (base) and output (collector) pins with integrated R1–R2 bias networks, eliminating need for discrete base resistors in standard switching configurations.
Its VI(on) = 0.4–1.4 V (TR1) and –0.4 to –1.4 V (TR2) enables direct interfacing with 3.3 V/5 V logic; VCE(sat) ≤ 300 mV at IC = 50 mA confirms low-loss switching; and hFE ≥ 70 ensures robust current gain across –40 °C to +100 °C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; supports 24 V industrial bus and 12 V automotive loads with margin. |
| IO | 500 mA - Continuous output current per transistor; sufficient for driving relays, LEDs, and small solenoids. |
| R1 | 1 kΩ ±30% - Integrated input bias resistor; sets base current for predictable turn-on without external components. |
| R2/R1 ratio | 10 ±10% - Fixed feedback-to-input resistor ratio; stabilizes operating point against temperature and process variation. |
| VCE(sat) | ≤300 mV at IC = 50 mA - Low saturation voltage minimizes power loss and self-heating during conduction. |
| hFE | ≥70 at VCE = 5 V, IC = 50 mA - Ensures reliable current amplification under typical digital drive conditions. |
| Ptot (per device) | 420 mW at Tamb ≤ 25 °C - Total dissipation limit for both transistors on standard FR4 PCB; defines thermal design envelope. |
Pinout & Package
Package: TSOP6 (SOT457), surface-mount plastic package with 6 leads, 1.3 mm max height, and standard reflow footprint per Figure 14.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emitter terminal of TR1 (NPN); common reference for NPN side; must be connected to system ground or low-side return path. |
| 2 | I1 | Base input of TR1 (NPN); accepts logic-high signal to activate NPN switch; internally pulled through R1 to GND1. |
| 3 | O2 | Collector output of TR2 (PNP); high-side switching node; sinks current when TR2 is active. |
| 4 | GND2 | Emitter terminal of TR2 (PNP); common reference for PNP side; connects to load return or floating ground in high-side configuration. |
| 5 | I2 | Base input of TR2 (PNP); accepts logic-low signal (or open) to activate PNP switch; internally pulled through R1 to GND2. |
| 6 | O1 | Collector output of TR1 (NPN); low-side switching node; sources current to load when TR1 is active. |
Key Features
| Feature | Design Value |
|---|---|
| Dual polarity integration | Monolithic NPN + PNP pair in single TSOP6 package enables complementary switching without inter-device timing skew or layout mismatch. |
| Built-in resistor network | R1 = 1 kΩ and R2 = 10 kΩ per transistor eliminate four external resistors, reducing BOM count and PCB area by >30% vs discrete solution. |
| Logic-compatible input thresholds | VI(on) = 0.4–1.4 V (NPN) and –0.4 to –1.4 V (PNP) ensure clean turn-on with standard CMOS/TTL outputs without level-shifting. |
| Thermally optimized packaging | Rth(j-a) = 298 K/W (per device) on FR4 allows 420 mW total dissipation - supports sustained 500 mA operation with minimal heatsinking. |
| Automotive-capable construction | Qualified per AEC-Q101 (note: non-automotive version per revision v.2; automotive-grade PIMC31-Q available separately). |
Applications
| Industrial PLC Output Stage | Automotive Body Control Module |
|---|---|
|
Use Scenario: Driving 24 V DC solenoids and indicator LEDs in programmable logic controller output modules. IC Role / Device Role / Timing Role: Dual RET acts as low-side (TR1) and high-side (TR2) driver, enabling push-pull control of bidirectional loads. Use Value: Eliminates need for separate NPN/PNP drivers and four bias resistors, reducing component count by 6 parts and saving >2.5 mm² PCB area per channel. |
Use Scenario: Controlling door lock actuators and interior lighting in vehicle body electronics. IC Role / Device Role / Timing Role: TR1 switches ground path for lamps; TR2 drives positive rail for latching relays - both synchronized via shared MCU GPIO. Use Value: VI(off) ≤ 1 V ensures full cutoff at battery voltages up to 16 V, preventing unintended activation during cold-cranking transients. |
| Smart Sensor Interface | Consumer Appliance Motor Control |
|
Use Scenario: Level-shifting and isolation between microcontroller I/O and analog sensor supply rails in HVAC control units. IC Role / Device Role / Timing Role: TR2 provides high-side enable for 3.3 V sensor bias; TR1 grounds fault-reporting lines with hysteresis via R2 feedback. Use Value: R2/R1 = 10 ratio delivers stable bias point across –40 °C to +85 °C, maintaining sensor accuracy without calibration drift. |
Use Scenario: Driving unidirectional brushed motors in washing machines and vacuum cleaners using half-H-bridge topology. IC Role / Device Role / Timing Role: TR1 controls motor low-side; TR2 enables brake or direction reversal via auxiliary coil - both operated from same PWM source. Use Value: VCE(sat) ≤ 300 mV limits conduction loss to <150 mW at 500 mA, reducing thermal stress in sealed enclosure environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual RET applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PIMN31 | NPN/NPN complement (not NPN/PNP); identical R1/R2 values and package but lacks PNP transistor. | Suitable only for dual low-side switching; cannot replace PIMC31F in high-side or push-pull configurations. | Select only when circuit requires two independent NPN switches with shared ground and no high-side capability. |
| EMH12T2R | 6-pin SOT-363 package; R1 = 2.2 kΩ, R2 = 47 kΩ (R2/R1 ≈ 21.4); lower IO = 100 mA per transistor. | Targeted at signal-level switching (e.g., I²C buffering), not power loads; unsuitable for 500 mA solenoid or motor drive. | Choose only for low-current, high-impedance logic interface where higher resistor ratio improves noise immunity. |
Compared with PIMN31 and EMH12T2R, the PIMC31F uniquely delivers matched NPN/PNP switching at 500 mA in a thermally efficient TSOP6 package - making it the only option among the three for compact, bidirectional load control in industrial and automotive power interfaces.

FAQ
What is the maximum junction temperature rating for PIMC31F?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in the Absolute Maximum Ratings table. Operation above this value risks permanent device degradation. Derating begins at Tamb > 25 °C per the power derating curve (Figure 1), where Ptot decreases linearly to zero at 175 °C ambient.
Can PIMC31F be used in high-side switching configurations?
Yes - TR2 (PNP) is explicitly designed for high-side switching: Pin 4 (GND2) serves as its emitter reference, Pin 5 (I2) is its base input, and Pin 3 (O2) is its collector output. When I2 is pulled low relative to GND2, TR2 conducts, allowing current flow from O2 to GND2 - ideal for sourcing current to loads referenced to ground.
Is PIMC31F qualified for automotive applications?
No - per Revision v.2 (October 2024), PIMC31F is explicitly marked as non-automotive qualified. Nexperia offers the automotive-qualified PIMC31-Q variant, which undergoes AEC-Q101 stress testing and supports extended temperature range and PPAP documentation. Use of PIMC31F in automotive systems voids warranty and is unsupported.
How does the R2/R1 ratio affect switching behavior?
The R2/R1 = 10 ratio forms a voltage divider that provides negative feedback to stabilize the base-emitter voltage, improving turn-off consistency and reducing sensitivity to hFE variation. This results in VI(off) ≤ 1 V across temperature, ensuring reliable cutoff even with wide hFE spreads (70–300), unlike bare transistors requiring precise external bias tuning.
