Product details
Overview
PIMN32 from Nexperia is an NPN/NPN resistor-equipped double transistor (RET) in SOT457 (SC-74) package, rated for 50 V VCEO, 500 mA output current per transistor, with built-in bias resistors R1 = 2.2 kΩ and R2 = 10 kΩ. It functions as a dual digital switching element for IC input control and load switching in compact PCB designs.
For engineers reviewing the PIMN32 datasheet, PIMN32 pinout, PIMN32 application, or PIMN32 equivalent, this device serves as a space- and BOM-optimized replacement for discrete base-resistor transistor pairs in low-voltage logic interfacing and 500 mA switching applications requiring simplified drive circuitry.
Technical Context
The PIMN32 integrates two matched NPN transistors with on-chip base bias networks-R1 (input resistor) and R2 (feedback resistor)-enabling direct TTL/CMOS-level input drive without external base resistors. Each transistor operates independently with open-base VCEO = 50 V and IO = 500 mA rating.
Its SC-74 (TSOP6) package supports high-density mounting and features six terminals with dedicated GND, input, and collector pins per transistor. Thermal resistance Rth(j-a) is 298 K/W per device on FR4 PCB, enabling stable operation up to 150 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 50 V - Maximum collector-emitter voltage before breakdown; defines safe switching range for 24 V and 36 V logic-controlled loads. |
| IO | 500 mA - Continuous DC output current per transistor; supports driving relays, LEDs, or small solenoids directly. |
| R1 | 2.2 kΩ - Input bias resistor value; sets base current for ~0.7 mA at 1.5 V input, enabling direct CMOS/TTL compatibility. |
| R2/R1 ratio | 4.55 - Feedback-to-input resistor ratio; stabilizes operating point against β variation and temperature drift. |
| VCE(sat) | 100 mV @ IC = 50 mA, IB = 2.5 mA - Low saturation voltage minimizes power loss and heat generation during on-state operation. |
| fT | 225 MHz - Transition frequency of internal transistors; ensures reliable switching up to ~10–20 MHz digital signal rates. |
| Ptot (per device) | 420 mW @ Tamb ≤ 25 °C - Total power dissipation limit; defines thermal headroom for dual-transistor operation on standard FR4 PCB. |
Pinout & Package
Package: SOT457 (SC-74 / TSOP6), 6-pin surface-mount plastic package with 0.95 mm pitch, 2.7 mm × 1.7 mm footprint, and exposed pad-compatible layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | GND1 | Emiter connection for transistor TR1; common reference for first switch channel. |
| 2 | I1 | Base input for TR1; accepts logic-level voltage via integrated R1 resistor. |
| 3 | O2 | Collector output for TR2; high-side switching node for second load path. |
| 4 | GND2 | Emiter connection for transistor TR2; independent ground return for second channel. |
| 5 | I2 | Base input for TR2; logic-driven input with same R1/R2 bias network as I1. |
| 6 | O1 | Collector output for TR1; primary switching node for first load path. |
Key Features
| Feature | Design Value |
|---|---|
| Dual NPN RET architecture | Two fully independent NPN transistors with matched R1/R2 bias networks eliminate need for 4 external resistors in discrete implementations. |
| 500 mA per channel | Supports direct switching of medium-current loads (e.g., LED strings, small relays) without external driver stages. |
| Input voltage range −5 V to +12 V | Withstands negative transients and interfaces safely with mixed-voltage systems including 3.3 V, 5 V, and 12 V logic families. |
| VI(off) = 0.65 V typical | Ensures robust turn-off margin against noise and leakage, preventing unintended conduction in noisy industrial environments. |
| hFE ≥ 70 @ IC = 50 mA | Guarantees sufficient current gain for saturated switching across industrial temperature range (−40 °C to +125 °C). |
Applications
| Industrial PLC I/O Modules | Automotive Body Control Units |

Use Scenario: Controlling interior lighting zones and window lift motors in non-safety-critical body electronics. IC Role / Device Role: Dual low-side switch for PWM-dimmed LED clusters and brushed DC motor direction control. Use Value: Enables 500 mA per channel switching with guaranteed VCE(sat) ≤ 100 mV, minimizing thermal stress and eliminating need for heatsinking in confined modules. |
| Consumer Appliance Control Boards | IoT Sensor Hub Interfaces |
|
Use Scenario: Managing relay coils, buzzer drivers, and display backlight segments in washing machine and HVAC mainboards. IC Role / Device Role: Compact dual switch for isolating MCU I/O from higher-power peripherals while maintaining logic compatibility. Use Value: Built-in R1/R2 eliminates solder joint reliability risks associated with discrete resistor placement and reduces test points required during functional testing. |
Use Scenario: Interfacing ESP32 or nRF52 GPIOs to external sensors requiring active pull-up/pull-down or signal conditioning. IC Role / Device Role: Dual-purpose buffer and level translator for bidirectional sensor enable lines and interrupt signals. Use Value: VI(on)/VI(off) specs ensure clean logic thresholds across −40 °C to +85 °C ambient, supporting reliable wake-up and sleep-mode signaling in battery-powered edge nodes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC846BDW1T1G | Discrete dual NPN without bias resistors; requires external R1/R2 network; hFE min = 220 vs. PIMN32's 70. | Higher gain but increased BOM count and layout complexity; less suitable for ultra-compact or high-volume cost-sensitive designs. | Select when precise bias tuning or higher β is required; avoid if minimizing pick-and-place steps is critical. |
| PIMC32 | NPN/PNP complement; identical package and bias values but opposite polarity per channel; VCEO = 50 V, IO = 500 mA. | Enables complementary push-pull or H-bridge configurations where one channel must sink and the other source current. | Choose for bidirectional load control or when interfacing with both high- and low-side referenced signals in same subsystem. |
Compared with BC846BDW1T1G, PIMN32 trades off gain flexibility for integration and assembly efficiency; compared with PIMC32, it provides matched NPN behavior essential for parallel load switching or cascaded logic buffering without polarity inversion.

FAQ
What is the maximum allowable input voltage at I1 or I2 pins?
The absolute maximum input voltage is −5 V to +12 V per pin, as specified in Table 5 (Limiting Values). This range accommodates transient overshoots and mixed-voltage system interfacing, but sustained operation above 5.5 V should include series current limiting if driving into capacitive loads to prevent exceeding R1 power rating.
Can PIMN32 be used in linear amplifier mode?
No-PIMN32 is characterized and qualified exclusively for switching operation. Its R1/R2 network is optimized for saturated on/off states, and hFE and VCE(sat) parameters are specified only under switching conditions. Linear operation may cause thermal instability and is not supported by datasheet characterization.
Is the SOT457 package lead-free and RoHS compliant?
Yes-PIMN32 meets RoHS Directive 2011/65/EU and is manufactured with lead-free terminations and halogen-free molding compound. The device is qualified for reflow soldering per J-STD-020, with peak temperature tolerance up to 260 °C for 30 seconds.
How does thermal performance differ between per-transistor and per-device ratings?
Per-transistor Ptot = 290 mW assumes single-channel operation; per-device Ptot = 420 mW reflects total dissipation when both transistors operate simultaneously. Derating follows Fig. 1: power must be reduced linearly above 25 °C ambient, reaching zero at 175 °C for per-device rating on standard FR4 PCB.
